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
D3+ and D3- are the positive and negative nodes of the external signal inputs.
D3+ = 3V ~ 12V,
D3- = GND
DIGIT-INPUT3 = High
D3+ = 0V ~ 2V,
D3- = GND
DIGIT-INPUT3 = Low
D4+ and D4- are the positive and negative nodes of the external signal inputs.
D4+ = 3V ~ 12V,
D4- = GND
DIGIT-INPUT4 = High
D4+ = 0V ~ 2V,
D4- = GND
DIGIT-INPUT4 = Low
