THE 3000C REAR PANEL

Figure 3 shows the Rear Panel of the 3000C Intercom. This section lists the different
connections located on the rear of the intercom, and the use of the connections.
RADIO INTERFACE JACK
A 9-Pin D-Sub connector, which provides the attachment point for the Mobile Radio
Interface Cable.
POWER CONNECTOR
A 2-Pin connector, where the Power Cable Assembly is plugged in, interfacing the 3000C
to the vehicle's power supply.
MODULAR JACKS
There are 6 modular jacks on the 3000C. These modular jacks are the connection points for
the CA Cables leading from the Intercom Unit to the Headset Modules. All 6 jacks have
intercom capabilities. Only the 3 jacks on the left (when viewed from the rear) are capable
of transmitting on the radio (as indicated by the "TX" designation on the rear panel).
AUXILIARY INPUT & OUTPUT
The Auxiliary Input and Output are 3.5mm mono (2 conductor) jacks. These are used to
bring miscellaneous audio (such as a CD or Cassette Tape Player) into, or Intercom Audio
out of, the intercom system. See page 15 in this manual for more information on the
Auxiliary In & Out Plugs.
