INTRODUCTION This guide presents basic installation and operating instructions for the MDS SD9 Series wireless transceiver. The transceiver (Figure 1) is designed to operate in point-to-multi-

point environments, including utility automation/distribution systems, and other telemetry functions. These radios are software-configurable to provide flexible operation in a variety of applications using one hardware platform. They employ microprocessor control and Digital Signal Processing (DSP) tech-

nology to provide robust communications even under adverse condi-

tions. Figure 1. SD9 Data Transceiver The transceiver is designed for trouble-free operation with data equip-

ment provided by other manufacturers, including remote terminal units (RTUs), programmable logic controllers (PLCs), flow com-

puters, transaction terminals, and similar devices. NOTE:

Some features may not be available on all units, based on the options purchased and the applicable regulatory constraints for the region in which the radio will operate. Front Panel Connectors Figure 2 shows the interface connectors and indicators on the trans-

Adequate and stable primary power Secure connections (RF, data and power) A clear transmission path between stations An efficient and properly aligned antenna system providing adequate received signal strength. Proper programming of the transceivers operating parameters The correct interface between the transceiver and the connected data equipment (correct cable wiring, proper data format, tim-

ing, etc.) LED Indicators The LED status indicators (Figure 7) are an important troubleshooting aid and should be checked whenever a problem is suspected. Table 3 describes the function of each status LED on the top panel of the radio. In addition to the top panel LEDs, the connector has two integrated LEDs. A steady green LED indicates that an Ethernet link has been established, a flashing green indicates data activity, and a yellow LED indicates 100 Mbps operation. ETHERNET/LAN 05-xxxxA01, Rev. 01 MDS SD9 Startup Guide 9 Invisible place holder Figure 7. LED Indicators Table 3.

FlashingData is being transmitted and received. OffLAN not detected or excessive traffic is present. COM1/COM2 The COM LEDs show activity on the serial payload data port(s). The left LED shows TX data and the right one shows RX data. LINK When lit, indicates that a communication link is established with the master station. Event Codes When an alarm condition exists, the transceiver creates a code that can be read on a connected terminal. These codes can be helpful in resolving many system difficulties. Refer to Table 4 (Page 11) for a definition of the event codes. STAT command Checking for Alarms To check for alarms, connect a terminal to the radios

(diagnos-

tics) connector. See COM1 CONNECTIONS on Page 12 for pinout information. COM1 STAT Enter NO ALARMS PRESENT appears on the display. on the connected terminal. If no alarms exist, the message 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. 10 MDS SD9 Startup Guide 05-xxxxA01, Rev. 01 If more than one alarm exists, the word MORE appears on the screen. To view additional alarms, press ENTER

. Major Alarms vs. Minor Alarms Major Alarmsreport serious conditions that generally indicate a hardware failure, or other abnormal condition that will prevent (or seriously hamper) further operation of the transceiver. Major alarms generally indicate the need for factory repair. Contact your factory representative for assistance. Minor Alarmsreport conditions that, under most circumstances will not prevent transceiver operation. This includes out-of-tolerance con-

ditions, baud rate mismatches, etc. The cause of these alarms should be investigated and corrected to prevent system failure. Event Code Definitions Table 4 contains a listing of event codes that may be reported by the transceiver. The codes shown are a subset of a larger pool of codes used for various GE MDS products. For this reason, the table does not show a sequential listing of all code numbers. Only the codes appli-

cable to this product are shown. Table 4. Event Codes Event Code 01 04 08 12 13 17 Event Class Major Major Major Major Minor Minor Description Improper software detected for this radio model. The RF synthesizer is reporting an out-of-lock condition. The system is reporting that it has not been calibrated. Factory calibration is required for proper radio operation. Receiver time-out. No data received within the specified receiver time-out time. A Transmitter timeout was detected. The radio stayed keyed longer than the duration specified by the TOT command. A data parity fault has been detected on the COM2 INTERFACE connector. This usually indicates a parity setting mismatch between the radio and the RTU. 05-xxxxA01, Rev. 01 MDS SD9 Startup Guide 11 Table 4. Event Codes (Contd) Event Code 18 26 31 Event Class Minor Minor Minor Description A data framing error has been detected on the COM2 INTERFACE connector. This may indicate a baud rate mismatch between the radio and the RTU. The DC input voltage is out-of-tolerance. If the voltage is too far out of tolerance, operation may fail. The transceivers internal temperature is approaching an out-of-tolerance condition. If the temperature drifts outside of the recommended operating range, system operation may fail. Internal Spectrum Analyzer The radio contains a built-in spectrum analyzer tool that can be dis-

played on a connected PC. The tool is helpful in diagnosing interfer-

ence problems on or near your channel frequency. Access the spectrum analyzer by entering spectrum at the command prompt. A display appears showing detected signals on your current channel. Optionally, you can specify a frequency at the command prompt to view the surrounding spectrum of that frequency. To do this, enter spectrum xxx.xx, where xxx.xx is the frequency in MHz. The display creates a received signal strength indication (RSSI) vs. frequency plot for the frequency and surrounding signals. By ana-

lyzing the display, you can determine the presence of other signals near the transceivers operating frequency. This information can be helpful in troubleshooting interference problems. COM1/COM2 REFERENCE COM1 CONNECTIONS The COM1 connector is used to connect a PC to the radio for manage-

ment or diagnostics. A straight-through cable is required that connects Pin 2 (RXD), Pin 3 (TXD), and Pin 5 (Ground). (See Figure 8.) 12 MDS SD9 Startup Guide 05-xxxxA01, Rev. 01 DB-9 MALE

COM2 CONNECTIONS The COM2 connector (Figure 9) is used to connect the radio to an external DTE telemetry device that supports the EIA/RS-232 or EIA/RS-485 (balanced) format, depending on how the radio is config-

ured. The radio supports data rates of 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 bps (asynchronous data only). The COM2 connector mates with a standard DB-9 plug that is avail-

able from many electronics parts distributors. Table 5 provides detailed pin descriptions for the COM2 data connector in RS/EIA-232 mode.
