I have just completed installing a new light rig with 9 dp-dmx-20L and 2 DP-415s. The control console is a Fat Frog board from Zero88. I just finished addressing everything, plugging it into the board and setting the DMX channels in the board. Unfortunately, not a single light comes on. Are these dimmers compatable with a Fat Frog board? Also, are the DP-415s compatible in line with the DP-DMX-20Ls?
