FUNCTIONAL DESCRIPTION OF CONNECTION
Equivalent to a Normally Open (N/O) relay contact. A momentary “contact closure” of 220 ms is generated when
the module On button is pressed. Typically connects to the Remote Start logic input on the peripheral device.
When DS2-2 or DS4-2 is set to On, each press of the On button generates another contact closure.
Same as the Start Command Pulse, except it is initiated by the module Off button. Typically connects to the
Remote Stop or Pause logic input on the peripheral device.
Same as Start Command Pulse, except it is a maintained contact closure for as long as the module is on. Typically
connects to the Remote Start logic input on a peripheral device that cannot use a start pulse.
The Common (C) relay contact output for the three Start and Stop Command outputs. Sets whether the Start
and Stop Commands are active high (connect this pin to the logic supply voltage on the peripheral device) or
active low (connect this pin to logic ground on the peripheral device).
To enable the control inputs: On, Off, Cough, Talk/Ext Cue, tie this pin to + logic voltage (+5 to +40). When tied to
an isolated device like a mic remote panel, use the Logic 5 VDC (jumper pin 18 to pin 6, 10, 11 or 12).
When pulled low, turns the module on from off, generating a Start Pulse if DS2-3 or DS4-3 is set to On. Input is
ignored if the module is already on, unless DS2-2 or DS4-2 is set On (each press generates a Start Pulse output).
When pulled low, turns the module off from on, generating a Stop Pulse if DS2-3 or DS4-3 is set to On. Input is
ignored if the module is already off, unless DS2-2 or DS4-2 is set On (each press generates a Stop Pulse output).
When pulled low, mutes the audio from all assigned buses for as long as the Cough button is pressed.
When pulled low, and the module is set as a Mic, the input audio is muted from all output buses and only routed
to the talkback bus. When set as a Line, routes the input audio to the Cue bus while the input is low.
All Tally outputs are N/O “dry contact” type outputs. Typically used to drive indicators, the outputs can sink or
source up to 60 volts at 350 mA. The “C” or common contact for all the tallies is Tallies Common (pin 14).
This output connects to Tallies Common while the module is off when DS1-8 or DS3-8 is set to On. When
DS1-8 or DS3-8 is set to Off, then this output is controlled by the Ready logic.
This output connects to Tallies Common while the module is on.
This output connects to Tallies Common when the module is set as a Mic and the matching A or B input is
selected. When set as a Line input, the output is connected to Tallies Common while Cue is active.
The “C” relay contact for the three Tallies, it must be tied high or low to provide the return path for the Tallies.
Typically, the tally lamps are all tied to ground and Tallies Common connects to the lamp supply voltage (+5 to
+60 VDC). If the Tallies are tied to +VDC, then this pin would tie to ground.
These complementary logic inputs r5 to +40 VDC between the (+) input and 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.
When activated while the module is on, turns the module off without generating a stop pulse. When activated
while the module is off, it controls the Off lamp to indicate device status. Typically, no lamp indicates the
peripheral is not ready to play, a steady lamp on indicates the device is ready, and a flashing lamp indicates the
device has already played or is not yet cued up.
When activated while the module is on, turns the module off without generating a stop pulse. Input is ignored if
the module is already off.
Module logic voltage output sources that can deliver up to 300 mA of current to isolated control panels. All pins
are simply paralleled for convenience.
Module logic ground. Should be connected to isolated control panels only.
