<p>I don't recognize this connector, but I can say that your assumption is incorrect. Video+/- isn't "two cables", it's just a way of notating the two wires (like say, signal and ground) needed for a complete circuit. The same is true for the AUX and RS485 circuits.</p>

Is This Pin-Out for S-Video or Composite Video?
