Note A: In case of old I/O board (split power connector) and if your
Wiegand/Dataclock peripheral has open drain outputs, a signal adaptation is
required, as follows:
D0 Wiegand IN signal:
Pull up 10K Ohms to +12Volts
Pull down 4.7K Ohms to GND
D1 Wiegand IN signal:
Pull up 10K Ohms to +12Volts
Pull down 4.7K Ohms to GND
