Digit Input
D1+ and D1- are the positive and negative nodes of the external signal inputs.
D1+ = 3V ~ 12V,
D1- = GND DIGIT-INPUT1 = High
D1+ = 0V ~ 2V,
D1- = GND DIGIT-INPUT1 = Low
D2+ and D2- are the positive and negative nodes of the external signal inputs.
D2+ = 3V ~ 12V,
D2- = GND DIGIT-INPUT2 = High
D2+ = 0V ~ 2V,
D2- = GND DIGIT-INPUT2 = Low
