MODULE CONTROL PORTS
The following logic functions, listed by pin number, are available at the logic
port of each IN-60 module:
(1) REMOTE ON - connected momentarily to DIGITAL COMMON to turn
channel on from a remote location.
(2) REMOTE OFF - connected momentarily to DIGITAL COMMON to turn
channel off from a remote location.
(3) ON TALLY - permits a 5V lamp to be controlled by the
module’s channel ON circuit.
(4) MACHINE COMMON - is provided so that remote machine START
and STOP can function without the need to tie the console
common and the remote machine common together.
(5) REMOTE STOP - allows a remote machine to be stopped by
pushing the module’s channel OFF button.
(6) REMOTE START - allows a remote machine to be started by
pushing the module’s channel ON button.
(7) READY - allows a remote machine to control the module’s
channel OFF switch indicator lamp. The LOCAL OFF ENABLE
dipswitch must be in the OFF position.)
(8) COUGH - provides a remote momentary OFF function.
(9) TALKBACK - a continuous contact closure from this line to
digital common places the module in CUE. If the module’s
CUE ENABLE dipswitch is activated, the CUE bus signal is
sent to the headphones, and to the control room speakers if
so programmed at the CR/SC dipswitch.
(10) LOGIC FOLLOW - provides a logic high of 5V when the module’s A
inputs are selected. The signal is used to light an LED
indicator or otherwise used to develop A/B follow logic
functions.
(11) +5 VOLTS - provides power source for external circuitry.
(12) DIGITAL COMMON - provides power return for external
circuitry.
For controlling “on-air” tally functions, a relay closure is provided. This
closure is available at 12 pin connector "CT34" in the control room section of
the mainframe motherboard.
Refer to the Module I/O pinout text and wire the IN-60 logic connectors.
Typically, a mic channel will use the REMOTE ON, REMOTE OFF, ON TALLY,
COUGH, and TALKBACK signals, along with +5 VOLTS and DIGITAL COM-
MON. A line input will use REMOTE ON, REMOTE OFF, ON TALLY, REMOTE
START, REMOTE STOP, and READY, along with +5 VOLTS, DIGITAL COM-
MON, and MACHINE COMMON. The schematic diagram ("Typical IN-60
Remote Logic"; next page) shows typical connections for both mic and line
inputs.
