Hey guys. Looking to get add an MSC-400 to my system. One thing that I wanted to take advantage of is the RS232 and Video Sensor Cables. I see URC sells the VID cables and RS232 M or F cables in packs of 6. Seems kind of pricey to me since I only need a few. So I figured I could make my own alot cheaper.

One thing I noticed is that it use mini plugs to terminate into the unit with 4 pins (3 lines and a ground). So a standard stereo mini jack will not work. Are these something I can get at radio shack? I have never really seen them before.

Also, on the VID cables, does anyone know the wiring pinouts? It is using a composite video output so I assume only two of the 4 pins on the mini plugs are wired, but which two?

Thanks for any help.
