happ trackball to ipac
ronfedele:
ok start with the concept that i am a total idiot and need this answer in small clear words
started building a control panel 10 years ago life got in the way just getting back to it
just bought an ipac 2 my board has a happ trackball no idea of model it has 10 wires coming off it 2 bundles of 4 and 2 separate heavier gauge green wires what is my pinout to molex connector for ipac and do i need to run separate power i have looked everywhere and am just getting more confused
help please an idiot in his quest
ed12:
the 2 heavy green wires are earth ground
the other wires are dc+ red
dc - black
the other 4 wires are your x and y axis outputs
on my happ track ball new style (open frame) using the red sensor boards
as follows
purple @ blue =1 axis
green @ yellow = 1 axis

Welcome aboard, Ronfedele. ;D

The two heavier gauge wires are frame ground.
- They bleed off the static charge generated by the rolling trackball.
- Connect them to ground like the case of the power supply.
You don't need a separate power connection.
The two bundles of 4 wires contain:
- 5v (red)
- Ground (black)
- Two data lines X1/X2 or Y1/Y2 (purple/blue or yellow/green)
The 8 wires go to the 0.1" (Dupont) pins labeled "trackball". (left center)
If your trackball has an arcade-style Molex (white 6-pin below) harness instead of one with 0.1" (Dupont) connectors, GGG carries a Trackball Cable for Opti-Wiz™ "No-Solder" that replaces the molex harness.
The replacement cable plugs into the optical "red boards" on the trackball and has Dupont pins on the other end.

The image above shows an Opti-Wiz, but the trackball cable will work the same way for your I-Pac2 -- just lift the tiny lever and pull the female Dupont ground pin out of the 5v/ground Dupont housing since 5v and ground aren't on adjacent pins.
Troubleshooting:
If an axis is reversed, swap the data lines for that axis.
i.e. If moving the trackball right moves the mouse cursor left, swap the X-axis data lines (purple and blue wires)

Can the Happ trackball used as a mouse with the ipac2?

Yes, a Happ arcade-style trackball (the kind with a 6-pin Molex, not the kind with the Happ PS/2 or USB encoder :puke ) + I-Pac works exactly like a mouse.
The I-Pac firmware shows up as a USB HID Mouse device so it will work with any system that has a generic USB mouse driver.
Of course, this assumes that you have a 2015 or newer I-Pac with the trackball optical input pins. (pictured above)
