connector.
To define the operation of a relay and associate it with a button
or a digital input, use the configuration software. (Refer to the
configuration software help for setup procedures.)
Wiring the IR/S port
You can connect a display device, switcher, or one or two IR
emitters to the IR/S port. The port allows a serial or an IR
connection. (In the configuration software, this port is called
the "Serial Port" or the "IR Port", depending on how it was
configured.)
The illustration below shows how to wire the IR/S port for IR
control via an IR emitter.
