The hybrid lnb emulates multiple different lnbs. The Hopper 3 utilizes "DPZ", which is how it gets it's 16 tuners. You can run up to 8 or even 16 Wallys (in single tuner mode) off of 1 DPH lnb and a DPH42 power supply. Generally that is only done in commercial installations. It emulates the solo node for Hopper 1 & 2 (3 tuners). For Wallys, 211s, 722s, Hopper duos etc (anything with 2 or less tuners) it emulates the DPP lnb.
The Hopper 3 is the only receiver that should turn off port 2 on the lnb, it needs to to run 16 tuners. There is a software glitch I have seen where a Wally hooked to port one will turn off port 2, it should not do that. If the Wally turns off port 2, what is its point in the 1st place?
