This is our bi-directional cable that converts an S-video signal to a composite video signal and passes the color information. Composite video signal carries the brightness, color and sync information on one wire. S-Video carries the brightness and sync information on one wire and the color and sync information on another wire; each signal has a corresponding ground wire.
This cable has a 4-pin S-video female on one end and a BNC Male on the other end. It measures about 12 inches long.
