6.4.2 Wiegand26 Format
1) MSB is even parity bit, LSB is odd parity bit.
2) The bits for calculating even parity are within the first 12 bits.
3) The bits for calculating odd parity are within the last 12 bits.
For example:
Data Hex: D4 1B 81
Data Binary: 11010100 00011011 10000001
MSB: 1 from 11010100 0001
LSB: 0 from 1011 10000001
Output: 1 11010100 00011011 10000001 0
6.4.3 Wiegand32 Format
1) MSB is even parity bit, LSB is odd parity bit.
2) The bits for calculating even parity are within the first 15 bits.
3) The bits for calculating odd parity are within the last 15 bits.
For example:
Data Binary: 001111110101010101010110010000
MSB: 1 from 001111110101010
LSB: 1 from 101010110010000
Output: 1 001111110101010101010110010000 1
6.4.4 Wiegand32e Format
Wiegand32e don’t have odd/even parity bits.
6.4.5 Wiegand34 Format
1) MSB is even parity bit, LSB is odd parity bit.
2) The bits for calculating even parity are within the first 16 bits.
3) The bits for calculating odd parity are within the last 16 bits.
For example:
Data Hex: 89 D4 1B 81
Data Binary: 10001001 11010100 00011011 10000001
MSB: 1 from 10001001 11010100
LSB: 1 from 00011011 10000001
Output:1 10001001 11010100 00011011 10000001 1
