When you say "wire up directly" do you mean you are soldering wires directly from the dc30 to the e682? I ran those dc30 controllers connected to pixel outputs, which is what I think you mean, but most of the controllers now have dmx output or outputs that you can connect several different types of ac 110v controllers... I even have my old 2006 LOR controllers connected that way. I have no idea if the e682 has that capability or not, I have an e6804 that can do it and then the j1sys, advatek controllers and falcon controller can all do it.
