Top panel: IR learning sensor
In most cases, Extron has already produced an IR driver file for controlling the
projector or display you plan to use. If a device driver file is not available, you can
create your own using Extron IR Learner software, the projector or display’s remote
control, and the MLC’s IR learning receiver sensor, shown below.
