![2 MDS SD Series Quick Start Guide (x710 Mode) 05-4692A01, Rev. 03 (FCC)Figure 4). Strip the wire leads to 6 mm (1/4 inch) and insert them into the wire ports. Be sure to observe proper polarity as shown below. Tighten the binding screws securely.Figure 4. DC Power ConnectorCAUTION:The unit is designed for use with negative-groundsystems only. The power supply should be equippedwith overload protection (NEC Class 2 rating), toprotect against a short circuit between its output termi-nals and the radio’s power connector.5. Set the radio’s configuration. Connect a PC to the radio’s COM1 port as shown in Figure 5. A straight-thru cable may be used for this connection.NOTE: Consult your System Administrator if you are unsure ofthe settings required for your network.Figure 5. Setup for PC Configuration2.1.1 Software ConfigurationThere are two methods for communicating with the radio for con-figuration and management: Serial (COM1 DB9 connector) and Telnet (ETHERNET RJ-45 connector). Both present identical functionality, but the method of access is different for each. The focus here is on Serial access, but Telnet may be used by following these additional points, which replace Steps 1 and 2 below:• For Telnet, connect to the radio with a PC that is on the same IP network as the transceiver. Launch a Telnet pro-gram, and connect to the radio using its programmed IP address. • The default IP address is 192.168.1.1. If you do not know the IP address of the radio, use the serial configuration steps below to view the address with the IPCONFIG command.1. With a PC connected to the COM1 serial port, launch a terminal program, such as HyperTerminal (included with most pre-Vista Windows®-based PCs) and set the following parameters: 8 bits, no parity, one stop bit (8N1), flow control disabled, VT100 emulation. The radio’s COM1 port automatically determines the connected baud rate (within the range of 1200–115200 bps).2. Press the key followed by a series of keypresses (1/2 second intervals) until the > prompt appears. The radio is now ready to accept commands.3. Set/verify the RX (receive) and TX (transmit) frequencies. To set the receive frequency, enter RX followed by the correct fre-quency in MHz (xxx.xxxxx). Press .To set the transmit frequency, enter TX followed by the correct frequency in MHz (xxx.xxxxx). Press .4. The factory default modem settings support operation for most systems. Other options are available using the proper soft-ware commands. The current setting may be viewed using the MODEM command. Use MODEM [xxxx] if changes are required, where xxxx represents the modem speed in bps.When finished with the steps above, review the other configu-ration options to determine if other settings are required for your system. Table 3 lists key software commands for the radio.2.2 Initial CheckoutIn-service operation of the transceiver is completely automatic. The only operator actions required are to apply DC power and observe the LEDS for proper indications. Table 1 summarizes the radio’s LED functions.2.2.1 LED FunctionsNOTE: LED labeling may vary on early units. LED position andfunctionality remains as described below.Figure 6. LED Status IndicatorsTable 1: Description of LED Status IndicatorsNOTE: The Ethernet connector also has two embedded LEDs. Aflashing green indicates Ethernet data activity, and ayellow indicates 100 Mbps operation has been achieved.2.2.2 Antenna SWR CheckBefore placing the unit in final operation, the antenna system’s standing wave ratio (SWR) should be checked using a wattmeter suited to the frequency of operation. High SWR (above 2:1) may indicate an antenna or feedline problem, and should be corrected.2.2.3 RSSI Check (for Remotes)Using the RSSI command (received signal strength indication), check for adequate signal strength. The radio must be receiving a signal from the associated Master Station (LINK LED on or blinking). In general, signal levels stronger than –80 dBm will pro-vide very reliable communication and allow for a degree of “fade margin.”Optimize the RSSI at Remotes by slowly adjusting the direction of the station antenna. Watch the RSSI indication for several seconds after making each adjustment so that the RSSI accurately reflects any change in the signal strength. With RSSI, the less negative the number, the stronger the incoming signal (i.e., -70 dBm is stronger than -80 dBm).All radios in the network must meet the following basic require-ments for proper operation. Check these items first when trouble-shooting a communication problem:• Adequate and stable primary power• Secure cable connections (RF, data and power)• A clear transmission path between Master and each RemotePC Running Terminal SessionTransceiverDB-9M to COM1 PortESCAPEENTERENTERENTERLED Name DescriptionPWR • Continuous—Power applied, no problems detected.• Rapid flash (5x-per-second)—Alarm indication.LAN • Flashing—Ethernet data activity is detected.• Off—Ethernet signals not detected, or excessive traffic is present at the port.DATA1/DATA2 These LEDs show data activity on the DB-9 serial payload port(s).LINK When lit, indicates that a communication link exists with the master station.3.0 TROUBLESHOOTING](https://usermanual.wiki/GE-MDS/DS-SD2/User-Guide-1205395-Page-2.png)
