I just moved into a new house. My old house had a Zinwell 4x8 multiswitch with a 21-35v power inserter that came with the Multiswitch. I have two receivers, an HR24-100 and an HR24-200. Both worked perfectly at the old house. I had two cables running from the multiswitch to each receiver and two B-Band converters for each receiver. The new house came already wired with a dish with an SWM LNB and an 8 port SWM splitter. Unfortunately, the previous owner took the power inserter, so I installed the inserter from my multiswitch on the appropriate port of the SWM multiswitch. I connected a single cable to SMW-2 port on each receiver and I am NOT using the B-Band converters. I went through the sat set-up on the HR24-200 and everything works great - absolutely no issues. HOWEVER, the HR24-100 is NOT working. It is giving me various error messages - sometimes it says the SWM registration has failed, sometimes it tells me to disconnect the B-Band converter (which is not connected!) The "Recheck SWM" is grayed-out and I can't select it, however it seems to have auto-detected the dish model and the SWM. At one point I actually had a good signal and picture, then it gave me an SWM registration error and told me I had to restart the receiver. My first thought was (of course) the non-D* power inserter - but if that was the problem, why would one receiver work and one not work?? Could the SWM portion of the HR24-100 be bad and it wasn't problem on my old multiswitch? This isn't my first rodeo - I've been on D* for 15+ years, but I'm baffled.
