installed happ trackball wrong way .....help

<< < (2/2)

PL1:
Glad to hear it is working now.   ;D

To clarify for anyone reading this thread later, your description sounded like one axis was ok and the other was backward.

One axis backward (i.e. pushing the trackball left makes it go right)= swap the data lines for that axis.

Swapped axes (i.e. pushing the trackball left makes it go up) = swap data lines from one axis to the other. (or swap connectors from one optical board to the other)

The green wire (top of pic below) should be connected to frame ground to bleed off any static electricity the trackball generates.
