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.
