To use a DMX controller reasonably requires you a detailed instruction manual, this is not the case here. More than can be read on the front panel as the label is not found in the manual, you have all more or less find out for yourself. Unfortunately, this device has also no way to assign DMX channels. Also disturbing the garish blue LEDs and a knob for sensitivity was also saved, it stands out only the axis of the corresponding potentiometers from the front panel. All in all from me neither a recommendation, my unit comes back.
