For increased data security, the modem supports the U.S. Government developed Digital Encryption Standard (DES) data encryption and decryption protocols. This capability requires installation of third-

party IP compliant DES encryption and decryption software. The standard IPSeries base station circuit board contains five (5) main sections defined below:

Input/Output Circuitry associated with one of the following base stations data connectors:

System Controller 369548.DOC

RS232 Serial Port DB9 Data Connector

RJ45 Ethernet 10 Base T Interface Connection Houses the modem, diversity, and Ethernet circuitry. Manages the operation of the base stations modem providing transmit timeout protection in the event a fault causes the base station to become halted in the transmit mode. The system controller also handles the loading of selected transmit and receive frequencies into the injection synthesizer. Includes memory for storage through Electrically Erasable Programmable Read Only Memory (EEPROM) of the base stations operating parameters, which are retained after the base stations power is cycled off. Page 3 Modems Diversity Reception RX Injection Transmitter Receiver 1/Receiver 2/

Receiver 3 Power Supply SECTION 1: THEORY OF OPERATION Convert data into an analog audio waveform for transmission and analog audio from the receiver to serial data interface. There is one

(1) modem that is dedicated to the transmit operation and two (2) modems dedicated to the receive operation. The modem dedicated to the transmit supports a 115.2 KBPS data transmission rate on the serial port, SLIP protocol, and 19.2 KBPS and 32 KPBS over-the-air data transmission rate. Provides Forward Error Correction (FEC) and Error Detection (CRC), bit interleaving for more robust data communications, and third generation collision detection and correction capabilities. Circuitry selects one of three (3) diversity receiver audio outputs for processing by the modem by comparing the Received Signal Strength Indication (RSSI) output from each receiver. Audio from the receiver with the highest RSSI value is passed to the modems. The Injection Synthesizer board provides a highly stable local oscillator signal for the three (3) receivers. This displays a serial data input/output interface, synthesizer, and VCO. Consists of an exciter and a power amplifier module covering various frequency bands in segments. A different power amplifier module is required for each segment. The transmitter power control is included with the power supply circuitry on the same board. Uses three (3) discrete receivers tuned to the same frequency. The three (3) receivers are required to support IPMobileNets base station Diversity Reception System (DRS). NOTE:

Some installations use only two (2) receivers. The receivers are double-conversion superhetrodynes with an Intermediate Frequency (IF) of 45 MHz. Each receiver consist of bandpass filters, RF amplifiers, a mixer, 45 MHz crystal filter, and a one-chip IF system. The injection synthesizer provides the first local oscillator signal and outputs from each receiver including RSSI and analog audio for Diversity Reception. Power supply circuitry derives the various operating voltages required by the base station. Fixed voltage regulators are employed through the base station for this purpose. 369548.DOC Page 4 SECTION 1: THEORY OF OPERATION IP8B Base Station Section Descriptions System Controller This section displays the Central Processing Unit (CPU)(U1), clock, and power-on reset circuitry. It provides more processing power than required for future capabilities to be incorporated without changing processors. Such capabilities include data encryption/decryption (DES) and remote fault monitoring. U1 features a 16-bit address bus and 128K of internal flash random access memory (RAM). NOTE: To enter the programming mode it is necessary to reset the switch (S1) and power up again. CPU operations are controlled by Y3 an 18.432 MHz clock module. Capacitor (C1) and an internal Schmidt trigger circuit inside of U1 generates the power on reset signal. The RESET* output from U1 drives a latch and decoder found elsewhere on the board.

(refer to schematic on page 26) This section displays the RAM, decoder, EEPROM, and programming power supply circuitry. U2 is a 512K x 8 bit static RAM chip, which provides temporary storage of base station configuration data while the power is on. This is necessary in order to program the base station. U2 is controlled directly by the address, data, and control busses from the CPU. Chip U5 decodes the A11-A14 address bus to provide chip selects for the modem and EEPROM memory. Chip U6 is an 8-bit latch. It latches inputs from the D0-D7 bus and lights the front panel status indicators (TX, CD, RX1, RX2, and RX3). Chip U3 is a serial EEPROM, which provides 2K bits of pre-programmed data storage for the CPU. Data is clocked out of U3 by EECLK, and back into the CPU via EEDATA. A programming power supply is required for the flash RAM inside of the CPU, and this function is performed by U4. This chip is a low dropout voltage regulator with a shutdown control. Resistors R22 and R21 set the output voltage. When the base station configuration data is to be stored in flash RAM, the CPU makes VPP_ENABLE high. This turns on the regulator, producing a 12-volt output via VPP for the flash RAM. This section displays a dedicated processor and voltage regulator. Chip U7 is a processor, which permits manual keyboard operation of the base station. Regulator VR2 provides 5 volts DC power for all logic circuitry on the System Controller Board. Input/Output

(refer to schematic on page 30) This section displays the CPU input/output circuitry. Chip U8 is an RS232 transceiver, which interfaces the CPU to the modem via J1. From there, the RS232 data goes directly to a rear panel DB9 connector. U8 converts 5-volt logic-level data to +/-12 volt data in RS232C form, and vice-versa. A charge pump power supply on the chip converts the +5 volt DC power to the +/-12 volt levels required. The charge pump uses capacitors (C28 to C31) to generate voltages. NOTE: The RS232 serial port data transmission rate of the base station is 115.2 KBPS. Modem Switching This section displays the connector wiring and modem switching circuitry. Connector J7 is routed to the front-panel TX, CD, and RX1-RX3 LED indicators. The base station will also accept modulation from an external source (modem or amplified microphone audio). Transmission gate U10A switches this signal source. 369548.DOC Page 5 Modem SECTION 1: THEORY OF OPERATION

