WIRING
The 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 unit is connected. One RJ-45 connector is for the
first channel of the interface. The second RJ-45 connector is for the
second channel. Figure 2-3 shows pin assignments of the RJ-45
connectors used to connect the interface to an Eclipse matrix.
Figure 2-3: Matrix to Interface Frame Wiring
The "user" side of the FOR-22 for each channel is on a DB-9M
connector on the rear of the IMF-3 or IMF-102 frame. Figure 2-4 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
