F 1.0 GENERAL 1.1 Introduction This guide presents installation and operating instructions for MDS 1710A/C and MDS 2710 A/C/D series digital radio transceivers. These transceivers (Figure 1) are data telemetry radios designed to operate in a point-to-multipoint environment, such as electric utility Supervisory Control and Data Acquisition (SCADA) and distribution automation, gas field automation, water and wastewater SCADA, and on-line transaction processing applications. They use microprocessor control and Digital Signal Processing (DSP) technology to provide highly reliable communications even under adverse conditions. MDS 1710/2710 Series radios use continuous-phase frequency shift keying (CPFSK) modulation with root duo-binary filtering (the sum of two Nyquist-shaped, root-raised cosine responses). Demodulation uses a Virterbi decoder and equalization with soft decision decoding. Modulation and demodulation is accomplished using Digital Signal Pro-
cessing (DSP). DSP adapts to differences between components from unit to unit, and ensures consistent and repeatable performance in ambient temperatures from 30 to +60 degrees Celsius. The use of Dig-
ital Signal Processing eliminates the fluctuations and variations in modem operation that can degrade the operation of analog circuits. SERIAL NUMBER LABEL LED INDICATORS (4) EXTERNAL INTERFACE CONNECTOR

NOTE:
The narrow bandwidth of the MDS 2710D transceiver is not compatible with standard analog modems, including the widely used Bell 202T. The MDS 2710D is intended for digital RS-232 data only. 1.3 Applications Point-to-Multipoint, Multiple Address Systems (MAS) This is the most common application of the transceiver. It consists of a central master station and several associated remote units as shown in Figure 2. An MAS network provides communications between a central host computer and remote terminal units (RTUs) or other data collection devices. The operation of the radio system is transparent to the computer equipment. 2 MDS 1710A/C and MDS 2710A/C/D MDS 05-3447A01, Rev. F Often, a radio system consists of many widely separated remote radios. A point-to-multipoint or SCADA (Supervisory Control and Data Acqui-
sition) system may be a new installation for automatic, remote moni-
toring of gas wells, water tank levels, electric power distribution system control and measurement, etc. The radio system may replace a network of remote monitors currently linked to a central location via leased telephone line. At the central office of such a system, there is usually a large mainframe computer and some means of switching between individual lines coming from each remote monitor. In this type of system, there is a modulator/demodulator
(modem) at the main computer, and at each remote site, usually built into the remote monitor itself. Since the cost of leasing a dedicated-pair phone line is quite high, radio is often used as an alternative communi-
cation medium. RTU REMOTE RADIO RTU REMOTE RADIO Invisible place holder RTU REMOTE RADIO RTU REMOTE RADIO RTU REMOTE RADIO HOSTSYSTEM MASTER RADIO Figure 2. Typical MAS Point-to-Multipoint Network Point-to-Point System Where permitted, the transceiver may also be used in a point-to-point arrangement. A point-to-point system consists of just two radiosone serving as a master and the other as a remoteas shown in Figure 3. It provides a simplex or half-duplex communications link for the transfer of data between two locations. HOST COMPUTER MASTER RTU REMOTE Figure 3. Typical Point-to-Point Link MDS 05-3447A01, Rev. F MDS 1710A/C and MDS 2710A/C/D 3 Continuously Keyed vs. Switched Carrier Operation The keying behavior of the master station can be used to describe an MAS system. operation means the master station transmitter is Continuously Keyed always transmitting a carrier, even when there is no data to send. The master station is always simultaneously transmitting and continuously listening. Different frequencies must be used for transmit and receive. NOTE:
MDS 1710/2710 radios do not support full-duplex operation. Therefore, switched carrier mode must be set to ON (
). SWC ON Switched Carrier the master station transmitter is keyed to send data and unkeyed to receive. operation is a half-duplex mode of operation where Single Frequency (Simplex) Operation Single frequency operation (also known as simplex) is a special case of switched carrier operation. Single frequency operation is automatically selected whenever the transmit and receive frequencies are set to the same value. Note that data turn-around times are increased when a single frequency configuration is used. 1.4 Product Configurator Codes The full radio model number is printed on the radio enclosure. It pro-
vides key information about how the radio was configured when it was originally shipped from the factory. See Figure 4 for an explanation of the configurator codes.

