Brief Description

The VC Node Mux is an electrically isolated 16:1 multiplexer. The 16 inputs can be

assigned to one of the two outputs through jumpers. Use of EIA-422 interfaces allows

distances of up to 1,000 metres to be linked. The system is controlled through a data

vector that limits the maximum number to eight VC Node Mux devices in a chain

(eight VC Node Mux devices



128 channels). Chaining can be made through a

short flat ribbon cable (lateral connectors).
