QUICK START GUIDE
Below are the basic steps for installing the transceiver. See “INSTALLATION” on Page 5 of this guide for
detailed instructions.
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
• Use a DB-25 Male connector to connect to the radio. Connections for typical systems 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.xxxx
).
• Set the receive frequency (
RX xxx.xxxx
).
• Set the baud rate/data interface parameters as follows. Use the
BAUD xxxxx abc
command, where
xxxxx
equals the data speed (110–38400 bps) 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 parameters and are not supported by the transceiver.
5.
Verify proper operation by observing the LED display
• Refer to Table 7 on Page 14 for a description of the status LEDs.
• Refine directional antenna headings for maximum receive signal strength using the
RSSI
command.
