Troubleshooting The IR Interface
If you are not receiving command acknowledgements 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 follow-
ing figure.
By default the SoundStructure device is configured for the HDX 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 HDX IR
remote controller as specified in the Polycom HDX Integrator’s Reference
Manual.
Contacting Technical Support
Before contacting technical support, make sure you have saved the Sound-
Structure Studio design file and also saved your log file to disk as technical
support will want to review these files while helping with the system.
