Ethernet connection diagram?

[DaleB]

Hi. I had my D-Command Main Unit and Fader Units hooked up for the past four years... to an older (2010) Mac Pro tower. I disconnected the ethernet cables to do some minor trouble shooting. I guess I should have labeled my wires... because I can't get Pro Tools to sense BOTH units at the same time. It's always one or the other. Does anyone have a fool proof way of describing the best way to hook up these units? A cabling diagram? I've been using a ethernet hub, to allow me to have a wired internet connection as well. I can get the internet and the main unit working... or I can get the fader unit and the internet to work... but I can't seem to get BOTH units working. If I have the internet and the main unit on the hub (using Ethernet port 1), I figured I could plug the fader unit into Ethernet port 2. But when I let Pro Tools scan a port, it then forgets the other port exists. And vice versa. Was I supposed to plug BOTH units into the hub? or just one? Guesses anyone? Or wiring diagrams?
