My setup is 2 satellite dishes (500 & 300) going to 14 311 receivers. My question is what kind of switches do I need to buy to make this setup work. I have seen 12 receivers hooked up using 3 DP-34 switches which I can see possible on a graphic layout on a DP-34 which shows the first switch allowing you to connect to 2 extra switches. Each switch allows you to go to 4 receivers. Do I need to buy 4 DP-34's, will it allow me to add on? Also, is there any other kind of installation I need to do/buy or just hook everything up and do the check switch test?
