Yes, the +5V/square wave/ground connections are the polarizer (servo) connections.
And yes, you do need something like a relay to hook both receivers up at the same
time. Someone with more electrical experience could probably offer various alternatives.
As far as programming, it'll probably be more complicated than that, but I really
don't know, as I haven't fiddled with a recent Pansat receiver. I've used an older
one that required entering all the info manually with the remote. Big pain.