(refer to schematic on page 29) This base station uses separate modems for receive and transmit functions so that full-duplex operation may be obtained. The A0-A1 address bus in addition to the individual read (RD*), write (WR*), and chip select (MODEMTXCS*) lines control all three (3) modems. Modem operations are timed by Y2, a 4.9152 MHz clock module. Modem chip U14 is dedicated to the transmit operation. Data from the D0-D7 bus is read by the chip, and then converted to a 4-level FSK analog signal, which appears on the TXOUT pin. Op amp U21B buffers the signal, which becomes the MODEM_TXMOD output. From this point, the signal is routed to the modulation circuitry on the Exciter Board. Chip U14 has the ability to demodulate receiver audio, although this capability is not used in most systems. Incoming data-bearing audio from the Diversity Reception circuitry (and selected receiver) appears at DISC_AUDIO. The signal passes through resistor R54 and into the modem chip. Resistor R52 and capacitor C41 serve as feedback elements, limiting both the gain and bandwidth of an amplifier within U14. The modem chip demodulates the audio into 8-bits of data, which exit U14 on the D0-D7 bus. Chip U14 also provides a bias voltage for the analog circuitry on the Exciter Board. This voltage is about 2.5 volts DC, and it appears on the VBIAS line. The purpose of VBIAS is to bias the Exciter Board analog circuitry for proper operation. Please note that if this voltage is low or missing, the Exciter Board circuitry may not work. Modem chip U15 is dedicated to the receive operation. Incoming data-bearing audio from the Diversity Reception circuitry (and selected receiver) appears at DISC_ AUDIO. The signal passes through resistor R56 and into the modem chip. Resistor R55 and capacitor C46 serve as feedback elements, limiting both the gain and bandwidth of an amplifier within U15. The modem chip breaks down the audio into 8 bits of data, which exit U15 on the D0-D7 bus. Modem chip U16 is also dedicated to the receive operation, although it may not be used in this application. The operation of U16 is exactly the same as U15. Receive Signal Strength Indication Comparator This section displays the RSSI comparator circuitry. A series of comparators (U20BCD) simultaneous compare RSSI1 to RSSI2, RSSI2 to RSSI3, and RSSI1 to RSSI3. Within this process eight (8) possible results are then forwarded by the comparators to a series of NAND gates (U18ABC), which reduce the number of results to three (3) and translates the results for an analog multiplexer (U19A). To determine which of the three (3) results is the strongest, the following needs to occur:

For Receiver 1 to be selected as the strongest signal, both input pins on the NAND gate (U18D) must

(refer to schematic on pages 32 & 33) go high (driving pin 7 of U19A). If Receiver 1 has the strongest signal, a light emitting diode

(LED)(D1) lights indicating Receiver 1 was selected.

For Receiver 2 to be selected as the strongest signal, the inverter (U17B) must go high (driving pin 6 of U19A). If Receiver 2 has the strongest signal, D2 lights indicating Receiver 2 was selected.

For Receiver 3 to be selected the strongest signal, the inverter (U17C) must go high (driving pin 5 of U19A). If Receiver 3 has the strongest signal, D3 lights indicating Receiver 3 was selected. SEL_RSSI is the output selected with the strongest signal. When RSSI voltage exceeds a threshold, another LED (D4) lights. As the other three (3) LEDs, this circuit is intended as a diagnostic tool. It provides a go/no go indication that an RF signal has been received. A pot (R74) sets the turn-on voltage. 369548.DOC Page 6 SECTION 1: THEORY OF OPERATION

(refer to schematic on page 34) Baseband This circuitry amplifies the audio from each receiver, routes it through a RF multiplexer, and selects the audio from the receiver with the highest RSSI value. The comparator circuit on the previous sheet controls it. There are three (3) channels of audio, with separate gain and DC offset adjustments to compensate for performance differences in the receivers. For example, incoming audio from receiver 1 appears at AUDIO 1. An op amp (U12D) is then amplifies the audio. A pot (R72) adjusts the gain, while another pot

(R57) adjusts the DC offset on the output. The amplifier output passes through a RF multiplexer (U19B), then drives a low pass filter (U9) through another op amp (U12A) and through the AUDIO_OUT line, which goes to a switch (S3) and to pin 4 of a connector (J3). The remaining audio circuits work in the same manner. The output from U19B also appears on DISC_AUDIO, which goes to the CPU (U1) and from there the audio is demodulated by the modems. Receiver Board

(refer to schematic on page 44)

Please be aware that the base station uses three (3) identical receiver boards. As a result, the circuitry will be described only once.

