Typical CAN voltage should be 2.5v. The round plugs don't do anything except for the 9 pin that connects to your ATU, in my experience anyway.
Do you still have the brown box, and if so, does the 3000 still work with it?
If the brown box doesn't work, next thing to check would be the receiver itself. I've had the harness between the combine and the receiver go bad before. Simple as switching receivers if you have one or placing on another machine.
