cally rack-mounted right below the main assem-
bly radio chassis. The T800 is made up of two separate power supply units joined in a single chassis:
A T807 using convection cooling is rated up to 15A. It supplies all the radio modules other than the Power Amplifier. A T808 using convection and fan cooling is rated up to 25A. It supplies only the Power Amplifier module. Normally used at room ambient temperatures, they can operate within specifications over a range of 10 to +60 C. Note: Internal over-temperature protection shuts down the main transformer above 105 degrees Celsius. Both power supply modules are internally con-
nected to ground via their individual, rear-
connected, seven-foot standard 120 VAC power cords. Nevertheless, each requires a separate secure electrical ground connection. Individual grounding tabs are provided next to the power connectors. Similarly, the Radio Assembly chassis requires a secure ground connection. A threaded grounding binding post fitted with a knurled binding-nut is provided on the chassis next to DC input 2. Separate grounding leads with appropriate con-
nectors are supplied (either in the courtesy small-parts kit or with one end fastened to the equipment. A- For each of the power supply modules:
1. Fit one end of the grounding leads push-on connector onto the ground-
ing tab. B- For the Radio Assembly chassis:
1. Install the grounding leads lug over the binding post and firmly hand-
tighten the binding-nut. For both A and B 2. Fit the slotted connector (on the other end of each of the grounding connector) under a conveniently located screw on the rack frame or other support surface. Scrape away paint if needed to ensure clean contact. 3. Apply anti-corrosion compound where paint scraping was done. 4. Ensure by testing continuity that a se-
cure electrical and mechanical connec-
tion is achieved. If a DC rail (0V) is installed as part of the sys-
tem, the grounding leads may alternatively be fitted to the rail terminal. Caution:
Improper grounding between power supply case and rack frame may result in harmful voltage potentials and/or miscellaneous power supply switching noise problems in both receivers and transmitter. Press both red power buttons located on the front of the module to have complete power distribu-
tion to the Radio assembly. The power supply front panel LEDs indications are:
Table 1 - Power Supply LEDs Indications LED On Stby OL On & OL Color Green Red Steady Red Flashing green and red respectively Indication Power enabled *

* To remove voltage from the power supply PCB, disconnect the main power cords. For LEDs descriptions, see section 3.2.1.2 The Radio assembly is fused at the rear of the chassis:
Fuse 1 is a 32-volt MDL (slow-blow) 10A Fuse 2 is a 32-volt MDL (slow-blow) 30A 120 20170-200 7 ParagonPD Technical Manual 2.3.2 BDLCPD assembly Power The BDLCPD assembly uses a standard 120 VAC power cord. Plug this cord to the rear power outlet shown in Figure 6. To check or install a fuse:
1. Open the slide-out fuse drawer located be-
low the power connector. 2. Use a fine bladed screwdriver or a knife blade and gently pry open. 3. Hold the fuse support in one hand and with the other, lift the center plastic retainer until it releases the fuse sliding base. 4. Replace or install a 250V, 2A fuse. 5. To complete the procedure, push the sliding fuse base until it snaps under the retainer. 6. Re-insert the fuse drawer in its housing and push until it is fully seated and closed. When ready to apply power, use the ON-OFF toggle power switch adjacent to the power con-
nector.

They should be mounted according to any guidelines supplied with the antennas. For antennas placement and spacing, consult System Engineering. 2.4.2 Cabling and Connection 1- Route good quality 50-ohm double-shielded coaxial cable(s) (e.g. RG-214 or Heliax) from the selected antenna position(s) to the ParagonPD Radio assembly. 2- Terminate the RX-1 and RX-2 cable ends at the Receiver modules rear position with an N-type connector. 3- Similarly, terminate the TX cable end at the Power Amps module rear position with an N-type connector. Caution:
When terminating RF cables use brand-name crimping tools
(such as AMP, Jensen, Crimp-
Master, etc) of the correct size for the cable and type of connector used. Common pliers are NOT ac-
ceptable. 2.5 Completing the physical Installation. ParagonPD products are factory-configured to users requirements and are shipped ready to run. After new installations:
Re-check that all connections are secure on radio and BDLCPD assemblies (antennas, PC, power cords etc.) Check that fuses are inserted. Turn both BDLCPD and radio power ON. You are now ready to check for normal opera-
tion and to run the Radio Installation Software
(RIS) program for testing or trouble-shooting. Any change(s) to the settings must be done via files saved on diskette and loaded into the unit using the RIS program. 120 20170-200 8 ParagonPD Technical Manual 2.6 Checking out Normal Operation 1- Check that power is applied. 2- Check Radio assembly lights for proper op-
eration as per section 3.1.1 3- Check for proper operation of the BDLCPDs LEDs as per section 3.2.1.2. 4- Using the RIS program (described in section 4), and an in-line wattmeter, check forward
& reflected power to confirm antenna in-
stallations. 5- Using the RIS, check the RF link with a mo-
bile station that can be heard, by using the RIS Ping feature. See section 4.4.4.3 If user application and a mobile station are available, test the installation by going through a normal sequence of transmitting and receiving messages. 3. Operating Description 3.1 Radio Assembly The Radio assembly component of each Paragon product is made up of high performance synthe-
sized radio base station designed for single op-
eration. Referring to Figure 1 on page 5, the Ra-
dio Assemblys modules are commonly installed in a standard, 19-inch wide rack frame. 3.1.1 Front panels The complement of modules is identical for:

Figure 10 - Dual Power Supply rear connections Note: more power supply installation details are covered in section 2.3.1 3.1.2 Radio Assembly, rear panel Backplane PCB 3.1.2.1 Referring to Figure 3, two main backplanes are used. Their main components are:
RJ11 connector Mirrors the one on the front of the Speaker panel (series connected to both backplanes). Used for programming the Radio Assembly whenever the speaker panel has been removed. 120 20170-200 11 ParagonPD Technical Manual This feature is exclusive to the Series II model. Series I models programming is done externally via EPROMs. DB-25M plug at PL1 (one side of the Y cable on each PCB) used to supply the re-
ceive signal to the BDLCPDs single EXT.RADIO/TEST DB-25F plug. Two channel-select DIP switches (SW1 and SW2) This feature is exclusive to the Series II model. Cooling fan driver CN2 located on back-
plane connects to the horizontally-mounted fan on top of the Radio assembly and acti-
vated by BDLCs PTT signal. Coaxial relay driver not used. 3.2 BDLCPD The rack-mounted BDLCPD is housed in a steel case. It has no user serviceable parts. Units con-
figuration is stored in flash memory (EEPROM). 3.2.1 BDLCPD Front panel Referring to Figure 2, the front panel of the BDLCPD has two cutouts across its length. A- The left cutout groups the units type label and ten LED indicators:
The S3 label designates the BDLCPD as a three Serial-port model
(Ports 4 and 5 are reserved for future use) The RF group of 3 LEDs The RS-232 group of 5 LEDs A single CK LED The ALARMS group of 4 LEDs B- The right cutout groups two tactile (mem-
brane) switches (PF1 and RESET). Front Switches 3.2.1.1 Referring to Figure 11, the BDLCPD uses two membrane-type switches labeled:
RESET PF 1 These switches indicate contact by emitting a short BEEP tone when pressed. PF1 RESET Figure 11 - BDLCPD membrane switches Reset 3.2.1.1.1 Pressing Reset produces the same result as pow-
ering OFF and ON again. It restarts the micro-
processor, the peripherals and invokes the on-
board diagnostics. BDLCPDs radio modules internal flash-memories are read and their values are loaded in system SRAM CPU flash-memory. Normally, pressing Reset results in one short BEEP tone followed by all LEDs coming ON for about four seconds. Then, the LEDs flash in a ripple pattern for close to two seconds indi-
cating diagnostics are in progress. At the end of this period, all LEDs should be OFF except CK that should flash about six to eight times per second. Expect an additional two seconds delay for CK to start flashing and the UF indicator to come ON if the radio assembly is not connected or not powered (see section 3.2.1.2.4 for Alarm de-
tails). PF 1 3.2.1.1.2 PF 1 is a multi-function switch:
It clears LED error indications It initiates test transmissions It sets the function of the RS-232 LEDs 120 20170-200 12 ParagonPD Technical Manual Clearing Errors 3.2.1.1.2.1 Major and minor error LED indications remain lit on the front panel until:
The unit is RESET The unit is powered OFF and ON again PF 1 is pressed The PF 1 switch can be pressed at any time to clear an error display without affecting normal operations. Test Transmissions 3.2.1.1.2.2 To select a pattern and begin transmission, start by pressing and holding PF1. It beeps once, all five RS232 LEDs light; listen for a second beep followed by a third beep. After two seconds, the unit beeps and goes in TX Select mode with only the three rightmost RS-232 LEDs now used as selection indicators. Only release PF1 after the third beep. Following release:
Start of selection must be made within two seconds. If not, the unit will default to pat-
tern one and start test transmitting. PF1 may be pressed more than once. The number of times it is pressed determines the type of pattern that will be transmitted ac-
cording to Table 3 Each pressing of PF1 extends the two-second timer. The three rightmost RS-232 LEDs display are used to indicate TX mode selection as shown in Table 2. Table 2- TX mode selection LEDs indications TX pattern selected Binary TX mode LED indications FT LED RD LED TD LED 1 2 3 4 5 6 7 Off Off Off On On On On Off On On Off Off On On On Off On Off On Off On Once the type of transmission is selected, stop pressing PF1, allow the two-seconds timer to run down. Automatically, the BDLCPD turns its transmitter ON, sends the selected test pattern for 55 seconds and turns its transmitter OFF. The TX LED in the RF group of indicators lights in red while test transmitting. Pressing PF1 while the 55 seconds test is in progress stops the test. At the end of test transmission, BDLCPD opera-
tion returns to normal and the RX LED lights in green (monitoring normal transmitter activity). Table 3 - Test Transmissions ParagonPD 16000 b/s 25600 b/s 2400 Hz Dotting*

tion measurements. Pattern 6 produces a transmission of 55 seconds followed by 55 seconds of silence. Initial transmis-
sion in a sequence may be shorter than 55 seconds. TX LED stays steadily red for duration of the test. Press PF1 to terminate beacon mode. 3.2.1.1.2.3 RS-232 LED Function Selection The PF 1 button is used to select the RS-232 display mode as follows:
If pressed ONCE (do not hold pressed):
- Clears Alarm indications
- CK LED stops flashing for 2 seconds
- During this time, one or all of the RS-232 numbered LEDs (see Figure 13) will light. If one LED lights, it denotes the port to which the subsequent display applies. If all numbered LEDs light, it denotes that the normal 3-port display mode is active. The selected display remains active until 120 20170-200 13 ParagonPD Technical Manual manually changed or until RESET is pressed or until power up. Table 4 - RS-232 LED Function Selection Sequence RS-232 LED Function Selection Sequence ALL Radio Network Indicators 3.2.1.2.1 The Radio Network LEDs are useful when trou-
bleshooting as an indication of network activity. It can help isolate transmission problems. 1 2 3 4 (reserved) 5 (reserved) ALL 1 2 3 4 (reserved) 5 (reserved) TX LED in RF group lights with any and all transmission TX LED in RF group only lights with an ACK or DATA transmission If, during the 2 seconds period that CK is not flashing, PF 1 is pressed a second time, the LED functions will advance one step from top to bottom through the available options in the order shown in Table 4. PF 1 may be pressed repeatedly during the 2 second period (extended with each press) to advance to the desired numbered LED func-
tion option. Once the desired RS-232 LED function is se-
lected, stop pressing PF1, allow the two-seconds timer to run down. The BDLCPD returns to nor-
mal operation using the newly selected display. 3.2.1.2 LEDs and Indications LEDs are used to indicate the operation status of the BDLCPD. Although capable of displaying three colors, only the green and red colors are used for the BDLCPD. They are grouped by their function:
RF Group, displays radio channel status in green RS-232 Group, displays serial port status in green except the TX LED that also uses red ALARM Group, displays fault status in red CS RX TX CS RX TX RF Figure 12 - RF indicators Carrier Sense - Steady light indicates that an incoming radio data signal is be-
ing detected by the DSP modem. CS signal is not user-adjustable. Receive Data Flashing light indicates unit is internally receiving data from the radio network. Transmitter ON blinks green indicates
(depending on display mode selected):
That a data packet or ACK (packet acknowledgment) is being transmitted. That an idle packet, data packet or ACK is being sent. Test transmis-
sion display is done in red. RS-232 Port Indicators 3.2.1.2.2 The RS-232 LEDs normally indicate port activ-
ity on the port selected. See section 3.2.1.1.2.3 above for instructions for selecting display CM FR FT RD TD 1 3 2 RS-232 mode. Figure 13 - RS-232 Port LED indicators CM Command Mode - LED lights and re-
mains lit while the selected port is ac-
cessing the Command Processor. It lights ON and OFF while being configured. 120 20170-200 14 ParagonPD Technical Manual FR FT RD TD Flow Control on Receive - the BDLCPD has received a flow control signal from the device connected to it. When it lights, BDLCPD has stopped sending data to the DTE. When LED goes out, the port terminal is again ready to receive data. Flow Control on Transmit - the BDLCPD has sent a flow control signal to the DTE asking it to stop sending data. The LED remains lit as long as the terminal is be-
ing held off. Receive Data - when lit, it shows that the Receive Data pin 3 on the RS-232 inter-
face connector is active. Since all BDLCPD are configured as DCE, it means that the DTE is receiving data from the BDLCPD. Transmit Data - shows the status of Transmit Data pin 2 of the RS-232 inter-
face. When lit, the DTE is sending data to the BDLCPD. 3.2.1.2.3 CK Check and Power Check:
Normally flashing rapidly (about 6 cps), indicates microprocessors are working correctly and power is applied. Not flashing indicates unit is not func-
tioning. Blinking slowly (1 cps), indicates the parameters contents of the flash memory have been corrupted. The unit automati-
cally loads its set of factory default pa-
rameters and starts beeping at 20 sec-
onds intervals. May also initialization has occurred indicate DSP-modem re-
Alarm Indicators 3.2.1.2.4 All alarm conditions will cause the BDLCPD to light one or more of the LED indicators. LEDs remain ON when lit until cleared by either pressing PF 1 (without affecting operation of the unit) or RESET (cycling unit OFF and ON). LM RM LF UF ALARMS Figure 14 - ALARMS LED indicators LM Local Minor Alarm - when lit, indicates the presence of any of the following mi-
nor faults:
- Parity, framing or overrun error at any RS-232 port.
- Out of buffers. No memory available to accept data from a local terminal de-
vice. Usually denotes a flow control problem.
- Flash memory error. At power-up or reset, the unit detected a change in non-
volatile memory. RM Remote Minor Alarm - when lit, indi-
cates any of the Local Minor Alarm listed above have taken place at the re-
mote end of the link (i.e. the mobile the local base station is currently communi-
cating with). It will also light when a protocol error has been detected on the network. In a network using the Host Link Ac-
tive (MSC) feature, the RM LED, flashing in-sync with the CK LED, indi-
cates that the link is down. 120 20170-200 15 ParagonPD Technical Manual LF UF Link Failure - when lit, indicates that the base station fails to receive an ACK for a packet sent and for all subsequent re-
tries. Some data has possibly been lost. LF is not functional if all active ports are set to NAR mode. Link fails are inevitable during normal operation (mobiles temporarily out of range, in a tunnel, parked in a dead spot, etc.). A lit LF LED is not normally cause for concern. Unit Failure - when lit, the unit requires attention:
- the BDLCPD is not operable;
It may indicate detection of a system software error trap.
- the BDLCPD is operable;
Indicates that on power-up, invalid data was detected in the serial EEPROM chip
(located in the radio modules). It may also indicate that connection to the radio modules is incorrect or that radio power is not applied. The LM, RM and UF alarms also sound a beep when a fault occurs. The LF alarm is silent. 3.2.2 BDLCPD Rear panel Referring to Figure 4, the rear panel of the BDLCPD has the following set of chassis con-
nectors:

Check and troubleshoot ParagonPD. Save an existing configuration. Upload files for field configuring of units
(Requires intervention with technical sup-
port). Important note:
The aggregate total baud rate for all active ports on a BDLCPD must not exceed 30,000 for ParagonPD. Sustained simultaneous op-
eration on devices 1 and 3, using the fac-
tory settings for these ports, may result in lost characters. Using the factory settings, device 3 is in-
tended only for use during configuration and should not be used simultaneously with data traffic on device 1. For special user applica-
tion done while the BDLCPD is active, use either device 2, or set device 3 to 2400 bauds. 120 20170-200 17 ParagonPD Technical Manual To run the program, you will need:
- A PC or portable computer with a 486 class CPU or better. 2 free megabytes of RAM.
- A hard disk.
- An available COM port.
- A serial mouse, with its own driver installed is strongly recommend however most actions can also be done using keyboard commands. ParagonPD and Paragon products share the RIS program with the MobilPac family of products. It is available on diskette, Dataradio p/n 085 03355-00n. Please refer to the readme.txt file included on the diskette for installation instructions. 4.1 Operation This support program is DOS-based and can be run in MS-Windows MS-DOS mode.

Subsequently restore the configuration. Safeguard a copy as documentation of the configuration. Note: The configuration and status files are ASCII files and may be e-mailed or faxed to technical support when requested to do so. Warning: Do NOT make any change to these files unless called for in the trouble-shooting section of this manual or by Dataradios System Engineering or Technical Support departments. Changing unknown parameters may render unit inoperative. 120 20170-200 19 ParagonPD Technical Manual Connect using COM1 9600 OK Cancel Figure 17 - Connect using dialog window Connect Button 4.4.1.1 The Connect button is used to establish the re-
quired communication link with the connected ParagonPD unit. 1. Press the Connect button to open the Con-
nect using dialog window (see above). 2. Select the appropriate COM port where the ParagonPDs RS-232 cable is connected on your PC or portable computer and the port speed (usually 19200) for the COM port selected. This speed is independent of the network bit rate. Bit rates from 2400 to 19200 are supported. 3. Click OK. This validates the options entered and starts the connection sequence. The program briefly displays pop-up window messages as it establishes a communications link with the equipment. Their content is not normally user-sensitive and only denotes proper operation. If an Error window opens, check the connections and that the right options were selected in the Connect using dialog window. Selecting an incorrect port speed in the Connect using window will result in the status bar re-
porting Connection failed!
When communication linking is complete:
The Status bar reports Connection estab-
lished. All of the buttons grayed-out at startup be-
come available. The Comment and Password fields and their respective Put buttons are activated. The product field indicates the product model connected to. The Banner information is displayed. Get button 4.4.1.2 After communication is established using the Connect button, press the Get button to down-
load and automatically save the connected BDLCPD configuration setting to a file named with the unit's on-air address (as set at the time of manufacture). The RIS status bar will then report All parameters are successfully re-
trieved and saved in file [unit's on-air ad-
dress].bp2. Any previous configuration in the program is overwritten. If you do not wish to overwrite an existing con-
figuration or prefer to name the file yourself, use the Get As button. Example: In a network using multiple BDLCPD having a common address, using the Get As button allows to uniquely name the files. Get As button 4.4.1.3 After communication is established using the Connect button, press the Get As button to:
Open the File, Save As window with the ASCII file *.bp2 (already selected). Save the connected BDLCPDs operating characteristics (configuration setting) to a file, directory or drive of your choice. The program will ask before overwriting an existing file. Status bar reports All parameters are suc-
cessfully retrieved and saved in [filename]. 120 20170-200 20 ParagonPD Technical Manual 4.4.2 Configuration from a File Loading a configuration from a file to a BDLCPD is useful to:
Restore the operating characteristics of a unit (Requires intervention with technical support.) Carry out field updates using Dataradio system engineering supplied diskette(s). Warning: Do NOT make any change to these files unless called for in the trouble-shooting section of this manual or by Dataradios System Engineering or Technical Support departments. Changing unknown parameters may render unit inoperative. Put From button 4.4.2.1 After communication linking is established using the Connect button:
1- Press the Put From button on the button bar. The program selects the bt2 filter file. 2- In the opened File, Put From window, lo-
cate the drive, directory and file name of the relevant file. This may be a configuration saved ear-
lier from a unit. It can also be from a Dataradio (factory or system engineering) diskette. 4- Select the appropriate file 5- Press the OK button. The status bar re-
ports: [filename] is downloading into unit and up to 30 seconds later displays: All pa-
rameters are saved. Apply Station Reset to take effect!. 6- Press the Station Reset button (unit will beep). See the next paragraph for details. Station Reset button 4.4.2.2 Press the Station Reset button as a last step after doing a Put From. This action has the same effect as when pressing the membrane switch Reset (see section 3.2.1.1.1 on page 12 for details). Causes downloaded parameters from a file or diskette to take effect in the connected unit. Pressing Station Reset is not required after doing any Comments or Password configuration change as these have their own Put Comments and Put Password buttons. Station Reset does not break the connection. 4.4.3 Special Functions The following RIS fields and buttons are used to gather specific information concerning the con-
nected BDLCPD:
Banner field Comments field and Put Comments button Password and Put Password button i button Banner Field and i button 4.4.3.1 This field displays a string made up of the serial number of the connected unit followed by the firmware(s) used and their version number. Format For ParagonPD model is:

scription(s) location, etc).
(customer name, 2- Press the button Put Comments to make the entry permanent. This field may be left blank. On subsequent Connect, this field displays en-
tered comments. If no comment was entered, the field will remain blank. Password 4.4.3.3 The password feature is useful where two (or more) fleets share the same radio channel. Mo-
biles without the proper password would still receive the message but the contents would not be intelligible. 1- Type your password directly in the Pass-
word field. It is a string of 32 hexadecimal characters (exactly). 2- Press the button Put Password to make the entry permanent. This field may be left blank. On subsequent Connect, this field will require that the correct password be entered. If none was entered, the field will remain blank. Password information is NOT retrieved and saved to a file, along with the configuration. Clearing a Password is done by entering 32 zeros. The Dataradio supplied password algorithm is designed to thwart the casual observer only. It provides a limited form of data privacy. There-
fore, if your security requirements are high, Da-
taradio urges you to use external encryption technology such as Data Encryption Standard
(DES) in the Host and Mobiles computers. 4.4.4 Test Functions The following RIS functions and buttons are used to carry out testing or trouble-shooting on a connected unit:
TXON (Modulated) button TXON (Unmodulated) button Flatness test button Random data test button Ping Address and Ping button Note:
While a button is in-use for test trans-
missions, all others are inoperative. Channel Selection 4.4.4.1 ParagonPD uses its default radio channel. No channel selection being available, all channels are grayed-out. 4.4.4.2 TXON Tests Unmodulated Carrier 4.4.4.2.1 Unmodulated carrier gives a clear carrier and is frequently used for checking:
Frequency error Forward and reflected power Press the TXON (Unmodulated) button to trans-
mit an unmodulated test signal for 30 seconds on its default channel or until pressed again. The time remaining to test transmit is displayed on the status bar. Modulated Carrier 4.4.4.2.2 Test transmission generates a carrier modulated with a test tone at a speed and a deviation level that depends on network speed as detailed in Table 8 below. 120 20170-200 22 ParagonPD Technical Manual Table 8 - Typical Carrier Modulation 4.4.4.4 Ping addresses Carrier Modulation Full Channel Network Speed Typical deviation in kHz

