INTERFACE OUTPUT INTRODUCTION

Wiegand Interface: VCC D1 D0 GND FOR

VCC	5V power supply
D1,D0	Wiegand data output DATA1, DATAO
GND	Power supply ground
FOR	Format selection, default is 26BIT, and connect with GND to output 34BIT

WIEGAND
When a card is sensed, the serial number of the card will be output through Data0 and Data1 data lines.
Both Data0 and Data1 are high without data output.
Data bit 0 generates a low level with a width of 400us on the Data0 line.
Data bit 1 generates a low level with a width of 400us on the Data1 line.
The length of each bit of data is 2400us
Each card has a string of 4-byte serial numbers, and we output the last three bytes.
Add the first 12 even parity bits in the front and the last 12 odd parity bits in the back, a total of 26 bits of data.
Card No.: 6B 3D 12 D6
The output data is: 3D 12 D6.

Weigand 26 Code:

0	111101	10010	11010110	1
Even check	3D	12	D6	Odd check

Weigand 34 Code:

0	1101011	111101	10010	11010110	0
Even check	6B	3D	12	D6	Odd check

UART Interface: VCC RXD TXD GND FOR
