I have (2) ADJ DP-20A dimmers. I'm looking to control them. I'm thinking about buying the dmx to 0-10v decoder below and using a cheap dmx controller. According to the pinouts, I'm thinking about wiring channels 1-4 from one pack and 1-4 from a 2nd pack to make 1-8 on the converter. Then I wire both to the signal ground. It appears that the dimmers have an option to communicate to each other through the center pin with 20v. But if I don't wire the packs to each other it should work no?
