VIDEO SOURCES

The CM6800E offers 48 full-function video inputs which support Coaxitron PTZ control and video loss detection. Forty video inputs, labeled 1 through 40, can be used for looping video connections with terminating and unterminating switches on the back panel. The eight alternate source inputs, labeled 41 through 48, are terminated inputs. They do not have loop-through connectors or selectable termination switches, but otherwise they offer the same functionality as video inputs 1 through 40.

All 48 video inputs also provide the ability to view and interface with other devices, such as Genex multiplexers. If control of the device connected to the video input is required, connect a data cable between the multiplexer and the CM6800E. Refer to the Connecting Genex Multiplexers section for instructions on connecting and controlling video from a multiplexer.

Figure 6. CM6800E Video Inputs

1.Connect video cables at the appropriate video input BNC receptacles on the back of the CM6800E. For best results, use crimp-on BNCs only. Do not use screw-on BNCs; these typically do not provide adequate ground and signal connections.

Refer to Table A for video coaxial wiring requirements.
