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
com-
mand.
