Hi, I am having problems opening the Iris/shutter on the FutureLight MH860 using my school's Strand 300 board. Our hook up is: Strand 300 board > Network switch via CAT 5 cable > SN102 Network Node on our second fly-bar > Moving Head 1 via DMX > Moving Head 2. I've patched the moving head 1 to DMX 200 and the other to DMX 220. Although I was able to change colors, gobo, pan it Horizontally and Vertically using the board. I tested the Demo modes 1 & 2 on the Moving head and it works the shutter was able to open and run.