(refer to schematic on page 45) Front end. Incoming signals pass through a bandpass filter (FLT1). The desired signals are amplified by U4 and additional selectivity is provided by a SAW filter (FLT2). The signal passes through an IC mixer

(U5) and the output passes through two (2) crystal filters (FLT3 and FLT4). IF Amplifier The incoming 45 MHz signal passes through C15, C17, and R12 which provides impedance matching to the IF amplifier input. U2 is a super heterodyne IF subsystem. Inside the chip, the signal is applied to a mixer. The mixer also accepts a 44.545 MHz local oscillator input. The local oscillator consists of an internal amplifier, plus crystal (Y1) and associated components. The mixer output passes through Y4, a 455 KHz ceramic IF filter. It is amplified, passed through another 455 KHz ceramic filter (Y3), and on to a second IF stage. The IF output drives a quadrature detector. The phase shift elements for the detector are C8 and Y5. The recovered audio appears at pin 9, while RSSI appears at pin 7. Within the RSSI circuitry, chip U2 uses a detector, which converts the AGC voltage generated inside the chip into a DC level corresponding logarithmically to signal strength. RSSI is used by Diversity Reception on the System Controller to select the receiver with the highest quality signal. A filter consisting of a resistor (R8) and a capacitor (C18) provides high frequency de-emphasis for the audio. The audio is buffered by op amp U1A. From there the AUDIO output line goes to a connector, for hookup to Diversity Reception on the System Controller Board. Resistor (R9) and capacitor (C10) provides RF filtering for the DC RSSI voltage. The RSSI is buffered by op amp U1B. From there the RSSI output line goes to a connector, for hookup to Diversity Reception on the System Controller Board.

Several sets of 455 KHz IF filters (Y4 and Y3) are available to suit receiver selectivity requirements. Should replacement of these filters be required, exact replacement parts must be used. 369548.DOC Page 7 SECTION 1: THEORY OF OPERATION

(refer to schematic on page 20 & 21) Receiver Injection This displays a serial data input/output interface, synthesizer, and VCO. The I/O interface circuitry accepts clock, serial data, and enable signals from the System Controller Board via terminal block TB1. A lock detect (LD) status output is returned to the System Controller Board from the synthesizer. U6 is a hex Schmidt Trigger inverter, which squares up incoming signals for reliable operation of the synthesizer chip. This is necessary because of a cable run between the two (2) boards. The main section of this board is synthesizer chip (U5). The device contains the key components of a phase locked loop (PLL), including a 1.1 GHz prescaler, programmable divider, and phase detector. In operation, the desired frequency is loaded into U5 as a clocked serial bit stream via the CLK and DATA/I inputs. The lock detection circuitry consists of inverters U6E/U6F, diode CR1, and resistor R3. When the synthesizer is in lock, the LD pin on U5 is high, making the LD output on terminal block TB1 high. The UHF injection signal is generated by module VCO1. This device is a wide-range voltage controlled oscillator (VCO). A voltage on the C input determines the VCO frequency. The voltage is generated by the phase detector output (PD/O) of U5, which drives a loop filter consisting of R2, C23, C7, R5, C15, and C16. The filter integrates the pulses, which normally appear on PD/O into a smooth DC control signal for the VCO. The output of VCO1 is attenuated by module AT1, resulting in improved VCO stability. Reference module (Y1) provides a high-stability 10 MHz reference frequency. Y1 is a voltage controlled, temperature controlled crystal oscillator (VCTCXO). This device also has a VC input which accepts a control voltage from pot R7. The pot permits a slight shift in the reference frequency which enables the three (3) receivers to be tuned precisely to the assigned receive frequency. A diode (CR2) provides additional voltage regulation, improving the frequency stability of reference Y1. The RF output circuitry consists of RF amplifier (U4), and two-way power splitters (U3, U1, and U2). U4 increases the signal level to correct for losses in the splitters. The splitter U3 provides two (2) RF outputs. One output drives splitter U1, which provides local oscillator injection for receivers 2 and 3. The other output drives splitter (U2), which drives receiver 1 and the PLL_FEEDBACK input on chip U5.

(refer to schematic on page 49) Exciter Board This section displays the input/output interface, transmitter keying, and power supply circuitry. The input/output interface is built around terminal block (TB1) and Schmidt Trigger inverters (U4). Incoming clock, serial data, and chip select signals on block TB1 are squared up by U4. Then they are sent to the appropriate inputs on the low pass Bessel filter (U2). The EXCDATA source comes from the receive synthesizer on the Injection Synthesizer Board. A Schmidt Trigger chip is used here because of a cable ran to the System Controller Board. The synthesizer returns a lock detect output to the Injection Synthesizer Board via U4D and EXCLD. A regulator (VR3) powers the T/R switch circuitry. When the System Controller Board makes TXKEY*

low, turning on transistor Q4 and FET Q1. This applies 5-volt power to the TXENABLE output, turning on the T/R switch on the Power Amplifier Board. At the same time, transistor Q2 conducts, grounding the KEY* input of the Power Amplifier Board. Finally, inverter U4E goes high and turns on RF switch U5, connecting the VCO output to the Power Amplifier Board for transmission. The power supply consists of two (2) voltage regulators. A regulator (VR1) provides 9-volt power for the VCO. Another regulator (VR2) provides low noise 5-volt power for the logic circuitry, synthesizer chip, and analog circuitry. 369548.DOC Page 8 SECTION 1: THEORY OF OPERATION

