QUICK START GUIDE
1.
Mount the transceiver (see
for mounting dimensions)
2.
Install and connect the antenna system to the radio
• Use only good quality, low loss coaxial cable. Keep the feedline as short as possible.
• Preset directional antennas in the direction of desired transmission/reception.
3.
Apply DC power to the radio (10–30 Vdc @ 500 mA minimum)
• Measure the voltage source before connection.
• Observe proper polarity.
• Connect power to the power connector.
4.
Set the radio’s basic configuration with a terminal (PC or HHT) connected to
the
INTERFACE
port
• Pin 23 of the INTERFACE port must be grounded to place the radio in the control and programming
mode. (See
for a cable wiring diagram.)
• Set the transmit frequency (
TX xxx.xxx
).
• Set the receive frequency (
RX xxx.xxx
).
• Set the network address (
ADDR xxx
). All radios in a given network must have the same address.
• Set/verify the data rate using the
BAUD
command. The default setting is
BAUD 9600 8N1
. (Refer to
“TRANSCEIVER PROGRAMMING” on page 14 for command details.)
5.
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.)
6.
Verify proper operation by observing the LED display
• See Table 5 on page 13 for a description of the status LEDs.
• Refine directional antenna headings for maximum receive signal strength using the
RSSI
command.
