If I read your post right, you're using the 1000.2 to pick up the 61.5 satellite, correct?
Make sure that you have the cable connected to the right "out" port on the LNB (if it's in the wrong port, it will not show when using the DPP44). If you bypass the switch, and run a cable straight to the receiver, the internal switch on the DPP LNB is probably kicking back on, which is why it can show up when you run a cable directly to the receiver, but not when using the external switch.
"Conn" means something is connected, but it's not getting any signal from that LNB