gin transmitting a modulated test signal for 30 seconds or until pressed again. The time remaining to test transmit is dis-
played on the status bar. Ping Button 4.4.4.3 The Ping function checks connectivity by testing the ability of ParagonPD to communicate with a mobile unit by sending a short transmission query and receiving a confirming response. 1- Specify the ping address (section 4.4.4.4) 2- Press the Ping button to start ping testing. The time remaining to test transmit is dis-
played on the status bar. 3- The program sends a test query and contin-
ues transmitting pings at brief intervals. As soon as a Ping test signal is returned from the address selected, the status bar displays:
Ping Successful and pinging stops. If no ping signal is received after 60 sec-
onds, ping testing stops and the status bar displays Ping Failed. Addresses may be entered by typing directly in the Ping Address field as an Alpha-Mapped-
Nibble (AMN) address for mobiles, consisting of upper case letters in the range A-P. The valid address range is A to GN (8 characters max.). The program may display one of the following messages on the status bar:
Ping address is not in AMN or number format or Ping address is not in the range A GN In either case, check that the address entered is within the acceptable range, is of a valid format and correctly typed. Flatness test button 4.4.4.5 This complimentary feature has been added to support the ParagonPD radios low-frequency balance adjustment. Tests generate a square wave at a frequency of 100 Hz. Press the Flatness test button to transmit a square wave test signal for 30 seconds or until pressed again. The time remaining to test transmit is displayed on the status bar. Random data test 4.4.4.6 Random data test transmissions are used for checking low-frequency balance. Refer to Table 10, at the Low Frequency Balance (step 7). Random data test requires the use of an IFR COM-120B service monitor with option 03:

a) Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R output and the receiver antenna connector. b) Select the generator mode (GEN button) and set to the main receiver channel frequency c) Select and turnon GEN2 d) Set the FM Deviation to 3kHz (full channel) or 1.5kHz (half channel) using 1 kHz sine e) Select SINAD meter 2) Monitor the SINAD by connecting an X1 scope probe to the Demod O/P test point (close to PL103 in the first section from the module front panel) or on the relevant backplane board at SK1 pin 6 (see Figure 30 for test point location). 3) Adjust the helical resonators #H1 to #H3 for best SINAD. 4) Continually decrease the RF level to reach 12dB SINAD, then re-do steps 3) and 4) again. (mini-
mum requirement to reach is 12 dB SINAD for 110 dBm) 5) Perform the SINAD linearity tests described in the next paragraphs below. If it fails to pass the requirement, contact your Dataradio technical support. 120 20170-200 33 ParagonPD Technical Manual WARNING: Do not attempt to re-tune the IF stages (i.e. L312 to L318). These adjustments do not need to be re-adjusted after frequency re-programming. Touching these coils will have a direct impact on the DSP modem coefficient settings and may significantly reduce the radio performances over data. 6.2.2.4 SINAD and Linearity Check 1. Apply the following settings to the IFR:
- Generator mode, Output T/R
IFR TX frequency to match the main radio RX frequency Filter set to wide band (no audio filter) Select Gen2 (Modulating tone fixed to 1KHz). All other Gen must be off, except for wide-
band. Set deviation to 3.0KHz for full channel or 1.5KHz for half channel radios.
2. Lower the RF level to get a 12dB SINAD reading. Level must be better than -110dBm (including cable loss). 3. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) above the main radio RX frequency, record the SINAD reading. It should remain within 1.5dB from the on frequency SINAD reading. 4. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) below the main radio RX frequency, record the SINAD reading. It should remain within 1.5dB from the on-frequency SINAD reading. Note:
If one of the above requirements is not met, try to re-tune the front-end. If it is still failed, contact your Dataradio technical support. 6.2.2.5 Note: This check is only recommended for ParagonPD model running DBA protocol 3.06.009 series or RSSI Adjustment later. 1. Apply an on-channel signal from the RF generator at a level of -110dBm with deviation of 3kHz
(full channel) or 1.5kHz (half channel) at 1kHz tone. 2. Adjust RV301 (RSSI level) to give 2.0V RSSI output when measured with a multimeter at SK301 pin 2 or on the relevant backplane board at SK1 pin 5 (see Figure 30 for test point location). 3. Vary the RF level in 10dB steps and check that the RSSI output voltage changes at a rate of a 10dB/V (0.20VDC) over the range of 120dBm to 80dBm. If the requirement cannot be reached, contact your Dataradio technical support. 120 20170-200 34 ParagonPD Technical Manual 6.2.3 Exciter Module (T881) Note 1: Refer to Figure 22 on page 39 for locating tuning controls. Note 2: When the synthesizer is unlocked, the front panel green LED called "Supply" will be flashing showing that it needs to be re-tuned. 6.2.3.1 Initial Setup 1. Shut down power to the base station 2. Prepare the multimeter to read DC Volts. 3. Remove the exciter (T881) module from the base station rack frame 4. Remove the exciter top cover (nearest the handle). 5. Connect the ParagonPD Extender Rail kit between the exciter module and the empty chassis exciter slot. 6. Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R output and the exciter antenna connector. 7. Apply power to the base station 6.2.3.2 Synthesizer Alignment Single channel: Connect the multimeter to the long lead of L1 in the VCO (this measures the syn-
thesizer loop voltage). Tune VCO trimmer C6 for a synthesizer loop voltage of 7VDC. Multiple channels: Adjust the VCO loop to 7V using the middle frequency channel. All channels should lie within the upper and lower limits of 10V and 3V respectively. Note: Normally, the fast TX key option is installed and the synthesizer is always energized. Where that option was not fitted, key the transmitter by pressing the front panel Carrier button to make the above adjustment possible. 6.2.3.3 TX Frequency Error Adjustment 1.

Transmit a square wave by pressing the BDLCPDs PF1 button and following the procedure outlined in section 3.2.1.1.2.2 or run on another computer the RIS program and press the Flatness test button. Record deviation again. 6. The difference in deviation between the two channels should be less than 300 Hz. If not, re-
adjust RV105 to "average" the square wave shape on both channels until the spec is met. 7. To confirm the adjustment, select the active, or the lowest frequency channel. Compare the devia-
tion produced between:
- TX ON (Modulated) and
- Random data tests, The difference should be lower than 300 Hz. For multi-channel unit, repeat this step on the highest frequency channel. 8. Select the active channel. Transmit a TX ON (Modulated) adjustment tone by pressing the BDLCPDs PF1 button and following the procedure outlined in section 3.2.1.1.2.2 or run on an-
other computer the RIS program and press the TX ON (Modulated) button. Make sure that devia-
tion level read on the IFR correspond to model and bit rate in use (see Table 8 - Typical Carrier Modulation). Re-adjust deviation as necessary referring to Checklist B - page 26. 6.2.3.5 Exciter Power Output 1. Apply the following settings to the IFR:

- Connect the coaxial cable from the IFR T/R to the Exciter output connector 2. Key the Exciter by pressing the module PTT button. The output power must be:
800 MHz (T881) = 5W 300mW. 3. If 5Watts is not reached, adjust helical #L300 for maximum power output (which should be at least 7W); adjust RV356 down to 5W. 120 20170-200 36 ParagonPD Technical Manual 6.2.4 Power Amplifier Module (T889) 1. Re-install the exciter module into the Paragon rack frame 2. Connect the Exciter module to the Power Amplifier 3. Connect the Power Amplifier output to the IFR T/R connector or to a stand-alone BIRD style power meter, terminated with a 150W dummy load. 6.2.4.1 Power Amplifier Power Out 1. Set RV63 (Power adjustment, access on the front panel) fully clockwise. 2. Key the transmitter from the exciter Carrier button. The power output should exceed 90W. 3. Adjust RV69 (Driver power, access from the left end side) until the output power drops to 90W. 4. Adjust RV63 (Power) to reduce power output to its nominal value (70W) or lower as required. 5. Cable loss should be included in the reading. 6.2.4.2 Forward Power Alarm Level 1. Power up the T889 and adjust RV63 (Power) so that the output power is at the alarm level re-
quired, usually 20% lower than nominal value (e.g. 40W if the PA normally operates at 50W). 2. Adjust RV48 (Forward power Alarm set) so that the forward power alarm LED lights. 3. Adjust RV63 (Power) for the normal operating power level. 6.2.4.3 Reverse Power Alarm Level (Optional) 1. Power up the T889 and adjust RV63 (Power) for the normal operating power level. 2. Place a known mismatch of the required value (e.g. 3:1 VSWR) and adjust RV52 (reverse power alarm set) so that the reverse power alarm LED lights. Example: A VSWR of 3:1 can be simulated by connecting an undetermined 3 dB pad to the PA output. This will result in a loss of 6 dB. 120 20170-200 37 ParagonPD Technical Manual FRONT PL103 Demod output RSSI Test point:

- PGM800Win Windows based programming software
- T800-01-0002 programming cable (DB-25 to RJ-45 cable)
- Standard 25-pin parallel cable (terminated Male/Female) 120 20170-200 40 ParagonPD Technical Manual 6.3.2 Module Programming Before starting programming, have a PC running MS-Windows and the Tait PGM800Win soft-
ware for Series II Base station. This program supports the use of a mouse but may be used without one if required. Keyboard access follows the conventional MS-Windows method as briefly described below:
- Press and hold the Alt key while pressing at the same time the relevant hotkey as indicated by an underlined letter on the menu command.
- On a drop-down menu, press only the hotkey without pressing the Alt key.
- Use the Tab key to cycle available fields and the Enter key to validate entries. E.g. Pressing Alt+F opens the File drop-down menu and pressing A opens the Save As di-
rectory service box. Receiver VCO and front-end alignment will be required when new receiver frequency is pro-
grammed outside the radio tuning range:
UHF = 2.5 MHz from previous center frequency. VHF = 1.5 MHz from previous center frequency. Exciter and PA alignment will be required when new transmitter frequency is programmed outside the radio tuning range:
VHF & UHF= 4 MHz from previous center frequency. 1. Connect the PC, via the supplied programming lead, to the speaker panels front-mounted RJ11 connector. 2. Run Tait PGM800Win program and follow instructions found in the T800 Programming Soft-
ware Users Manual to select the proper module to be programmed. 3. Program required channel's frequencies. Do not program any CTCSS tones on channels. Do not change any other parameters. Refer to Figure 23, Figure 24, Figure 25 and Figure 26 for screen program examples. 4.

To set a default channel via the software, all DIP switches must be set to OFF (i.e. 00000000). When a switch is Off, its binary count is active; when a switch is ON its binary count is inac-
tive. The various DIP switch combinations of ON or OFF make up a binary total, which identifies the channel number. To select a channel, set the appropriate DIP switch or switches to OFF to make the binary count total the channel number you want. Set all other switches to ON. It is recommended to set both SW1 (RX) and SW2 (TX) to the same settings. Example: To select channel 5, set the DIP switches as shown in below:

Place a known mismatch of the required value (e.g. 3:1 VSWR) and adjust the reverse power alarm set (T859: RV52 or T839: RV105) so that the reverse power alarm LED lights. Example:
A VSWR of 3:1 can be simulated by connecting an unterminated 3dB pad to the PA output. This will result in a return loss of 6dB. 120 20170-200 51 ParagonPD Technical Manual 6.4.4.4 Tait T859 (UHF) Standard Tuning Procedure 1. For sets with serial numbers following 217262, set RV69 (driver power level) fully clockwise. 2. For all units, preset the tuning controls as shown in Figure 31 Figure 31 - T859 Tuning Settings 3. Set RV63 (front panel power control) fully clockwise. 4. Key on the exciter (press PTT button). 5. Adjust CV1 for maximum output. 6. Adjust CV8 for maximum output. 7. Adjust CV32 for maximum output. 8. Adjust CV51 and CV57 for maximum output. 9. Adjust CV34 and CV35 for maximum output. 10. Recheck all settings. The power output should exceed 110W. 11. For sets with serial numbers following 217262, adjust RV69 (driver power level) until the output power drops to 110W. 12. For all units, adjust RV63 to reduce the power output to the required level (normally 100W). 6.4.4.5 Tait T859 Tuning for Best Efficiency 1. Insert a Shunt current device (HP 34330A Shunt 30A ) between the power supply red wire and its 13.8Vdc output, then connect the shunt to the multimeter (VDC scale) 2. While transmitting, monitor the current. It should remain under 22A. 3. Retune CV32, CV51 and CV57 towards maximum capacitance to obtain minimum supply current, but do not exceed a maximum drop of 0.5A per control. 4. Check that the supply current is <22A for 100W output power. Note:
These control settings are normally very close to minimum supply current. If the cur-
rent is reduced too far, maximum power output will drop and 2f rejection may degrade. 120 20170-200 52 ParagonPD Technical Manual IC 310 SK330 pin 2 Figure 32 - T855 Receiver Tuning Controls Location 120 20170-200 53 ParagonPD Technical Manual TCXO Figure 33 - T857 Exciter Tuning Controls Locations 120 20170-200 54 ParagonPD Technical Manual L410 L420 L1 L460 L47 L330 CV318 L340 RSSI Test Point P207 IC 700 CV1 L350 IC 350 L360 Figure 34 - T835 Receiver Tuning Controls Location 120 20170-200 55 ParagonPD Technical Manual IC700 TCXO L1 CV1 IC220 Figure 35 - T837 Exciter Tuning Controls Location 120 20170-200 56 ParagonPD Technical Manual Appendix 1 - ParagonPD Deviation adjust 1. Using the RIS, press TX ON (Modulated) and record deviation level as read on the IFR. 2. Using Windows Notepad, Edit the .bp2 file named with the corresponding BDLCPD serial number (e.g. abcd.bp1). Save as to another file name and keep it in case something goes wrong while changing a parameter. 3. Locate the line labeled Dev0 Par85= and record the value beside the = sign. This is the corresponding parameter value to the deviation read in step 1. 4. Apply the following formula to determine the new parameter value to be set:
(New Par85 value) = [(initial Par85 value) X (target deviation) / (deviation read)] + 2 5. Change the value in the file, Save as using the BDLCPD serial number file name. 6. Run the RIS again and do a Put From. From the opened window, select the file that you just made the change to and then press OK 7. Again, check deviation level while pressing TX ON (Modulated). If fine-tuning of Par90 value is still required, Edit the file again and re-do step 5 by changing directly the Par85 value by 1 or 2 up or down. 8. Re-check deviation level. If the level is now correct, press Stationreset to make the change permanent. 120 20170-200 57 ParagonPD Technical Manual 7.

Third Party Power Supply 13.8VDC Nominal 120 20190-001 7 Paragon-III Technical Manual 2.5 Electrical Standard 120 VAC electrical power is required. It should be capable of providing at least 10A to power Paragon-III (<6A) and ancillary equipment. 2.5.1 Paragon-III Assembly Power Two distinct power configurations (rear views) are shown in the preceding pages. They are:
Paragon-III Base Station Standard Assy. This configuration is described in paragraph 2.5.1.1 below. Paragon-III Base Station Assy. with 3rd party DC supply (Figure 4). Refer to Dataradio System Engineering for further details. 2.5.1.1 Standard Power Supply Configuration The Radio assembly unit receives two separate 13.8 VDC power inputs from a T800 Slimline dual power supply typically rack-mounted right below the main assembly radio chassis. The T800 is made up of two separate power supply units joined in a single chassis:
A T807 using convection cooling is rated to 15A nominal at 13.8VDC. It supplies all the radio modules other than the Power Amplifier. A T808 using convection and fan cooling is rated to 25A nominal at 13.8VDC. It supplies only the Power Amplifier module (T859, or T889). Normally used at room ambient temperatures, they can operate within their specifications over a range of 10 to +60 C. Note: Internal over-temperature protection shuts down the main transformer above 105 degrees Cel-
sius. Both power supply modules are internally connected to ground via their individual, rear-connected, seven-foot standard 120 VAC power cords. Nevertheless, each requires a separate secure electrical ground connection. Individual grounding tabs are provided next to the power connectors. Similarly, the Radio Assembly chassis requires a secure ground connection. A threaded grounding binding post fitted with a knurled binding-nut is provided on the chassis next to DC input 2. Separate grounding leads with appropriate connectors are supplied (either in the courtesy small-parts kit or with one end fastened to the equipment. For each of the power supply modules, fit one end of the grounding leads push-on connector onto the grounding tab. For the Radio Assembly chassis, install the grounding leads lug over the binding post and firmly hand-tighten the binding-nut. For both T807 and T808 power supply modules 1. Fit the slotted connector (on the other end of each of the grounding connector) under a conveniently located screw on the rack frame or other support surface. Scrape away paint if needed to ensure clean contact. 2. Apply anti-corrosion compound where paint scraping was done. 3. Ensure by testing continuity that a secure electrical and mechanical connection is achieved. If a DC rail (0V) is installed as part of the system, the grounding leads may alternatively be fit-
ted to the rail terminal. Caution:
Improper grounding between power supply case and rack frame may result in harmful voltage po-
tentials and/or miscellaneous power supply switching noise problems in both receivers and trans-
mitter. 120 20190-001 8 Paragon-III Technical Manual 2.5.1.1.1 T808/807 DC Power Supply Connection & Torque Settings Warning:
Securing the DC Power Supply cable into the DC connector to provide a good electrical connection is essential. Over time, the wires tend to compress in the DC connector re-
sulting in an increasingly poorer connection. Consequently, as high current is drawn, the connector heats up increasing the resistance thereby causing still more heat until the connector eventually burns up. Although screws securing DC cables to the Power Supply terminals are tightened to the torque set-
tings given below prior to new system delivery, they must be re-tightened as part of the commis-
sioning process and re-tightening is also part of the regular maintenance schedule. Prior to replacing a Power Supply module into an existing system, inspect the cable and re-terminate the DC wires if the strands have previously been twisted together or show any sign of damage. Cut the wire at the end of the insulation and then strip approximately .4 inch (10mm) of insula-
tion off the cable. DO NOT TWIST THE WIRE STRANDS. Insert the DC cable into the screw terminal and tighten the screw to secure the cable as per the torque settings given below. Torque Settings:
The manufacturer recommends torque setting all power supply terminal screws to:
0.5 to 0.6 Nm (or 4.5 to 5.3 In/lb or to .37 to .44 ft/lb) Note: Dataradio uses a Sturtuvan Richmond 29-pieces adjustable torque screwdriver model CAL36/4K. After tightening, pull on the cable to check the cable is secured tightly into the screw terminal. 2.5.1.1.2 Power Indications Press both red power buttons located on the front of the module to have complete power distri-
bution to the Radio assembly. The power supply front panel LEDs indications are:

They should be mounted according to any guidelines supplied with the antennas. For antennas placement and spacing, consult System Engineering. 2.6.2 Cabling and Connection 1- Route good quality 50-ohm double-shielded coaxial cable(s) (e.g. RG-214 or Heliax) from the selected antenna position(s) to the Paragon-III Radio assembly. 2- Terminate the RX-1 and RX-2 cable-ends at the Receiver modules rear position with an N-type connector. 3- Similarly, terminate the TX cable-end at the Power Amps module rear position with an N-type connector. Caution:
When terminating RF cables use brand-name crimping tools (such as AMP, Jensen, Crimp-Master, etc) of the correct size for the cable and type of connector used. Common pliers are NOT acceptable. 2.7 Completing the physical Installation. Paragon-III products are factory-configured to users requirements and are shipped ready to run. After new installations:
Re-check that all connections are secure on the radio-BDLC assemblies (antennas, PC, power cords etc.) Check that fuses are inserted. Turn both BDLC-III and radio power ON. You are now ready to check for normal operation (as per paragraph 2.8) and to run the Dataradio CDip program for testing or trouble-shooting. Any change(s) to the settings must be done via files saved on diskette and loaded into the unit using the CDip program. 2.8 Checking out Normal Operation 1- Check that power is applied. 2- Check Radio assembly lights for proper operation as per section 3.1.1 3- Check for proper operation of the BDLC-IIIs LEDs. 4- Using the CDip program and an in-line wattmeter, check forward & reverse power to confirm main antenna installation 5- Using CDip, check the RF Data Link with a mobile that can be heard (as per section 4.3.1) If user application and mobiles are available, test the installation by going through a normal sequence of transmitting and receiving messages. 120 20190-001 10 Paragon-III Technical Manual 3. Operating Description 3.1 Radio Assembly The Radio assembly component of each Paragon product is made up of high performance synthesized radio base station designed for single operation. The Radio Assemblys modules are commonly installed in a standard, 19-inch wide rack frame. The complement of modules is identical for Series II UHF, and 800 MHz models:
2 x Receivers 1 x Exciter 1 x BDLC-III (controller-modem) 1 x Power Amplifier 1 x Speaker panel 1 x Dual Power Supply 3.1.1 Receiver module The RX1 and RX2 receivers use identical front panel controls and indicators. These are:
Gating Sensitivity - sets the RF signal level required to open the mute gate and allow audio to pass to the speaker1. Gate LED - indicates the status of the mute circuit. It is lit when a signal above the mute threshold is received1. Supply LED - is lit when DC power is applied. Fast Flashes when linked with PGM800Win. Slow Flashes indicates VCO
(synthesizer) out of lock. Unequal Flashes indicates internal communication error. Line Level - Not used Monitor Volume - The audio output delivers up to 1 watt to the speaker. Always set volume knob to minimum when not in use to reduce current consumption. Monitor Mute Switch - opens the mute, allowing continuous monitoring of the audio signal. On = audio muted Receiver Gating Sensitivity Gate Line Level Supply Monitor Volume Off On Monitor Mute Gating Sensitivity Gate LED Line Level Monitor Volume Monitor Mute On - Off 1 Gating Sensitivity and Gate LED are not functionally used except to allow listening to incoming receptions as a trouble-shooting aid. Depending on the sensitivity adjustment, the Gate LED lights and a relay can be heard on incoming RF signals.

