IM trying to hook my 2 pedals to my A-pac. Double checked the wiring everything seems good. I have 3 wires from potetionometer. When holding the potetionometer upright i have the first tab as the ground and the other 2 notsure but all 3 is hooked tothe a-pac. Also in MAME the settings say keyboard next to the pedal device in  the MAME settings not sure whats thats suppose to say changing it to mouse didnt work! Any ideas

PL1:



From Ultimarc's A-Pac page.

Details and FAQ on link. Hope this helps.

Edit: If you wire it like the diagram above and it's working backward, swap wires 1 and 3. (power and ground, I believe) This should fix it without editing every game's configuration, since it will swap one end of the whole resistor for the other.

Nah did that still not working!

PL1:

When it's wired like the diagram, does anything register on the calibration/test page when you move the pedal? Is the indicator centered or in a corner?


To verify the potentiometer is working.

Power off and disconnect from the A-Pac
Hook a multimeter to 1 and 3.
Set to Ohms.
Watch meter as you press the pedal. Does the reading increase/decrease?
The reading should stay pretty steady -- if not, find the two terminals that maintain a steady resistance reading and call them 1 and 3. Verify that readings vary when connected to 1 and 2 or 2 and 3 and the pedal is pressed.

I've never used one, but it's my understanding that the A-Pac shows up as two gamepads. 
Check to see that it's showing up in windows under game controllers before messing with MAME.
You should be able to calibrate the axis and see them move in windows.
