Hi, so without trying to get super technical, the GO is more of a wireless controller communication, to make it a true wireless DMX system it would also send wireless DMX over the network to fixtures that have the same protocol of wireless DMX receivers, it does not, it only wirelessly communicates from GO to iPad, that is not DMX, the GO hardware is sending DMX out of the DMX output 1, that is hardwired.
One thing you could do to test, is on a Mac or Windows computer, download Hardware manager, and plug the GOs usb into the computer, launch hardware manager and use the DMX tester section of the program to test the DMX going out of DMX output 1. See pic attached to this post.
