help with pin outs on DC input, Sony CCTV Cam CV-710 NDC

[titan32]

Have a 6-pin mini DIN connector on the camera, and need to wire the mating connnector (from a 12vDC supply).

Have determined the chassis ground, but am unsure of the rest. Have 76 ohms across the ground pin and 2 separate pins. Open loop on the rest of the pins. Is the safe bet that the two pins reading 76 ohms need the 12vdc?

It is more likely that the pins with 76 ohms to ground are inputs for horizontal and vertical sync.

The power supply pin has probably a polarity protection diode or something similar in series, so it will appear open circuit to a DMM set for resistance measurement.

Operation manuals for Sony cctv cameras where the connector pinout is described are generally easily available on the web, just spend a few minutes googling for a manual.
