We are using an SX20 codec with the PrecisionHD 1080p4xS2. As our camera and codec are more than 3 metres apart, we are using 2 breakout cables (one on the codec, one on the camera) for the proprietary HDMI/control plug (instead of using the supplied cable). The breakout cables are CAB-PHD4XS2-SPLIT=. Getting an image over HDMI through the breakout is working. Using the remote to dial a number, access menus etc is not working. There does not seem to be any communication over the UTP cable that carries the IR requests back to the codec. We are using a power supply to power the camera, but when this is removed the camera still seems to be powered via POE.
Do we need a custom pin UTP cable between the breakout devices? We have used a standard CAT6e cable and a standard cross-over cable. We have also tried swapping pins 3 and 7, and pins 3 and 6, as we have seen to be possible solutions posted on the web.
