Trackball (via MiniPAC) - Y axis reversed??

Pages: << < (2/3) > >>

stuzza:

I just reversed the TY1 and TY2 connectors (Pin 35 and 36) going into the minipac and it worked like a treat!!  Up is now up and vice versa!  Yay  ;D

Thanks for all the help guys!

One more quick question, do I need to connect the Green (ground??) wire coming out of the Happ trackball to something?  Or is it safe to leave it unattached?


Lomar:

I'm dying here!

I've been looking all over for how to get this dern trackball to work.

I have the Happ Trackball with the Mini-Pac and I have "no clue" how to connect it.  I have the happ wiring harness and I plugged in the only two wires that seem to fit into the trackball ... nothing.  I swap the wires ... nothing.

WHAT am I missing?!?  How come I can't find anything about this?!

Help!!!

Green wire is a chassis ground designed to keep static from the spinning ball from affecting the electronic circuits.

I have seen posts saying you could leave it unconnected.

If you do connect it, you want to connect it to earth ground (i.e., the metal case of the computer or better yet, the lower prong of the AC line into the Power Supply or the ground cable at the wall socket, not the GND terminal on the encoder).

Although shouldn't the GND terminal on the encoder feed back through the PS, which then goes to the lower wire GND so it does the same thing either way???

According to Ultimarc's diagram, pins 35 & 36 are the two that need to be swapped.

Before you do that, is the trackball's Y axis reversed in Windows?
