I had a tech come out today and he rewired the dish and my swm coming into my apartment. He has one wire from the swm-16 going to my sisters apartment, and the other swm output going into my apartment. That wire is going into the 8 way splitter. The power inverter is going into 1 of the ports on the splitter. Now my question is that I read that the open ports on the swm-16 should be terminated, but the tech left the middle port for power open. Do I leave it open or put a cap on it? Dont know if i made my question clear.
