FOR-22 4-WIRE/RADIO INTERFACE WIRING
The FOR-22 4-wire/radio interface connects two external 4-wire
circuits to the matrix. Camera intercoms, two-way radios, microwave
and satellite links, IFBs, and program audio in and out are candidates
for use with the FOR-22.
A FOR-22 interface connects to an Eclipse matrix through the two
RJ-45 connectors on the IMF-3 or IMF-102 rear panel assembly to
which the FOR-22 is connected. One RJ-45 connector is for the first
channel of the interface. The second RJ-45 connector is for the second
channel.
The user side of the FOR-22 for each channel appears on a DB-9M
connector on the rear of the IMF-3 for IMF-102 frame. Figure 4-14
shows the pinout of either one of these connectors. Each channel is
identical.

The following sections describe how to wire for the various type of
inputs and outputs available on this connector:
• External audio devices
• Call signal input
• Relay contacts.
Note: Shielded cable should be used.
External Audio Devices
Connect external audio devices to the FOR-22 ports through the two
DB-9M connectors labeled “I/O” on the rear panel. Both audio input
and output are transformer isolated. For more information on the
