Hi Gert noticing real bad comunication with RDM ! Example: en4 node connected to PC via Art-net and fixture plugged into universe 1,i was able to see all Infos, but not able to change DMX addr ore mode of fixtures.
2 try, plugged DMX directly in an NX 2 same issue until I restarted the fixture and the Nx2 ,then I was able to change! Why? Fixture was a Sagitter W8 wash.
