Cable Pinout (Looking at cable end)

NC = No Connection (Leave Disconnected)

1. White – Ground
2. Green – Clock
3. Yellow – Latch
4. Black – Data
5. NC
6. NC
7. Red – 5V

NOTE: For NTSC only setups, the Resistor PCB can be ignored entirely, with all connections direct from the cable to the board
* 5V input pins are on the side of header J6 that is towards the centre of the LevelShifter PCB
** GND input pins are on the side of header J6 that is towards the edge of the PCB

  1. Level Shifter Input wiring [Player 1]

    1. Connect GND (White / Pin 1 of Player 1) to a GND input pin**
    2. Connect Clock1 (Green / Pin 2 of Player 1) to the Resistor PCB, then to B2A on header J2
    3. Connect Latch1 (Yellow / Pin 3 of Player 1) to the Resistor PCB, then to B1A on header J2
    4. Connect Data1 (Black / Pin 4 of Player 1) to A1Y on header J1
    5. Connect 5V (Red / Pin 7 of Player 1) to a 5V input pin*

  2. Level Shifter Input wiring [Player 2]

    1. Connect GND (White / Pin 1 of Player 2) to a GND input pin**
    2. Connect Clock2 (Green / Pin 2 of Player 2) to the Resistor PCB, then to B3A on header J2
    3. Connect Data2 (Black / Pin 4 of Player 2) to A2Y on header J1
    4. Connect 5V (Red / Pin 7 of Player 2) to a 5V input pin*

  3. Output wiring [Level Shifter to RetroRosetta Core]

    1. Connect GND of LevelShifter** to RetroRosetta pin 17A
    2. Connect 5V of LevelShifter* to RetroRosetta pin 19D
    3. Connect 3.3V of LevelShifter to RetroRosetta pin 14A
    4. Connect A1A to RetroRosetta pin 6B [IO19]
    5. [2 Player] Connect A2A to RetroRosetta pin 2B [IO22]
