Understanding Ir Receiver Virtual Channel - Polycom SoundStructure C16 Design Manual

A control array of logic output pins may be specified with the same syntax as in the previous example
substituting digital_gpio_out for digital_gpio_in.
See Using Events, Logic, and IR
information on control array virtual channels.

Understanding IR Receiver Virtual Channel

The IR receiver input on the SoundStructure device responds with acknowledgments when a valid IR signal
is received. The first step towards using the IR receiver is to define the IR receiver virtual channel. This can
be done with the following syntax:
vcdef "IR input" control ir_in 1
where 1 is the only physical channel that can be specified since there is only one physical IR receiver
channel.
Once a command from the Polycom IR remote transmitter, a command acknowledgment of the form:
val ir_key_press "IR Input" 58
is generated by the SoundStructure device when a key that corresponds to code 58 is pressed on the IR
remote transmitter. The infrared remote controller ID must be set to the factory default of 3 for the IR receiver
to properly identify the command.
See Using Events, Logic, and IR
events.