(refer to schematic on page 52) Analog Modulation This section displays the analog modulation circuitry. Incoming modem audio from the System Controller Board appears at TXMOD, and is buffered by op amp U3A. If an external modulation source (modem or amplified microphone) is connected to the base stations DB9 connector, audio appears at EXTMOD. From there the audio passes through low pass Bessel filter U2. The audio is inverted and amplified by an op amp (U3B). It then passes on to the VCO module via VCOMOD. Pot R11 adjusts the level to suit the VCO. The 10 MHz reference is also modulated in order to counteract the corrective effects of the synthesizer loop circuitry. For example, if only the VCO were modulated, the synthesizer would try to compensate for the frequency error, caused by the modulation. This effectively reduces the amount of modulation available. Modulating the reference and the VCO simultaneously deceives the loop into not compensating for the modulation, because when the reference frequency goes high, the VCO frequency goes high, and vice-versa. An op amp (U1A) amplifies the AUDIO output from another op amp (U3D) and applies it to jumper block JP1. Pot R4 adjusts the gain of U1A. Op amp (U1B) inverts the phase of the audio and applies it to the other side of jumper block JP1. The purpose of the jumper block is to select the proper phase of the audio. If the wrong phase is used, on modulation peaks the reference will swing in the same direction as the VCO, canceling out most of the modulation. The output from the jumper block goes to the 10 MHz reference via REFMOD. The VBIAS input is a 2.5-volt DC source, which biases the op amps to the correct operating point. It is generated by modem chip (U14) on the System Controller Board. Phase Locked Loop This section displays phase locked loop (PLL) circuitry. The 10-MHz reference (Y1), runs synthesizer

(U6), which in turn controls VCO VCO1. The main section of this board is the synthesizer chip (U6). The device contains the key components of a PLL, including a 1.1 GHz prescaler, programmable divider, and phase detector. In operation, the desired frequency is loaded into U6 as a clocked serial bit stream via the CLK and DATA inputs. The lock detection circuitry consists of inverters U4D, diode CR1, and resistor R28. When the synthesizer is in lock, the LD pin on U6 is high, making the EXCLD output on terminal block (TB1) high. The EXCLD output on TB1 routes the lock detect output from the Exciter Board. This configuration tells the CPU on the System Controller Board that it is acceptable to process received data, or to key the transmitter when LD is high. Otherwise, if a fault in either synthesizer prevents a lock, receive and transmit operation will be inhibited. The switch (JP1) is used to select the supply voltage to chip U6. The UHF injection signal is generated by module VCO1. This device is a wide-range voltage controlled oscillator (VCO). A voltage on the VT input determines the VCO frequency. The voltage is generated by the phase detector output (PD/O) of U2, which drives a loop filter consisting of R31, C50, C28, and C25. The filter integrates the pulses, which normally appear on PDOUT into a smooth DC control signal for the VCO. The output of VCO1 is attenuated by module AT1, resulting in improved VCO stability. RF amplifier U8 amplifies the signal and applies it to a two-way power splitter (U7). One output of U7 is connected to a switch (U5). U5 is enabled by signal TX when the transmitter is enabled. The other output of the splitter provides feedback to U6.

(refer to schematic on page 53) 369548.DOC Page 9 SECTION 1: THEORY OF OPERATION Power Amplifier The transmit injection signal from the RF injection section is applied to the high-powered linear amplifier

(U1) one (1) watt amplifier. The signal is then routed to the final power amplifier boosting the output signal to 20 watts.

Connect the base station to the appropriate components. Power up the base station and computer. The power supply ammeter must read 1.2 amps or less with a 13.8 VDC input. Step 2 Step 3 Receiver Injection Step 1 Step 2 Receiver Step 1 Step 2 Step 3 Using the HP high frequency probe verify that the receiver injection frequency is present at each of the three (3) receivers by monitoring the receivers R24 surface mount pad which lies on the 50 ohm track between P1 and C43. Adjust R23 on the receiver injection circuit board to set the injection frequency within 10 Hz of the exact injection frequency. The amplitude of the injection frequency should read approximately +5 dBm 1 dBm. Using the high frequency probe, monitor the 44.545 MHz second injection frequency at U6 pin 3, adjust trimmer capacitor (C22) to the center of the oscillators oscillation range. The amplitude level of pin 3 of U6 should read between +5 and +10 dBm. Inject an on-frequency signal at a level of 80 dBm, modulated with a 1 KHz test tone at 5.0 KHz deviation into the receiver under test. Check the receivers sensitivity, verifying that the SINAD is 12 dB or better at a maximum level of 119 dBm (-120 is typical). 369548.DOC Page 13 Diversity Reception Step 1 SECTION 2: FACTORY TEST PROCEDURE Inject an on-frequency signal at a level equal to Receiver 1 12dB SINAD level, modulated with a 1 KHz test tone at 5.0 KHz deviation into Receiver 1.

(R72) for 350 mVRMS (1 mV). While monitoring the DC voltage at TP6 adjust audio 1 DC adjustment potentiometer

(R57) for 2.500 VDC (1 mV). The audio AC and DC adjustments are interactive, therefore continue adjusting R72 for 350 mVRMS and R57 for 2.500 VDC until further adjustments are no longer required. Inject on-frequency signal at a level of 80 dBm, modulated with a 1 KHz test tone at 5.0 KHz deviation into Receiver 2. While monitoring the AC voltage at TP6 adjust audio 1 AC adjustment potentiometer

(R71) for 350 mVRMS (1 mV). While monitoring the DC voltage at TP6 adjust audio 1 DC adjustment potentiometer

(R58) for 2.500 VDC (1 mV). The audio AC and DC adjustments are interactive, therefore continue adjusting R71 for 350 mVRMS and R58 for 2.500 VDC until further adjustments are no longer required. Inject on-frequency signal at a level of 80 dBm, modulated with a 1 KHz test tone at 5.0 KHz deviation into Receiver 3. While monitoring the AC voltage at TP6 adjust audio 1 AC adjustment potentiometer

(R53) for 350 mVRMS (1 mV). While monitoring the DC voltage at TP6 adjust audio 1 DC adjustment potentiometer

