I have never seen a pin out utilizing video- and video+ before. My first assumption would be that it's for analog video transmission, probably composite video.

Pin Function

  1. Video-
  2. Video+
  3. 74 VDC
  4. AUX+
  5. Ground
  6. AUX-
  7. RS-485 -/A
  8. RS-485 +/B

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.

  • Thank you for your response. That answers what I need to know.
