    Help, I hooked up my new 921 to the existing LMB (it looks like an oblong rectangular white cover over the electronics, there were two outputs labeled 110 and 119 ) twin?? dual?? . I added another coaxial from the 110 to the #2 sat input. Now, I'm getting an error message. What IS MATRICES? What do I need to do?
    Does anyone have picture of the correct equipment?
    thanks :confused: :confused:

    There's plenty of pictures out there. You probably have a Twin - 2 outputs, one very wide 'eye'.

    You ever hear of "Check Switch"? It's an important concept. Even though you don't have an external switch, it needs to be done. It builds the switch matrix.

    Oh - when you reference an error message, it's considered good form to tell us what it is. (hint, hint).

    Moving to Dish DVR forum. This is a setup question, not a software question.

    If you have a Twin LNB, then you need to connect 2 coax lines to the LNB, and connect the other ends to the 2 satellite connectors of the 921. Then you need to run a check switch. Go to the Menu, System Setup, Point Dish, Run Check Switch. Both tuners must be looking at the same satellites, so if that is not your setup, then you we need to know more about your existing equipment.

    Thanks for the input, tonight after work I'll get the exact error message. Part of the problem was a defective coax cable (that the check-switch tip revealed).