(R59) for 2.500 VDC (1 mV). The audio AC and DC adjustments are interactive, therefore continue adjusting R53 for 350 mVRMS and R59 for 2.500 VDC until further adjustments are no longer required. Step 22 Receive Data Step 1 Step 2 Adjust the carrier detect potentiometer (R74) to illuminate a level of 116 dBm. Using a calibrated mobile radio, generate uplink data messages using the X=1400,19 command in the IPMessage Utility program. Attach an antenna to one of the base stations receiver ports and verify on the base station monitor screen (HyperTerminal) that the received message data quality are consistently 240 and higher for 1400 character messages. Repeat test for each receiver. 369548.DOC Page 15 Exciter Step 1 Step 2 Step 3 Step 4

Step 5 Step 6

Step 4 SECTION 2: FACTORY TEST PROCEDURE Using the X=1400,19 command, generate data messages so the transmit power and frequency can be checked. Note the power level and then on the power amplifier circuit board adjust the potentiometer (R3) fully counterclockwise (this will enable low power transmit operation). Connect the base stations transmit port to the HP communication test set. While transmitting data messages using the X=1400,19 command, adjust the following:

TCXO Y1 for minimum frequency error

R42 for 5 KHz deviation Transmit output power should be approximately 1mWatt. The REFMOD adjustment needs to be made while the base station is transmitting real data messages to and from a mobile radio. This is most easily done using the ping command to ping the IPNC from a mobile radio. This will cause the base station to repeatedly send data messages and will facilitate the REFMOD adjustment. Connect the base station to the IPNC. Using a calibrated mobile radio operating on the base stations channel, adjust R30 for consistent data quality readings of 248 (as observed on the mobile radios attached PC IPMessage window). Access the MSDOS prompt and ping using the following command:

>;ping 192.168.3.3 t l 500 w 2000 This command will ping the IPNC continuously with a 500-character test message. Press [Ctrl]+C to stop the ping. Connect the base stations transmit port to the communication test set. Using the X=1400,19 command, generate data messages. Slowly increase the base station output power by turning the power control potentiometer clockwise until the power noted in Step 2. Do not exceed 20 watts output power, as this will reduce the life of the amplifier module. If the base station uses a power amplifier, output power must be set to achieve power output specified for the specific base station installation. Perform a close visual inspection of the base station paying close attention to manufacturing related problems such as loose screws, solder practices, etc. Power Amplifier Step 1 Step 2 Step 3 369548.DOC Page 16 IP8B Base Station FCC Label Placement SECTION 3: FCC LABEL LABEL IP8B Base Station FCC Label 369548.DOC Page 17 System Controller Receiver - Top REWORK INSTRUCTION ADD JUMPER (30 AWG INSULATED WIRE) from U19 Pin2 to VIA (RVCC) APPENDIX A: CIRCUIT BOARD DIAGRAMS J2 J3 J1 U8 Y1 C76 1 U13 100 R80 R79 C74 R50 R66 T1 R65 76 R51 C75 75 S3 S2 C77 C28 U10 TP5 S1 TP8 TP4 U4 F1 25 26 16 C84 R62 C83 50 51 C56 109 108 C8 U14 C7 R31 73 72 U15 U16 32 U2 U7 Y2 R33 U20 U19 U18 U17 8 5 C 8 8 R 9 5 C 3 8 R 2 8 R 1 8 R D7

A / 04-September-03 CHAPTER 1: INTRODUCTION Product Description

The content of this manual applies to all frequency ranges of the IPSeries Base Stations, unless otherwise specified. This manual will note key differences when appropriate. The IPSeries Base Stations are intelligent devices designed for the stringent requirements of mobile data communication systems. Intended for mounting in rack units, the base station requires very little room at tower sites and may be connected to via Serial Line Internet Protocol (SLIP) ports or Ethernet. The base station circuit boards are built using surface mount technology (SMT) and through-hole components. At the minimum, the unit requires a 13.8 VDC power supply, antenna system, and high-speed data connection to an Internet Protocol Network Controller (IPNC) system to operate. The base station is typically teamed up with a Power Amplifier (PA) and third-party system components such as antennas, preamplifiers, preselectors, filters, and combiners. Figure 1: IPSeries Base Station External Illustration (Front View) Product Functionality The base station utilizes an internal high-performance 4-level Frequency-Shift Keying (FSK) wireless data modem (19200 bps) for 25 kHz channel spacing, a multi-layered approach to signaling reliability, including patented multi-receiver Intelligent Diversity Reception, dynamic scrambling, data interleaving for burst error protection, Forward Error Correction (FEC), and Viterbi soft-decision algorithms. The IPSeries Base Station technology includes IPMobileNets Diversity Reception (DR) capability. Diversity Reception reduces the number of fades and the effects of multi-path reception. With the use of three (3) antennas, mounted as far apart as possible on the base station tower, the Diversity Reception System (DRS) minimizes the effects of fading. One of the antennas is likely to receive a viable signal while the others may not. DRS minimizes fading effects by comparing the signal levels from the three (3) antennas, and selecting the strongest signal.

Diversity is most effective when the vehicle using an IPSeries Mobile Radio is in motion. 2003 IPMobileNet, Inc. 6 IPSeries MR User Manual / Rev. A / 04-September-03 CHAPTER 1: INTRODUCTION External Features The base station technology is enclosed in a sturdy aluminum case. 1 The product warranty becomes void if an uncertified or unauthorized individual removes the base station cover.

