SIX Pack interaction

Guys,

Im a bit confused so would appreciate clarification.

I have always run the six pack directly via PM systems to a phidget 64 led card.

I also have the CP Flight MIP board and this also has connections for the Six pack

and lately I see that Thomas Richter has launched a B737 software which i dont have (yet) (i have the cockpit system software, but not the display and NG packages ) which again has a separate six pack functionality..

So which is the best one to use and above all WHY??

Tks
Peter
