Doug Fleenor Design 221E-WALL Two Input Enhanced Wall Mount

Doug Fleenor Design 221E-WALL Two Input Enhanced Wall Mount

These DMX combine units are designed for use in permanent installations and can accept as many as six DMX512 inputs. They can be mounted directly on a wall or can be mounted in a 12"x12"x4" junction box if conduit entries are required. DMX connections are made with pluggable terminal blocks and the power connection can be plugged into a wall outlet or into a terminal strip. All DMX512 inputs are optically isolated and terminated. These combiners can also be used to convert or accept Colortran's CMX protocol.