The following glossary explains many of these terms and will prove helpful in understanding the operation of the trans-
ceiver. Active Messaging This is a mode of diagnostic gathering that may interrupt SCADA system polling communications (contrast with pas-
). Active (or intrusive) messaging is much faster than sive messaging passive messaging because it is not dependent upon the RTU polling cycle. MDS 05-3447A01, Rev. F MDS 1710A/C and MDS 2710A/C/D 5 A figure, normally expressed in dB, repre-
Antenna System Gain senting the power increase resulting from the use of a gain-type antenna. System losses (from the feedline and coaxial connectors, for example) are subtracted from this figure to calculate the total antenna system gain. Bit The smallest unit of digital data, often represented by a one or a zero. Eight bits (plus start, stop, and parity bits) usually comprise a byte. Bits-per-second See BPS. BPSBits-per-second. A measure of the information transfer rate of digital data across a communication channel. ByteA string of digital data usually made up of eight data bits and start, stop and parity bits. Decibel (dB)A measure computed from the ratio between two signal levels. Frequently used to express the gain (or loss) of a system. Data Circuit-terminating EquipmentSee DCE. Data Communications EquipmentSee DCE. Data Terminal EquipmentSee DTE. dBiDecibels referenced to an ideal isotropic radiator in free space. Frequently used to express antenna gain. dBmDecibels referenced to one milliwatt. An absolute unit used to measure signal power, as in transmitter power output, or received signal strength. DCEData Circuit-terminating Equipment (or Data Communications Equipment). In data communications terminology, this is the modem side of a computer-to-modem connection. The transceiver described in this guide is a DCE device. Digital Signal ProcessingSee DSP. DSPDigital Signal Processing. In the transceiver, the DSP circuitry is responsible for the most critical real-time tasks; primarily modulation, demodulation, and servicing of the data port. DTEData Terminal Equipment. A device that provides data in the form of digital signals at its output. Connects to the DCE device. EqualizationThe process of reducing the effects of amplitude, fre-
quency or phase distortion with compensating networks. 6 MDS 1710A/C and MDS 2710A/C/D MDS 05-3447A01, Rev. F Fade MarginThe greatest tolerable reduction in average received signal strength that will be anticipated under most conditions. Provides an allowance for reduced signal strength due to multipath, slight antenna movement or changing atmospheric losses. A fade margin of 20 to 30 dB is usually sufficient in most systems. FrameA segment of data that adheres to a specific data protocol and contains definite start and end points. It provides a method of synchro-
nizing transmissions. Hardware Flow ControlA transceiver feature used to prevent data buffer overruns when handling high-speed data from the RTU or PLC. When the buffer approaches overflow, the radio drops the clear-to-send
(CTS) line, which instructs the RTU or PLC to delay further transmis-
sion until CTS again returns to the high state. Host ComputerThe computer installed at the master station site, which controls the collection of data from one or more remote sites. Intrusive DiagnosticsA mode of remote diagnostics that queries and commands radios in a network with an impact on the delivery of the system payload data. See Active messaging. LatencyThe delay (usually expressed in milliseconds) between when data is applied to TXD (Pin 2) at one radio, until it appears at RXD
(Pin 3) at the other radio. MASMultiple Address System. A radio system where a central master station communicates with several remote stations for the pur-
pose of gathering telemetry data. Master (Station)Radio which is connected to the host computer. It is the point at which polling enters the network. MCUMicrocontroller Unit. This is the processor responsible for con-
trolling system start-up, synthesizer loading, and key-up control. Microcontroller UnitSee MCU. Multiple Address SystemSee MAS. Network-Wide DiagnosticsAn advanced method of controlling and interrogating MDS radios in a radio network. Non-intrusive diagnosticsSee Passive messaging. Passive messagingThis is a mode of diagnostic gathering that does not interrupt SCADA system polling communications. Diagnostic data is collected non-intrusively over a period of time; polling messages are carried with SCADA system data (contrast with active messaging). MDS 05-3447A01, Rev. F MDS 1710A/C and MDS 2710A/C/D 7 Payload dataThis is the applications user communication data which is sent over the radio network. It is the transfer of payload data that is the primary purpose of the radio communications network. Point-Multipoint SystemA radio communications network or system designed with a central control station that exchanges data with a number of remote locations equipped with terminal equipment. PollA request for data issued from the host computer (or master PLC) to a remote radio. PLCProgrammable Logic Controller. A dedicated microprocessor configured for a specific application with discrete inputs and outputs. It can serve as a host or as an RTU. Programmable Logic ControllerSee PLC. Remote (Station)A radio in a network that communicates with an associated master station. Remote Terminal UnitSee RTU. Redundant OperationA station arrangement where two transceivers and two power supplies are available for operation, with automatic switchover in case of a failure. RTURemote Terminal Unit. A data collection device installed at a remote radio site. An internal RTU simulator is provided with the trans-
ceiver to isolate faults to either the external RTU or the radio. SCADASupervisory Control And Data Acquisition. An overall term for the functions commonly provided through an MAS radio system. Standing Wave RatioSee SWR. Supervisory Control And Data AcquisitionSee SCADA. SWRStanding Wave Ratio. A parameter related to the ratio between forward transmitter power and the reflected power from the antenna system. As a general rule, reflected power should not exceed 10% of the forward power ( 2:1 SWR). 3.0 INSTALLATION There are three main requirements for installing the transceiverade-
quate and stable primary power, a good antenna system, and the correct data connections between the transceiver and the data device. Figure 5 shows a typical remote station arrangement. 8 MDS 1710A/C and MDS 2710A/C/D MDS 05-3447A01, Rev.

