The connectors

The figure below shows the connectors on the rear of the GTm 5250 codec.



The table below describes the connectors:

Using the correct HDMI and DVI cables

When connecting HDMI or DVI cables to the camera inputs, the PC input, and the telepresence screen display outputs, ensure you use the correct gauge of HDMI/DVI cable. For short cable lengths of up to 5m (17 feet), use 28AWG or thicker core. For longer lengths, use 24AWG or thicker. StarLeaf does not support the use of HDMI or DVI cables of longer than 15m (49 feet) with the codec.

Extending the camera cables

StarLeaf room systems that use a PTZ camera are provided with camera connection cables of 5m in length. If you need to install the camera further than 5m from the room system, you must extend those cables.

You can extend those cables using a third-party product called an extender. This product effectively carries the media and camera-control signals across a cat 6 Ethernet cable.

StarLeaf has partnered with Sound Control Technologies to provide this solution which is available at http://www.soundcontrol.net/solutions/#