1- Specify the address:
Addresses may be entered by typing directly in the Address field in two ways:
- Numerically, the valid address range is 1-126.
- As an Alpha-Mapped-Nibble (AMN) address, consisting of upper case letters in the range A-P. The valid address range is A to GN.
- The base address is usually: 1.
- The program may display one of the following messages on the status bar:
- For Paragon-III products:
address is not in AMN or number format
- For mobile products:
address is not in the range A GN In either case, check that the address entered is within the acceptable range, is of a valid format and correctly typed. 2- Enter the Device number for mobile (or base station). 3- Press the Send button. The Chat window reports Sent to xx mobile (where xx is mobile name). If test is successful:
Status line reports Delivery confirmed. If test unsuccessful:
Chat window reports Waiting, Then the Status line reports Delivery Failed. 120 20190-001 21 Paragon-III Technical Manual 5. Radio Programming and Adjustments All receiver procedures detailed in this section should be done twice: once for the Main (or RX1) receiver module and a second time for the Auxiliary (or RX2) receiver module. Connect to the relevant module and its corresponding backplane PCB as required. 5.1 This procedure describes the steps needed to program the Paragon-III radio base station UHF, and 800 MHz (half & full channels). Series II Radio Programming Recommended Items 486 PC or better, MS-Windows 98 or later 5.1.1
- T800win programming kit for Series II:
- PGM800Win programming software user's manual
- PGM800Win Windows based programming software version 3.0 or later
- T800-01-0002 programming cable (DB-25 to RJ-45 cable)
- Standard 25-pin parallel cable (terminated Male/Female) Module Programming 5.1.2 Before starting programming, have a PC running MS-Windows and the Tait PGM800Win soft-
ware for Series II Base station. This program supports the use of a mouse but may be used without one if required. Keyboard access follows the conventional MS-Windows method as briefly described below:
- Press and hold the Alt key while pressing at the same time the relevant hotkey as indicated by an underlined letter on the menu command.
- On a drop-down menu, press only the hotkey without pressing the Alt key.
- Use the Tab key to cycle available fields and the Enter key to validate entries. E.g. Pressing Alt+F opens the File drop-down menu and pressing A opens the Save As directory service box. Receiver VCO and front-end alignment will be required when new receiver frequency is pro-
grammed outside the radio tuning range:
800 = 3.0 MHz from previous center frequency UHF = 2.5 MHz from previous center frequency. Exciter and PA alignment will be required when new transmitter frequency is programmed out-
side the radio tuning range: 4 MHz from previous center frequency. 1. Connect the PC, via the supplied programming lead, to the speaker panels front-mounted RJ11 connector. 2. Run Tait PGM800Win program and follow instructions found in the T800 Programming Software Users Manual to select the proper module to be programmed. 3. Program required channel's frequencies. Do not program any CTCSS tones on channels. Do not change any other parameters. Refer to Figure 13, Figure 14, Figure for screen program examples. 4. Save the base station programming info to a file for further reference. 120 20190-001 22 Paragon-III Technical Manual Figure 13 - Receiver System Information Sample Figure 14 - Receiver Channel Information Sample 120 20190-001 23 Paragon-III Technical Manual Figure 15 - Exciter System Infomation Sample Figure 16 - Exciter Channel Information Sample 120 20190-001 24 Paragon-III Technical Manual 5.1.3 Channel Selection via DIP Switches The backplane-mounted DIP switch settings override the default channel programmed by PGM800Win. To set a default channel via the software, all DIP switches must be set to OFF (i.e. 00000000). When a switch is Off, its binary count is active; when a switch is ON its binary count is inactive. The various DIP switch combinations of ON or OFF make up a binary total, which identifies the channel number. To select a channel, set the appropriate DIP switch or switches to OFF to make the binary count total the channel number you want. Set all other switches to ON. Example: To select channel 1, set the DIP switches as shown below:
Binary Value 1 2 4 8 16 32 64 Always ON except when default channel is required O F F 1 2 3 4 5 6 7 8 X R

a) Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R output and the receiver antenna connector. b) Select the generator mode (GEN button) and set to the main receiver channel frequency c) Select and turn-on GEN2 d) Set the FM Deviation to 3kHz (full channel) or 1.5kHz (half channel) using 1KHz sine e) Select SINAD meter f) Use a X1 scope probe connected to SINAD input and monitor the Discriminator O/P on the back-
plane at SK1 pin 6 (RX-audio1). Alternately, it is also possible to monitor at the receiver I/O Pad P207 (T885), the receiver TP314 (T855). 2. Adjust the helical resonators for best SINAD: #H400, #H401 and #H900 (T885); #FL410 and #FL420
(T855). 3. Continually decrease the RF level to reach 12dB SINAD, then re-do step 2) & 3) again. The absolute minimum requirement level to reach is -108dBm (typical level is -109 to -110 dBm) 4. Perform the SINAD linearity tests described in paragraph 5.2.2.4. If it fails to pass the requirement, contact your Dataradio technical support. WARNING: Do NOT attempt to re-tune the IF stages
(I.e. L300 and L301 for T885, L310 to L390 for T855 or L330 to L360). These adjustments do not need to be re-adjusted after frequency re-programming. Touching these coils will have a direct impact on the modem DSP ISI coefficient settings and may reduce signifi-
cantly the radio performances over data. 120 20190-001 27 Paragon-III Technical Manual 5.2.2.4 SINAD and Linearity Check 1. Apply the following settings to the IFR COM-120:
a) Generator mode, Output T/R, TX frequency to match the main radio RX frequency b) Filter set to wide band (no audio filter) c) Select Gen2 (Modulating tone fixed to 1KHz). All other Gen must be off. d) Set deviation to 3.0KHz for full channel or 1.5KHz for half channel radios. e) Use a X1 scope probe connected to the IFR SINAD input and monitor the Discriminator O/P on the radio backplane at SK1 pin 6 (RX-audio1). Alternately, it is also possible to monitor at the receiver I/O Pad P207 (T885), the receiver TP314 (T855). 2. Lower the RF level to get a 12dB SINAD reading. Level should be better than -108dBm (including ca-
ble loss). 3. Offset the IFR TX frequency 2kHz (full channel) or 1kHz (half / NPSPAC channel) above the main radio RX frequency, record the SINAD reading. It should remain within 1.5 dB from the on frequency SINAD reading. For T885 and T855, use above values. 4. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half / NPSPAC channel) below the main radio RX frequency, record the SINAD reading. It should remain within 1.5 dB from the on-frequency SINAD reading. For T885 and T855, use above values. Note: If one of the above requirements is not met, try to re-tune the front-end. If still failed, contact your Dataradio technical support. 120 20190-001 28 Paragon-III Technical Manual 5.2.2.5 RSSI Adjustment
- Caution: mis-adjusting RSSI may reduce the Paragon-III's Parallel Decode (PD) performance.
- BDLC-III must be connected to the radio chassis assembly during this process. 1. T885-xx-0200 (800 MHz) and T855-xx-0250 (UHF) receivers:
Refer to Figure 20 - T885-0200 Receiver Tuning Controls location or
- Figure 22 - T855 Receiver Tuning Controls location
- Apply an on-channel signal from the RF generator at a level of -110 dBm modulated by a 1 kHz tone at a deviation of 3kHz (full channel) or 1.5kHz (half / NPSPAC channel).
- Adjust RV 345 (RSSI level) for T885, RV320 (RSSI level) for T855 to give 2.0V RSSI output at SK330 pin 2 (T855) or on backplane J1 (RX1) or J5 (RX2) pin 5 when measured with a voltmeter (See Figure 11 - 280 03425-001 Radio backplane for test point location). The following RSSI graphics are given as general information only. Refer to factory technical support only if RX data performance degradation is noticed combined with something that does not look like those RSSI curves.

Note 2: When the synthesizer is unlocked, the front panel green LED called "Supply" will flash indi-
cating that it needs re-tuning. Warning:
The LED will also flash when the unit is in setup mode while connected to the PGM800win program. 5.2.3.1 Initial Setup 1. Shut down power to the base station. 2. Prepare the Multimeter to DC Volts. 3. Remove the exciter (T881, T857) module from the base station rack frame. 4. Remove the exciter top cover (nearest the handle). 5. Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R output and the exciter antenna connector. 6. Connect the Paragon-III Extender Rail Kit to the empty chassis exciter slot. 7. Apply power to the base station. 120 20190-001 29 Paragon-III Technical Manual 5.2.3.2 Synthesizer Alignment Single channel: Connect the Multimeter to either side of L309 (T881) or the long lead of L1 in the VCO (T857) (this measures the synthesizer loop voltage). 1. T881 (800 MHz) Tune VCO trimmer CV300 for a synthesizer loop voltage of 10V DC. 2. T857 (UHF) Tune VCO trimmer C6 for a synthesizer loop voltage of 10V DC. Multiple channels (adjusting as shown for single channel above):
1. T881 (800 MHz) Adjust the VCO loop to 10V using the middle frequency channel. 2. T857 (UHF) Adjust the VCO loop to 10V using the middle frequency channel. All channels should lie within the upper and lower limits of 16V and 3V respectively for the T881 and T857 or within 13V. Note:
Normally, the fast TX key option is installed and the synthesizer is always ener-
gized. In the case where that option was not fitted, key the transmitter by pressing the front panel Carrier button to make the above adjustment possible. 5.2.3.3 TX Frequency Error Adjustment 1. Apply the following settings to the IFR:
- Receiver mode
- Zoom the RF Error window: select 10Khz range IFR RX frequency to match the main radio TX frequency IF Filter set to 30KHz 2. Key the transmitter by pressing the front panel TX-Key button and measure the carrier output frequency. It should be within 300 Hz. If it is not, adjust the TCXO (IC700) to trim to meet the requirement, preferably within 100Hz. 120 20190-001 30 Paragon-III Technical Manual 5.2.3.4 Low-Frequency Balance Adjustment Note:
PGM800Win version 3.00 or later must be used. Electronic potentiometer (256 step) is used to allow channel adjustment of two-point modulation (Low freq. balance). 1. Apply the following settings to the IFR:
Receiver mode and Oscilloscope display (Source Demod out connector, DC coupled). Zoom the Deviation window: select 10kHz Range and DC coupling. IFR RX frequency to match the radio transmit frequency IF Filter set to 30KHz 2. Select the active or, the lowest (in the case of multi-channel base) frequency channel (via dip switch, refer to Figure ) 3. Transmit a square wave by using CDip (using a second serial port). 4. Press EPOTs button. Adjust IC220 via PGM800Win reference modulation to obtain the best square wave, no damping, no overshoot. (You can use either the mouse or up and down arrow keys). Record the deviation read. 5. For single-channel unit, proceed to step 8. 6. For multi-channel unit, select the highest frequency channel. Transmit a square wave via CDip and record deviation again. 7. The difference in deviation between the two channels should be less than 300Hz. If not, re-
adjust IC220 to "average" the square wave shape on both channels until the spec is met. 8. To confirm the adjustment, select the active, or the lowest frequency channel. Compare the de-
viation produced between 1000 Hz sine wave test tone and Random data test pattern The difference between the test tone and the test pattern should be:
For multi-channel unit, repeat this step on the highest frequency channel.
< 1.6 kHz (SRC4FSK, SRC8FSK: HC & NPSPAC)
< 2.1 kHz (SRC4FSK, SRC8FSK, SRC16FSK: FC) 9. Select the active channel. Transmit a TX ON (Modulated) adjustment tone via CDip. Make sure that deviation level read on the IFR correspond to model and bit rate in use. Re-adjust deviation as necessary referring to Checklist B at step 6, page . 5.2.3.5 Exciter Power Output 1. Apply the following settings to the IFR:
IFR RX frequency to match the main radio TX frequency IF Filter set to 30KHz
- Receiver mode, Output T/R
- Select auto range in the Power reading window
- Connect the coaxial cable from the IFR T/R to the Exciter output connector 2. Key the Exciter by pressing the module PTT button. The output power at the coaxial cable end connecting to the power amplifier should be:
- UHF (T857) = 1W 300mW (no adjustment provided)
800 MHz (T881) = 4W 300mW (RV502, Figure 21) 120 20190-001 31 Paragon-III Technical Manual 5.2.4 Power Amplifier Module (T889 (800-870 MHz only), T859)
- Re-install the exciter module into the Paragon-III rack frame.
- Connect the Exciter module to the Power Amplifier.
- Connect the Power Amplifier output to the IFR T/R connector or to a stand-alone BIRD style power meter, terminated with a 150W dummy load.
- Forward and reverse power alarm set (control) are identified on the PA cover. 5.2.4.1 Power Amplifier Power Output
- Key the transmitter on the exciter and adjust the PA output for required output (max 100W for UHF and max 70W for 800) using the front panel power control If power cannot be reached, refer to section 5.2.4.4 for T859 UHF model, or factory technical support for T889 models. Cable loss should be included in the reading. 5.2.4.2 Forward Power Alarm Level (Optional setting) 1. Power up the PA and adjust front panel power control so that the output power is at the alarm level required, usually 20% lower than nominal value (e.g. 40W if the PA normally operates at 50W). 2. Adjust the forward power alarm set (T889: RV101and T859: RV48) so that the forward power alarm LED lights. 3. Adjust front panel power control for the normal operating power level 5.2.4.3 Reverse Power Alarm Level (Optional setting) 1. Power up the PA and adjust the front panel power control for the normal operating power level. 2. Connect an unterminated 3dB 150 W pad to the PA output (e.g. 3:1 VSWR) and adjust the reverse power alarm set (T889: RV105 and T859: RV52) so that the reverse power alarm LED lights. 120 20190-001 32 Paragon-III Technical Manual 5.2.4.4 Tait T859 (UHF) Standard Tuning Procedure 1. For sets with serial numbers following 217262, set RV69 (driver power level) fully clockwise. 2. For all units, preset the tuning controls as shown in Figure 19 Figure 19 - T859 Tuning settings 3. Set RV63 (front panel power control) fully clockwise. 4. Key on the exciter (press PTT button). 5. Adjust CV1 for maximum output. 6. Adjust CV8 for maximum output. 7. Adjust CV32 for maximum output. 8. Adjust CV51 and CV57 for maximum output. 9. Adjust CV34 and CV35 for maximum output. 10. Recheck all settings. The power output should exceed 110W. 11. For sets with serial numbers following 217262, adjust RV69 (driver power level) until 12. For all units, adjust RV63 (front panel power control) to reduce the power output to the required the output power drops to 110W. level (normally 100W). 5.2.4.5 Tait T859 Tuning for Best Efficiency 1. Insert a Shunt current device (HP 34330A Shunt 30A ) between the power supply red wire and its 13.8Vdc output, then connect the shunt to the multimeter (VDC scale) 2. While transmitting, monitor the current. It should remain under 22A. 3. Retune CV32, CV51 and CV57 towards maximum capacitance to obtain minimum supply cur-
rent, but do not exceed a maximum drop of 0.5A per control. 4. Check that the supply current is <22A for 100W output power. Note: These control settings are normally very close to minimum supply current. If the current is re-
duced too far, maximum power output will drop and 2f rejection may degrade. 120 20190-001 33 Paragon-III Technical Manual Figure 20 - T885-0200 Receiver Tuning Controls location 120 20190-001 34 Paragon-III Technical Manual Figure 21 - T881-0200 Exciter Tuning Controls location 120 20190-001 35 Paragon-III Technical Manual IC 310 SK330 pin 2 Figure 22 - T855 Receiver Tuning Controls location 120 20190-001 36 Paragon-III Technical Manual TCXO Figure 23 - T857 Exciter Tuning Controls location 120 20190-001 37 Paragon-III Technical Manual 6.

The T800 is made up of two separate power supply units joined in a single chassis:
A T807 using convection cooling is rated up to 15A at 13.8VDC. It supplies all the radio mod-
ules other than the Power Amplifier. A T808 using convection and fan cooling is rated up to 25A at 13.8VDC. It supplies only the Power Amplifier module. Normally used at room ambient temperatures, they can operate within their specifications over a range of 10 to +60 C. Note: Internal over-temperature protection shuts down the main transformer above 105 degrees Celsius. Both power supply modules are internally connected to ground via their individual, rear-connected, seven-foot standard 120 VAC power cords. Nevertheless, each requires a separate secure electrical ground connection. Individual grounding tabs are provided next to the power connectors. Similarly, the Radio Assembly chassis requires a secure ground connection. A threaded grounding binding post fitted with a knurled binding-nut is provided on the chassis next to DC input 2. Separate grounding leads with appropriate connectors are supplied (either in the courtesy small-parts kit or with one end fastened to the equipment. For each of the power supply modules:
1. Fit one end of the grounding leads push-on connector onto the groun ding tab. For the Radio Assembly chassis:
1. Install the grounding leads lug over the binding post and firmly hand-tighten the binding-nut. For both A and B 2. Fit the slotted connector (on the other end of each of the grounding connector) under a con-
veniently located screw on the rack frame or other support surface. Scrape away paint if needed to ensure clean contact. 3. Apply anti-corrosion compound where paint scraping was done. 4. Ensure by testing continuity that a secure electrical and mechanical connection is achieved. If a DC rail (0V) is installed as part of the system, the grounding leads may alternatively be fitted to the rail terminal. Caution:
Improper grounding between power supply case and rack frame may result in harmful voltage po-
tentials and/or miscellaneous power supply switching noise problems in both receivers and trans-
mitter. Press both red power buttons located on the front of the module to have complete power distribution to the Radio assembly. The power supply front panel LEDs indications are:

Fuse 1 is a 32-volt MDL (slow-blow) 10A Fuse 2 is a 32-volt MDL (slow-blow) 30A Note: the fuses form factor and their locations may differ from Figure 3. 2.3.2 The BDLCPD+ assembly uses a standard 120 VAC power cord. Plug this cord to the rear power outlet shown in Figure 4 and Figure 5. BDLCPD+ assembly Power To check or install a fuse:
1. Open the slide-out fuse drawer located below the power connector by using a fine bladed screw-
driver or a knife blade and gently pry open. 2. Hold the fuse support in one hand and with the other, lift the center plastic retainer until it releases the fuse sliding base. 3. Replace or install a 250V, 2A fuse. 4. To complete the procedure, push the sliding fuse base until it snaps under the retainer. 5. Re-insert the fuse drawer in its housing and push until it is fully seated and closed. When ready to apply power, use the ON-OFF toggle power switch adjacent to the power connector. ON-OFF Switch 120VAC Connector Fuse Slide-out Drawer Use only with a 250 V fuse Employer uniquement av ec un fusible de 250 V Figure 5 - BDLCPD+s rear connection, switch, and fuse 2.4 Antenna Overview 2.4.1 ParagonPD+ commonly uses three antennas (one transmit and two receive) unless a duplexer is used with one of the receive antennas; then only two antennas would be needed. They should be mounted according to any guidelines supplied with the antennas. For antennas placement and spacing, consult System Engineering. 2.4.2 1- Route good quality 50-ohm double-shielded coaxial cable(s) (e.g. RG-214 or Heliax) from the Cabling and Connection selected antenna position(s) to the ParagonPD+ Radio assembly. 2- Terminate the RX-1 and RX-2 cable ends at the Receiver modules rear position with an N-type connector. 3- Similarly, terminate the TX cable end at the Power Amps module rear position with an N -type connector. Caution:
When terminating RF cables use brand-name crimping tools (such as AMP, Jensen, CrimpMas-
ter, etc) of the correct size for the cable and type of connector used. Common pliers are NOT acceptable. 120 20180-100a Preliminary 7 ParagonPD Technical Manual 2.5 Completing the physical Installation. ParagonPD+ products are factory-configured to users requirements and are shipped ready to run. After new installations:
Re-check that all connections are secure on radio and BDLCPD+ assemblies (antennas, PC, power cords etc.) Check that fuses are inserted. Turn both BDLCPD+ and radio power ON. You are now ready to check for normal operation (as per paragraph 2.6) and to run the Dataradio Windows Radio Installation Software (WinRIS) program for testing or trouble-shooting. Any change(s) to the settings must be done via files saved on diskette and loaded into the unit using the WinRIS program. 2.6 Checking out Normal Operation 1- Check that power is applied. 2- Check Radio assembly lights for proper operation as per section 3.1.1 3- Check for proper operation of the BDLCPD+s LEDs as per se ction 3.2.1.5. 4- Using the WinRIS program and an in-line wattmeter, check forward & reverse power to confirm main antenna installation (as per section 4) 5- Using WinRIS, check the RF Data Link with a mobile that can be heard (as per section 4.3.1) If user application and mobiles are available, test the installation by going through a normal sequence of transmitting and receiving messages. 120 20180-100a Preliminary 8 ParagonPD Technical Manual 3.

