I suggest you go to "Edit post" and change the name of the thread to something like "What is correct hookup of this Dish Receiver" or "...of Dish 310 receiver?"
I will bet that a lot of people who have looked at this are DirecTV experts. If you put the Dish brand in the name of the thread, it will attract people who can answer you.
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