Typical Remote Station Arrangement 3.1 Installation Steps Below are the basic steps for installing the transceiver. In most cases, these steps alone are sufficient to complete the installation. More detailed explanations appear at the end of these steps. 1. Mount the transceiver to a stable surface using the brackets supplied with the radio. 2. Install the antenna and antenna feedline for the station. Preset direc-
tional antennas in the desired direction. 3. Connect the data equipment to the transceivers DATA INTERFACE connector. Use only the required pins for the applicationDo not use a fully pinned (25 conductor) cable. Basic applications may require only the use of Pin 2 (transmit dataTXD), Pin 3 (Received DataRXD) and Pin 7 (signal ground). The radio can be keyed with the use of the DATAKEY command. Additional connections may be required for some installations. Refer to the complete list of pin functions provided in Table 4 on page 14. 4. Measure and install the primary power for the radio. The red wire on the power cable is the positive lead; the black is negative. MDS 05-3447A01, Rev. F MDS 1710A/C and MDS 2710A/C/D 9 NOTE: Use the radio in negative ground systems only. 5. Set the radio conguration. The transceiver is designed for quick installation with a minimum of software conguration required in most cases. The selections that must be made or veried for new installations are:
Transmit frequency Receive frequency The operating frequencies are not set at the factory unless they were specied at the time of order. Determine the transmit and receive frequencies to be used, and follow the steps below to program them. 6. Connect a hand-held terminal (HHT) to the DIAG. connector. When the HHT beeps, press ENTER to receive the ready > prompt. Set the operating frequencies using the TX xxx.xxxxx (transmit) and RX xxx.xxxxx (receive) commands. Press ENTER after each command. After programming, the HHT reads PROGRAMMED OK to indicate successful entry. Set other transceiver parameters as required. A complete list of transceiver commands is provided in Section 5.0, TRANSCEIVER PROGRAMMING. 10 MDS 1710A/C and MDS 2710A/C/D MDS 05-3447A01, Rev.

tional Yagi (Figure 7) or corner reflector antenna is generally recom-
mended at remote sites to minimize interference to and from other users. Antennas of this type are available from several manufacturers. MDS 05-3447A01, Rev. F MDS 1710A/C and MDS 2710A/C/D 11 Invisible place holder Figure 7. Typical Yagi Antenna (mounted to mast) Feedlines The selection of antenna feedline is very important. Poor quality cables should be avoided as they will result in power losses that may reduce the range and reliability of the radio system. Table 3 shows the losses that will occur when using various lengths and types of cable at 200 MHz. Losses at 130-174 MHz will be slightly lower. Regardless of the type of cable used, it should be kept as short as possible to minimize signal loss Table 3.

The power supply should be capable of providing at least 2.5 amperes of continuous current. The red wire on the power cable is the positive lead; the black is nega-
tive. NOTE: The radio is designed for use only in negative ground systems. 12 MDS 1710A/C and MDS 2710A/C/D MDS 05-3447A01, Rev. F CAUTION USE ONLY REQUIRED PINS 3.5 Data Interface Connections The transceivers DATA INTERFACE connector is used to connect the transceiver to an external DTE data terminal that supports the EIA-232
(formally RS-232) format. The transceiver supports asynchronous data rates of up to 38400 bps. The data rate at the DATA INTERFACE connector may differ from the data rate used over the air. Table 4 lists each pin on the DATA INTERFACE connector and describes its function. Do not use a 25 wire (fully pinned) cable for connection to the DATA INTERFACE connector. Use only the required pins for the application. Damage may result if improper connections are made. Typical applica-
tions require the use of only Pins 1 through 8 for EIA-232 signaling. 3.6 Using the Radios Sleep Mode In some installations, such as at solar-powered sites, it may be necessary to keep the transceivers power consumption to an absolute minimum. This can be accomplished using the Sleep Mode. In this mode, power consumption is reduced to less than 16 milliamperes (nominal). Sleep mode can be enabled under RTU control by asserting a ground (or EIA-232 low) on Pin 12 of the radios DATA INTERFACE connector. When Pin 12 is opened (or an EIA-232 high is asserted), the radio will be ready to receive data within 75 milliseconds. All normal functions are suspended while the radio is in sleep mode. The PWR LED will be off, except for a quick flash every 5 seconds. Sleep Mode Example The following example describes Sleep Mode implementation in a typ-
ical system. Using this information, you should be able to configure a system that will meet your own particular needs. Example:
Suppose you need communications to each remote site only once per hour. Program the RTU to raise an EIA-232 line once each hour (DTR for example) and wait for a poll and response before lowering it again. Connect this line to Pin 12 of the radios DATA INTERFACE connector. This will allow each RTU to be polled once per hour with a significant savings in power con-
sumption. MDS 05-3447A01, Rev. F MDS 1710A/C and MDS 2710A/C/D 13 Table 4. DATA INTERFACE Connector Pinouts Pin Number Input/

Invisible place holder 4.0 OPERATION In-service operation of the transceiver is completely automatic. Once the unit has been properly installed and configured, operator actions are limited to observing the front panel LED status indicators for proper operation. If all parameters are correctly set, operation of the radio can be started by following these steps:
1. Apply DC power to the transceiver. 2. Observe the LED status panel for the proper indications (Table 5). 3. If not done earlier, rene the antenna heading of the station to maxi-
mize the received signal strength (RSSI) from the master station. Use the RSSI command from an HHT connected to the radios DIAG. connector.See Section 5.0, TRANSCEIVER PROGRAMMING. This can also be done with a DC voltmeter as described in Section 4.2, RSSI Measurement. MDS 05-3447A01, Rev.

