Wiring Ultimarc Trackball for Mouse left Button

[johnnyskullhead]

Hi Hoping someone can help

Got Ultimarc Trackball works fine, but want to use as mouse in Cabinet, so i dont need a seperate mouse.

Currently using trackball to USB straight to PC and Ipac 2 for Joysticks and Buttons

Anyone suggest best way to wire up spare button to use as left mouse button

 

Many Thanks

Do you not have any unused pins left on your iPac?

If you do, just wire the button to it and in the WiniPac software set that pin to Left Mouse Button. (I have my cabinets mouse buttons set to iPac pins 1B and 2B)
