SatPC32 and Nova both support Flip mode directly. Just follow the
instructions within the programs on how to do the set up.

I believe the G5400 is a 360 degree rotor control. If you are wanting
to go from West through North to East, you will hit the stop.
Two options come to mind. Put the stop at South, but this gives the
same problem going from West to East though South. The second option is
a program like FLIPANTS that turns the antenna on it's back and turns
the Az control plus/minus 180 so that the stop is not a problem.
Decide if the "through North" or "through South" will become a problem
and make a choice, then use the software to overcome it.
Flipants is a old DOS program, but I think you can find an equivalent
available. Click below to go to download Flipants.
Good luck and I hope this helps solve some obstacles.
ps: The G5500 rotator has a 450 degree travel and helps diminish this
problem, but it will cost more $$$$.
