QUICK START GUIDE
Below are the basic steps for installing the transceiver. Detailed instructions are provided in “Installation
Steps” on Page 9 of this manual.
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/reception.
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 (10.5–16 Vdc @ 2.5 A minimum)
• 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 transmit frequency ( TX xxx.xxxxx ).
• Set the receive frequency (
RX xxx.xxxxx
).
• Set/verify the data rate using the
BAUD
command. The default setting is
BAUD 4800 8N1
. (Refer to
“TRANSCEIVER PROGRAMMING” on Page 17 for command details.)
5. Verify proper operation by observing the LED display
• Refer to Table 5 on Page 16 for a description of the status LEDs.
•Refine directional antenna headings for maximum receive signal strength using the
RSSI

mand.
