Note: This guide begins after the displays have been physically mounted.
General Radio Setup
1. Choose a location for installation with a clear-line-
of-sight between the radios, with no obstructions or
interference. Refer to Figure 1.
2. Set the same channel inside both radios. Refer to the
radio manual for additional information.
Server Radio Installation
1. Mount the J-box/signal converter near a 120 VAC
outlet.
2. Mount the server radio on the outside of the
building within line of sight of the client radio.
3. Connect power/signal cables as follows. The letter
for each step is noted in Figure 2. Grease each signal
jack with electrical contact grease before making the
following signal connections.
a. At the J-box, connect the 6-conductor, 18 AWG
stranded cable at the terminal plug labeled "RS-
422 to Radio."
b. Run the cable from the J-box through conduit to
the server radio. The maximum distance from
the J-box to the server radio is 1,000 feet (450
meters).

At the server radio, connect the wires to the
terminal plug labeled "TB2 (RS-422 IN)" as
