I don't have a fpp in the setup.
I have set the jumpers to DMX, I set the starting channel at 161. I assume that setting the dip switches in DMX mode is different than LOR mode since in LOR this would be the controller ID. With this setup, when I got into xlights and try to do a test and turn on any channels from 161 and up, no lights. I created a model, basically a matrix with 24 strings of 1 node each, and had it start at Universe 50 channel 161. 50 is where all my LOR stuff is.
