I bought a Sony XC-999 for video assist . I am using the same Y cable as for a Sony Xc-75 but I am only getting a b/w image.
The hirose 12pin cable is wired to a bnc on pins 3 Video output grnd and 4 Video output signal.
Does anyone know if that is correct wiring for a colour video signal? Looks like I am only getting the luminance signal and no chroma.
Pot 4 is switched to Y/C - but seems to make no difference on either setting.

I used to have a Manuel for the XC999, I cant find it but here is the one for the XC555 which is the newer model.

Ok, I have the answer thanks to Andrew Zorawski at Az-spectrum. Anyone else who wants to use a XC-999 for video assist use the following instructions.

To get a color image for the XC 999 Pin 11 on the 12 pin Hirose connector has to be connected to +12V.

pin 1 : 0V
pin2 : +12VDC
pin 3 : Video Out
pin4 : Video GND
pin11: +12VDC

Pot 4 on VBS

Hi Nick,
I don't have any experience with video, and I'm trying to use the XC-999 for astrophotography. I do have the XC-999, but I don't have the CMA control box. From your post, and from reading the camera's manual I understood that the camera streams the video as soon as the 12V is supplied to it. Does this mean that you can use pins 3-4 and 9-10 to output Y/C signal to a S-video input? If that is the case I can make my own simple circuit to accomplish that, but I'm not sure that this is correct. Could you please provide some more info?
Thanks,
Darko
