ATTENTION! The device has no built-in Infrared receiver and transmitter. For the complete usage attach
an IR emitter unit to the IR OUT and an IR detector unit to the IR IN connectors.
Infrared (IR) receiver and transmitter options can be found on this tab. There are three submenus available
under it: IR codes, Ports, and Clear all IR codes.
IR Codes #infra #infrared
The user can set the name of the IR code, the fingerprint (hash), and the repeat timeout in ms, and actions
can be ordered to each IR code as well.
