I got my SWM-8, Power Inserter, Splitter in the mail today. I installed everything per the chart in the SWM-8 Wiring : Basic 4 DVR guide on solidsignal. The only difference is I have only 2 HR21s and 1 legacy rcvr (which I didn't bother with yet), I have the same splitter as in that diagram as well. I had my HR21s powered off during the install, head back in power them up. Do the manul satellite setup, set it to the Slimline 5 dish and SWM. Wait, wait, wait....wait some more only for it to come up and say somehing like "Tuner 1 & 2 no signal 771". This happens on both my HR21s. Did I do something wrong? Are my HR21s jacked up? Do I just need to drink more and wait for it to magically work?
