      I have an MEI Cashflow 340 coin acceptor and was wondering if anyone would have an idea on how to connect it to a pi 4?

      Getting it to work in game with GPIOnext isn't an issue, it's understanding the output voltages to physicslly connect everything before I blow something up.

      I have the manual which explains the outputs but it all seems gibberish to me

      Outputs Player 1 output: (PLAYER1HI, PLAYER1LO) pins 9 and 10
      Off state voltage. Vceoff 30v max.
      Leakage current. Iin 5µA.
      On state voltage. Vcesat 0.5v max.
      On state current. Ic 30mA max.
      Emitter voltage. Ve 0V min.

      Any help would be appreciated.
