We are attempting to mount the Honeywell sensors in the gearboxes today. If it is successful, I will post photos.
As for the the software, we used INT2 and INT3 on digital inputs 1 and 2 to count the GTSs.
I posted examples of this code in the other
Honeywell thread. Be sure you fix the "INT3P" problem in the MPLAB *.h file as described in other Delphi threads or you can't compile.
Good Luck!