For more information about the terminal, refer also to the instructions included with each HHT kit. The steps below assume that the HHT has been configured for use with the transceiver (80 character screen display). If the HHT was previously used with a different model transceiver, or if its default settings have been changed, refer to Section 5.2, Hand-Held Terminal Setup for setup details. Follow these steps to connect the HHT:
1. Connect the HHTs coiled cord to the DIAG. (RJ-11) jack on the radio as shown in Figure 9. This automatically places the radio into the control and programming mode. As an alternative, the DATA INTERFACE (DB-25) connector may be used for programming instead of the DIAG. jack. With this arrange-
ment, Pin 23 of the HHT cable must be grounded to enable the diag-
nostic channel. (See Table 4.) 2. When the HHT is connected, it runs through a brief self-check, ending with a beep. After the beep, press

However, proper use of the additional commands allows you to tailor the transceiver for a spe-
cific use, or conduct basic diagnostics on the radio. This section gives more detailed information for the user commands previously listed in Table 7. In many cases, the commands shown here can be used in two ways. First, you can type only the command name to view the currently pro-
grammed data. Secondly, you can set or change the existing data by typing the command, followed by a space, and then the desired entry. In the list below, allowable programming variables, if any, are shown in brackets following the command name. AMASK [0000 0000FFFF FFFF]
The AMASK (alarm mask) command displays or sets which events cause the alarm output signal to be active. Normally, the mask is FFFF FFFF, meaning that any of the 32 possible events will activate the alarm output signal. No special configuration is required for typical applications. Entering the AMASK command alone displays the current setting of alarm events in hexadecimal format. Entering the AMASK command followed by an eight-digit hexadecimal number reprograms the specified events to trigger an alarm. The eight-digit hexadecimal number used as the command parameter is used to classify up to 32 events as alarm triggers for the alarm output status line. (See Table 8 on page 32 for a list of event codes.) The hex value for the mask corresponds to the hex value for the STAT command
(see the STAT command description). 22 MDS 1710A/C and MDS 2710A/C/D MDS 05-3447A01, Rev. F Each bit that is a 1 identifies an associated alarm condition that can trigger the alarm output status line. Each bit that is a 0 treats the asso-
ciated alarm as irrelevant when deciding whether or not to assert the alarm output status line. For more information on tailoring the alarm response, contact the MDS Technical Services Department. ASENSE [HI/LO]
The ASENSE command sets or displays the sense of the alarm output at Pin 25 of the DATA INTERFACE connector. Entering the ASENSE command alone shows whether the alarm output is active high or low. Entering the ASENSE command followed by HI or LO resets the alarm output to active high or low. BAUD [xxxxx abc]
This command sets (or displays) the communication attributes for the DATA INTERFACE port. It has no effect on the RJ-11 DIAG. port. The first parameter (xxxxx) is baud rate. Baud rate is specified in bits-per-second (bps) and must be one of the following speeds: 110, 300, 1200, 2400, 4800, 9600, 19200, or 38400. The second parameter of the BAUD command (abc) is a three-character block indicating how the data is encoded:
a = Data bits (7 or 8) b = Parity (N for None, O for Odd, E for Even) c = Stop bits (1 or 2) The factory default setting is 4800 baud, 8 data bits, no parity, 1 stop bit
(Example: 4800 8N1). NOTE: 7N1, 8O2, and 8E2 are invalid communication settings and are not supported by the transceiver. BUFF [ON, OFF]
This command sets or displays the received data handling mode of the radio. The command parameter is either ON or OFF. The default is ON. The setting of this parameter affects the timing of how received RF data is sent out the INTERFACE connector. Outgoing (transmitted) data is not affected by this setting. If data buffering is OFF, the radio operates with the lowest possible average latency. Data bytes are thus sent out the INTERFACE port as soon as an incoming RF data frame is disassembled. Average and typical latency will both be below 10 ms, but idle character gaps may be intro-
duced into the outgoing data flow. MDS 05-3447A01, Rev. F MDS 1710A/C and MDS 2710A/C/D 23 If data buffering is ON, the radio operates in seamless mode. Data bytes will be sent over the air as quickly as possible, but the receiver buffers
(stores) the data until enough bytes have arrived to cover worst-case gaps in transmission. This mode of operation is required for protocols such as MODBUS that do not allow gaps in their data transmission. Note that seamless mode (BUFF ON) is intended only for applications where the transmitters baud rate is greater than or equal to the receivers baud rate. Adherence to this rule is left up to the user. CKEY [ONOFF]
The CKEY command enables or disables the continuously-keyed func-
tion of the radio. When CKEY is set to ON, the radio is continuously keyed. CTS [0255]
