CONNECTING AUDIO/DATA CABLES TO
THE FIM-202D
Figure 2-2: Wiring an FIM-202D to intercom panels or interfaces
RJ-45 connectors on the FIM-202D unit’s rear panel connect the unit to
audio and data inputs and outputs as shown in Figure 2-2. Figure 2-3
illustrates the standard Ethernet type CAT-5 cable pinout configuration.
The maximum length for CAT-5 cables is 10,000 feet (3 km).

COMPATIBILITY WITH FIM-102D INTERFACES
The FIM-102D and FIM-202D interfaces are not fully compatible. If
FIM-202D and FIM-102D units are used together to create a link this
will result in an audio level offset of 5dB.
