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 $$$$.
