I have a legacy 4 wire dish with a SWM-8 in the attic. I currently have an HR24. 4 wires from the dish go into the SWM-8 and then the output goes directly into the HR24. I have the power inserter going into the SWM-8 as well. On the HR54, the wiring diagrams show that I need to use the splitter to split out the power pass? I don't use the splitter on the HR24 now. I am 100% sure on that since I hooked it up. Is the no power pass splitter just something for the HR54?
