I have an SWM8 switch. It works great for my HR-2* receivers, and the Legacy ports have been working great for my older receivers. I had an R-15 running on one of the LEGACY ports, and now I'm trying to replace that unit with an H21-100. I've hooked it up but it is not getting a satellite signal (771 error). Upon initial setup, I selected "SWM" as the type of switch and I did not have the BBC connected. It completed the setup, but in the sat test, it was not getting a signal from 2 of the positions (the HD ones, I am assuming). I then tried it with setting the switch type just to "Multiswitch". Still had no BBC connected. Still had the same issues. I then tried it with the BBC, and no luck. So now I'm stuck with a 771 and no way to get back to the setup screens. So, is it possible to run an H-21 off of a LEGACY port from an SWM8? If so, do I need the BBC? If so, in the setup, do I specify SWM or Multiswitch? Or can you not run SWM compatible receivers through the Legacy ports? Thanks in advance.