The CTS (clear-to-send) command selects or displays the timer value associated with the CTS line response. The command parameter ranges from 0 to 255 milliseconds. For DCE operation, the timer specifies how long to wait after the RTS line goes high, before the radio asserts CTS and the DTE can transmit the data. A CTS value of zero keys the radio and asserts the CTS line immediately after the RTS line goes high. For CTS Key operation (see DEVICE command), the timer specifies how long to wait after asserting the CTS, before sending data out the DATA INTERFACE port. A timer value of zero means that data will be sent out the data port without imposing a key-up delay. (Other delays may be present based on selected radio operating parameters.) DATAKEY [ON, OFF]
The DATAKEY command sets or displays the ability of the radio to key the transmitter as data is received at the DATA INTERFACE connector. Asserting RTS keys the radio regardless of this command setting. If DATAKEY is set to ON, the radio will key when a full data-character is received at the transceivers DATA INTERFACE connector. If DATAKEY is set to OFF, the radio needs to be keyed by asserting either the RTS or PTT signal or with the CKEY or KEY command. DEVICE [DCE, CTS KEY]
The DEVICE command sets or displays the device behavior of the radio. The command parameter is either DCE or CTS KEY. 24 MDS 1710A/C and MDS 2710A/C/D MDS 05-3447A01, Rev. F The default selection is DCE. In this mode, CTS will go high following RTS, subject to the CTS programmable delay time. If the DATAKEY com-
mand is set to ON, keying can be stimulated by the input of characters at the data port. Hardware flow control is implemented by signaling the CTS line if data arrives faster than it can be buffered and transmitted. If CTS KEY is selected, the radio is assumed to be controlling another radio. The RTS line is ignored and the CTS line is used as a keyline con-
trol for the other radio. CTS is asserted immediately following the receipt of RF data, but data will not be sent out the DATA INTERFACE port until after the CTS programmable delay time has expired. (This gives the other radio time to key.) DKEY This command deactivates the transmitter after it has been keyed with the KEY command. DLINK [ON/OFF/xxxx]
This command is used to configure the local diagnostic link protocol used in network-wide diagnostics. Entering DLINK ON enables the diagnostic link. Entering DLINK OFF dis-
ables the diagnostic link. To change the diagnostic link, enter DLINK followed by one of the fol-
lowing baud rates: 1200, 2400, 4800, 9600, 19200 (default). DMGAP [xx]
The DMGAP command sets the amount of time in milliseconds to wait after the receipt of a character before interpreting the next received char-
acter as the start of a new message. When data port baud rates are slow, the gap between characters within a poll may be so long that the radio interprets the next character as the start of a new poll. When diagnostics is being performed using passive messaging (see Performing Net-
work-Wide Remote Diagnostics on page 34), this command may be used to change this behavior. DTYPE [NODE/ROOT]
This command establishes the local radio as a root radio or node radio for network-wide diagnostics. Entering DTYPE NODE configures the radio as a node radio. Entering DTYPE ROOT configures the radio as a root radio. Entering the DTYPE command alone displays the current setting. See Performing Network-Wide Remote Diagnostics on page 34. Two associated commands are GATE and PEER. See MDS Network-Wide Diagnostics System Handbook (MDS P/N 05-3467A01) for details. MDS 05-3447A01, Rev. F MDS 1710A/C and MDS 2710A/C/D 25 DUMP This command displays all the programmed settings of the radio. The HHT display is too small to list all the command settings at one time. Therefore, this command is most useful if the command is issued from a computer or full-screen terminal. HREV This command displays the transceivers hardware revision level if it has been programmed at the factory. INIT The INIT command is used to re-initialize the radios operating parame-
ters to the factory defaults. This may be helpful when trying to resolve configuration problems that may have resulted from the entry of one or more improper command settings. Entry of this command allows you to get back to a known working state. The following changes to the radio are made when INIT is entered:
CTS is set to 0 DATAKEY is set to ON DEVICE is set to DCE PTT is set to 0 SCD is set to 0 TOT is set to 30 seconds and set to ON PWR is set to +37 dBm (5 watts) All other commands stay at their previously established settings. INIT [2710]
This command sets the transceiver for operation outside the MDS model P-20 chassis by setting the following parameters as shown. ASENSE AMASK RXTOT ACTIVE HI FFFF FFFF (assert alarm output on all alarms) NONE (receive time-out timer disabled) This command can be used subsequent to using the INIT 2720 command to restore the standard transceiver defaults. INIT [2720]

ASENSE AMASK RXTOT ACTIVE LO FFFF 0000 (trigger on major alarms) 20 (20 minute time-out timer) 26 MDS 1710A/C and MDS 2710A/C/D MDS 05-3447A01, Rev. F KEY This command activates the transmitter. See also the DKEY command. MODEL This command displays the radios model number code. MODEM [xxxx, NONE]
This command selects the radios modem characteristics. Enter 9600 or 3200 for digital operation, or enter NONE to select analog operation. For MDS 1710 digital operation the proper settings are 9600 for the MDS 2710A, 19200 for the MDS 1710C. For MDS 2710 operation, the proper settings are 3200 for the MDS 2710D, 9600 for the MDS 2710A, and 19200 for the MDS 2710C. OWM [XXX...]

