I am having problems slaving my Viewsat 2000 to my 4DTV. I am using 2 splitters and a Diseqc Switch. My splitters pass DC and I believe that is part of the problem. I need to know exactly how to wire the C Band and Ku lnbs to the receivers. Which uses DC and which doesn't and how do I set up my FTA receiver? Does it use lnb voltage or is that supplied by the 4DTV? Thanks in advance.
