I was looking through some floor pockets at church last week and found a DMX Node is one of them. It was unplugged but the cat5 cables were lying there, so I plugged it in and it came on and said Universe 3 on it. I finally figured out where that Universe was! I knew we had it, but no one could tell me where it was and even if I had found it, it wouldn't work due to excessive signal loss. Well on the screen, of the node, I believe it said Universe unavailable. I decided to plug a fixture in anyway, and it did in fact work. What exactly is the function of the node, why not just connect directly to the board? I have a read few pages on it, but doesn't really make a whole lot of sense. Why would it say U3 unavailable when it did in fact work. We run an ION board. The node has 2 outputs and was about the size of a double gang elec outlet, not the big rack mount units.
