If you add and remove satellites from the Dish receiver, you are going to have to run check switch each time you change which satellites are available. I also believe that if you have the same satellites, but move them to a different Input Port, you also need to do a check switch.
If you have all DP LNBF, feed them all into your DP34 or DPP44, and then feed the DP/DPP Switch to your Dish receiver; do not route the signal through the motor and/or another receiver that has pass-through.
Now if one of those 3 or 4 orbital locations are on a larger single orbital location dish that gets better reception, and you have the need to move it between orbital slots, and you do not mind running check switch each time, then you may want to run a second cable between the motor and the pansat 2700 just to control the motor to move that dish back and fourth.
However, I thought you had a large dish farm on your roof; if so, it would be better if you could just designate various dishes on a permanent basis and get the correct switch(es).
EDIT: I guess in theory, you could put 119, 110, 61.5, and 129 into a DPP44 and then run it to your receiver, do a check switch and the receiver will recognize all 4. You could then replace either 61.5 or 129 with a different DP LNBF and dish, but each would have to be on the DPP44, and on the same port originally scanned. But if at anytime the receiver does not find a satellite when channel surfing, or maybe during a reboot, you will get a lot of errors.