The rack-mounted BDLCPD+ is housed in a steel case. It has no user serviceable parts. Units configur a-
tion is stored in flash memory (EEPROM). 3.2.1 BDLCPD+ Front panel Referring to Figure 2, the front panel of the BDLCPD+ has two cutouts across its length. A- The left cutout groups the units type label and ten LED indicators:
The S3 label designates the BDLCPD+ as a three Serial-port model
(Ports 4 and 5 are reserved for future use) The RF group of 3 LEDs The RS-232 group of 5 LEDs A single CK LED 120 20180-100a Preliminary 12 ParagonPD Technical Manual The ALARMS group of 4 LEDs B- The right cutout groups two tactile (membrane) switches (PF1 and RESET). 3.2.1.1 Front Switches The BDLCPD+ uses two membrane-type switches labeled:
RESET PF 1 These switches indicate contact by emitting a short BEEP tone when pressed. PF1 RESET Figure 11 - BDLCPD+ membrane switches Reset 3.2.1.1.1 Pressing Reset produces the same result as powering OFF and ON again. It restarts the microprocessor, the peripherals and invokes the on-board diagnostics. BDLCPD+s radio modules internal flash-memories are read and their values are loaded in system SRAM CPU flash-memory. Normally, pressing Reset results in one short BEEP tone followed by all LEDs coming ON for about four seconds. Then, the LEDs flash in a ripple pattern for close to two seconds indicating diagnostics are in progress. At the end of this period, all LEDs should be OFF except CK that should flash about six to eight times per second. Expect an additional two seconds delay for CK to start flashing and the UF indicator to come ON if the radio assembly is not connected or not powered (see section 3.2.1.5.4 for Alarm details). PF 1 3.2.1.1.2 PF 1 is a multi-function switch:
It clears LED error indications It initiates test transmissions It sets the function of the RS-232 LEDs Clearing Errors 3.2.1.2 Major and minor error LED indications remain lit on the front panel until:
The unit is RESET The unit is powered OFF and ON again PF 1 is pressed The PF 1 switch can be pressed at any time to clear an error display without affecting normal operations. Test Transmissions 3.2.1.3 To select a pattern and begin transmission, start by pressing and holding PF1. It beeps once, all five RS232 LEDs light; listen for a second beep followed by a third beep. After two seconds, the unit beeps and goes in TX Select mode with only the three rightmost RS-232 LEDs now used as selection indic a-
tors. Only release PF1 after the third beep. Following release:
Start of selection must be made within two seconds. If not, the unit will default to pattern one and start test transmitting. 120 20180-100a Preliminary 13 ParagonPD Technical Manual PF1 may be pressed more than once. The number of times it is pressed determines the type of pattern that will be transmitted according to Table 4. Each pressing of PF1 extends the two-second timer. The three rightmost RS-232 LEDs are used to indicate TX mode selection as shown in Table 3. Table 3 - TX mode selection LEDs indications TX pattern se-

* Dotting with reduced amplitude Notes:
For DGMSK models, a dotting pattern consists of an alternating series of bits. For the xRC4FSK models, a dotting pattern consists of an alternating series of bits where only the lowest-level symbols modulation is used. The square wave is used to check transmitter low frequency balance.. Pattern 6 produces a transmission of approximately 55 seconds followed by about 55 seconds of silence. Initial transmission in a sequence may be shorter than 55 seconds. TX LED stays steadily red for duration of the test. Press PF1 to terminate beacon mode.
Once the type of transmission is selected, stop pressing PF1, allow the two-seconds timer to run down. Automatically, the BDLCPD+ turns its transmitter ON, sends the selected test pattern for 55 seconds, 120 20180-100a Preliminary 14 ParagonPD Technical Manual and turns its transmitter OFF. The TX LED in the RF group of indicators lights in red while test trans-
mitting. Pressing PF1 while the 55 seconds test is in progress stops the test. At the end of test transmission, BDLCPD+ operation returns to normal and the RX LED lights in green
(monitoring normal transmitter activity). RS-232 LED Function Selection 3.2.1.4 The PF 1 button is used to select the RS-232 display mode as follows:
If pressed ONCE (do not hold pressed):
- Clears Alarm indications
- CK LED stops flashing for 2 seconds
- During this time, one or all of the RS-232 numbered LEDs (see Figure 13) will light. If one LED lights, it denotes the port to which the subsequent display applies. If all numbered LEDs light, it denotes that the normal 3-port display mode is active. The selected display remains active until manually changed or until RESET is pressed or until power up. Table 5 - RS-232 LED Function Selection Sequence RS-232 LED Function Selection Sequence ALL 1 2 3 4 (reserved) 5 (reserved) ALL 1 2 3 4 (reserved) 5 (reserved) TX LED in RF group lights with any and all transmission TX LED in RF group only lights with an ACK or DATA transmission If, during the 2 seconds period that CK is not flashing, PF 1 is pressed a second time, the LED func-
tions will advance one step from top to bottom through the available options in the order shown in Table 5. PF 1 may be pressed repeatedly during the 2 second period (extended with each press) to advance to the desired numbered LED function option. Once the desired RS-232 LED function is selected, stop pressing PF1, allow the two-seconds timer to run down. The BDLCPD+ returns to normal operation using the newly selected display. 3.2.1.5 LEDs and Indications LEDs are used to indicate the operation status of the BDLCPD+. Although capable of displaying three col-
ors, only the green and red colors are used for the BDLCPD+. They are grouped by their function:
RF Group, displays radio channel status in green RS-232 Group, displays serial port status in green except the TX LED that also uses red ALARM Group, displays fault status in red 120 20180-100a Preliminary 15 ParagonPD Technical Manual 3.2.1.5.1 Radio Network Indicators The Radio Network LEDs are useful when troubleshooting as an indication of network activity. It can help isolate transmission problems. CS RX TX Carrier Sense - Steady light indicates that an incoming radio data signal is being detected by the DSP modem. CS signal is not user-adjustable. Receive Data Flashing light indicates unit is internally receiving data from the radio network. Transmitter ON blinks green indicates (depending on display mode selected):
That a data packet or ACK (packet acknowledgment) is being transmit-
ted. That an idle packet, data packet or ACK is being sent. Test transmission display is done in red. CS RX TX RF Figure 12 - RF indicators RS-232 Port Indicators 3.2.1.5.2 The RS-232 LEDs normally indicate port activity on the port selected. See section 3.2.1.4 above for in-
structions for selecting display mode. CM Command Mode - LED lights and remains lit while the selected port is accessing the Command FR FT RD TD Processor. It lights ON and OFF while being configured. Flow Control on Receive - the BDLCPD+ has received a flow control signal from the device con-
nected to it. When it lights, BDLCPD+ has stopped sending data to the DTE. When LED goes out, the port terminal is again ready to receive data. Flow Control on Transmit - the BDLCPD+ has sent a flow control signal to the DTE asking it to stop sending data. The LED remains lit as long as the terminal is being held off. Receive Data - when lit, it shows that the Receive Data pin 3 on the RS-232 interface connector is active. Since all BDLCPD+ are configured as DCE, it means that the DTE is receiving data from the BDLCPD+. Transmit Data - shows the status of Transmit Data pin 2 of the RS-232 interface. When lit, the DTE is sending data to the BDLCPD+. C M FR FT RD TD 1 3 2 R S-232 3.2.1.5.3 CK Check and Power LEDs Figure 13 - RS-232 LED Port indicators Check:
Normally flashing rapidly (about 6 cps), indicates microprocessors are working correctly and power is applied. Not flashing indicates unit is not functioning. Blinking slowly (1 cps), indicates the parameters contents of the flash memory have been cor-
rupted. The unit automatically loads its set of factory default parameters and starts beeping at 20 seconds intervals. May also indicate DSP-modem re-initialization has occurred 120 20180-100a Preliminary 16 ParagonPD Technical Manual Alarm Indicators 3.2.1.5.4 All alarm conditions will cause the BDLCPD+ to light one or more of the LED indicators. LEDs remain ON when lit until cleared by either pressing PF 1 (without affecting operation of the unit) or RESET (cy-
cling unit OFF and ON). LM Local Minor Alarm - when lit, indicates the presence of any of the following minor faults:
- Parity, framing or overrun error at any RS-232 port.
- Out of buffers. No memory available to accept data from a local terminal device. Usually de-
notes a flow control problem.
- Flash memory error. At power-up or reset, the unit detected a change in non-volatile memory. RM Remote Minor Alarm - when lit, indicates any of the Local Minor Alarm listed above have taken place at the remote end of the link (i.e. the mobile the local base station is currently communi-
cating with). It will also light when a protocol error has been detected on the network. LF UF In a network using the Host Link Active (MSC) feature, the RM LED, flashing in-sync with the CK LED, indicates that the link is down. Link Failure - when lit, indicates that the base station fails to receive an ACK for a packet sent and for all subsequent retries. Some data has possibly been lost. LF is not functional if all active ports are set to NAR mode. Link fails are inevitable during normal operation (mobiles temporarily out of range, in a tunnel, parked in a dead spot, etc.). A lit LF LED is not normally cause for concern. Unit Failure - when lit, the unit requires attention:
- The BDLCPD+ is not operable;
It may indicate detection of a system software error trap.
- The BDLCPD+ is operable;
Indicates that on power-up, invalid data was detected in the serial EEPROM chip (located in the radio modules). It may also indicate that connection to the radio modules is incorrect or that radio power is not applied. The LM, RM and UF alarms also sound a beep when a fault occurs. The LF alarm is silent.

To set a default channel via the software, all DIP switches must be set to OFF (i.e. 00000000). When a switch is Off, its binary count is active; when a switch is ON its binary count is inactive. The various DIP switch combinations of ON or OFF make up a binary total, which identifies the channel number. To select a channel, set the appropriate DIP switch or switches to OFF to make the binary count total the channel number you want. Set all other switches to ON. It is recommended to set both SW1 (RX) and SW2 (TX) to the same settings on both back plane boards. Example: To select channel 5, set the DIP switches as shown below:

Note 2: When the synthesizer is unlocked, the front panel green LED called "Supply" will flash indicating that it needs re-tuning. Warning, The LED will also flash when the unit is in setup mode while connected to the PGM800win program. 5.2.2.1 Initial Setup This initial setup will be used during all receiver alignment procedures described below:
1. Remove the receiver (T885, T855 or T835) module from the ParagonPD+ rack frame 2. Remove the receiver top cover (nearest the handle). 3. Connect the ParagonPD+ Extender Rail Kit for Series II to the empty chassis receiver slot. 4. Prepare the Multimeter to DC Volts. 5. Apply power to the ParagonPD+. 5.2.2.2 Synthesizer Alignment Single channel: Connect the Multimeter to either side of L504 (T885) or the long lead of L1 (T855 and T835) in the VCO (this measures the synthesizer loop voltage). 1. T885 (800/900 MHz) Tune VCO trimmer CV500 for a synthesizer loop voltage of 10VDC. 2. T855 (UHF) Tune VCO trimmer C6 for a synthesizer loop voltage of 10V DC. 3. T835 (VHF). Tune VCO trimmer CV1 for a synthesizer loop voltage of 9VDC. Multiple channels (adjusting as shown for single channel above):
1. T885 (800/900 MHz) Adjust the VCO loop to 10V using the middle frequency channel. 2. T855 (UHF) Adjust the VCO loop to 10V using the middle frequency channel. 3. T835 (VHF) Adjust the VCO loop to 9V using the middle frequency channel. 4. All channels should lie within the upper and lower limits of respectively All channels should lie within the upper and lower limits of 16V and 3V respectively for the T885 and T855 or within 13V and 5V for the T835. 120 20180-100a Preliminary 33 ParagonPD+ Technical Manual 5.2.2.3 Front-End Alignment 1. IFR COM120B settings:
a) Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R output and the receiver antenna connector. b) Select the generator mode (GEN button) and set to the main receiver channel frequency c) Select and turnon GEN2 d) Set the FM Deviation to 3kHz (full channel) or 1.5kHz (half channel) using 1KHz sine e) Select SINAD meter f) Use a X1 scope probe connected to SINAD input and monitor the Discriminator O/P on the back-
plane at SK1 pin 6 (RX-audio1). Alternately, it is also possible to monitor at the receiver I/O Pad P207 (T885), the receiver TP314 (T855) or at the receiver IC350 pin 7 (T835). 2. Adjust the helical resonators for best SINAD: #H400, #H401 and #H900 (T885); #FL410 and #FL420
(T855) or L410, L420, L460 and L470 (T835). 3. Continually decrease the RF level to reach 12dB SINAD, then re-do step 2) & 3) again. The absolute minimum requirement level to reach is -108dBm (typical level is -109 to -110 dBm) 4. Perform the SINAD linearity tests described in paragraph 5.2.2.4. If it fails to pass the requirement, contact your Dataradio technical support. WARNING: Do NOT attempt to re-tune the IF stages
(I.e. L300 and L301 for T885, L310 to L390 for T855 or L330 to L360 and CV318 for T835). These adjustments do not need to be re-adjusted after frequency re-programming. Touch-
ing these coils will have a direct impact on the modem DSP ISI coefficient settings and may reduce significantly the radio performances over data. 5.2.2.4 SINAD and Linearity Check 1. Apply the following settings to the IFR COM-120:
a) Generator mode, Output T/R, TX frequency to match the main radio RX frequency b) Filter set to wide band (no audio filter) c) Select Gen2 (Modulating tone fixed to 1KHz). All other Gen must be off. d) Set deviation to 3.0KHz for full channel or 1.5KHz for half channel radios. e) Use a X1 scope probe connected to the IFR SINAD input and monitor the Discriminator O/P on the radio backplane at SK1 pin 6 (RX-audio1). Alternately, it is also possible to monitor at the receiver I/O Pad P207 (T885), the receiver TP314 (T855) or at the receiver IC350 pin 7 (T835). 2. Lower the RF level to get a 12dB SINAD reading. Level should be better than -108dBm (including ca-
ble loss). 3. Offset the IFR TX frequency 2kHz (full channel) or 1kHz (half / NPSPAC channel) above the main radio RX frequency, record the SINAD reading. It should remain within 1.5 dB from the on frequency SINAD reading. For T885 and T855, use above values, for T835 use 1.5kHz (full channel) or 0.8kHz
(half channel). 4. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half / NPSPAC channel) below the main radio RX frequency, record the SINAD reading. It should remain within 1.5 dB from the on-frequency SINAD reading. For T885 and T855, use above values, for T835 use 1.5kHz (full channel) or 0.8kHz
(half channel). Note: If one of the above requirements is not met, try to re-tune the front-end. If still failed, contact your Dataradio technical support. 120 20180-100a Preliminary 34 ParagonPD+ Technical Manual 5.2.2.5 RSSI Adjustment

Tune VCO trimmer CV1 for a synthesizer loop voltage of 9VDC. 120 20180-100a Preliminary 36 ParagonPD+ Technical Manual Multiple channels (adjusting as shown for single channel above):
1. T881 (800/900 MHz) Adjust the VCO loop to 10V using the middle frequency channel. 2. T857 (UHF) Adjust the VCO loop to 10V using the middle frequency channel. 3. T837 (VHF) Adjust the VCO loop to 9V using the middle frequency channel. All channels should lie within the upper and lower limits of 16V and 3V respectively for the T881 and T857 or within 13V and 5V for the T837. Note:
Normally, the fast TX key option is installed and the synthesizer is always ener-
gized. In the case where that option was not fitted, key the transmitter by pressing the front panel Carrier button to make the above adjustment possible. 5.2.3.3 TX Frequency Error Adjustment 1. Apply the following settings to the IFR:
- Receiver mode
- Zoom the RF Error window: select 10Khz range IFR RX frequency to match the main radio TX frequency IF Filter set to 30KHz 2. Key the transmitter by pressing the front panel TX-Key button and measure the carrier output frequency. It should be within 300 Hz. If it is not, adjust the TCXO (IC700) to trim to meet the requirement, preferably within 100Hz. 5.2.3.4 Low-Frequency Balance Adjustment Note:
PGM800Win version 3.00 or later must be used for T881 adjustments and can also be used to adjust T857 and T837 units. Electronic potentiometer (256 step) is used to allow channel adjustment of two-point modulation (Low freq. balance). PGM800Win version 3.00 or later must be used, if the unit serial number is longer than 6 digits. 1. Apply the following settings to the IFR:

For multi-channel unit, select the highest frequency channel. Transmit a square wave by pressing the BDLCPD+s PF1 button and following the procedure outlined in section 3.2.1.3. Record de-
viation again. 7. The difference in deviation between the two channels should be less than 300Hz. If not, re-
adjust IC220 to "average" the square wave shape on both channels until the spec is met. 8. To confirm the adjustment, select the active, or the lowest frequency channel. Compare the de-
viation produced between 1000 Hz sine wave test tone and Random data test pattern The difference between the test tone and the test pattern should be:
< 600 Hz (DGMSK)
< 1.5 kHz (xRC4FSK, xRC8FSK, HC)
< 2.0 kHz (xRC4FSK, xRC8FSK, FC/NPSPAC). For multi-channel unit, repeat this step on the highest frequency channel. 9. Select the active channel. Transmit a TX ON (Modulated) adjustment tone by pressing the BDLCPDs PF1 button and following the procedure outlined in section 3.2.1.3. Make sure that deviation level read on the IFR correspond to model and bit rate in use (see Figure 16).

For all units, adjust RV63 (front panel power control) to reduce the power output to the required level (normally 100W). 5.2.4.5 Tait T859 Tuning for Best Efficiency 1. Insert a Shunt current device (HP 34330A Shunt 30A ) between the power supply red wire and its 13.8Vdc output, then connect the shunt to the multimeter (VDC scale) 2. While transmitting, monitor the current. It should remain under 22A. 120 20180-100a Preliminary 39 ParagonPD+ Technical Manual 3. Retune CV32, CV51 and CV57 towards maximum capacitance to obtain minimum supply cur-
rent, but do not exceed a maximum drop of 0.5A per control. 4. Check that the supply current is <22A for 100W output power. Note:
These control settings are normally very close to minimum supply current. If the current is re-
duced too far, maximum power output will drop and 2f rejection may degrade. 5.2.5 (TPL) LMS series Power amplifier (PA8-2BF-LMS) (890-960 MHz) Note:

Using the WinRIS, press TX ON (Modulated) and record deviation level as read on the IFR. 2. Using Windows Notepad, Edit the .bp2 file named with the corresponding BDLCPD+ serial number (e.g. abcd.bp2). Save as to another file name and keep it in case something goes wrong while changing a parameter. 3. Locate the line labeled Dev0 Par85= and record the value beside the = sign. This is the corresponding parameter value to the deviation read in step 1. 4. Apply the following formula to determine the new parameter value to be set:
(New Par85 value) = [(initial Par85 value) X (target deviation) / (deviation read)] + 2 5. Change the value in the file, Save as using the BDLC PD+ serial number file name. 6. Run the WinRIS again and do a Put From. From the opened window, select the file that you just made the change to and then press OK 7. Again, check deviation level while pressing TX ON (Modulated). If the level is now correct, press StationReset to make the change permanent. Otherwise do step 5 again, changing the value entered in the file by 1 or 2 digit(s) up or down, fine-tuning directly the Par85 (DSP deviation) parameter. Do steps 6 and 7 again to confirm acceptance. This last step may have to be repeated once or twice while varying the entered value up or down. If unable to obtain the correct level after editing up and/or down by no more than 2, contact System Engineering. 120 20180-100a Preliminary 48 ParagonPD+ Technical Manual 6.

dio assembly A dual power supply assembly A Dataradio BDLCPD model A Radio Interface Cable to link the Radio assembly to the BDLCPD:
18-inch long Y cable; DB-25 female to dual DB-25 female (p/n 730 03374-
102) for connection between backplane PCBs and BDLCPD. One standard seven-foot 120VAC power cord Two DC power cables to connect the radio assembly to the dual power supply assem-
bly. Courtesy small parts kit Frequently, ParagonPD product components are field-assembled prior to customer delivery. The cabinetry may then be supplied in one of several custom rack-mount configurations that may also include fan, backhaul modems, duplexer/filters/combiners, and ancillary equipment. If damage has occurred to the equipment during shipment, file a claim with the carrier immedi-
ately. 2.1 Overview The cabinet and rack-mount housing the Para-
gonPDs Radio assembly and the BDLCPD is generally installed in a sheltered facility. Occa-
sionally located adjacent to the nerve center of the users network, it is often located near tower sites or at remote locations where it operates unattended. Furnishings needed include power, cabling and installation of antenna, landline or microwave modem and host PC or portable computer. De-
tails of these are outside the scope of this man-
ual. This manual covers the radio assembly and the BDLCPD that includes the modem. 2.2 Location Be sure to place the ParagonPD in such a way that:
The LEDs can be seen (as an aid in trouble-
shooting) Access to the antenna connector and to the back connectors is possible without remov-
ing the unit Sufficient air may flow around the unit to provide adequate cooling. 2.3 Electrical Standard 120 VAC electrical power is required. It should be capable of providing at least 10A to power ParagonPD (<6A) and ancillary equip-
ment. 120 20170-202 4 ParagonPD Technical Manual Air Flow Receiv er E xc ellence in R adio C ommunic at ions Receiv er Exciter Pow er Amp lifi er S peaker Panel Gating Sensitivi ty Gate Line Le vel Supply Monitor Volume O ff O n Monitor Mute Supply L ow Forw ard P ower Hi gh Re ver se Power Pow er Gating Sensitivi ty Gate Car ri er O n Line Le vel Supply Supply Line Sensitivi ty Microphone Monitor Volume O ff O n Monitor Mute SP EAK ER SELE CT SWI TCH R X1 R X2 OFF p rogra mmin g po rt Dual Power Supply Module OL Stby On Power OL Stby On Power Figure 1 Typical radio and power supply assemblies, front view T800 II Slimline CM FR FT RD TD 1 3 2 RS-232 CK LM LF RM UF ALARMS PF1 RES ET S-3 CS T X RX RF Figure 2 - BDLCPD, front view 120 20170-202 5 ParagonPD Technical Manual REAR VIEW Air Flow FAN _ +

cally rack-mounted right below the main assem-
bly radio chassis. The T800 is made up of two separate power supply units joined in a single chassis:
A T807 using convection cooling is rated up to 15A at 13.8VDC. It supplies all the radio modules other than the Power Amplifier. A T808 using convection and fan cooling is rated up to 25A at 13.8VDC. It supplies only the Power Amplifier module. Normally used at room ambient temperatures, they can operate within specifications over a range of 10 to +60 C. Note: Internal over-temperature protection shuts down the main transformer above 105 degrees Celsius. Both power supply modules are internally con-
nected to ground via their individual, rear-
connected, seven-foot standard 120 VAC power cords. Nevertheless, each requires a separate secure electrical ground connection. Individual grounding tabs are provided next to the power connectors. Similarly, the Radio Assembly chassis requires a secure ground connection. A threaded grounding binding post fitted with a knurled binding-nut is provided on the chassis next to DC input 2. Separate grounding leads with appropriate con-
nectors are supplied (either in the courtesy small-parts kit or with one end fastened to the equipment. A- For each of the power supply modules:
1. Fit one end of the grounding leads push-on connector onto the grounding tab. B- For the Radio Assembly chassis:
1. Install the grounding leads lug over the binding post and firmly hand-
tighten the binding-nut. For both A and B 2. Fit the slotted connector (on the other end of each of the grounding connector) under a conveniently located screw on the rack frame or other support surface. Scrape away paint if needed to ensure clean contact. 3. Apply anti-corrosion compound where paint scraping was done. 4. Ensure by testing continuity that a se-
cure electrical and mechanical connec-
tion is achieved. If a DC rail (0V) is installed as part of the sys-
tem, the grounding leads may alternatively be fitted to the rail terminal. Caution:
Improper grounding between power supply case and rack frame may result in harmful voltage potentials and/or miscellaneous power supply switching noise problems in both receivers and transmitter. Press both red power buttons located on the front of the module to have complete power distribution to the Radio assembly. The power supply front panel LEDs indications are:

1. Open the slide-out fuse drawer located be-
low the power connector. 2. Use a fine bladed screwdriver or a knife blade and gently pry open. 3. Hold the fuse support in one hand and with the other, lift the center plastic retainer until it releases the fuse sliding base. 4. Replace or install a 250V, 2A fuse. 5. To complete the procedure, push the sliding fuse base until it snaps under the retainer. 6. Re-insert the fuse drawer in its housing and push until it is fully seated and closed. When ready to apply power, use the ON-OFF toggle power switch adjacent to the power con-
nector.

