Chapter 3: C2 System Connections Overview

This chapter shows C2 Communications Controller system connections.

System Control

Cat-5 cable should be used for all C2 system connections including incoming phone lines,
input and output triggers, ELAN Door Stations (including camera connections), volume
controls with override and relays.
CAUTION: ALWAYS remove power to the C2 along with any other
electronics equipment prior to making any connections to or from the
C2. Set the Power Switch on the back of the C2 to the OFF
position prior to making connections.

C2 Rear Panel Connections

The following section describes connections to the C2 Communications Controller.
C2 to VMOS or VSOS Volume Controls
When connecting rotary Volume Controls with Override to the C2, simply connect "+" from
the C2's VCO connector to "VC+" of the Volume Control. Connect "-" from the C2's
VCO connector to "VC-" of the Volume Control. Cat-5 is typically used for this purpose.
CAUTION: ALWAYS remove power to the C2 along with any other
electronics equipment prior to making any connections to or from the
C2. Set the Power Switch on the back of the C2 to the OFF
position prior to making connections.
