Nick G Smith Posted May 14, 2009 Share Posted May 14, 2009 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.

Nick 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. xc_555_techmanual.pdf Link to comment Share on other sites More sharing options...
Nick G Smith Posted May 17, 2009 Author Share Posted May 17, 2009 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 Link to comment Share on other sites More sharing options...
Darko Grujicic Posted October 7, 2010 Share Posted October 7, 2010 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 Link to comment Share on other sites More sharing options...
