    1. Pin 1 : DC GND

      This pin is the main digital and analog ground of the MKP. This is also the return circuit for the 28VDC power.

    2. Pin 2 : 28VDC-IN

      Main power input.

    3. Pin 3 : CHASSIS

      The chassis connection should be connected to chassis ground.

    4. Pin 4 : RESERVED

      For future use. Leave pin open.

    5. Pin 5 : PWM 1 POWER

      5VDC Power for the remote light plate. The circuit can drive 200mA and will trip (turn off) at 400mA. The circuit will reset when fault has been resolved.

    6. Pin 6 : PWM 1 RTN

      This is the PWM controlled return circuit for the light plate.

    7. Pin 7 : ENTER-KEY-OUT

      When ENTER key is pressed this is driven to GND. 

    8. Pin 8 : PWM 2 POWER

      5VDC Power for the remote light plate. The circuit can drive 200mA and will trip (turn off) at 400mA. The circuit will reset when fault has been resolved.

    9. Pin 9 : PWM 2 RTN

      This is the PWM controlled return circuit for the light plate.

    10. Pin 10 : RESERVED

      For future use. Leave pin open.

    11. Pin 11 : PWM 3 POWER

      5VDC Power for the remote light plate. The circuit can drive 200mA and will trip (turn off) at 400mA. The circuit will reset when fault has been resolved.

    12. Pin 12 : PWM 3 RTN

      This is the PWM controlled return circuit for the light plate.

    13. Pin 13 : RESERVED

      For future use. Leave pin open.

    14. Pin 14 : RESERVED

      For future use. Leave pin open.

    15. Pin 15 : RESERVED

      For future use. Leave pin open.

    17. Pin 17 : ARINC-429-IN-B

      ARINC-429-IN-B

    18. Pin 18 : RESERVED

      For future use. Leave pin open.

    19. Pin 19 : ARINC-429-OUT-A

      ARINC-429-OUT-A

    20. Pin 20 : ARINC-429-OUT-B

      ARINC-429-OUT-B

    21. Pin 21 : RESERVED

      For future use. Leave pin open.

    22. Pin 22 : RESERVED

      For future use. Leave pin open.
