SX-20 Camera Communication Over UTP

Unanswered Question

User Badges:

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.

Questions about the SX20 codecs are probably better asked in the TelePresence section of the forums, so you may wish to move your discussion to there.

In any case, the maximum supported distance for the Visca Control (serial cable) is 20m / 65.6 ft, so you shouldn't have issues extending it to only 3m.

It is recommended that the camera is powered separately when using such an extension to the cable, and that the +12V pin on the Visca Control cable is not connected, apart from that, a straight through cable is required.
