FUNCTIONAL DESCRIPTION
The Common (C) relay contact output for the Talk, Dim, Mute, and Timer Reset relays. It can be set for active
low or high logic: for an active low output jumper this pin to logic ground; for active high output, jumper
this pin to the + voltage logic supply. For isolated operation, the ground and/or logic supply should be
supplied by the peripheral device. When used with remote panels, jumper to pin 9 for active low logic or to
pin 1 for active high logic. Relay outputs can sink or source up to 60 volts at 350 mA (combined current).
A single momentary connection to Relays Common (pin 3) occurs whenever a channel resets the event
timer in the Console Display. This connection typically connects to the reset logic input on a studio or
external location event timer.
Connects to Relays Common (pin 3) while mute is active. Output is a N.O. dry contact type that is typically
used to drive a mute indicator or to mute talk and cue speakers.
Connects to Relays Common (pin 3) while dim is active. Output is a N.O. dry contact type that is typically
used to drive a dim indicator or to control a dim switch for talk and cue speakers.
Connects to Relays Common (pin 3) while receiving a Talk to External command. Output is a N.O. dry
contact type that is typically used to drive an indicator or to switch a signal to a talk speaker.
To enable the two external control inputs: Talk to C/R and Cue, tie this pin to + logic voltage (+5 to +40).
When tied to isolated devices like remote control panels, jumper to pin 8 (+5 volts) to enable the inputs.
When tied to a peripheral device, connect to the peripheral voltage pin.
While held low, routes the input designated as the External Cue Input onto the cue bus .
While held low, routes the input designated as the External Talk Audio input to the talk to C/R bus.
Console logic voltage output sources that can deliver up to 300 mA of current to isolated control panels. All
pins are simply paralleled for convenience.
Console logic ground. Should be connected to isolated control panels only.
