CRemove system power before making all connections.

Video connections

NThe matrix switcher does not alter the video signal in any way. The signal output by the switcher is in the same format as the input.

NThe MVX 128 A can also switch RGBS, RGsB, RsGsBs, component video, S- video, or composite video by using the appropriate adapters.

a RGB video inputs — Connect the analog computer-video sources to these 15-pin HD female connectors.

NMost laptop or notebook computers have an external video port, but they require special commands to output the video to that connector. Also, a laptop’s screen shuts off once that port is activated. See the computer’s user’s guide for details, or contact Extron for a list of common laptop keyboard commands.

b RGB video outputs — Connect RGBHV video displays to these 15-pin HD female connectors for each output.
