Control Connections
These are identical for stereo line analog and digital versions of the
IND-220 module.
All control ports (except Tally B) are opto-isolated. Functions
include remote on and off, on tally, ready, and start/stop for remote
source machines. Each function is available for the A source port,
allowing it to follow the module's A source selector switch.

To Turn the Module ON & OFF from a Remote Location
In the case of stereo line input modules, “remote location” can also
refer to a remote source machine that is feeding its audio to the module
in question. A 5VDC signal, as indicated below, will activate the
module’s channel ON and OFF switches.
REMOTE ON — Activates the module’s channel ON switch.
Provide a momentary 5VDC signal between Pins 14 and 15 (Remote
On A). This will latch the module ON. Be sure to observe the polarity
as indicated above and on the pinout diagram on pages 2-10, 2-11.
REMOTE OFF — Activates the module’s channel OFF switch.
Provide a momentary 5VDC signal between Pins 16 and 17 (Remote
Off A). This will latch the module OFF. Be sure to observe the polarity
as indicated above and on the pinout diagram on pages
2-10, 2-11.
To START and STOP Remote Source Machines Using Module
ON/OFF Switches
EXTERNAL START — Hook up the remote machine’s “start”
control pins to the IND-220 module’s lower DB-25 connector control
pins: for START A wire to pins 3 and 5.
EXTERNAL STOP — Hook up the remote machine’s “stop”
control pins to the IND-220 module’s lower DB-25 connector control
pins: for STOP A wire to pins 4 and 5.
