I am only using one port on the MAC. I have it connected directly to the Acclaim Artnet box. The Acclaim Artnet box is the Acclaim X-Net8 if that helps. So nothing else on the network. On the artnet screen I can see it sending data out. On the screen that shows all the DMX values being sent out over artnet, I cannot seem to get that screen to show anything other then zeros, even when it is working. It says the IP address is 0.0.0.0. I don't know how to change that. I will try and post some screen shots when I can. I am going out of town for a festival this week ( not something the Catalyst is on ) and so it may be after I get back from that.

Thanks for the help.
