Microwave Data Systems MDS 9810 Installation And Operation Manual page 2

Below are the basic steps for installing the transceiver. Detailed instructions are given in "INSTALLA-
TION" on Page 14 of this guide.
1. Install and connect the antenna system to the radio
• Use good quality, low-loss coaxial cable. Keep the feedline as short as possible.
• Preset directional antennas in the direction of desired transmission.
2. Connect the data equipment to the radio's INTERFACE connector
• Connection to the radio must be made with a DB-25 Male connector. Connections for typical sys-
tems are shown below.
• Connect only the required pins. Do not use a straight-through RS-232 cable with all pins wired.
• Verify the data equipment is configured as DTE. (By default, the radio is configured as DCE.)

3. Apply DC power to the radio
• Observe proper polarity. The red wire is the positive lead; the black is negative.
4. Set the radio's basic configuration with a Hand-Held Terminal (HHT)
• Set the baud rate/data interface parameters as follows. Use the BAUD xxxxx abc command,
where xxxxx equals the data speed and abc equals the communication parameters as follows:
a = Data bits (7 or 8)
b = Parity (N for None, O for Odd, E for Even
c = Stop bits (1 or 2)
(Example: BAUD 9600 8N1 ) NOTE: 7N1, 8E2 and 8O2 are invalid data parameters.
5. Verify proper operation by observing the LED display
• Refer to Table 4 on Page 26 for a description of the status LEDs.
• Refine directional antenna headings for best received signal strength using the RSSI command.
• If difficulties are encountered, please refer to Table 14 on Page 56 for troubleshooting help.
