Had an interesting session with Danbar yesterday trying to get his dd-100 controller working. These little controllers except DMX input and output 2801 for these 12v pixel Modules. After we sorted out a issue with the controller being labeled wrong for the clock and data we had a problem of not being able to use channel 1 when being controlled by an open DMX dongle. The behavior was: The modules are GRB ch1 = nothing ch2 = Green ch3 = RED ch4 = Blue everything was off by one channel. We found this to be very strange as it worked perfectly when using a DR-4 to send the DMX to it. Phone a friend Time (thanks David_AVD) The possible cause of the problem was the controller was possibly missing seeing the first packet of data sent to it due to the open DMX dongle. or something like that. Turns out it mad sence in the end. Loaded up LSP started the controller from ch2, reconfigured the string in LSP to be RGB and fired it up. Problem solved.
