Leviton DMX Data Distribution Merger

A DMX merger is used when multiple control inputs must communicate to the same device. A DMX merger helps to completely rid a system of complex, error-prone, multi-location DMX input wiring schemes. This merger combines all (8) inputs, using a highest level takes precedence (HTP) philosophy into a single 512 channel DMX output. All inputs are optically isolated from each other to ensure the protection of sensitive equipment.
