FUNCTIONAL DESCRIPTION OF CONNECTION
When activated, adds the External Cue input to the Cue bus. These complementary logic inputs r5 to +40
VDC on the (+) input and ground on the (-) input for activation. This can be done by connecting an active high
logic to the (+) input and grounding the (-) input, or by sup5 to +40 VDC to the (+) input and an active
low logic to the (-) input.
Module logic voltage output source that can deliver up to 300 mA of current. Use only on isolated ground
devices like a control panel.

CONTROL ROOM MODULE — CUE CNTL
This 8-pin connector controls whether the Ex-
ternal Cue audio input feeds the Cue bus.
To route the External Cue audio to Cue us-
ing a remote panel, jumper pin 3 (Cue +) to pin
4 (Logic 5VDC). Connect a single pole
switch to Pin 2 (Cue -) and pin 1 (Logic
Ground).
If an external device (like a Digital Delivery
System) is used to trigger the External Cue, do
not connect to pins 1 and 4. All logic voltages
and ground must come from the external de-
vice. For low logic, connect the logic signal to
pin 2 and a voltage source to pin 3. For high
logic, connect the logic signal to pin 3 and tie
pin 2 to logic ground.
