Troubleshooting The IR Interface

If you are not receiving command acknowledgments from the IR transmitter, make sure the IR transmitter

is sending commands. One easy way to test this is to point the IR transmitter at a video camera and see if

the IR transmissions light up on the display screen.

The next step is to make sure the IR receiver is wired properly and terminated to the IR receive port on the

SoundStructure rear-panel as shown in the following figure.

By default the SoundStructure device is configured for the Polycom IR remote to have the default device ID

of 3 for the SoundStructure to detect the IR key presses.

Make sure there is an IR receiver virtual channel defined as follows:

vcdef "IR input" control ir_in 1

so that when the IR signal is received, there is a command acknowledgment from the IR controller received

and reported back as:

val ir_key_press "IR Input" 58

The key press values returned correspond to the mapping on the Polycom IR remote controller as specified

Integrator's Reference Manual for Polycom HDX Systems.