They should be mounted according to any guidelines supplied with the antennas. For antennas placement and spacing, consult System Engineering. 2.4.2 Cabling and Connection 1- Route good quality 50-ohm double-shielded coaxial cable(s) (e.g. RG-214 or Heliax) from the selected antenna position(s) to the ParagonPD Radio assembly. 2- Terminate the RX-1 and RX-2 cable ends at the Receiver modules rear position with an N-type connector. 3- Similarly, terminate the TX cable end at the Power Amps module rear position with an N-type connector. Caution:
When terminating RF cables use brand-name crimping tools
(such as AMP, Jensen, Crimp-
Master, etc) of the correct size for the cable and type of connector used. Common pliers are NOT ac-
ceptable. 2.5 Completing the physical Installation. ParagonPD products are factory-configured to users requirements and are shipped ready to run. After new installations:
Re-check that all connections are secure on radio and BDLCPD assemblies (antennas, PC, power cords etc.) Check that fuses are inserted. Turn both BDLCPD and radio power ON. You are now ready to check for normal opera-
tion and to run the Windows Radio Installation Software (WinRIS) program for testing or trou-
ble-shooting. Any change(s) to the settings must be done via files saved on diskette and loaded into the unit using the WinRIS program. 120 20170-202 8 ParagonPD Technical Manual 2.6 Checking out Normal Operation 1- Check that power is applied. 2- Check Radio assembly lights for proper op-
eration as per section 3.1.1 3- Check for proper operation of the BDLCPDs LEDs as per section 3.2.1.2. 4- Using the WinRIS program (described in section 4), and an in-line wattmeter, check the forward & reflected power to confirm antenna installations. 5- Using the WinRIS, check the RF link with a mobile station that can be heard, by using the WinRIS Ping feature. See section 4.4.5.5 If user application and a mobile station are available, test the installation by going through a normal sequence of transmitting and receiving messages. 3.

RJ11 connector Mirrors the one on the front of the Speaker panel (series connected 120 20170-202 11 ParagonPD Technical Manual to both backplanes). Used for programming the Radio Assembly whenever the speaker panel has been removed. This feature is exclusive to the Series II model. Series I models programming is done externally via EPROMs. DB-25M plug at PL1 (one side of the Y cable on each PCB) used to supply the re-
ceive signal to the BDLCPDs single EXT.RADIO/TEST DB-25F plug. Two channel-select DIP switches (SW1 and SW2) This feature is exclusive to the Series II model. Cooling fan driver CN2 located on back-
plane connects to the horizontally-mounted fan on top of the Radio assembly and acti-
vated by BDLCs PTT signal. Coaxial relay driver not used. 3.2 BDLCPD The rack-mounted BDLCPD is housed in a steel case. It has no user serviceable parts. Units configuration flash memory
(EEPROM). is stored in 3.2.1 BDLCPD Front panel Referring to Figure 2, the front panel of the BDLCPD has two cutouts across its length. A- The left cutout groups the units type label and ten LED indicators:
The S3 label designates the BDLCPD as a three Serial-port model
(Ports 4 and 5 are reserved for future use) The RF group of 3 LEDs The RS-232 group of 5 LEDs A single CK LED The ALARMS group of 4 LEDs B- The right cutout groups two tactile (mem-
brane) switches (PF1 and RESET). Front Switches 3.2.1.1 Referring to Figure 11, the BDLCPD uses two membrane-type switches labeled:
RESET PF 1 These switches indicate contact by emitting a short BEEP tone when pressed. PF1 RESET Figure 11 - BDLCPD membrane switches Reset 3.2.1.1.1 Pressing Reset produces the same result as pow-
ering OFF and ON again. It restarts the micro-
processor, the peripherals and invokes the on-
board diagnostics. BDLCPDs radio modules internal flash-memories are read and their val-
ues are loaded in system SRAM CPU flash-
memory. Normally, pressing Reset results in one short BEEP tone followed by all LEDs coming ON for about four seconds. Then, the LEDs flash in a ripple pattern for close to two seconds indi-
cating diagnostics are in progress. At the end of this period, all LEDs should be OFF except CK that should flash about six to eight times per second. Expect an additional two seconds delay for CK to start flashing and the UF indicator to come ON if the radio assembly is not connected or not powered (see section 3.2.1.2.4 for Alarm de-
tails). PF 1 3.2.1.1.2 PF 1 is a multi-function switch:
It clears LED error indications It initiates test transmissions It sets the function of the RS-232 LEDs 120 20170-202 12 ParagonPD Technical Manual Clearing Errors 3.2.1.1.2.1 Major and minor error LED indications remain lit on the front panel until:
The unit is RESET The unit is powered OFF and ON again PF 1 is pressed The PF 1 switch can be pressed at any time to clear an error display without affecting normal operations. Test Transmissions 3.2.1.1.2.2 To select a pattern and begin transmission, start by pressing and holding PF1. It beeps once, all five RS232 LEDs light; listen for a second beep followed by a third beep. After two seconds, the unit beeps and goes in TX Select mode with only the three rightmost RS-232 LEDs now used as selection indicators. Only release PF1 after the third beep. Following release:
Start of selection must be made within two seconds. If not, the unit will default to pat-
tern one and start test transmitting. PF1 may be pressed more than once. The number of times it is pressed determines the type of pattern that will be transmitted ac-
cording to Table 3. Each pressing of PF1 extends the two-
second timer. The three rightmost RS-232 LEDs display are used to indicate TX mode selection as shown in Table 2. Table 2- TX mode selection LEDs indications TX pattern selected Binary TX mode LED indications FT LED RD LED TD LED 1 2 3 4 5 6 7 Off Off Off On On On On Off On On Off Off On On On Off On Off On Off On Once the type of transmission is selected, stop pressing PF1, allow the two-seconds timer to run down. Automatically, the BDLCPD turns its transmitter ON, sends the selected test pattern for 55 seconds and turns its transmitter OFF. The TX LED in the RF group of indicators lights in red while test transmitting. Pressing PF1 while the 55 seconds test is in progress stops the test. At the end of test transmission, BDLCPD opera-
tion returns to normal and the RX LED lights in green (monitoring normal transmitter activity). Table 3 - Test Transmissions

tion measurements. Pattern 6 produces a transmission of approximately 55 seconds followed by about 55 seconds of silence. Initial transmission in a sequence may be shorter than 55 seconds. TX LED stays steadily red for dura-
tion of the test. Press PF1 to terminate beacon mode. 120 20170-202 13 ParagonPD Technical Manual 3.2.1.1.2.3 RS-232 LED Function Selection The PF 1 button is used to select the RS-232 display mode as follows:
If pressed ONCE (do not hold pressed):
- Clears Alarm indications
- CK LED stops flashing for 2 seconds
- During this time, one or all of the RS-232 numbered LEDs (see Figure 13) will light. If one LED lights, it denotes the port to which the subsequent display applies. If all numbered LEDs light, it denotes that the normal 3-port display mode is active. The selected display remains active un-
til manually changed or until RESET is pressed or until power up.

PF 1 may be pressed repeatedly during the 2 second period (extended with each press) to advance to the desired numbered LED function option. Once the desired RS-232 LED function is se-
lected, stop pressing PF1, allow the two-seconds timer to run down. The BDLCPD returns to nor-
mal operation using the newly selected display. 3.2.1.2 LEDs and Indications LEDs are used to indicate the operation status of the BDLCPD. Although capable of displaying three colors, only the green and red colors are used for the BDLCPD. They are grouped by their function:
RF Group, displays radio channel status in green RS-232 Group, displays serial port status in green except the TX LED that also uses red ALARM Group, displays fault status in red Radio Network Indicators 3.2.1.2.1 The Radio Network LEDs are useful when trou-
bleshooting as an indication of network activity. It can help isolate transmission problems.

mitted. That an idle packet, data packet or ACK is being sent. Test transmis-
sion display is done in red. RS-232 Port Indicators 3.2.1.2.2 The RS-232 LEDs normally indicate port activ-
ity on the port selected. See section 3.2.1.1.2.3 above for instructions for selecting display mode. 120 20170-202 14 ParagonPD Technical Manual C M 1 F R F T R D 3 2 R S -232 T D Figure 13 - RS-232 Port LED indicators FR CM Command Mode - LED lights and re-
mains lit while the selected port is ac-
cessing the Command Processor. It lights ON and OFF while being config-
ured. Flow Control on Receive - the BDLCPD has received a flow control signal from the device connected to it. When it lights, BDLCPD has stopped sending data to the DTE. When LED goes out, the port terminal is again ready to re-
ceive data. Flow Control on Transmit - the BDLCPD has sent a flow control signal to the DTE asking it to stop sending data. The LED remains lit as long as the terminal is being held off. FT RD TD Receive Data - when lit, it shows that the Receive Data pin 3 on the RS-232 interface connector is active. Since all BDLCPD are configured as DCE, it means that the DTE is receiving data from the BDLCPD. Transmit Data - shows the status of Transmit Data pin 2 of the RS-232 in-
terface. When lit, the DTE is sending data to the BDLCPD. 3.2.1.2.3 CK Check and Power Check:
Normally flashing rapidly (about 6 cps), indicates microprocessors are working correctly and power is applied. Not flashing indicates unit is not func-
tioning. Blinking slowly (1 cps), indicates the parameters contents of the flash memory have been corrupted. The unit automati-
cally loads its set of factory default pa-
rameters and starts beeping at 20 sec-
onds intervals. May also initialization has occurred indicate DSP-modem re-
Alarm Indicators 3.2.1.2.4 All alarm conditions will cause the BDLCPD to light one or more of the LED indicators. LEDs remain ON when lit until cleared by either pressing PF 1 (without affecting operation of the unit) or RESET (cycling unit OFF and ON). LM RM LF UF ALARMS Figure 14 - ALARMS LED indicators LM Local Minor Alarm - when lit, indicates the presence of any of the following mi-
nor faults:
- Parity, framing or overrun error at any RS-232 port.
- Out of buffers. No memory available to accept data from a local terminal de-
vice. Usually denotes a flow control problem.
- Flash memory error. At power-up or reset, the unit detected a change in non-
volatile memory. RM Remote Minor Alarm - when lit, indi-
cates any of the Local Minor Alarm listed above have taken place at the re-
mote end of the link (i.e. the mobile the local base station is currently communi-
cating with). It will also light when a protocol error has been detected on the network. In a network using the Host Link Ac-
tive (MSC) feature, the RM LED, flashing in-sync with the CK LED, indi-
down. cates link that the is 120 20170-202 15 ParagonPD Technical Manual UF LF Link Failure - when lit, indi-
cates that the base station fails to re-
ceive an ACK for a packet sent and for all subsequent retries. Some data has possibly been lost. LF is not functional if all active ports are set to NAR mode. Link fails are inevitable during normal operation (mobiles temporarily out of range, in a tunnel, parked in a dead spot, etc.). A lit LF LED is not normally cause for concern. Unit Failure - when lit, the unit requires attention:
- The BDLCPD is not operable;
It may indicate detection of a system software error trap.
- The BDLCPD is operable;
Indicates that on power-up, invalid data was detected in the serial EEPROM chip (located in the radio modules). It may also indicate that connection to the radio modules is incorrect or that radio power is not applied. The LM, RM and UF alarms also sound a beep when a fault occurs. The LF alarm is silent. 3.2.2 BDLCPD Rear panel Referring to Figure 4, the rear panel of the BDLCPD has the following set of chassis con-
nectors:
Four DE-9F connectors:

Figure 15 - BDLCPD Y cable and pinout Important note:
The aggregate total baud rate for all active ports on a BDLCPD must not exceed 30,000 for Para-
gonPD. Sustained simultaneous operation on devices 1 and 3, using the factory settings for these ports, may result in lost characters. Using the factory settings, device 3 is intended only for use during configuration and should not be used simultaneously with data traffic on device 1. For special user application done while the BDLCPD is active, use either device 2, or set device 3 to 2400 bauds. 120 20170-202 17 ParagonPD Technical Manual 4. WinRIS program The Windows Radio Installation Software
(WinRIS) program is used to:
Check and troubleshoot ParagonPD. Save an existing configuration. Upload files for field configuring of units
(Requires intervention with technical sup-
port). To run the program, you will need:
- A PC or portable computer running a 32-bit MS-Windows application:
Win ME Win2000 Win NT Win 9x
(For Win 95, if COMCTL32.DLL has been updated to the most recent version and copied to the \windows\system\ directory). Note:
WinRIS does not operate under:
- Win CE (embedded in PocketPC)
16-bit Windows 3.x
- A hard disk.
- An available COM port.
- A serial mouse, with its own driver installed is strongly recommend however most ac-
tions can also be done using keyboard command 4.1 Operation This support program can be run in MS-
Windows mode. DO NOT have more than one copy of this pro-
gram loaded at any given time in separate win-
dows. Doing so creates COM port sharing con-
flicts and failure to run the program alone re-
sults in unexpected transmissions. Only left mouse button operation is supported. Any command or selection shown in gray is ei-
ther unavailable or is awaiting another action before activating. Help in the program is available at all points by pressing the F1 key. If a subject is highlighted, the help displayed will be context sensitive. 4.2 To connect and start WinRIS GeminiPDs and ParagonPDs share a common WinRIS program available on diskette, Datara-
dio p/n 980 03392-00n. Refer to the WinRIS Readme.txt file for details on how to set the MS-Windows environment, and how to connect, install and run this program. In summary, before starting the WinRIS when running MS-Windows, click on Start, then on
"Run". Type the relevant path and variables on the command line (or select by browsing) lead-
ing to:
WinRIS.EXE COM[x], [speed],8,n,1
(where x is the PC COM port to be used) Of course, the executable command may be used alone without any variable added. Click on OK. It is also possible to create a PC desktop short-
cut icon for WinRIS:
Start by right clicking anywhere on the desktop, Select New, Select Shortcut and type the path as detailed above directly on the command line (with or without variables). Click Next, Type in an applicable name for the shortcut icon, Click Next Select an icon (your choice) and Click on Finish. Command line settings override the environment variable, if any. 120 20170-202 18 ParagonPD Technical Manual Figure 16 - WinRIS main screen 4.3 Window This program uses one main display screen only.

cel to exit back to the main screen). When connection is established, all test buttons and fields valid for the product identified are activated. The Station Reset button is also pressed as a last step after doing a Put From. The Station Reset button causes downloaded parameters from a file or diskette to take effect in the connected unit. Pressing Station Reset is not required after do-
ing any Comments or Password configuration change as these have their own Put Comments and Put Password buttons. Station Reset does not break the connection. 4.4.2 Configuration to a file Saving the units configuration to a file allows the user to:
120 20170-202 20 ParagonPD Technical Manual Subsequently restore the configuration. Safeguard a copy as documentation of the configuration. Note: The configuration and status files are ASCII files and may be e-mailed or faxed to technical support when requested to do so. Warning:
Do not make any changes to these files. Any changes made to the configurations MUST be done at factory or by Dataradio system engi-
neering. Get button 4.4.2.1 On the menu bar, select File, then the Get command or press the Get button on the Toolbar to:
Establish linking Download and automatically save the con-
nected units configuration setting to a file named with the unit' serial number: The WinRIS status bar will then report All pa-
rameters are successfully retrieved and saved in file [unit' s/n].BP2. Any previous configuration in the program is overwritten. If you do not wish to overwrite an existing con-
figuration or prefer to name the file yourself, use the Get As button. Get As button 4.4.2.2 After communication is established using the Connect button, press the Get As button to:
Open the File, Save As window with the ASCII file *.bp2 (already selected). Save the connected BDLCPDs operating characteris-
tics (configuration setting) to a file, direc-
tory or drive of your choice. The program will ask before overwriting an existing file. Status bar reports All parameters are suc-
in [file-
cessfully retrieved and saved name]. 4.4.3 Configuration from a File Loading a configuration from a file to a unit is useful to:
Restore the operating characteristics of a unit (Requires intervention with technical support.) Carry out field updates using Dataradio system engineering supplied diskette(s). Warning:
Do not make any changes to these files. Any changes made to the configurations MUST be done at factory or by Dataradio system engi-
neering. Put From button 4.4.3.1 1- On the menu bar, select File, then the Put From command or press the Put From button on the Toolbar. 2- In the Open window, locate the drive, di-
rectory and file name of the relevant file. This may be a configuration saved ear-
lier from a unit. It can also be from a Dataradio (factory or system engineering) diskette. 4- Select the appropriate file 5- Press the OK button. is The status bar reports: [filename]
downloading to 30 seconds later displays: All parameters are saved. Apply Station Reset to take effect!
into unit and up 6- Press the Station Reset button. See section 4.4.1 for details. 4.4.4 Special Functions The following WinRIS fields and buttons are used to gather specific information concerning the connected unit:
Banner field Comments field and Put Comments button Password and Put Password button 120 20170-202 21 ParagonPD Technical Manual Banner Field 4.4.4.1 This field displays a string made up of the serial number of the connected unit followed by the firmwares used and their version number. Format is:
[serial number]:firmware 1 name, its version #, firmware 2 name, its version #. The serial number portion uniquely identifies the unit. It is a variable length, maximum eight-
character alphabetic string assigned at the time of manufacture. It is identical to the serial num-
ber printed on the label of the unit. This number cannot be changed and is used as part of the on-
air protocol. ParagonPD's firmwares reside in flash EPROM and are designed to allow field upgrades. When contacting your supplier, give the full banner string and the version of the WinRIS used. You will find the version number by se-
lecting the Help menu option, then About WinRIS command or pressing the About button on the Toolbar. The Banner field is blank prior to doing a
"Get", "Get As" or "Put From". Comments 4.4.4.2 1- Type comments directly in the Comments field. These can be text up to 24 characters. Use this field to enter user-convenient de-
scription(s) location, etc).
(customer name, 2- Press the button Put Comments to make the entry permanent. This field may be left blank. On subsequent Get, Get As or Put From, this field displays entered comments. If no comment was entered, the field will remain blank. Password 4.4.4.3 The password feature is useful where two (or more) fleets share the same radio channel. Mo-
biles without the proper password would still receive the message but the contents would not be intelligible. 1- Type your password directly in the Pass-
word field. It is a string of 32 hexadecimal characters (exactly). 2- Press the button Put Password to make the entry permanent. This field may be left blank. On subsequent Get, Get As or Put From, this field displays entered comments. If no comment was entered, the field will remain blank. Password information is NOT retrieved and saved to a file, along with the configuration. Clearing a Password is done by entering 32 zeros. The Dataradio supplied password algorithm is designed to thwart the casual observer only. It provides a limited form of data privacy. There-
fore, if your security requirements are high, Dataradio urges you to use external encryption technology such as Data Encryption Standard
(DES) in the Host and Mobiles computers. 4.4.5 Test Functions The following WinRIS functions and buttons are used to carry out testing or trouble-shooting on a connected unit:
DSR signal is High indicator CTS signal is High indicator TXON (Modulated) TXON (Unmodulated) Ping Address and Ping button While a button is in-use for test transmissions, all others are inoperative. DSR signal is High indicator 4.4.5.1 The Data Set Ready (DSR) indicator light, located on the button bar (leftmost), is an RS-
232 protocol port indication. When lit, it indi-
cates proper connection and that the value is 120 20170-202 22 ParagonPD Technical Manual High. The DMP protocol used requires that DSR be normally asserted. CTS signal is High indicator 4.4.5.2 The Clear-to-Send (CTS) indicator light, lo-
cated on the button bar (second indicator from the left), is an RS-232 protocol port indication. When lit, it indicates proper connection and that the value is High. The DMP protocol used re-
quires that CTS be normally asserted. Channel Selection 4.4.5.3 ParagonPD uses its default radio channel. No channel selection being available, all channels are grayed-out and the Show All Channel Fre-
quencies button is disabled. TXON Tests 4.4.5.4 TXON test functions are selected by choosing Test from the file menu, then Modulated or UnModulated command or by pressing the relevant button on the Toolbar. Unmodulated Carrier 4.4.5.4.1 Unmodulated carrier gives a clear carrier and is frequently used for checking:
Frequency error Forward and reverse power Press the TXON (Unmodulated) button to transmit an unmodulated 20-seconds test signal on the channel selected or until the button is pressed again. The functions of all the other buttons are inop-
erative during test transmissions. Power check:
1- Connect an in-line power meter between the radio and the antenna. Measure the forward (nominal 40W for UHF model and 35W for 800MHz model) and re-
flected power levels by powering TX ON (<5%
of forward power or as specified by System Eng.). Modulated Carrier 4.4.5.4.2 Test transmission generates a carrier modulated with 1kHz sinewave, at deviation level that de-
pends on model and network speed as shown in Table 8. This function is frequently used for checking frequency deviation. Press the TXON (Modulated) button to begin transmitting a 20-seconds modulated test signal on the channel or until the button is pressed again. The functions of all the other buttons are inop-
erative during test transmissions. Table 8 Carrier deviations for Tone or Data Modulation Network Speed

- Numerically, the valid address range is 1-126.
- As an Alpha-Mapped-Nibble (AMN) address, consisting of upper case letters in the range A-P. The valid address range is A to GN.
- The base address is usually: 1.
- The program may display one of the following messages on the status bar:
- For ParagonPD product:
Ping address is not in AMN or number format or
- For GeminiPD product:
Ping address is not in the range A GN The left area of the status bar describes actions of menu items as you navigate using the direc-
tional arrows. This area also shows messages describing actions of toolbar buttons as you de-
press them, before releasing them. If after viewing the description of the toolbar button command you wish not to execute the command, then release the mouse button while the pointer is off the toolbar button. Warning and Caution messages appear in pop-
up sub-windows. To close these message boxes, press the ESC key. Three boxes on the right of the status bar indi-
cate which of the following keys is latched down:
Indicator Description CAP The Caps Lock key is latched down. NUM The Num Lock key is latched down. SCRL The Scroll Lock key is latched down. Table 9 - Key latch indications
In either case, check that the address entered is within the acceptable range, is of a valid format and correctly typed. 2- Press the Ping button to start ping testing. The time remaining to test transmit is dis-
played on the status bar. 3- The program sends a test query and contin-
ues transmitting pings at brief intervals. As soon as a Ping test signal is returned from the address selected, the status bar displays:
Ping Successful and pinging stops. If no ping signal is received after 60 seconds, ping testing stops and the status bar displays Ping Failed. 4.4.6 Status Bar The Status Bar is located along the bottom edge of the WinRIS window. To display or hide the bar, check or uncheck the command in the View menu. 120 20170-202 24 ParagonPD Technical Manual 5. Testing and Trouble-
5.2 Recommended Checks Shooting The checks described below should be done at time of installation, annual intervals or when-
ever deterioration in performance is noted. 5.1 Equipment Required In-line watt meter (150W & 10 W ranges) Radio service monitor (IFR-120B with op-
tion 03: 30KHz IF filter or equivalent). RG-214 or RG-223 cable with N-Type male connector to connect ParagonPD to the service monitor. Important note: Before proceeding make sure that the service monitor has been calibrated recently and has warmed up for at least the time specified by its manufacturer. Some reported frequency and deviation prob-
lems have actually been erroneous indications from service monitors that have not adequately warmed up. This is particularly likely when field service is done during winter months.

