I'm trying to add another LNB to my dish to get additional channels. I have cable going from each LNB to a DPP33, ports 1 and 2, I have a single cable out of the DPP33, going into a second DPP33 where I'm attempting to split the signal in order to feed my Two VIP222 receivers. At the receivers I have a Triplexor 1 cable in 2 out going to Sat 1 input and Sat 2 input. I most be doing something wrong because when I go to check switch on the receiver it is only picking up the LNB going port 1 on the DPP33. Help!
