Video Sender IR Port Does Nothing
On the sender unit, what is the infrared extender port for?
That port actually does not work with anything. It was intended for our IR emitter cable, the RX539. The idea was to be able to send video and audio through the sender units and transmit IR signals from your remote controls back to the source TV or VCR. However, that part of the product was never made functional; there would need to be an IR to RF converter/sender in the Receiver, and there is not one. Instead of using that port, we recommend that you use our PowerMid units (http://www.x10.com/products/x10_pm5900.htm) for sending IR.
