Transceiver Mounting Bracket Dimensions Using screws longer than 1/4 inch (6 mm) may damage the unit’s internal PC board. 2. Install the antenna and feedline for the station. Aim directional antennas toward the master station. The antenna used with the transceiver must be designed to operate in the radio’s frequency band, and be mounted in a location that provides a clear path to the associated master station. Use low loss coaxial feedline and keep the cable as short as possible.3. Connect the data equipment to COM2 on the front panel. The radio is wired as a DCE device. Most applications will require the use of a straight-thru cable. Check Table 5 on Page 13 for pin details. Note: The LAN/Ethernet port is used for upgrading the radio’s firmware. Refer to the Reference Manual for usage details. 4. Connect primary power to the transceiver. Power applied must be within 10.5–16 Vdc and capable of continuously providing up to 2 Amperes. A power connector with screw-terminals is pro-vided with each unit (see Figure 5). Strip the wire leads to 6 mm (1/4 inch) and insert in the wire ports.

10 MDS SD4 Startup Guide 05-4669A01, Rev. A Event CodesWhen 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.Checking for Alarms—STAT commandTo check for alarms, connect a terminal to the radio’s COM1 (diagnos-tics) connector. See “COM1 CONNECTIONS” on Page 12 for pinout information. Enter STAT on the connected terminal. If no alarms exist, the message NO ALARMS PRESENT appears on the display.If an alarm does exist, a two-digit alarm code (00–31) 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 on the screen. To view additional alarms, press .Major Alarms vs. Minor AlarmsMajor Alarms—report 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 Alarms—report 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.ENTER
05-4669A01, Rev. A MDS SD4 Startup Guide 11Event Code DefinitionsTable 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. Internal Spectrum AnalyzerThe radio contains a built-in spectrum analyzer tool that can be dis-played on a connected PC. This utility is helpful in diagnosing inter-ference problems, or for use during initial setup of the radio. Table 4. Event Codes Event CodeEvent Class Description01 Major Improper software detected for this radio model.04 Major One or both of the internal programmable synthesizer loops is reporting an out-of-lock condition.08 Major The system is reporting that it has not been calibrated. Factory calibration is required for proper radio operation.12 Major Receiver time-out. No data received within the specified receiver time-out time.17 Minor 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.18 Minor 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.26 Minor The DC input voltage is out-of-tolerance. If the voltage is too far out of tolerance, operation may fail.31 Minor The transceiver’s internal temperature is approaching an out-of-tolerance condition. If the temperature drifts outside of the recommended operating range, system operation may fail.
12 MDS SD4 Startup Guide 05-4669A01, Rev. A The spectrum analyzer display is accessed by entering spectrum xxx.xx x.x at the command prompt, where the x characters denote the center frequency and span frequency, respectively. The frequencies are entered in megahertz. For example, a sample entry would be spectrum 410.00 1.5, corresponding to a center operating frequency of 410.00 MHz and a span (sweep width) of 1.5 MHz.A sample display with these parameters is shown in Figure 8. The dis-play creates a received signal strength indication (RSSI) vs. frequency plot for the center frequency and all surrounding signals within the span. By analyzing the display, you can determine the presence of other signals near the transceiver’s operating frequency. Refer to the SD4 Reference Manual for additional details.Invisible place holderFigure 8. Internal Spectrum Analyzer DisplayCOM1 CONNECTIONSThe 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 9.)