1. Remove the receiver (T885) module from the ParagonPD rack frame 2. Remove the receiver top cover (nearest the handle). 3. Connect the ParagonPD Extender Rail kit between the RX module and the empty chassis receiver slot. 4. Set the multimeter to read DC Volts. 5. Apply power to the ParagonPD. 6.2.2.2 Synthesizer Alignment Single channel: Connect the multimeter to the long lead of L1 in the VCO (this measures the synthesizer loop voltage). Tune VCO trimmer C6 for a synthesizer loop voltage of 7V (working range is between 3V to 10V). Multiple channels: Select the middle channel via the EPROM PCB DIP switch. Adjust the VCO loop to 7V. All channels should lie within the upper and lower limits of 10V and 3V respectively. 6.2.2.3 Front-End Alignment 1) IFR COM120B settings:
a) Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R output and the receiver antenna connector. b) Select the generator mode (GEN button) and set to the main receiver channel fre-
quency c) Select and turnon GEN2 d) Set the FM Deviation to 3kHz (full channel) or 1.5kHz (half channel) using 1 kHz sine e) Select SINAD meter 2) Monitor the SINAD by connecting an X1 scope probe to the Demod O/P test point (close to PL103 in the first section from the module front panel) or on the relevant backplane board at SK1 pin 6 (see Figure 30 for test point location). 3) Adjust the helical resonators #H1 to #H3 for best SINAD. 4) Continually decrease the RF level to reach 12dB SINAD, then re-do steps 3) and 4) again. (minimum requirement to reach is 12 dB SINAD for 110 dBm) 5) Perform the SINAD linearity tests described in the next paragraphs below. If it fails to pass the requirement, contact your Dataradio technical support. 120 20170-202 34 ParagonPD Technical Manual WARNING: Do not attempt to re-tune the IF stages (i.e. L312 to L318). These adjustments do not need to be re-adjusted after frequency re-
programming. Touching these coils will have a direct impact on the DSP mo-
dem coefficient settings and may significantly reduce the radio performances over data. 6.2.2.4 SINAD and Linearity Check 1. Apply the following settings to the IFR:
- Generator mode, Output T/R
IFR TX frequency to match the main radio RX frequency Filter set to wide band (no audio filter) Select Gen2 (Modulating tone fixed to 1KHz). All other Gen must be off, except for wideband. Set deviation to 3.0KHz for full channel or 1.5KHz for half channel radios.
2. Lower the RF level to get a 12dB SINAD reading. Level must be better than -110dBm
(including cable loss). 3. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) above the main radio RX frequency, record the SINAD reading. It should remain within 1.5dB from the on frequency SINAD reading. 4. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) below the main radio RX frequency, record the SINAD reading. It should remain within 1.5dB from the on-frequency SINAD reading. Note:
If one of the above requirements is not met, try to re-tune the front-end. If it is still failed, contact your Dataradio technical support. 6.2.2.5 RSSI Adjustment 1. Apply an on-channel signal from the RF generator at a level of -110dBm modulated by a 1 kHz tone at a deviation of 3kHz (full channel) or 1.5kHz (half channel). 2. Adjust RV301 (RSSI level) to give 2.0V RSSI output when measured with a multimeter at SK301 pin 2 or on the relevant backplane board at SK1 pin 5 (see Figure 30 for test point lo-
cation). 3. Vary the RF level and check the RSSI output voltage (Figure 28):
1) At 120 dBm: 1.2 VDC (+0.20 0.45VDC) 2) At 90 dBm: 4.0 VDC (+0.20 0.20 VDC) 3) At 80dBm: 5.0 VDC (+0.20 0.35VDC) If the requirement cannot be reached, contact your Dataradio technical support. 120 20170-202 35 ParagonPD Technical Manual 6.2.3 Exciter Module (T881) Note 1: Refer to Figure 22 on page 40 for locating tuning controls. Note 2: When the synthesizer is unlocked, the front panel green LED called "Supply" will be flashing showing that it needs to be re-tuned. 6.2.3.1 Initial Setup 1. Shut down power to the base station 2. Prepare the multimeter to read DC Volts. 3. Remove the exciter (T881) module from the base station rack frame 4. Remove the exciter top cover (nearest the handle). 5. Connect the ParagonPD Extender Rail kit between the exciter module and the empty chassis exciter slot. 6. Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R out-
put and the exciter antenna connector. 7. Apply power to the base station 6.2.3.2 Synthesizer Alignment Single channel: Connect the multimeter to the long lead of L1 in the VCO (this measures the synthesizer loop voltage). Tune VCO trimmer C6 for a synthesizer loop voltage of 7VDC. Multiple channels: Adjust the VCO loop to 7V using the middle frequency channel. All channels should lie within the upper and lower limits of 10V and 3V respectively. Note: Normally, the fast TX key option is installed and the synthesizer is always ener-
gized. Where that option was not fitted, key the transmitter by pressing the front panel Carrier button to make the above adjustment possible. 6.2.3.3 TX Frequency Error Adjustment 1. Apply the following settings to the IFR:
- Receiver mode
- Zoom the RF Error window: select 10Khz range IFR RX frequency to match the main radio TX frequency IF Filter (BW) set to 30KHz 2. Key the transmitter by pressing the front panel TX-key button and measure the carrier output frequency. It should be within 300 Hz. If it is not, adjust the TCXO to trim to meet the requirement, preferably within 100Hz. 120 20170-202 36 ParagonPD Technical Manual 6.2.3.4 Low Frequency Balance Adjustment 1. Apply the following settings to the IFR:
Receiver mode and Oscilloscope display (Source: Demod Out Connector). Zoom the Deviation window: select 10kHz Range and DC coupling. IFR RX frequency to match the radio transmit frequency IF Filter set to 30KHz 2. Select the active or, the lowest (in the case of multi-channel base) frequency channel (via dip switch) 3. Transmit a square wave by pressing the BDLCPDs PF1 button and following the proce-
dure outlined in section 3.2.1.1.2.2. Adjust RV-105 (REF MOD) close to the microphone connector, for best wave shape; no damping, no overshoot. Record the deviation read. 4. If transmission has not ended by itself, press PF1 again to stop it. For single-channel unit, proceed to step 8. 5. For multi-channel unit, select the highest frequency channel. Transmit a square wave by pressing the BDLCPDs PF1 button and following the procedure outlined in section 3.2.1.1.2.2. Record deviation again. 6. The difference in deviation between the two channels should be less than 300 Hz. If not, re-adjust RV105 to "average" the square wave shape on both channels until the spec is met. 7. To confirm the adjustment, select the active, or the lowest frequency channel. Compare 1000 Hz sine wave adjust tone and the deviation produced between:
- Random data The difference should be lower than 300 Hz. For multi-channel unit, repeat this step on the highest frequency channel. 8. Select the active channel. Transmit a TX ON (Modulated) adjustment tone by pressing the BDLCPDs PF1 button and following the procedure outlined in section 3.2.1.1.2.2. Make sure that deviation level read on the IFR correspond to model and bit rate in use
(see Table 8 Carrier deviations for Tone or Data Modulation). Re-adjust deviation as necessary referring to Checklist B - page 27. 6.2.3.5 Exciter Power Output 1. Apply the following settings to the IFR:

- Receiver mode, Output T/R
- Connect the coaxial cable from the IFR T/R to the Exciter output connector 2. Key the Exciter by pressing the module PTT button. The output power must be:
800MHz (T881) = 4W 300mW. 3. If 4Watts is not reached, adjust helical #L300 for maximum power output (which should be at least 7W); adjust RV356 down to 4W. 120 20170-202 37 ParagonPD Technical Manual 6.2.4 Power Amplifier Module (T889) 1. Re-install the exciter module into the Paragon rack frame 2. Connect the Exciter module to the Power Amplifier 3. Connect the Power Amplifier output to the IFR T/R connector or to a stand-alone BIRD style power meter, terminated with a 150W dummy load. 6.2.4.1 Power Amplifier Power Out 1. Set RV63 (Power adjustment, access on the front panel) fully clockwise. 2. Key the transmitter from the exciter Carrier button. The power output should exceed 90W. 3. Adjust RV69 (Driver power, access from the left end side) until the output power drops to 90W. 4. Adjust RV63 (Power) to reduce power output to its nominal value (70W) or lower as re-
quired. 5. Cable loss should be included in the reading. 6.2.4.2 Forward Power Alarm Level 1. Power up the T889 and adjust RV63 (Power) so that the output power is at the alarm level required, usually 20% lower than nominal value (e.g. 40W if the PA normally op-
erates at 50W). 2. Adjust RV48 (Forward power Alarm set) so that the forward power alarm LED lights. 3. Adjust RV63 (Power) for the normal operating power level. 6.2.4.3 Reverse Power Alarm Level (Optional) 1. Power up the T889 and adjust RV63 (Power) for the normal operating power level. 2. Place a known mismatch of the required value (e.g. 3:1 VSWR) and adjust RV52 (re-
verse power alarm set) so that the reverse power alarm LED lights. Example: A VSWR of 3:1 can be simulated by connecting an undetermined 3 dB pad to the PA output. This will result in a loss of 6 dB. 120 20170-202 38 ParagonPD Technical Manual FRONT PL103 Demod output RSSI Test point:

To set a default channel via the software, all DIP switches must be set to OFF (i.e. 00000000). When a switch is Off, its binary count is active; when a switch is ON its binary count is in-
active. The various DIP switch combinations of ON or OFF make up a binary total, which identifies the channel number. To select a channel, set the appropriate DIP switch or switches to OFF to make the binary count total the channel number you want. Set all other switches to ON. It is recommended to set both SW1 (RX) and SW2 (TX) to the same settings on both back plane boards. Example: To select channel 5, set the DIP switches as shown below:

1. Remove the receiver (T855 or T835) module from the ParagonPD rack frame 2. Remove the receiver top cover (nearest the handle). 3. Connect the ParagonPD Extender Rail Kit for Series II to the empty chassis receiver slot. 4. Prepare the multimeter to DC Volts. 5. Apply power to the ParagonPD. 120 20170-202 45 ParagonPD Technical Manual 6.4.2.2 Synthesizer Alignment Single channel: Connect the multimeter to the long lead of L1 in the VCO (this measures the synthesizer loop voltage). 1. T855 (UHF) Tune VCO trimmer C6 for a synthesizer loop voltage of 10V DC. 2. T835 (VHF). Tune VCO trimmer CV1 for a synthesizer loop voltage of 9VDC. Multiple channels:
1. T855 (UHF) Adjust the VCO loop to 10V using the middle channel. 2. T835 (VHF) Adjust the VCO loop to 9V using the middle frequency channel. 3. All channels should lie within the upper and lower limits of respectively All channels should lie within the upper and lower limits of 16V and 3V respectively for the T855 and within 13V and 5V for the T835. 6.4.2.3 Front-End Alignment 1. IFR COM120B settings:
a) Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R output and the receiver antenna connector. b) Select the generator mode (GEN button) and set to the main receiver channel fre-
quency c) Select and turnon GEN2 d) Set the FM Deviation to 3kHz (full channel) or 1.5kHz (half channel) using 1KHz sine e) Select SINAD meter f) Use a X1 scope probe connected to SINAD input and monitor the Discriminator O/P on the backplane at SK1 pin 6 (RX-audio1). Alternately, it is also possible to moni-
tor at the receiver TP314 (T855) or at the receiver IC350 pin 7 (T835). 2. Adjust the helical resonators for best SINAD: #FL410 and #FL420 (T855) or L410, L420, L460 and L470 (T835). 3. Continually decrease the RF level to reach 12dB SINAD, then re-do step 2) & 3) again.
(minimum requirement to reach is 12dB SINAD for -110dBm) 4. Perform the SINAD linearity tests described in paragraph 6.4.2.4. If it fails to pass the requirement, contact your Dataradio technical support. WARNING: Do NOT attempt to re-tune the IF stages
(i.e. L310 to L390 for T855, CV318 or L330 to L360 for T835). These adjustments do not need to be re-adjusted after frequency re-
programming. Touching these coils will have a direct impact on the mo-
dem DSP coefficient settings and may reduce significantly the radio per-
formances over data. 6.4.2.4 SINAD and Linearity Check 1. Apply the following settings to the IFR:
a) Generator mode, Output T/R 120 20170-202 46 ParagonPD Technical Manual b) IFR TX frequency to match the main radio RX frequency c) Filter set to wide band (no audio filter) d) Select Gen2 (Modulating tone fixed to 1KHz). All other Gen must be off. e) Set deviation to 3.0KHz for full channel or 1.5KHz for half channel radios. f) Use a X1 scope probe connected to IFR SINAD input and monitor the Discriminator O/P on the backplane at SK1 pin 6 (RX-audio1). Alternately, it is also possible to monitor at the receiver TP314 (T855) or at the receiver IC350 pin 7 (T835) 2. Lower the RF level to get a 12dB SINAD reading. Level must be better than -110dBm
(including cable loss). 3. Offset the IFR TX frequency 2kHz (full channel) or 1kHz (half channel) above the main radio RX frequency, record the SINAD reading. It should remain within 1dB from the on frequency SINAD reading. For T855, use above values, for T835 use 1.5kHz (full chan-
nel) or 0.8kHz (half channel). 4. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) below the main radio RX frequency, record the SINAD reading. It should remain within 1dB from the on-frequency SINAD reading. For T855, use above values, for T835 use 1.5kHz (full channel) or 0.8kHz (half channel). Note: If one of the above requirements is not met, try to re-tune the front-
end. It still failed, contact your Dataradio technical support. 6.4.2.5 RSSI Adjustment (UHF: T855)
- Apply an on-channel signal from the RF generator at a level of -110dBm modulated by a one kHz tone at a deviation of 3kHz (full channel) or 1.5kHz (half channel).
- Adjust RV320 (RSSI level) to give 2.0V RSSI output at SK330 pin 2 or on backplane SK1 pin 5 when measured with a voltmeter (See Figure 30 for test point location).
- Vary the RF level and check the RSSI output voltage ( Figure 28):
1) At 120 dBm: 1.2 VDC (+0.20 0.45VDC) 2) At 90 dBm: 4.0 VDC (+0.20 0.20 VDC) 3) At 80dBm: 5.0 VDC (+0.20 0.35VDC) If the requirement cannot be reached, contact your Dataradio technical support.

ponents. T881 series II will be included in a later release. Note 2: When the synthesizer is unlocked, the front panel green LED called "Supply" will flash indicating that it needs re-tuning. Warning: The LED will also flash when the unit is in setup mode while connected to the PGM800win program. 6.4.3.1 Initial Setup 1. Shut down power to the base station 2. Prepare the multimeter to DC Volts. 3. Remove the exciter (T857 or T837) module from the base station rack frame 4. Remove the exciter top cover (nearest the handle). 5. Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R out-
put and the exciter antenna connector. 6. Connect the ParagonPD Extender Rail Kit to the empty chassis exciter slot. 7. Apply power to the base station 6.4.3.2 Synthesizer Alignment Single channel: Connect the multimeter to the long lead of L1 in the VCO (this measures the synthesizer loop voltage). 1. T857 (UHF) Tune VCO trimmer C6 for a synthesizer loop voltage of 10V DC. 2. T837 (VHF). Tune VCO trimmer CV1 for a synthesizer loop voltage of 9VDC. Multiple channels:
1. T857 (UHF) Adjust the VCO loop to 10V using the middle channel. 2. T837 (VHF) Adjust the VCO loop to 9V using the middle frequency channel. All channels should lie within the upper and lower limits of 16V and 3V respectively for the T857 and within 13V and 5V for the T837. Note:
Normally, the fast TX key option is installed and the synthesizer is always ener-
gized. In the case where that option was not fitted, key the transmitter by pressing the front panel Carrier button to make the above adjustment possible. 6.4.3.3 TX Frequency Error Adjustment 1. Apply the following settings to the IFR:
- Receiver mode
- Zoom the RF Error window: select 10Khz range IFR RX frequency to match the main radio TX frequency IF Filter set to 30KHz 120 20170-202 49 ParagonPD Technical Manual 2. Key the transmitter by pressing the front panel TX-Key button and measure the carrier output frequency. It should be within 300 Hz. If it is not, adjust the TCXO to trim to meet the requirement, preferably within 100Hz. 6.4.3.4 Low-Frequency Balance Adjustment PGM800Win controls this adjustment. Electronic potentiometer (256 step) is used to allow channel adjustment of two-point modulation (Low freq. balance). 1. Apply the following settings to the IFR:
Receiver mode and Oscilloscope display (Source Demod out connector, DC cou-
pled). IFR RX frequency to match the radio transmit frequency IF Filter set to 30KHz Zoom the Deviation window: select 10kHz Range and DC coupling. 2. Select the active or, the lowest (in the case of multi-channel base) frequency channel (via dip switch) 3. Transmit a square wave by pressing the BDLCPDs PF1 button and following the proce-
dure outlined in section 3.2.1.1.2.2. You can also run both programs on the same com-
puter if two serial COM ports are available. 4. Adjust IC220 via PGM800Win reference modulation to obtain the best square wave, no damping, no overshoot. (You can use either the mouse or up and down arrow keys). Record the deviation read. 5. If transmission has not ended by itself, press BDLCPD PF1 to stop it. For single-channel unit, proceed to step 8. 6. For multi-channel unit, select the highest frequency channel. Transmit a square wave by pressing the BDLCPDs PF1 button and following the procedure outlined in section 3.2.1.1.2.2. Record deviation again. 7. The difference in deviation between the two channels should be less than 300Hz. If not, re-adjust IC220 to "average" the square wave shape on both channels until the spec is met. 8. To confirm the adjustment, select the active, or the lowest frequency channel. Compare 1000 Hz sine wave adjust tone and the deviation produced between:
- Random data The difference should be lower than 300 Hz. For multi-channel unit, repeat this step on the highest frequency channel. 8. Select the active channel. Transmit a TX ON (Modulated) adjustment tone by pressing the BDLCPDs PF1 button and following the procedure outlined in section 3.2.1.1.2.2. Make sure that deviation level read on the IFR correspond to model and bit rate in use
(see Table 8 Carrier deviations for Tone or Data Modulation). Re-adjust deviation as necessary referring to the related Checklist (B for ParagonPD - page 27 120 20170-202 50 ParagonPD Technical Manual 6.4.3.5 Exciter Power Output 1. Apply the following settings to the IFR:
IFR RX frequency to match the main radio TX frequency IF Filter set to 30KHz
- Receiver mode, Output T/R
- Select auto range in the Power reading window
- Connect the coaxial cable from the IFR T/R to the Exciter output connector 2. Key the Exciter by pressing the module PTT button. The output power must be:
- VHF (T837) = 800 mW 200mW
- UHF (T857) = 1W 300mW
800 (T881) = 4W 300mW 6.4.4 Power Amplifier Module (T859 or T839)
- Re-install the exciter module into the ParagonPD rack frame
- Connect the Exciter module to the Power Amplifier.
- Connect the Power Amplifier output to the IFR T/R connector or to a stand-alone BIRD style power meter, terminated with a 150W dummy load.
- Forward and reverse power alarm set (control) are identified on the PA cover. 6.4.4.1 Power Amplifier Power Output
- Key the transmitter on the exciter and adjust the PA output for 100W using front panel power control. If power cannot be reached, refer to section 6.4.4.4 for T859 UHF model or to Tait T839 service manual for T839 model. Cable loss should be included in the reading. 6.4.4.2 Forward Power Alarm Level 1. Power up the PA and adjust front panel power control so that the output power is at the alarm level required, usually 20% lower than nominal value (e.g. 40W if the PA nor-
mally operates at 50W). 2. Adjust the forward power alarm set (T859: RV48 or T839: RV101) so that the forward power alarm LED lights. 3. Adjust front panel power control (T859: RV63 or T839: RV109) for the normal operat-
ing power level 6.4.4.3 Reverse Power Alarm Level (Optional) 1. Power up the PA and adjust the front panel power control for the normal operating power level. 2. Place a known mismatch of the required value (e.g. 3:1 VSWR) and adjust the reverse power alarm set (T859: RV52 or T839: RV105) so that the reverse power alarm LED lights. Example:
A VSWR of 3:1 can be simulated by connecting an unterminated 3dB pad to the PA output. This will result in a return loss of 6dB. 120 20170-202 51 ParagonPD Technical Manual 6.4.4.4 Tait T859 (UHF) Standard Tuning Procedure 1. For sets with serial numbers following 217262, set RV69 (driver power level) fully clockwise. 2. For all units, preset the tuning controls as shown in Figure 31 Figure 31 - T859 Tuning Settings 3. Set RV63 (front panel power control) fully clockwise. 4. Key on the exciter (press PTT button). 5. Adjust CV1 for maximum output. 6. Adjust CV8 for maximum output. 7. Adjust CV32 for maximum output. 8. Adjust CV51 and CV57 for maximum output. 9. Adjust CV34 and CV35 for maximum output. 10. Recheck all settings. The power output should exceed 110W. 11. For sets with serial numbers following 217262, adjust RV69 (driver power level) until the output power drops to 110W. 12. For all units, adjust RV63 to reduce the power output to the required level (normally 100W). 6.4.4.5 Tait T859 Tuning for Best Efficiency 1. Insert a Shunt current device (HP 34330A Shunt 30A ) between the power supply red wire and its 13.8Vdc output, then connect the shunt to the multimeter (VDC scale) 2. While transmitting, monitor the current. It should remain under 22A. 3. Retune CV32, CV51 and CV57 towards maximum capacitance to obtain minimum sup-
ply current, but do not exceed a maximum drop of 0.5A per control. 4. Check that the supply current is <22A for 100W output power. Note:
These control settings are normally very close to minimum supply current. If the current is reduced too far, maximum power output will drop and 2f rejection may degrade. 120 20170-202 52 ParagonPD Technical Manual IC 310 SK330 pin 2 Figure 32 - T855 Receiver Tuning Controls Location 120 20170-202 53 ParagonPD Technical Manual TCXO Figure 33 - T857 Exciter Tuning Controls Locations 120 20170-202 54 ParagonPD Technical Manual L410 L420 L1 L460 L47 L330 CV318 L340 RSSI Test Point P207 IC 700 CV1 L350 IC 350 L360 Figure 34 - T835 Receiver Tuning Controls Location 120 20170-202 55 ParagonPD Technical Manual IC700 TCXO L1 CV1 IC220 Figure 35 - T837 Exciter Tuning Controls Location 120 20170-202 56 ParagonPD Technical Manual Appendix 1 - ParagonPD Deviation adjust 1. Using the WinRIS, press TX ON (Modulated) and record deviation level as read on the IFR. 2. Using Windows Notepad, Edit the .bp2 file named with the corresponding BDLCPD serial number (e.g. abcd.bp2). Save as to another file name and keep it in case something goes wrong while changing a parameter. 3. Locate the line labeled Dev0 Par85= and record the value beside the = sign. This is the corresponding parameter value to the deviation read in step 1. 4. Apply the following formula to determine the new parameter value to be set:
(New Par85 value) = [(initial Par85 value) X (target deviation) / (deviation read)] + 2 5. Change the value in the file, Save as using the BDLCPD serial number file name. 6. Run the WinRIS again and do a Put From. From the opened window, select the file that you just made the change to and then press OK 7. Again, check deviation level while pressing TX ON (Modulated). If the level is now correct, press Stationreset to make the change permanent. Otherwise do step 5 again, changing the value entered in the file by 1 or 2 digit(s) up or down, fine-tuning directly the Par85 (DSP deviation) parameter. Do steps 6 and 7 again to confirm acceptance. This last step may have to be repeated once or twice while varying the entered value up or down. If unable to obtain the correct level after editing up and/or down by no more than 2, contact System Engineering. 120 20170-202 57 ParagonPD Technical Manual 7.

