KAHR PRO-5VDC regulator for WPC games

The Pro daughterboard implements the same reset-preventing solution as the classic daughterboard but also includes additional circuitry to monitor your Power Driver Board (PDB). The 2018 edition monitors the driver board's 5v and 12v supplies! Simply inspect the LEDs to quickly determine PCB power supply functionality. How to read the LEDs:

Green LED lit means both your 12v and 5v power supplies are stable
Flashing Green LED 5v supply exceeded 5.6v
Red LED lit means at some point, since turning your machine on, the PDB 5v power supply dipped below the voltage that would have triggered a reset had the daughter-board not been present
Flashing Red LED means the 5v supply fell very low and needs maintenance
Blue LED lit means the 12v supply is weak - at some point since turning your machine on the PDB 12v regulated supply dropped below 9 volts
Red and Blue LEDs lit means both supplies on your PCB have triggered alerts.