This command sets or displays the key-up delay in milliseconds. This timer specifies how long to wait after the radio receives a key signal from either the PTT or RTS lines (on the DATA INTERFACE), before actu-
ally keying the radio. PWR [2037]
NOTE: This function may not be available, depending on certification requirements in a particular country. This command displays or sets the desired RF forward output power set-
ting of the radio. The PWR command parameter is specified in dBm and can range from 20 through 37. The default setting is 37 dBm (5 watts). To read the actual (measured) power output of the radio, use the SHOW PWR command. A dBm-to-watts conversion chart is provided in Section 7.6. MDS 05-3447A01, Rev. F MDS 1710A/C and MDS 2710A/C/D 27 RSSI This command continuously displays the radios Received Signal Strength Indication (RSSI) in dBm units, until you press the Enter key. Incoming signal strengths from 50 dBm to 120 dBm can be read. RTU [ON/OFF/0-80]
This command re-enables or disables the radios internal RTU simu-
lator, which runs with MDS proprietary polling programs (poll.exe and rsim.exe). The internal RTU simulator is available whenever a radio has diagnostics enabled. This command also sets the RTU address that the radio will respond to. The internal RTU can be used for testing system payload data or pseudo bit error rate testing. It can also be helpful in isolating a problem to either the external RTU or the radio. RX [xxx.xxxxx]
This command selects or displays the radios receive frequency in MHz. The frequency step size is 6.25 kHz for the MDS 2710A/C and 5.0 kHz for the MDS 2710D. If the customer frequency has not been programmed at the factory, a default frequency will be programmed in the radio near the center of the frequency band. RXTOT [NONE, 1-255]
The RXTOT command selects or displays the receive time-out timer value in minutes. This timer triggers an alarm (event 12) if data is not detected within the specified time. Entering the RXTOT command without a parameter displays the timer value in minutes. Entering the RXTOT command with a parameter ranging from 0 to 255 resets the timer in minutes. Entering the RXTOT command with the parameter NONE disables the timer. SCD [0-255]
This command displays or changes the soft-carrier dekey delay in milli-
seconds. This timer specifies how long to wait after the removal of the keying signal before actually releasing the transmitter. A value of 0 millisec-
onds will unkey the transmitter immediately after the removal of the keying signal. SER This command displays the radios serial number as recorded at the fac-
tory. 28 MDS 1710A/C and MDS 2710A/C/D MDS 05-3447A01, Rev. F SHOW [DC, PORT, PWR]
The SHOW command displays different types of information based on the command variables. The different parameters are:
DCDisplay DC input/output voltages PORTDisplay the connector port (RJ-11 or DB-25) that is active for diagnostics and control. PWRDisplay RF power output SNR This command continuously displays the signal-to-noise ratio of the received signal expressed in dB, until you press the Enter key. As used in this guide, the signal-to-noise measurement is based upon the signal level following equalization, for received frames. The SNR is an indication of the received signal quality. The SNR indi-
cation ranges from 10 dB to 33 dB. A value of 10 dB represents a very poor signal. A value of 24 dB represents a very good signal. When the SNR command is used, it causes the DIAG. port to enter an update mode, and the signal-to-noise ratio is updated and redisplayed every 2 seconds. The SNR continuously updates until the pressed. ENTER key is SREV This command displays the software revision level of the transceiver firmware. STAT This command displays the current alarm status of the transceiver. If no alarms exist, the message NO ALARMS PRESENT appears at the top of the HHT display. If an alarm does exist, a two-digit code (0031) is displayed and the alarm is identified as Major or Minor. A brief description of the alarm code is also given. If more than one alarm exists, the word MORE appears at the bottom of the screen and additional alarms are viewed by pressing the key. Detailed descriptions of event codes are provided in Table 8 on page 32. ENTER TEMP This command displays the internal temperature of the transceiver in degrees Celsius. MDS 05-3447A01, Rev. F MDS 1710A/C and MDS 2710A/C/D 29 TOT [1-255, ON, OFF]
This command sets or displays the transmitter Time-out Timer value
(1255 seconds), as well as the timer status (ON or OFF). If the timer is on, and the radio remains keyed for a longer duration than the TOT value, the transmitter is automatically unkeyed. When this happens, the radio must be commanded back to an unkeyed state before a new keying command is accepted. The default timer value is 30 seconds. TX [xxx.xxxxx]
This command selects or displays the radios transmit frequency in MHz. The frequency step size is 6.25 kHz for the MDS 2710A/C and 5.0 kHz for the MDS 2710D. If the customer frequency has not been programmed at the factory, a default frequency will be programmed in the radio near the center of the frequency band. UNIT [10000...65000]
This command selects or displays the radios unit address. The factory default setting is the last five digits of the transceivers serial number. The unit address is used in network diagnostics. See MDS Net-
