I did the same for one of the plug ins in FL for my Oxygen 8. I turned each knob and got the numbers for them. Now I forgot the plugin i was messin with...damn. I wrote the numbers down though :p
I gotcha...
Get a 4-port hub, connect both RJ-45 cables to the hub (install whatever software that comes with the hub) go to Network Neighborhood find other PC, if it doesn't show up try refreshing Network Neighborhood. Any more questions...pm me.