If damage has occurred to the equipment during shipment, file a claim with the carrier immedi-
ately. 2.1 Overview The cabinet and rack-mount housing the Para-
gonPDs Radio assembly and the BDLCPD is generally installed in a sheltered facility. Occa-
sionally located adjacent to the nerve center of the users network, it is often located near tower sites or at remote locations where it operates unattended. Furnishings needed include power, cabling and installation of antenna, landline or microwave modem and host PC or portable computer. De-
tails of these are outside the scope of this man-
ual. This manual covers the radio assembly and the BDLCPD that includes the modem. 2.2 Location Be sure to place the ParagonPD in such a way that:
The LEDs can be seen (as an aid in trouble-
shooting) Access to the antenna connector and to the back connectors is possible without remov-
ing the unit Sufficient air may flow around the unit to provide adequate cooling. 2.3 Electrical Standard 120 VAC electrical power is required. It should be capable of providing at least 10A to power ParagonPD (<6A) and ancillary equip-
ment. 120 20170-201 4 ParagonPD Technical Manual Air Flow Receiv er E xc ellence in R adio C ommunic at ions Receiv er Exciter Pow er Amp lifi er S peaker Panel Gating Sensitivi ty Gate Line Le vel Supply Monitor Volume O ff O n Monitor Mute Supply L ow Forw ard P ower Hi gh Re ver se Power Pow er Gating Sensitivi ty Gate Car ri er O n Line Le vel Supply Supply Line Sensitivi ty Microphone Monitor Volume O ff O n Monitor Mute SP EAK ER SELE CT SWI TCH R X1 R X2 OFF p rogra mmin g po rt Dual Power Supply Module OL Stby On Power OL Stby On Power Figure 1 Typical radio and power supply assemblies, front view T800 II Slimline CM FR FT RD TD 1 3 2 RS-232 CK LM LF RM UF ALARMS PF1 RES ET S-3 CS T X RX RF Figure 2 - BDLCPD, front view 120 20170-201 5 ParagonPD Technical Manual REAR VIEW Air Flow FAN _ +

cally rack-mounted right below the main assem-
bly radio chassis. The T800 is made up of two separate power supply units joined in a single chassis:
A T807 using convection cooling is rated up to 15A at 13.8VDC. It supplies all the radio modules other than the Power Amplifier. A T808 using convection and fan cooling is rated up to 25A at 13.8VDC. It supplies only the Power Amplifier module. Normally used at room ambient temperatures, they can operate within specifications over a range of 10 to +60 C. Note: Internal over-temperature protection shuts down the main transformer above 105 degrees Celsius. Both power supply modules are internally con-
nected to ground via their individual, rear-
connected, seven-foot standard 120 VAC power cords. Nevertheless, each requires a separate secure electrical ground connection. Individual grounding tabs are provided next to the power connectors. Similarly, the Radio Assembly chassis requires a secure ground connection. A threaded grounding binding post fitted with a knurled binding-nut is provided on the chassis next to DC input 2. Separate grounding leads with appropriate con-
nectors are supplied (either in the courtesy small-parts kit or with one end fastened to the equipment. A- For each of the power supply modules:
1. Fit one end of the grounding leads push-on connector onto the grounding tab. B- For the Radio Assembly chassis:
1. Install the grounding leads lug over the binding post and firmly hand-
tighten the binding-nut. For both A and B 2. Fit the slotted connector (on the other end of each of the grounding connector) under a conveniently located screw on the rack frame or other support surface. Scrape away paint if needed to ensure clean contact. 3. Apply anti-corrosion compound where paint scraping was done. 4. Ensure by testing continuity that a se-
cure electrical and mechanical connec-
tion is achieved. If a DC rail (0V) is installed as part of the sys-
tem, the grounding leads may alternatively be fitted to the rail terminal. Caution:
Improper grounding between power supply case and rack frame may result in harmful voltage potentials and/or miscellaneous power supply switching noise problems in both receivers and transmitter. Press both red power buttons located on the front of the module to have complete power distribution to the Radio assembly. The power supply front panel LEDs indications are:

nect the main power cords. Over voltage For LEDs descriptions, see section 3.2.1.2 The Radio assembly is fused at the rear of the chassis:
Fuse 1 is a 32-volt MDL 10A (Cartridge 6x32mm, slow-blow) Fuse 2 is a 32-volt MDL 30A (Cartridge 6x32mm, slow blow) 120 20170-201 7 ParagonPD Technical Manual 2.3.2 BDLCPD assembly Power The BDLCPD assembly uses a standard 120 VAC power cord. Plug this cord to the rear power outlet shown in Figure 6. To check or install a fuse:
1. Open the slide-out fuse drawer located be-
low the power connector. 2. Use a fine bladed screwdriver or a knife blade and gently pry open. 3. Hold the fuse support in one hand and with the other, lift the center plastic retainer until it releases the fuse sliding base. 4. Replace or install a 250V, 2A fuse. 5. To complete the procedure, push the sliding fuse base until it snaps under the retainer. 6. Re-insert the fuse drawer in its housing and push until it is fully seated and closed. When ready to apply power, use the ON-OFF toggle power switch adjacent to the power con-
nector. ON-OFF Switch 120VAC Connector Fuse Slide-out Drawer Use only with a 250 V fuse Employer uniquement av ec un fusible de 250 V Figure 5 - BDLCPDs rear connection, switch and fuse 2.4 Antenna 2.4.1 Overview ParagonPD commonly uses three antennas (one transmit and two receive) unless a duplexer is used with one of the receive antennas; then only two antennas would be needed. They should be mounted according to any guidelines supplied with the antennas. For antennas placement and spacing, consult System Engineering. 2.4.2 Cabling and Connection 1- Route good quality 50-ohm double-shielded coaxial cable(s) (e.g. RG-214 or Heliax) from the selected antenna position(s) to the ParagonPD Radio assembly. 2- Terminate the RX-1 and RX-2 cable ends at the Receiver modules rear position with an N-type connector. 3- Similarly, terminate the TX cable end at the Power Amps module rear position with an N-type connector. Caution:
When terminating RF cables use brand-name crimping tools
(such as AMP, Jensen, Crimp-
Master, etc) of the correct size for the cable and type of connector used. Common pliers are NOT ac-
ceptable. 2.5 Completing the physical Installation. ParagonPD products are factory-configured to users requirements and are shipped ready to run. After new installations:
Re-check that all connections are secure on radio and BDLCPD assemblies (antennas, PC, power cords etc.) Check that fuses are inserted. Turn both BDLCPD and radio power ON. You are now ready to check for normal opera-
tion and to run the Windows Radio Installation Software (WinRIS) program for testing or trou-
ble-shooting. Any change(s) to the settings must be done via files saved on diskette and loaded into the unit using the WinRIS program. 120 20170-201 8 ParagonPD Technical Manual 2.6 Checking out Normal Operation 1- Check that power is applied. 2- Check Radio assembly lights for proper op-
eration as per section 3.1.1 3- Check for proper operation of the BDLCPDs LEDs as per section 3.2.1.2. 4- Using the WinRIS program (described in section 4), and an in-line wattmeter, check the forward & reflected power to confirm antenna installations. 5- Using the WinRIS, check the RF link with a mobile station that can be heard, by using the WinRIS Ping feature. See section 4.4.5.5 If user application and a mobile station are available, test the installation by going through a normal sequence of transmitting and receiving messages. 3. Operating Description 3.1 Radio Assembly The Radio assembly component of each Paragon product is made up of high performance synthe-
sized radio base station designed for single op-
eration. Referring to Figure 1 on page 5, the Ra-
dio Assemblys modules are commonly installed in a standard, 19-inch wide rack frame. 3.1.1 Front panels The complement of modules is identical for:

RJ11 connector Mirrors the one on the front of the Speaker panel (series connected 120 20170-201 11 ParagonPD Technical Manual to both backplanes). Used for programming the Radio Assembly whenever the speaker panel has been removed. This feature is exclusive to the Series II model. Series I models programming is done externally via EPROMs. DB-25M plug at PL1 (one side of the Y cable on each PCB) used to supply the re-
ceive signal to the BDLCPDs single EXT.RADIO/TEST DB-25F plug. Two channel-select DIP switches (SW1 and SW2) This feature is exclusive to the Series II model. Cooling fan driver CN2 located on back-
plane connects to the horizontally-mounted fan on top of the Radio assembly and acti-
vated by BDLCs PTT signal. Coaxial relay driver not used. 3.2 BDLCPD The rack-mounted BDLCPD is housed in a steel case. It has no user serviceable parts. Units configuration flash memory
(EEPROM). is stored in 3.2.1 BDLCPD Front panel Referring to Figure 2, the front panel of the BDLCPD has two cutouts across its length. A- The left cutout groups the units type label and ten LED indicators:
The S3 label designates the BDLCPD as a three Serial-port model
(Ports 4 and 5 are reserved for future use) The RF group of 3 LEDs The RS-232 group of 5 LEDs A single CK LED The ALARMS group of 4 LEDs B- The right cutout groups two tactile (mem-
brane) switches (PF1 and RESET). Front Switches 3.2.1.1 Referring to Figure 11, the BDLCPD uses two membrane-type switches labeled:
RESET PF 1 These switches indicate contact by emitting a short BEEP tone when pressed. PF1 RESET Figure 11 - BDLCPD membrane switches Reset 3.2.1.1.1 Pressing Reset produces the same result as pow-
ering OFF and ON again. It restarts the micro-
processor, the peripherals and invokes the on-
board diagnostics. BDLCPDs radio modules internal flash-memories are read and their val-
ues are loaded in system SRAM CPU flash-
memory. Normally, pressing Reset results in one short BEEP tone followed by all LEDs coming ON for about four seconds. Then, the LEDs flash in a ripple pattern for close to two seconds indi-
cating diagnostics are in progress. At the end of this period, all LEDs should be OFF except CK that should flash about six to eight times per second. Expect an additional two seconds delay for CK to start flashing and the UF indicator to come ON if the radio assembly is not connected or not powered (see section 3.2.1.2.4 for Alarm de-
tails). PF 1 3.2.1.1.2 PF 1 is a multi-function switch:
It clears LED error indications It initiates test transmissions It sets the function of the RS-232 LEDs 120 20170-201 12 ParagonPD Technical Manual Clearing Errors 3.2.1.1.2.1 Major and minor error LED indications remain lit on the front panel until:
The unit is RESET The unit is powered OFF and ON again PF 1 is pressed The PF 1 switch can be pressed at any time to clear an error display without affecting normal operations. Test Transmissions 3.2.1.1.2.2 To select a pattern and begin transmission, start by pressing and holding PF1. It beeps once, all five RS232 LEDs light; listen for a second beep followed by a third beep. After two seconds, the unit beeps and goes in TX Select mode with only the three rightmost RS-232 LEDs now used as selection indicators. Only release PF1 after the third beep. Following release:
Start of selection must be made within two seconds. If not, the unit will default to pat-
tern one and start test transmitting. PF1 may be pressed more than once. The number of times it is pressed determines the type of pattern that will be transmitted ac-
cording to Table 3. Each pressing of PF1 extends the two-
second timer. The three rightmost RS-232 LEDs display are used to indicate TX mode selection as shown in Table 2. Table 2- TX mode selection LEDs indications TX pattern selected Binary TX mode LED indications FT LED RD LED TD LED 1 2 3 4 5 6 7 Off Off Off On On On On Off On On Off Off On On On Off On Off On Off On Once the type of transmission is selected, stop pressing PF1, allow the two-seconds timer to run down. Automatically, the BDLCPD turns its transmitter ON, sends the selected test pattern for 55 seconds and turns its transmitter OFF. The TX LED in the RF group of indicators lights in red while test transmitting. Pressing PF1 while the 55 seconds test is in progress stops the test. At the end of test transmission, BDLCPD opera-
tion returns to normal and the RX LED lights in green (monitoring normal transmitter activity). Table 3 - Test Transmissions

For DGFSK models, a dotting pattern consists of an alternating series of bits. For the SRRC4FSK models, only the lowest-level symbols modulation is used. The square wave is used to check transmitter low frequency balance. The 1000 Hz sine can be used for transmitter distor-
tion measurements. Pattern 6 produces a transmission of approximately 55 seconds followed by about 55 seconds of silence. Initial transmission in a sequence may be shorter than 55 seconds. TX LED stays steadily red for dura-
tion of the test. Press PF1 to terminate beacon mode. 120 20170-201 13 ParagonPD Technical Manual 3.2.1.1.2.3 RS-232 LED Function Selection The PF 1 button is used to select the RS-232 display mode as follows:
If pressed ONCE (do not hold pressed):
- Clears Alarm indications
- CK LED stops flashing for 2 seconds
- During this time, one or all of the RS-232 numbered LEDs (see Figure 13) will light. If one LED lights, it denotes the port to which the subsequent display applies. If all numbered LEDs light, it denotes that the normal 3-port display mode is active. The selected display remains active un-
til manually changed or until RESET is pressed or until power up. Table 4 - RS-232 LED Function Selection Sequence RS-232 LED Function Selection Sequence ALL 1 2 3 4 (reserved) 5 (reserved) ALL 1 2 3 4 (reserved) 5 (reserved) TX LED in RF group lights with any and all transmission TX LED in RF group only lights with an ACK or DATA transmission If, during the 2 seconds period that CK is not flashing, PF 1 is pressed a second time, the LED functions will advance one step from top to bottom through the available options in the order shown in Table 4. PF 1 may be pressed repeatedly during the 2 second period (extended with each press) to advance to the desired numbered LED function option. Once the desired RS-232 LED function is se-
lected, stop pressing PF1, allow the two-seconds timer to run down. The BDLCPD returns to nor-
mal operation using the newly selected display. 3.2.1.2 LEDs and Indications LEDs are used to indicate the operation status of the BDLCPD. Although capable of displaying three colors, only the green and red colors are used for the BDLCPD. They are grouped by their function:
RF Group, displays radio channel status in green RS-232 Group, displays serial port status in green except the TX LED that also uses red ALARM Group, displays fault status in red Radio Network Indicators 3.2.1.2.1 The Radio Network LEDs are useful when trou-
bleshooting as an indication of network activity. It can help isolate transmission problems. C S R X T X R F Figure 12 - RF indicators CS RX TX Carrier Sense - Steady light indicates that an incoming radio data signal is being detected by the DSP modem. CS signal is not user-adjustable. Receive Data Flashing light indicates unit is internally receiving data from the radio network. Transmitter ON blinks green indicates
(depending on display mode selected):
That a data packet or ACK (packet acknowledgment) is being trans-
mitted. That an idle packet, data packet or ACK is being sent. Test transmis-
sion display is done in red. RS-232 Port Indicators 3.2.1.2.2 The RS-232 LEDs normally indicate port activ-
ity on the port selected. See section 3.2.1.1.2.3 above for instructions for selecting display mode. 120 20170-201 14 ParagonPD Technical Manual C M 1 F R F T R D 3 2 R S -232 T D Figure 13 - RS-232 Port LED indicators FR CM Command Mode - LED lights and re-
mains lit while the selected port is ac-
cessing the Command Processor. It lights ON and OFF while being config-
ured. Flow Control on Receive - the BDLCPD has received a flow control signal from the device connected to it. When it lights, BDLCPD has stopped sending data to the DTE. When LED goes out, the port terminal is again ready to re-
ceive data. Flow Control on Transmit - the BDLCPD has sent a flow control signal to the DTE asking it to stop sending data. The LED remains lit as long as the terminal is being held off. FT RD TD Receive Data - when lit, it shows that the Receive Data pin 3 on the RS-232 interface connector is active. Since all BDLCPD are configured as DCE, it means that the DTE is receiving data from the BDLCPD. Transmit Data - shows the status of Transmit Data pin 2 of the RS-232 in-
terface. When lit, the DTE is sending data to the BDLCPD. 3.2.1.2.3 CK Check and Power Check:
Normally flashing rapidly (about 6 cps), indicates microprocessors are working correctly and power is applied. Not flashing indicates unit is not func-
tioning. Blinking slowly (1 cps), indicates the parameters contents of the flash memory have been corrupted. The unit automati-
cally loads its set of factory default pa-
rameters and starts beeping at 20 sec-
onds intervals. May also initialization has occurred indicate DSP-modem re-
Alarm Indicators 3.2.1.2.4 All alarm conditions will cause the BDLCPD to light one or more of the LED indicators. LEDs remain ON when lit until cleared by either pressing PF 1 (without affecting operation of the unit) or RESET (cycling unit OFF and ON). LM RM LF UF ALARMS Figure 14 - ALARMS LED indicators LM Local Minor Alarm - when lit, indicates the presence of any of the following mi-
nor faults:
- Parity, framing or overrun error at any RS-232 port.
- Out of buffers. No memory available to accept data from a local terminal de-
vice. Usually denotes a flow control problem.
- Flash memory error. At power-up or reset, the unit detected a change in non-
volatile memory. RM Remote Minor Alarm - when lit, indi-
cates any of the Local Minor Alarm listed above have taken place at the re-
mote end of the link (i.e. the mobile the local base station is currently communi-
cating with). It will also light when a protocol error has been detected on the network. In a network using the Host Link Ac-
tive (MSC) feature, the RM LED, flashing in-sync with the CK LED, indi-
down. cates link that the is 120 20170-201 15 ParagonPD Technical Manual UF LF Link Failure - when lit, indi-
cates that the base station fails to re-
ceive an ACK for a packet sent and for all subsequent retries. Some data has possibly been lost. LF is not functional if all active ports are set to NAR mode. Link fails are inevitable during normal operation (mobiles temporarily out of range, in a tunnel, parked in a dead spot, etc.). A lit LF LED is not normally cause for concern. Unit Failure - when lit, the unit requires attention:
- The BDLCPD is not operable;
It may indicate detection of a system software error trap.
- The BDLCPD is operable;
Indicates that on power-up, invalid data was detected in the serial EEPROM chip (located in the radio modules). It may also indicate that connection to the radio modules is incorrect or that radio power is not applied. The LM, RM and UF alarms also sound a beep when a fault occurs. The LF alarm is silent. 3.2.2 BDLCPD Rear panel Referring to Figure 4, the rear panel of the BDLCPD has the following set of chassis con-
nectors:
Four DE-9F connectors:
DEV2 - usually connected to Datara-
dios WinRIS program (DMP/Setup 19200). Can also be used with special users application such as telephone modem. Note: connection to a tele-

Using the factory settings, device 3 is intended only for use during configuration and should not be used simultaneously with data traffic on device 1. For special user application done while the BDLCPD is active, use either device 2, or set device 3 to 2400 bauds. 120 20170-201 17 ParagonPD Technical Manual 4. WinRIS program The Windows Radio Installation Software
(WinRIS) program is used to:
Check and troubleshoot ParagonPD. Save an existing configuration. Upload files for field configuring of units
(Requires intervention with technical sup-
port). To run the program, you will need:
- A PC or portable computer running a 32-bit MS-Windows application:
Win ME Win2000 Win NT Win 9x
(For Win 95, if COMCTL32.DLL has been updated to the most recent version and copied to the \windows\system\ directory). Note:
WinRIS does not operate under:
- Win CE (embedded in PocketPC)
16-bit Windows 3.x
- A hard disk.
- An available COM port.
- A serial mouse, with its own driver installed is strongly recommend however most ac-
tions can also be done using keyboard command 4.1 Operation This support program can be run in MS-
Windows mode. DO NOT have more than one copy of this pro-
gram loaded at any given time in separate win-
dows. Doing so creates COM port sharing con-
flicts and failure to run the program alone re-
sults in unexpected transmissions. Only left mouse button operation is supported. Any command or selection shown in gray is ei-
ther unavailable or is awaiting another action before activating. Help in the program is available at all points by pressing the F1 key. If a subject is highlighted, the help displayed will be context sensitive. 4.2 To connect and start WinRIS GeminiPDs and ParagonPDs share a common WinRIS program available on diskette, Datara-
dio p/n 980 03392-00n. Refer to the WinRIS Readme.txt file for details on how to set the MS-Windows environment, and how to connect, install and run this program. In summary, before starting the WinRIS when running MS-Windows, click on Start, then on
"Run". Type the relevant path and variables on the command line (or select by browsing) lead-
ing to:
WinRIS.EXE COM[x], [speed],8,n,1
(where x is the PC COM port to be used) Of course, the executable command may be used alone without any variable added. Click on OK. It is also possible to create a PC desktop short-
cut icon for WinRIS:
Start by right clicking anywhere on the desktop, Select New, Select Shortcut and type the path as detailed above directly on the command line (with or without variables). Click Next, Type in an applicable name for the shortcut icon, Click Next Select an icon (your choice) and Click on Finish. Command line settings override the environment variable, if any. 120 20170-201 18 ParagonPD Technical Manual Figure 16 - WinRIS main screen 4.3 Window This program uses one main display screen only.

