IR Receiver Virtual Channel
The IR receiver input on the SoundStructure device will respond 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 may 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 HDX IR transmitter, a command
acknowledgement of the form:
val ir_key_press “IR Input” 58
will be 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.
