Looks good, Mike.
I had a nice long post on setting up Ethernet, but since Microsoft is the most unstable software available, I lost it... I'll recap.
On home computer, go to Command prompt (Start-->Accessories-->Command Prompt or Start-->Run-->cmd). Type in ipconfig/all and hit enter.
Write down the IP, subnet, gateway, and DNS info.
Plug that info into the controller's Net setup. Everything should match between the two devices except the IP. The controller needs a unique address. If the main system is 192.168.1.50 and no other system on the home network has 192.168.1.60, you could use that (or anything similar, etc.). Once all of the info is there, and the connections are made (Ethernet (I'm assuming?) from controller to router/hub/switch at home network), you should be able to access the controller via the IP. Open a browser and type in the IP and it should take you to the site.
You can ping the controller to see if it responds. That'll let you know if you have a connection. From command prompt, type in ping {IP address-whatever you decide to go with for the controller) and hit enter. It'll send four messages and look for a a reply.
