Ground wire for Button 2 on light gun

[tylerwerrin]

Hi guys,

This is probably a dumb question, but I just want to make sure that I will be OK in doing this:

I bought 2 AimTrak modules and put them in two Unico clacker guns. The guns are great, but only have a trigger (no alt button like a GunCon, or GunZ lightgun). In the effort of simplicity, I am just going to wire the "Button 2" wire from the Aimtrak module to a foot pedal for games which need a second button to reload/bomb/duck (like T2, CarnEvil, Time Crisis, etc).

My question is, since the metal tubing I have which connects the Gun to my cab only is too narrow to fish down 2 wires (one from the AimTrak module, and one for the ground). In the AimTrak documentation, it says that the Button 2 wire must be wired to the Aimtrak ground pin (like i did for the trigger function). However, can I just ground the wire to the foot pedal itself? Or some other ground? Do I have to use the ground pin supplied on the AimTrak module?

Thanks!

Tyler

I am not 100% sure but I don't think it will work that way,I think the button will have to have the ground wire run back and connect to the aimtrak common ground.You could use a 3.5mm female jack on the bottom of the gun handle,and pedal,then use a 3.5mm audio wire that connects from the gun, to the pedal when you need it.

It should work, just connect the other switch contact to the PC casing. There would be a ground path to the gun via the USB cable.
