In another thread, one of the members described an unusual configuration he wanted.
I won't say it's exactly like yours, but let's take
his diagram and see if we can fit it to your problem ...
We need to print out the picture and mark it up.
See if the following steps would work for you:
- your Invacom QPH-031 connects to the upper left 4x4 switch; both C to the left; both L to the right half of the switch
- get a
dual output C-band LNBf * and connect its two outputs to the switch on the right (which is currently shown as a 2x4, but could be replaced with another 4x4)
- three 2x1 diseqc switches are shown at the bottom of the drawing; it's probably easier to use 4x1 switches as they are more common
- should be easy to see by inspection, where the fourth diseqc switch and receiver would be wired in
- between the left-most receiver and diseqc switch, locate your SG-2100 motor
- I would use two self-powered 4x4 switches, if I go this way.
Code:

Again, this is just a suggestion and a starting point for discussion.
Feel free to take it in any direction.
