2.
Install the antenna and feedline
for the station. Aim directional
antennas toward the master station. The antenna used with the
transceiver must be designed to operate in the radio’s frequency
band, and be mounted in a location that provides a clear path to
the associated master station. Use low loss coaxial feedline and
keep the cable as short as possible.
3.
Connect the data equipment
to
COM2
on the front panel. The
radio is wired as a DCE device. Most applications will require the
use of a straight-thru cable. Check
Table 5 on Page 13
for pin
details.
Note: The LAN/Ethernet port is used for upgrading the radio’s
fi
rmware. Refer to the Reference Manual for usage details.
4.
Connect primary power to the transceiver.
Power applied must
be within 10.5–16 Vdc and capable of continuously providing up
to 2 Amperes. A power connector with screw-terminals is pro-
vided with each unit (see
Figure 5
). Strip the wire leads to 6 mm
(1/4 inch) and insert in the wire ports. Be sure to observe proper
polarity as shown in the
Figure 5
