Wiegand Interface Protocol Wiegand interface is widely used in the access control industry and is a de facto industry standard. It is sent through two data lines, DATAO (D0) and DATA1 (D1). At present, the Wiegand 34 and Wiegand 26 interfaces are the most used. The data format of the two is the same, but the number of bits sent is different. In Wiegand 34 format, the 4-byte card number is returned, with the high byte of the card number first; in Wiegand 26 mode, the 3-byte card number is returned, the highest byte is discarded, and the high byte of the card number is first. The standard Wiegand 26 format is shown in Figure 4.1, which consists of 24 card numbers, 1 even parity bit, and 1 odd parity bit. The upper 12 bits of the card number are checked for even, and the lower 12 bits are checked for odd. The sending sequence starts from the high bit (bit7 of each byte). The sending rule is: DATA0 and DATA1 keep high level at the same time when there is no signal. If the next bit of data is 0, a 200us (definable) will appear on the DATAO data line. low level, the signal on the DATA1 data line remains unchanged. If the next bit of data is 1, a 200us (definable) low level appears on the DATA1 data line, DATA0 The signal on the data line remains unchanged. Outside the 100us low level, DATAO and DATA1 are always high. The transmission period of each bit of data is 1ms (definable).
Serial (UART) Protocol
The data format of one frame of UART interface is: 1 start bit, 8 data bits, no parity bit, 1 stop bit. Baud rate selectable: 9600bps or 19200bps. The frame length is fixed to 12 bytes.