EthernetCtrlr.pdf) available on the Product Documentation CD. Houses the modem, diversity, and Ethernet circuitry. Manages the operation of the base stations modem providing transmit timeout protection in the event a fault causes the base station to become halted in the transmit mode. The system controller also handles the loading of selected transmit and receive frequencies into the injection synthesizer. Includes memory for storage through Electrically Erasable Programmable Read Only Memory (EEPROM) of the base stations 2003 IPMobileNet, Inc. 10 IPSeries MR User Manual / Rev.

Receiver 3 Power Supply CHAPTER 1: INTRODUCTION operating parameters, which are retained after the base stations power is cycled off. Convert data into an analog audio waveform for transmission and analog audio from the receiver to serial data interface. There is one (1) modem that is dedicated to the transmit operation and two (2) modems dedicated to the receive operation. The modem dedicated to the transmit supports a 115.2 KBPS data transmission rate on the serial port, SLIP protocol, and a 19.2 KBPS OR 9.6 KBPS over-the-air data transmission rate. Provides Forward Error Correction (FEC) and Error Detection (using Cyclic Redundancy Check or CRC), bit interleaving for more robust data communications, and third generation collision detection and correction capabilities. Circuitry selects one of three (3) diversity receiver audio outputs for processing by the modem by comparing the Received Signal Strength Indication (RSSI) output from each receiver. Audio from the receiver with the highest RSSI value is passed to the modems. The Injection Synthesizer board provides a highly stable local oscillator signal for the three (3) receivers. This displays a serial data input/output interface, synthesizer, and VCO. Consists of an exciter and a power amplifier module covering various frequency bands in segments. The transmitter power control is included with the power supply circuitry on the same board. Uses three (3) discrete receivers tuned to the same frequency. The three (3) receivers are required to support IPMobileNets base station Diversity Reception System (DRS). NOTE: Some installations use only two (2) receivers. The receivers are double-conversion superhetrodynes with an Intermediate Frequency (IF) of 45 MHz. Each receiver consists of bandpass filters, RF amplifiers, a mixer, 45 MHz crystal filter, and a one-

chip IF system. The injection synthesizer provides the first local oscillator signal and outputs from each receiver include RSSI and analog audio for Diversity Reception. Power supply circuitry derives the various operating voltages required by the base station. Fixed voltage regulators are employed through the base station for this purpose. 2003 IPMobileNet, Inc. 11 IPSeries MR User Manual / Rev.

Step 3 Step 4 Step 5 Step 6 Step 7 Step 8 Step 9 Step 10 Step 11 2003 IPMobileNet, Inc. 16 IPSeries MR User Manual / Rev. A / 04-September-03 CHAPTER 4: PRODUCT INSTALLATION Installation Overview This chapter provides the basic setup involved in the installation process of an IPSeries Base Station. For backhaul requirements, refer to Appendix A of this document. 1 Standard considerations such as air flow clearance above the base station for heat dissipation and ensuring adequate space exists behind the base station for the routing of cables are of primary importance. A minimum clearance of 1 rack space is recommended for natural convection cooling. Adjustment points are available through holes in the base station bottom cover. Sufficient space below the base station should exist to facilitate adjustments. Coax, power, and interface cabling service lengths with neat routing will make the removal and replacement of the base station easier for functional testing and maintenance purposes. To prevent injury and damage to the base station, exercise extreme caution throughout the installation process and follow the reminders listed below.

Follow safety precautions for handling rack unit installations.

Do not alter the components listed in the Installation Requirements section, unless substituions are noted within this chapter. 2003 IPMobileNet, Inc. 17 IPSeries MR User Manual / Rev. A / 04-September-03 CHAPTER 4: PRODUCT INSTALLATION Adjusting the Power The power output of the base station will depend upon whether it will be used to drive an external power amplifier or transmit directly over-the-air.

In either case it is important to measure and set the transmitter power output using a wattmeter and dummy load before connecting it to the power amplifier or antenna system. The base station power is adjusted mechanically by tuning a potentiometer (pot) on the bottom of the base station. Depending upon the model, this pot can be reached through an access hole in the bottom cover on either the exciter board or power amplifier board. Figures 8, 9, and 10 display the Power Adjustment Potentiometer location for the IP1B, IP4B, and the IP8B. 1 Do not use a metal tool to make this adjustment, only use non-conducting alignment tools. Equipment will be damaged if this warning is ignored. Figure 8: Power Adjustment Potentiometer Location for the IP1B Figure 9: Power Adjustment Potentiometer Location for the IP4B 2003 IPMobileNet, Inc. 18 IPSeries MR User Manual / Rev. A / 04-September-03 Step 1 Step 2 Step 3 Step 4 Step 5 1 Step 6 CHAPTER 4: PRODUCT INSTALLATION Figure 10: Power Adjustment Potentiometer Location for the IP8B Connect a computer with the HyperTerminal utility to the base stations monitor serial port.

Refer to the section titled HyperTerminal Setup located in Chapter 5: Programming Instructions for HyperTerminal Setup and access instructions. Launch the HyperTerminal utility. Locate the adjustment hole (see Figures 8, 9, or 10 according to the model being used). Fit the tool to the potentiometer. Key the transmitter on the base station by typing X=1450,10 in the HyperTerminal window. The base station will generate 10 data packets, each 1450 bytes in length.

If this does not work, check the base stations MTU parameter. The X=number must be smaller than the MTU value. To avoid damage to the amplifier, when setting the power to drive an external amplifier, set the base station power below the external amplifiers maximum drive limit. If setting the power to drive an external amplifier, use a wattmeter and dummy load to measure the output power of the base and set it to the amount of drive power that is will be needed for the amplifier.

