In addition to what they said above....
If you use the DishPro Plus Twin LNBF:
- It must be connected to Ports 1 and 2, which will default to Port 1 = 119 & Port 2 = 110.
- Once you connect the DPP Twin to a switch, the input port will be disabled, so you will have to connect your wing dish to the DPP44 Port 3.
It sounds like you probably don't have a 4th satellite position, but are only using the DPP44 so that you can run single cables to your dual tuner receivers; and you have more than 4 receivers, so you are adding the DP34 to the side of the DPP44.
If any of your single tuner receivers are legacy receivers, then you will either have to directly connect those to a DPP44 switch, or to a DP34 switch using a "DP Adapter".