work-Wide Diagnostics System Handbook (MDS P/N 05-3467A01) for more information. 6.0 TROUBLESHOOTING Successful troubleshooting of the radio system is not difficult, but it requires a logical approach. It is best to begin troubleshooting at the master station, as the rest of the system depends on the master for polling commands. If the master station has problems, the operation of the entire network can be compromised. It is good practice to start by checking the simple things. For proper operation, all radios in the network must meet these basic requirements:
Adequate and stable primary power. The radio contains an inter-
nal self-resetting fuse (4A). Remove and re-apply primary power to reset. Secure connections (RF, data and power) An efficient and properly aligned antenna system with a good received signal strength (at least 90 dBm). It is possible for a system to operate with weaker signals, but reliability will be degraded. Proper programming of the transceivers operating parameters
(see Section 5.0, TRANSCEIVER PROGRAMMING). 30 MDS 1710A/C and MDS 2710A/C/D MDS 05-3447A01, Rev. F The correct interface between the transceiver and the connected data equipment (correct cable wiring, proper data format, timing, etc.) 6.1 LED Indicators The LED status indicators are an important troubleshooting tool and should be checked whenever a problem is suspected. Table 5 on page 16 describes the function of each status LED. 6.2 Event Codes When an alarm condition exists, the transceiver creates a code that can be read on an HHT connected to the DIAG. port. These codes can be very helpful in resolving many system difficulties. Refer to Table 8 for a def-
inition of the event codes. Checking for AlarmsSTAT command To check for alarms, enter STAT on the HHT. If no alarms exist, the mes-
sage NO ALARMS PRESENT appears at the top of the display (Figure 11). Invisible place holder Figure 11. HHT Display in Response to STAT Command If an alarm does exist, a two-digit alarm code (0031) is displayed and the event is identified as a Major or Minor Alarm. A brief description of the alarm is also given. If more than one alarm exists, the word MORE appears at the bottom of the screen. To view additional alarms, press ENTER
. Major Alarms vs. Minor Alarms Major Alarmsreport serious conditions that generally indicate a hard-
ware failure, or other abnormal condition that will prevent (or seriously degrade) further operation of the transceiver. Major alarms generally indicate the need for factory repair. Contact MDS for further assistance. MDS 05-3447A01, Rev. F MDS 1710A/C and MDS 2710A/C/D 31 Minor Alarmsreport conditions that, under most circumstances will not prevent transceiver operation. This includes out-of-tolerance condi-
tions, baud rate mismatches, etc. The cause of these alarms should be investigated and corrected to prevent eventual system failure. Event Code Definitions Table 8 contains a listing of all event codes that may be reported by the transceiver. Table 8.

(polling which briefly interrupts payload data transmission) can be per-
formed. To perform diagnostics without interrupting payload data trans-
mission, connect the PC to a radio defined as the root radio. A radio is defined as a root radio using the DTYPE ROOT command locally, at the radio. A complete explanation of remote diagnostics can be found in MDS Network-Wide Diagnostics System Handbook (MDS P/N 05-3467A01). See the Handbook for more information about the basic diagnostic procedures outlined below. 1. Program one radio in the network as the root radio by entering the DTYPE ROOT command at the radio. 2. At the root radio, use the DLINK ON and DLINK [baud rate] commands to congure the diagnostic link protocol on the RJ-11 port. MDS 05-3447A01, Rev. F MDS 1710A/C and MDS 2710A/C/D 35 3. Program all other radios in the network as nodes by entering the DTYPE NODE command at each radio. 4. Use the DLINK ON and DLINK [baud rate] commands to congure the diagnostic link protocol on the RJ-11 port of each node radio. 5. Connect same-site radios using a null-modem cable at the radios diagnostic ports. 6. Connect a PC on which MDS InSite software is installed to the root radio, or to one of the nodes, at the radios diagnostic port. (This PC may be the PC being used to collect payload data, as shown in Figure 12.) To connect a PC to the radios DIAG. port, an RJ-11 to DB-9 adapter
(MDS P/N 03-3246A01) is required. If desired, an adapter cable may be constructed from scratch using the information shown in Figure 13. Invisible place holder RJ-11 PLUG

(See the MDS InSite Users Guide for instructions.) 7.3 Bench Testing Setup Figure 14 shows a sample test setup that can be used to verify the basic operation of transceivers in a shop setting. The test can be performed with any number of remote radios by using a power divider with the required number of output connections. The RTU simulator shown in the test setup (MDS Part No. 03-2512A01) is a microcontroller that emulates a remote terminal unit operating at 1200, 2400, 4800, or 9600 bps. Custom software is supplied with the RTU simulator that allows continuous polling of remote radios using an IBM-compatible personal computer. The software reports the number of polls sent, polls received, and the number of errors detected. As an alternative to using an external RTU simulator, the transceivers internal RTU simulator may be used (see RTU command in Table 7 on page 20). (This will not provide as conclusive a test as an external sim-
