I just had my vip722 upgraded to hopper 3 and joey 3.0 and was wondering about the dish cables going into node. I only have 1 of the cables from dish connected to the node and other was left disconnected hanging there. Is there a way that only one cable from dish to node works? If left that way any thing I would be missing? From all diagrams I see it uses 2 cables so I am concerned but it does seem to be working fine. Any thoughts?
