Q: Is possible to introduce more than one DMX controller on a single DMX circuit? For example: If I were to run a single DMX RGBW decoder and connect 2 x wall-mounted DMX touch controls operating the same channel.
A: No, this cannot be achieved in the way described. In order to do this, you would require 1 DMX master and 1 wall mount to a single zone, so effectively doubling up. You can also have one DMX Wall Panel and multiple DMX Decoders.
To successfully manage this alternatively, you can forgo DMX entirely and pick up the 4-Zone RGBW Wireless Wall Mount and pair it to a RGBW Controller. Up to seven can be paired to this controller. Or you can use multiple controllers.
