To clarify, I have 4 MR16s, and so far I have only been able to change 1 of them. 2 of them I bought from another member here and they were set to different addresses, so they have been changed before, but I could only get 1 of them to change for me. And my other 2 are new and I cannot get either one of them to change for me.
The dongle is only DMX, not pixelnet. And the steps I took were: 1) Open RJ's Address Utillity 2) Turn controller off and move the jumper to program mode 3) Select the channel and click on "Program" 4) Turn power onto the controller again and wait about 5 seconds 5) Turn the power off to the controller and move the jumper back to operation mode 6) Click stop in the address utility.