ulator because it does not utilize the transceivers data connector.) 36 MDS 1710A/C and MDS 2710A/C/D MDS 05-3447A01, Rev. F NOTE: It is very important to use attenuation between all units in the test setup. The amount of attenuation required will depend on the number of units being tested and the desired signal strength
(RSSI) at each transceiver during the test. In no case should a signal greater than 50 dBm be applied to any transceiver in the test setup. Invisible place holder COMPUTER RUNNING MDS

Typical setup for bench testing of radios 7.4 Helical Filter Adjustment If the operating frequency of the radio is changed significantly, the helical filters should be adjusted for maximum received signal strength
(RSSI). To adjust the filters, proceed as follows:
1. Remove the top cover from the transceiver by loosening the four screws and lifting straight up. 2. Locate the helical lters on the PC board. See Figure 15. 3. Apply a steady signal to the radio at the programmed receive fre-
quency (80 dBm level recommended; no stronger than 60 dBm). This can be done with a signal generator or an over-the-air signal. 4. Measure the radios RSSI using one of the following methods:
With an HHT (See Section 5.0, TRANSCEIVER PROGRAM-
MING on page 17). With MDS Radio Configuration Software (See Section 7.5, Upgrading the Radios Software on page 38). With a voltmeter connected to Pin 21 of the DATA INTERFACE connector (See Section 4.2, RSSI Measurement on page 16). MDS 05-3447A01, Rev. F MDS 1710A/C and MDS 2710A/C/D 37 5. With a non-metallic adjustment tool, adjust each section of the helical lter for maximum RSSI. Re-install the cover to the trans-
ceiver. Invisible place holder FRONT PANEL OF RADIO U104 U101 SHIELD COVER U202 U203 HELICAL ADJUSTMENTS J301 Figure 15. Helical Filter Location 7.5 Upgrading the Radios Software From time to time, new product features or software maintenance files may become available from MDS. This section describes the steps nec-
essary to install new software into the transceiver using a PC connected to the radios DIAG. port. Upgrade software can be obtained in a number of ways. The MDS Web site at www.microwavedata.com contains an FTP area with software files for several radio models. You can browse the listings to see if there are files pertaining to your particular model. There is no charge for this service. In addition, you can also contact MDS to request radio software. Soft-
ware files may be sent to you via e-mail, or on a 3.5 diskette. There may be a nominal charge for the software depending on the nature of the upgrade. NOTE: Software upgrades are distributed as ASCII files with a .S28 extension. These files use the Motorola S-record format. 38 MDS 1710A/C and MDS 2710A/C/D MDS 05-3447A01, Rev. F Using Radio Software Upgrade Diskette A software upgrade diskette may be purchased from MDS to add new product features to the radio such as Network-wide Diagnostics. The upgrade kit includes a diskette (MDS P/N 06-3501A01) with the most current radio software, authorization codes, and an instruction booklet. Contact MDS for ordering information. When calling, please have the serial number(s) available for the radio(s) that you wish to upgrade. The upgrade software can be run on an IBM-compatible computer con-
nected to the radios DIAG. port via an RJ-11 to DB-9 adapter (MDS P/N 03-3246A01). If desired, an adapter cable may be constructed from scratch using the information shown in Figure 13. To initiate the upgrade, insert the upgrade diskette in Drive A:. Set the working directory to A: (example: from a DOS prompt type A:\). Next, type UPGRADE and press the ENTER key. (If you have the radio connected via the Com2 serial port, type UPGRADE-2 instead.) The upgrade soft-
ware will normally run automatically without any further prompts. The radios PWR LED will flash rapidly to confirm that a download is in process. The download takes about two minutes. NOTE: If a software download fails, the radio is left unprogrammed and inoperative. This is indicated by the PWR LED flashing slowly (1 second on, 1 second off). This condition is only likely if a power failure occurred to the computer or radio during the downloading process. The download can be attempted again when the fault has been corrected. Using Radio Configuration Software If you already have software that you wish to download into the trans-
ceiver, Radio Configuration Software (MDS P/N 03-3156A01) may be used to perform the installation. To use this method, proceed as follows:
Connect a PC to the radios DIAG. port via an RJ-11 to DB-9 adapter
(MDS P/N 03-3246A01). If desired, an adapter cable may be con-
structed from scratch using the information shown in Figure 13. Run the Radio Configuration software. Under the SYSTEM menu, select RADIO SOFTWARE UPGRADE. Follow the prompts and online instructions to locate the desired software and complete the upgrade. The radios PWR LED will flash rapidly to confirm that a download is in process. The download takes about two minutes. MDS 05-3447A01, Rev. F MDS 1710A/C and MDS 2710A/C/D 39 NOTE: If a software download fails, the radio is left unprogrammed and inoperative. This is indicated by the PWR LED flashing slowly (1 second on, 1 second off). This condition is only likely if a power failure occurred to the computer or radio during the downloading process.
