  • NRI coin mech and LAI credit board

    just brought a nri coin mech for my neo geo 4 slot, when i hooked it up it will take 20c, $1, $2 but will only register 20c coins.
    could some one tell me the pinout for the LAI credit board so i can check my setup, and what the dip switch in the NRI coin mech is set to
    i have been on the sunrise credit board web site but dont know which credit board to look for?

      The factory settings for $1 per play are as follows 1;ON 2;ON 3;OFF 4;ON. For 60c per play 1;ON 2;ON 3;ON 4;OFF.

      Also a bit of information that might be helpful, i'm reading this off the paperwork iv'e got.
      Should the credit pcb become faulty the LED will flash on and off. A short flash when power is applied is normal,
      with the LED being off when operating correctly.

      Hope it helps.

        the dip switch on the credit board has 8 settings and the one inside the nri coin mech has 6, what settings are you referring to that only has 4 settings?

            I went ahead and figured out the basic DIP settings for the LAI credit board + NRI coin mech. Tested on my 4-Slot Neo Geo Cabinet:

            DIP 2 ON: $1 (6 Credits), $2 (12 Credits), 20c (1 Credit)
            ALL DIPS OFF: $1 (5 Credits), $2 (10 Credits), 20c (1 Credit)
            DIP 2+3 ON: $1 (4 Credits), $2 (8 Credits)
            DIP 1+2 ON: $1 (3 Credits), $2 (6 Credits)
            DIP 2+4 ON: $1 (2 Credits), $2 (4 Credits)
            DIP 1+2+4 ON: $1 (1 Credit), $2 (2 Credits)

            You can pay with 20c pieces for any amount, but the credits increase incrementally against the value of $1 dollar to credit division.

            Hope this helps someone down the line...
