Basically, I have this:
I have a Dish 1000 for 119,110,129 and a Dish 500 pointing at 61.5 and a DP44 switch. On this switch, I have a 622 using 1 port, a 211, and two 311's using the other ports.
On the back of the house I have legacy Dish 500 quad and Dish 300 dual, with SW21 switches that feed another 622, dual cables.
I needed to add 1 more 211, that cable terminates by the other DP44 switch, so I added a DP44 for that one receiver. If I can get another cable to the Dual DP 44's from the Downstairs 622, I would like to do away with the leagcy dishes all together, but not sure that's possible.
I did get the DP44's working together now, all seems well.
