Pin Layout Dual Strike

[Francis Sutherland]

Hi,

I have been looking at using the Dual Strike Encoder PCB (http://arcadeforge.net/GamePad-Key-Encoder/Dual-Strike/Dual-Strike::17.html) to make my own "Non Stick Arcade Box" (Hitbox for all intents and purposes)

I see the Pin layout in the manual, but it doesn't say how yours is designed to be connected, so you use a common live and connect the earth to the relevent point for said buttons, or do you connect the relevent buttons and then use a common ground?

Or does the board have two connectors for each button, IE Pin 4 is Up, will there be two connections marked as 4 to be used for that button?

Regards
Francis