DSR signal is High indicator CTS signal is High indicator TXON (Modulated) TXON (Unmodulated) Ping Address and Ping button While a button is in-use for test transmissions, all others are inoperative. DSR signal is High indicator 4.4.5.1 The Data Set Ready (DSR) indicator light, located on the button bar (leftmost), is an RS-
232 protocol port indication. When lit, it indi-
cates proper connection and that the value is 120 20170-201 22 ParagonPD Technical Manual High. The DMP protocol used requires that DSR be normally asserted. CTS signal is High indicator 4.4.5.2 The Clear-to-Send (CTS) indicator light, lo-
cated on the button bar (second indicator from the left), is an RS-232 protocol port indication. When lit, it indicates proper connection and that the value is High. The DMP protocol used re-
quires that CTS be normally asserted. Channel Selection 4.4.5.3 ParagonPD uses its default radio channel. No channel selection being available, all channels are grayed-out and the Show All Channel Fre-
quencies button is disabled. TXON Tests 4.4.5.4 TXON test functions are selected by choosing Test from the file menu, then Modulated or UnModulated command or by pressing the relevant button on the Toolbar. Unmodulated Carrier 4.4.5.4.1 Unmodulated carrier gives a clear carrier and is frequently used for checking:
Frequency error Forward and reverse power Press the TXON (Unmodulated) button to transmit an unmodulated 20-seconds test signal on the channel selected or until the button is pressed again. The functions of all the other buttons are inop-
erative during test transmissions. Power check:
1- Connect an in-line power meter between the radio and the antenna. Measure the forward (nominal 40W for UHF model and 35W for 800MHz model) and re-
flected power levels by powering TX ON (<5%
of forward power or as specified by System Eng.). Modulated Carrier 4.4.5.4.2 Test transmission generates a carrier modulated with 1kHz sinewave, at deviation level that de-
pends on model and network speed as shown in Table 8. This function is frequently used for checking frequency deviation. Press the TXON (Modulated) button to begin transmitting a 20-seconds modulated test signal on the channel or until the button is pressed again. The functions of all the other buttons are inop-
erative during test transmissions. Table 8 Carrier deviations for Tone or Data Modulation Carrier Modulation Tone Data Network Speed

1. Remove the receiver (T885) module from the ParagonPD rack frame 2. Remove the receiver top cover (nearest the handle). 3. Connect the ParagonPD Extender Rail kit between the RX module and the empty chassis receiver slot. 4. Set the multimeter to read DC Volts. 5. Apply power to the ParagonPD. 6.2.2.2 Synthesizer Alignment Single channel: Connect the multimeter to the long lead of L1 in the VCO (this measures the synthesizer loop voltage). Tune VCO trimmer C6 for a synthesizer loop voltage of 7V (working range is between 3V to 10V). Multiple channels: Select the middle channel via the EPROM PCB DIP switch. Adjust the VCO loop to 7V. All channels should lie within the upper and lower limits of 10V and 3V respectively. 6.2.2.3 Front-End Alignment 1) IFR COM120B settings:
a) Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R output and the receiver antenna connector. b) Select the generator mode (GEN button) and set to the main receiver channel fre-
quency c) Select and turnon GEN2 d) Set the FM Deviation to 3kHz (full channel) or 1.5kHz (half channel) using 1 kHz sine e) Select SINAD meter 2) Monitor the SINAD by connecting an X1 scope probe to the Demod O/P test point (close to PL103 in the first section from the module front panel) or on the relevant backplane board at SK1 pin 6 (see Figure 30 for test point location). 3) Adjust the helical resonators #H1 to #H3 for best SINAD. 4) Continually decrease the RF level to reach 12dB SINAD, then re-do steps 3) and 4) again. (minimum requirement to reach is 12 dB SINAD for 110 dBm) 5) Perform the SINAD linearity tests described in the next paragraphs below. If it fails to pass the requirement, contact your Dataradio technical support. 120 20170-201 34 ParagonPD Technical Manual WARNING: Do not attempt to re-tune the IF stages (i.e. L312 to L318). These adjustments do not need to be re-adjusted after frequency re-
programming. Touching these coils will have a direct impact on the DSP mo-
dem coefficient settings and may significantly reduce the radio performances over data. 6.2.2.4 SINAD and Linearity Check 1. Apply the following settings to the IFR:
- Generator mode, Output T/R
IFR TX frequency to match the main radio RX frequency Filter set to wide band (no audio filter) Select Gen2 (Modulating tone fixed to 1KHz). All other Gen must be off, except for wideband. Set deviation to 3.0KHz for full channel or 1.5KHz for half channel radios.
2. Lower the RF level to get a 12dB SINAD reading. Level must be better than -110dBm
(including cable loss). 3. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) above the main radio RX frequency, record the SINAD reading. It should remain within 1.5dB from the on frequency SINAD reading. 4. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) below the main radio RX frequency, record the SINAD reading. It should remain within 1.5dB from the on-frequency SINAD reading. Note:
If one of the above requirements is not met, try to re-tune the front-end. If it is still failed, contact your Dataradio technical support. 6.2.2.5 RSSI Adjustment 1. Apply an on-channel signal from the RF generator at a level of -110dBm modulated by a 1 kHz tone at a deviation of 3kHz (full channel) or 1.5kHz (half channel). 2. Adjust RV301 (RSSI level) to give 2.0V RSSI output when measured with a multimeter at SK301 pin 2 or on the relevant backplane board at SK1 pin 5 (see Figure 30 for test point lo-

Note 2: When the synthesizer is unlocked, the front panel green LED called "Supply" will be flashing showing that it needs to be re-tuned. 6.2.3.1 Initial Setup 1. Shut down power to the base station 2. Prepare the multimeter to read DC Volts. 3. Remove the exciter (T881) module from the base station rack frame 4. Remove the exciter top cover (nearest the handle). 5. Connect the ParagonPD Extender Rail kit between the exciter module and the empty chassis exciter slot. 6. Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R out-
put and the exciter antenna connector. 7. Apply power to the base station 6.2.3.2 Synthesizer Alignment Single channel: Connect the multimeter to the long lead of L1 in the VCO (this measures the synthesizer loop voltage). Tune VCO trimmer C6 for a synthesizer loop voltage of 7VDC. Multiple channels: Adjust the VCO loop to 7V using the middle frequency channel. All channels should lie within the upper and lower limits of 10V and 3V respectively. Note: Normally, the fast TX key option is installed and the synthesizer is always ener-
gized. Where that option was not fitted, key the transmitter by pressing the front panel Carrier button to make the above adjustment possible. 6.2.3.3 TX Frequency Error Adjustment 1. Apply the following settings to the IFR:

- Connect the coaxial cable from the IFR T/R to the Exciter output connector 2. Key the Exciter by pressing the module PTT button. The output power must be:
800MHz (T881) = 4W 300mW. 3. If 4Watts is not reached, adjust helical #L300 for maximum power output (which should be at least 7W); adjust RV356 down to 4W. 120 20170-201 37 ParagonPD Technical Manual 6.2.4 Power Amplifier Module (T889) 1. Re-install the exciter module into the Paragon rack frame 2. Connect the Exciter module to the Power Amplifier 3. Connect the Power Amplifier output to the IFR T/R connector or to a stand-alone BIRD style power meter, terminated with a 150W dummy load. 6.2.4.1 Power Amplifier Power Out 1. Set RV63 (Power adjustment, access on the front panel) fully clockwise. 2. Key the transmitter from the exciter Carrier button. The power output should exceed 90W. 3. Adjust RV69 (Driver power, access from the left end side) until the output power drops to 90W. 4. Adjust RV63 (Power) to reduce power output to its nominal value (70W) or lower as re-
quired. 5. Cable loss should be included in the reading. 6.2.4.2 Forward Power Alarm Level 1. Power up the T889 and adjust RV63 (Power) so that the output power is at the alarm level required, usually 20% lower than nominal value (e.g. 40W if the PA normally op-
erates at 50W). 2. Adjust RV48 (Forward power Alarm set) so that the forward power alarm LED lights. 3. Adjust RV63 (Power) for the normal operating power level. 6.2.4.3 Reverse Power Alarm Level (Optional) 1. Power up the T889 and adjust RV63 (Power) for the normal operating power level. 2. Place a known mismatch of the required value (e.g. 3:1 VSWR) and adjust RV52 (re-
verse power alarm set) so that the reverse power alarm LED lights. Example: A VSWR of 3:1 can be simulated by connecting an undetermined 3 dB pad to the PA output. This will result in a loss of 6 dB. 120 20170-201 38 ParagonPD Technical Manual FRONT PL103 Demod output RSSI Test point:

gonPD base station radios (half & full channels). 6.3.1 Recommended Items
- T800win programming kit for Series II:
486 PC or better, MS-Windows 3.1 or later
- PGM800Win programming software user's manual
- PGM800Win Windows based programming software
- T800-01-0002 programming cable (DB-25 to RJ-45 cable)
- Standard 25-pin parallel cable (terminated Male/Female) 6.3.2 Module Programming Before starting programming, have a PC running MS-Windows and the Tait PGM800Win software for Series II Base station. This program supports the use of a mouse but may be used without one if required. Keyboard access follows the conventional MS-Windows method as briefly described below:
- Press and hold the Alt key while pressing at the same time the relevant hotkey as indicated by an underlined letter on the menu command.
- On a drop-down menu, press only the hotkey without pressing the Alt key.
- Use the Tab key to cycle available fields and the Enter key to validate entries. E.g. Pressing Alt+F opens the File drop-down menu and pressing A opens the Save As di-
rectory service box. Receiver VCO and front-end alignment will be required when new receiver frequency is pro-
grammed outside the radio tuning range:
UHF = 2.5 MHz from previous center frequency. VHF = 1.5 MHz from previous center frequency. Exciter and PA alignment will be required when new transmitter frequency is programmed out-
side the radio tuning range:
VHF & UHF= 4 MHz from previous center frequency. 1. Connect the PC, via the supplied programming lead, to the speaker panels front-mounted RJ11 connector. 2. Run Tait PGM800Win program and follow instructions found in the T800 Programming Software Users Manual to select the proper module to be programmed. 3. Program required channel's frequencies. Do not program any CTCSS tones on channels. Do not change any other parameters. Refer to Figure 23, Figure 24, Figure 25 and Figure 26 for screen program examples. 4. Save the base station programming info to a file for further reference. 120 20170-201 41 ParagonPD Technical Manual Figure 23 - Receiver System Information Figure 24 - Receiver Channel Information screen 120 20170-201 42 ParagonPD Technical Manual Figure 25 - Exciter System Information screen Figure 26 - Exciter Channel Information screen 120 20170-201 43 ParagonPD Technical Manual 6.3.3 Channel Selection via DIP Switches The backplane-mounted DIP switch settings override the default channel programmed by PGM800Win. To set a default channel via the software, all DIP switches must be set to OFF (i.e. 00000000). When a switch is Off, its binary count is active; when a switch is ON its binary count is in-
active. The various DIP switch combinations of ON or OFF make up a binary total, which identifies the channel number. To select a channel, set the appropriate DIP switch or switches to OFF to make the binary count total the channel number you want. Set all other switches to ON. It is recommended to set both SW1 (RX) and SW2 (TX) to the same settings on both back plane boards. Example: To select channel 5, set the DIP switches as shown below:

Note 2: When the synthesizer is unlocked, the front panel green LED called "Supply" will flash indicating that it needs re-tuning. Warning, The LED will also flash when the unit is in setup mode while connected to the PGM800win program. 6.4.2.1 Initial Setup This initial setup will be used during all receiver alignment procedures described be-
low:
1. Remove the receiver (T855 or T835) module from the ParagonPD rack frame 2. Remove the receiver top cover (nearest the handle). 3. Connect the ParagonPD Extender Rail Kit for Series II to the empty chassis receiver slot. 4. Prepare the multimeter to DC Volts. 5. Apply power to the ParagonPD. 120 20170-201 45 ParagonPD Technical Manual 6.4.2.2 Synthesizer Alignment Single channel: Connect the multimeter to the long lead of L1 in the VCO (this measures the synthesizer loop voltage). 1. T855 (UHF) Tune VCO trimmer C6 for a synthesizer loop voltage of 10V DC. 2. T835 (VHF). Tune VCO trimmer CV1 for a synthesizer loop voltage of 9VDC. Multiple channels:
1. T855 (UHF) Adjust the VCO loop to 10V using the middle channel. 2. T835 (VHF) Adjust the VCO loop to 9V using the middle frequency channel. 3. All channels should lie within the upper and lower limits of respectively All channels should lie within the upper and lower limits of 16V and 3V respectively for the T855 and within 13V and 5V for the T835. 6.4.2.3 Front-End Alignment 1. IFR COM120B settings:
a) Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R output and the receiver antenna connector. b) Select the generator mode (GEN button) and set to the main receiver channel fre-
quency c) Select and turnon GEN2 d) Set the FM Deviation to 3kHz (full channel) or 1.5kHz (half channel) using 1KHz sine e) Select SINAD meter f) Use a X1 scope probe connected to SINAD input and monitor the Discriminator O/P on the backplane at SK1 pin 6 (RX-audio1). Alternately, it is also possible to moni-
tor at the receiver TP314 (T855) or at the receiver IC350 pin 7 (T835). 2. Adjust the helical resonators for best SINAD: #FL410 and #FL420 (T855) or L410, L420, L460 and L470 (T835). 3. Continually decrease the RF level to reach 12dB SINAD, then re-do step 2) & 3) again.
(minimum requirement to reach is 12dB SINAD for -110dBm) 4. Perform the SINAD linearity tests described in paragraph 6.4.2.4. If it fails to pass the requirement, contact your Dataradio technical support. WARNING: Do NOT attempt to re-tune the IF stages
(i.e. L310 to L390 for T855, CV318 or L330 to L360 for T835). These adjustments do not need to be re-adjusted after frequency re-
programming. Touching these coils will have a direct impact on the mo-
dem DSP coefficient settings and may reduce significantly the radio per-
formances over data. 6.4.2.4 SINAD and Linearity Check 1. Apply the following settings to the IFR:
a) Generator mode, Output T/R 120 20170-201 46 ParagonPD Technical Manual b) IFR TX frequency to match the main radio RX frequency c) Filter set to wide band (no audio filter) d) Select Gen2 (Modulating tone fixed to 1KHz). All other Gen must be off. e) Set deviation to 3.0KHz for full channel or 1.5KHz for half channel radios. f) Use a X1 scope probe connected to IFR SINAD input and monitor the Discriminator O/P on the backplane at SK1 pin 6 (RX-audio1). Alternately, it is also possible to monitor at the receiver TP314 (T855) or at the receiver IC350 pin 7 (T835) 2. Lower the RF level to get a 12dB SINAD reading. Level must be better than -110dBm
(including cable loss). 3. Offset the IFR TX frequency 2kHz (full channel) or 1kHz (half channel) above the main radio RX frequency, record the SINAD reading. It should remain within 1dB from the on frequency SINAD reading. For T855, use above values, for T835 use 1.5kHz (full chan-
nel) or 0.8kHz (half channel). 4. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) below the main radio RX frequency, record the SINAD reading. It should remain within 1dB from the on-frequency SINAD reading. For T855, use above values, for T835 use 1.5kHz (full channel) or 0.8kHz (half channel). Note: If one of the above requirements is not met, try to re-tune the front-
end. It still failed, contact your Dataradio technical support. 6.4.2.5 RSSI Adjustment (UHF: T855)
- Apply an on-channel signal from the RF generator at a level of -110dBm modulated by a one kHz tone at a deviation of 3kHz (full channel) or 1.5kHz (half channel).
- Adjust RV320 (RSSI level) to give 2.0V RSSI output at SK330 pin 2 or on backplane SK1 pin 5 when measured with a voltmeter (See Figure 30 for test point location).
- Vary the RF level and check the RSSI output voltage ( Figure 28):
1) At 120 dBm: 1.2 VDC (+0.20 0.45VDC) 2) At 90 dBm: 4.0 VDC (+0.20 0.20 VDC) 3) At 80dBm: 5.0 VDC (+0.20 0.35VDC) If the requirement cannot be reached, contact your Dataradio technical support.

IFR RX frequency to match the main radio TX frequency IF Filter set to 30KHz
- Receiver mode, Output T/R
- Select auto range in the Power reading window
- Connect the coaxial cable from the IFR T/R to the Exciter output connector 2. Key the Exciter by pressing the module PTT button. The output power must be:
- VHF (T837) = 800 mW 200mW
- UHF (T857) = 1W 300mW
800 (T881) = 4W 300mW 6.4.4 Power Amplifier Module (T859 or T839)
- Re-install the exciter module into the ParagonPD rack frame
- Connect the Exciter module to the Power Amplifier.
- Connect the Power Amplifier output to the IFR T/R connector or to a stand-alone BIRD style power meter, terminated with a 150W dummy load.
- Forward and reverse power alarm set (control) are identified on the PA cover. 6.4.4.1 Power Amplifier Power Output
- Key the transmitter on the exciter and adjust the PA output for 100W using front panel power control. If power cannot be reached, refer to section 6.4.4.4 for T859 UHF model or to Tait T839 service manual for T839 model. Cable loss should be included in the reading. 6.4.4.2 Forward Power Alarm Level 1. Power up the PA and adjust front panel power control so that the output power is at the alarm level required, usually 20% lower than nominal value (e.g. 40W if the PA nor-
mally operates at 50W). 2. Adjust the forward power alarm set (T859: RV48 or T839: RV101) so that the forward power alarm LED lights. 3. Adjust front panel power control (T859: RV63 or T839: RV109) for the normal operat-
ing power level 6.4.4.3 Reverse Power Alarm Level (Optional) 1. Power up the PA and adjust the front panel power control for the normal operating power level. 2. Place a known mismatch of the required value (e.g. 3:1 VSWR) and adjust the reverse power alarm set (T859: RV52 or T839: RV105) so that the reverse power alarm LED lights. Example:
A VSWR of 3:1 can be simulated by connecting an unterminated 3dB pad to the PA output. This will result in a return loss of 6dB. 120 20170-201 51 ParagonPD Technical Manual 6.4.4.4 Tait T859 (UHF) Standard Tuning Procedure 1. For sets with serial numbers following 217262, set RV69 (driver power level) fully clockwise. 2. For all units, preset the tuning controls as shown in Figure 31 Figure 31 - T859 Tuning Settings 3. Set RV63 (front panel power control) fully clockwise. 4. Key on the exciter (press PTT button). 5. Adjust CV1 for maximum output. 6. Adjust CV8 for maximum output. 7. Adjust CV32 for maximum output. 8. Adjust CV51 and CV57 for maximum output. 9. Adjust CV34 and CV35 for maximum output. 10. Recheck all settings. The power output should exceed 110W. 11. For sets with serial numbers following 217262, adjust RV69 (driver power level) until the output power drops to 110W. 12. For all units, adjust RV63 to reduce the power output to the required level (normally 100W). 6.4.4.5 Tait T859 Tuning for Best Efficiency 1. Insert a Shunt current device (HP 34330A Shunt 30A ) between the power supply red wire and its 13.8Vdc output, then connect the shunt to the multimeter (VDC scale) 2. While transmitting, monitor the current. It should remain under 22A. 3. Retune CV32, CV51 and CV57 towards maximum capacitance to obtain minimum sup-
ply current, but do not exceed a maximum drop of 0.5A per control. 4. Check that the supply current is <22A for 100W output power. Note:
These control settings are normally very close to minimum supply current. If the current is reduced too far, maximum power output will drop and 2f rejection may degrade. 120 20170-201 52 ParagonPD Technical Manual IC 310 SK330 pin 2 Figure 32 - T855 Receiver Tuning Controls Location 120 20170-201 53 ParagonPD Technical Manual TCXO Figure 33 - T857 Exciter Tuning Controls Locations 120 20170-201 54 ParagonPD Technical Manual L410 L420 L1 L460 L47 L330 CV318 L340 RSSI Test Point P207 IC 700 CV1 L350 IC 350 L360 Figure 34 - T835 Receiver Tuning Controls Location 120 20170-201 55 ParagonPD Technical Manual IC700 TCXO L1 CV1 IC220 Figure 35 - T837 Exciter Tuning Controls Location 120 20170-201 56 ParagonPD Technical Manual Appendix 1 - ParagonPD Deviation adjust 1. Using the WinRIS, press TX ON (Modulated) and record deviation level as read on the IFR. 2. Using Windows Notepad, Edit the .bp2 file named with the corresponding BDLCPD serial number (e.g. abcd.bp2). Save as to another file name and keep it in case something goes wrong while changing a parameter. 3. Locate the line labeled Dev0 Par85= and record the value beside the = sign. This is the corresponding parameter value to the deviation read in step 1. 4. Apply the following formula to determine the new parameter value to be set:
(New Par85 value) = [(initial Par85 value) X (target deviation) / (deviation read)] + 2 5. Change the value in the file, Save as using the BDLCPD serial number file name. 6. Run the WinRIS again and do a Put From. From the opened window, select the file that you just made the change to and then press OK 7. Again, check deviation level while pressing TX ON (Modulated). If the level is now correct, press Stationreset to make the change permanent. Otherwise do step 5 again, changing the value entered in the file by 1 or 2 digit(s) up or down, fine-tuning directly the Par85 (DSP deviation) parameter. Do steps 6 and 7 again to confirm acceptance. This last step may have to be repeated once or twice while varying the entered value up or down. If unable to obtain the correct level after editing up and/or down by no more than 2, contact System Engineering. 120 20170-201 57 ParagonPD Technical Manual 7.
