Installation:
In addition to the RJ45 interconnect cables on the front panel, the +9.5 Vdc power and ground must be connected
on the back panel. Figure 1 shows a diagram of the back panel of the CI-RC-4M-G2.
Figure 1:CI-RC-4M-G2 Back Panel
A female DB25 connector on the back of the subrack (J12) can be used for connectioning to the CI-RC-4M-G2
using a standard straight-through male-to-male DB25 cable. The A-PNL-AUX96-3 auxiliary connector can also be
used to connect to the CI-RC-4M-G2, as shown in Figure 2. The information in brackets is the function that uses
that particular connection. For example, if you are using CTCSS tones, the Rx Disc O/P must be connected. The
diagram only shows connections for Receiver and Transmitter A.
