FUNCTIONAL DESCRIPTION OF CONNECTION
Tie this input to +5 to +40 VDC to use the Cue (-) input as the External Cue trigger. Conversely, when the Cue
(-) input is tied to ground, then this input requires a high logic voltage (+5 to +40 VDC) to add the External
Cue audio to the Cue bus.
When this input is tied to ground, then the Cue (+) input re5 to +40 VDC to activate External Cue.
Conversely, when Cue (+) is tied to +V (+5 to +40 VDC), then a low logic input to this pin adds the External
Cue audio to the Cue bus.
Module logic voltage output source that can deliver up to 300 mA of current to an isolated control panel.
Module logic ground. Should be connected to an isolated panel only.

CONTROL ROOM MODULE — CUE CONTROL LOGIC
The 8-pin CUE CNTRL connector has the Ex-
ternal Cue on/off logic. Only four pins (1 - 4)
are used on this connector.
Typically the Cue (+) pin is jumpered to Logic
5 VDC and the Cue (-) and Logic
Ground go to an External Cue switch (main-
tained SPST). The logic connector is hidden by
the meter panel in normal operation.
