I don't have it in front of my right now, but on the left of the screen somewhere there should be a selection that will put in 32 universes of 512 channels. Then all you have to set is that you want multicast.
After that you will go to the Test at the top of the screen, select the channels that you want to test, check the output to lights box. On the right there is another box that you can select chase, background ect. You can select the rgb tab if you want to play with colors, but if you just want to turn them on select background and move the slider up and lights should come on. Hope this helps.