Be aware that the coaxial cable that will connect the base station to the power amplifier may have completely different characteristics to the test cable used to measure power output. If possible, adjust the power with the coaxial cable that will be used in the system ensuring the power measured is exactly what will be fed into the amplifier. 2003 IPMobileNet, Inc. 19 IPSeries MR User Manual / Rev. A / 04-September-03 Step 7 Step 8 1 Step 9 Step 10 1 CHAPTER 4: PRODUCT INSTALLATION Once the adjustment is made, connect the base station to the external amplifier and connect the wattmeter and dummy load to the amplifiers output. Measure the power output of the amplifier.

If the amplifier does not produce the expected power, additional adjustments to the base station output are necessary. When making large adjustments in power, the external amplifier should be disconnected from the base station and the base stations power reset. Do not attempt to make large adjustments to the output power while the base is connected to the external amplifier or if the external amplifier is not producing any power. The base station power adjustment is very sensitive and it is possible to overdrive an external amplifier and ruin it with just small movements of the power adjustment potentiometer. You must be sure to keep the base stations output power below the input drive limit of the external amplifier. Once the base station power is adjusted, reconnect the base station and the wattmeter to the external amplifier and measure the output power of the external amplifier again using the X=1450,10 command. Once the power amplifier is nearly at the proper output, small adjustments can be made to the power output, while the base station is connected. Turning the power adjustment very carefully while transmitting into the external power amplifier will enable the power to be adjusted to exactly the right level. Be careful not to apply sideways pressure to the adjustment potentiometer, otherwise the circuit can be damaged. Always use a light touch when adjusting base station output power. 2003 IPMobileNet, Inc. 20 IPSeries MR User Manual / Rev.

2003 IPMobileNet, Inc. 23 IPSeries MR User Manual / Rev. A / 04-September-03 CHAPTER 4: PRODUCT INSTALLATION Typical Antenna Configuration Base station antenna configurations may vary from site to site depending on the type of mounting structure, the presence of existing antennas, mounting structure loading limitations, etc. The following information is provided as a guideline for a typical scenario. An otpimal antenna mounting configuration is shown in the figure above. The transmit antenna and receive antennas are located at different elevations. This vertical separation provides the greatest degree of isolation between transmit and receive antennas. The three (3) receive antennas are mounted at the same elevation and are oriented in a 120 degree triangular pattern. A triangular orientation of the receive antennas provides optimal diversity performance in an omnidirectional pattern.

The greater the separation between receive antennas, the greater the diversity gain; therefore, the distance between antennas should be made as great as is practical. Figure 14: Typical Antenna Configuration In the event only two (2) receive antennas are used (i.e. a dual receiver diversity reception system), the receive antennas should be mounted in a broadside orientation with respect to the radio coverage area.

To prevent the antennas radiation pattern from becoming distorted, the immediate area surrounding each antenna should be kept free from conductive objects (i.e. other antennas, guy wires, or the tower structure itself). The amount of clear area required to prevent pattern distorion is equal to the antennas near-field exclusion. 2003 IPMobileNet, Inc. 24 IPSeries MR User Manual / Rev. A / 04-September-03 CHAPTER 4: PRODUCT INSTALLATION Near-Field Exclusion Zone The near-field exclusion zone (NFEZ) is the required distance between antennas to any other surfaces to improve transmit and receive performance. The large radio frequency field that builts up around the antenna upon transmitting is essential for proper data transmission. It can be severely corrupted by metal objects in the NFEZ. As seen in the previous figure, the transmitting antenna is placed at the very top of the tower especially if the base station will be required to transmit in all directions (omni-directional). If the transmitting antenna cannot be positioned on the top of the tower and must be placed on a tower arm, then it is important to realize that coverage will be shaded in the area behind the tower from the anetnna. The installer must be certain that the area of desired coverage is away from the tower and not behind it.

Receiving and transmitting antennas should not be on the same plane, especially VHF and UHF systems where the frequency splits are relatiely small. An antenna in the near-field exclusion zone that is tuned for the same frequency as the transmitting antenna will reradiate the signal and create unwanted effects on the transmittal signal. The receivers will be inundated by high levels of radio frequency energy from the transmitting antenna. This is why it is important to include vertical separation in the plan for the base station installation. The isolation provided by 30 feet of vertical spearation can dramatically improve the performance of the base station. An antennas NFEZ can be calculated as follows:

D

2d2 Where:

D is the distance to the anennas near field boundary d is the antennas longest linear dimension (in the same units as D) is the wavelength (in the same units as D) Maximizing the distance between the receive antennas will provide maximum diversity gain and will minimize antenna radiation pattern distortion. 2003 IPMobileNet, Inc. 25 IPSeries MR User Manual / Rev. A / 04-September-03 CHAPTER 4: PRODUCT INSTALLATION Power Connection To connect the base station power connector, perform the following steps:

Step 1 Figure 15: Base Station Power Connection Connect the power cable to the base station power supply connection (as shown in the figure above). Connect the wires to the appropriate output (+ and -) output posts on the power supply (as shown in the figure above). Step 2 2003 IPMobileNet, Inc. 26 IPSeries MR User Manual / Rev.

CHAPTER 4: PRODUCT INSTALLATION TABLE 7: POST INSTALLATION CHECKLIST CHECKLIST ITEM Scope out the entire area setup to locate any obvious problem areas. Check antenna routing for safety concerns and near-field boundary setup. Use tie wraps, where possible to ensure that all cables routed in parallel are bundled together. Perform appropriate testing to ensure base station works properly.

