These phoenix connectors sense presense of a positive voltage. The component video signal most likely does not provide enough voltage to trigger the RFX9600. More than likely, you will need to buy a device such as a video sensor (search ebay or google) that can take a connection to a composite video signal and, when on, can generate a small voltage to the RFX9600. I seem to recall seeing these for X-10 or xantech equipment on the web.

If your component has a switched power jack on the back such as a cable box, the ideal thing that you can use is a 9VDC adapter and then wire the output to the phoenix connector. Search this forum for +Wall +Wart and you will find a post I replied to where someone did this with a cable box that does not have discrete codes.
