bb, we may be able to help but need a bit more information?? Here are the basics though.
First, connect your dish coax to the Sat connection in the docking center. There may be two connectors and you'll have to determine which one goes to the entertainment center.
Next, connect a coax between your DTV receiver "in" and the wall plate for the satellite coax from the docking center.
Next, connect a coax between the DTV receiver and your TV input. You have to determine which input to use on the TV. Analog HD, HDMI, Phono plugs or regular RG59 coax.
Set the input on your TV using your remote.
Get your receiver fired up and find your coordinates for your location.
Aim your dish and away you go. Simple as that, right???