Description of the problem 2003 IPMobileNet, Inc. 31 IPSeries MR User Manual / Rev. A / 04-September-03 APPENDIX A: BACKHAUL REQUIREMENTS Backhaul Systems Considering the backhaul system between the base station location and the Internet Protocol Network Controller location is one of the most critical elements of data transmission. Once data has been received at the base station, it must be relayed to the IPNC at the user's location quickly, accurately, and reliably. Industry standard backhauls are appropriate for IPMobileNet data transmission as long as data is transmitted cleanly and dependably. Depending upon conditions and accessibility, the preferred method of data transmission to the remote site is through wire. Wired Backhaul The Ethernet backhaul is preferred as it uses a T1 (or fractional T1) line or equivalent, which handles larger volumes of digital data. If the backhaul will be via SLIP connection, then four wire DDS telephone line capable of 56Kbps is recommended.

Do not order a 64Kbps line as it is incompatible with IPMobileNets equipment data transmission speed. One disadvantage of using wired lines is that the system is under the control of an outside agency and telephone line faults or system outages impose potential loss of radio communication through the site affected. Microwave Transmission Link Using a microwave transmission link is another option, which is often used when wire cannot be brought into remote locations. Data transmission is generally very reliable, but adverse conditions can degrade the quality of the data. High winds, ice on the microwave dish, and other environmental variables can cause problems and prevent data or voice from completing transmitting. Newest Backhaul The 802.11 range of products for wireless data transmission. Several models of 802.11 have been used successfully.

Be aware of the possibility of interference on the 2.4 GHz frequency range. The 802.11 product should only be used for short hops with clear line-of-sight in an environment where minimal radio interference will exist. 2003 IPMobileNet, Inc. 32 IPSeries MR User Manual / Rev. A / 04-September-03 APPENDIX A: BACKHAUL REQUIREMENTS Serial Backhaul Capacity The backhaul with the fastest speed that can provide clean, reliable, and dependable transmission should be considered when dealing with backhaul capacity. IPMobileNets base stations operate at four (4) data transmission rates, which include the following:

115,200 bps

57,600 bps

38,400 bps

19,200 bps The optimal goal is to select a backhaul data rate that remains ahead of the base stations data transmittal. For example:

Base Station Backhaul Results 19,200 bps 19,200 bps 19,200 bps 57,600 bps Backhaul does not have the opportunity to remain ahead of the base stations transmittals if data packets are dropped or need to be rebroadcast from the IPNC to the base station. System will be more efficient and always operate at the base stations peak performance never waiting for data to arrive from the IPNC. The 56 Kbps DDS line is typically used to create the 57,600 bps asynchronous data line for the serial line Internet protocol (SLIP) connection between the Internet Protocol Network Controller location and the base station site. 2003 IPMobileNet, Inc. 33 IPSeries MR User Manual / Rev.

A / 04-September-03 GFSK GPS Image Frequency Injection Half Duplex LO Modular Design Multipath NFEZ Noise Figure PCB Phase Linearity Phase Noise GLOSSARY Gaussian Filtered Frequency Shift Keying A form of digital modulation in which the baseband modulation signal is filtered by a low-pass filter with a Guassian response prior to modulating the carrier signal. Global Positioning System An unwanted frequency, which will produce an on-frequency IF (Intermediate Frequency) signal. An injection signal is a signal used in frequency conversion circuits, it is normally mixed with another signal to produce a third signal (which is a sum or difference or the original signal and the injection signal). A dual frequency mode of operation, which inhibits simultaneous transmission and reception. Local Oscillator An on-board oscillator used in frequency conversion circuits. A design in which the major functional components are separated into distinct modules. A radio propagation situation in which multiple RF (radio frequency) signal paths exists between a transmitter and receiver. These multiple paths or multi-path situations can create significant distortion in the received signal. Near-Field Exclusion Zone The Figure of Merit of an amplifier. Specifically, noise figure is a measure of the degradation in SNR (signal-to-

noise ratio) between the input and output ports of a network. Printed Circuit Board Implies a linear relationship between the phase of a signal and the frequency of that signal. A linear phase response ensures constant input to output delays regardless of frequency, import for wireless communication systems. A measure of the purity of a discrete frequency (expressed in dBc/Hz at some offset frequency). 2003 IPMobileNet, Inc. 40 IPSeries MR User Manual / Rev. A / 04-September-03 PLL ppm RF RFI SINAD Sensitivity SMT SNR TCVCXO TIA Transmit Attack Time VCO GLOSSARY Phase Locked Loop - A circuit configuration used to lock the frequency of a VCO (voltage controlled oscillator) to a high stability reference oscillator. Parts Per Million Radio Frequency Radio Frequency Interference The ratio of Signal + Noise + Distortion to Noise + Distortion. The measure of a receivers ability to capture and faithfully reproduce weak signals. Surface Mount Technology electronic components, which make electrical contact on the surface layer of a PCB (as opposed to thru-hole components). SMT devices provide reduced size and increase performance. Signal-to-Noise Ratio Temperature Compensated Voltage Controlled Crystal Oscillator Telecommunications Industry Association The elapsed time from transmit key assertion to 90% rated RF power is achieved. Voltage Controlled Oscillator An oscillator whose frequency can be adjusted by a DC control voltage. 2003 IPMobileNet, Inc. 41 IPSeries MR User Manual / Rev.
