INPUT 1 – 16 (Levels 1 – 4)

There are four levels of 16 inputs, each input has two RCA jacks connected in

parallel (one for video input, one for termination or loop-through), which is used to

connect independent video sources to the CNX-PVID8x4. Each connector is

supplied with RCA terminators (75 ohm). The terminators should remain attached

unless the INPUT connectors of multiple units are connected (loop-through). Refer

to "Signal Distribution to More than Eight Rooms" on page 19 for a description and

illustration about loop-through. The last unit in the loop must have terminators

installed.

All video inputs have a video sensor so that the power status of all components can

be reported. Only inputs with sync can be reliably detected (composite or

luminance).

OUTPUT (RCA Connectors)

There are four levels of eight RCA jacks (32 total) for single ended (local mode)

video.

NOTE: The information on the OUTPUT RCA connectors and OUTPUT RJ-45

connectors are identical; they are not independently controllable.

OUTPUT (RJ-45 Connectors)

There are eight RJ-45 connectors for differential digital audio/video (CAT5 mode).

The outputs are grouped into four pairs and correspond to the input levels as shown

in the table after this paragraph. Use a standard CAT5 cable.
