bit 41…bit 44
MSBit Data in first position LRC
LRC:
4 bits = XOR between each number
Data:
MSByte hexdecimal numbers in first position. Each hexadecimal number at 4 bits, MSBit in first position
Example: Entered code : 2514 - Hexadecimal value : 0000009D2 in Wiegand 44 format
FORMAT
1) 16 bits at zero
2) Start code SS
(B)
+ odd parity bit.
3) 10 or 13 reverse BDC nibbles, corresponding to the ID code + odd parity bit.
4) Transmission end code ES
(F)
+ odd parity bit.
5) Linear redundancy code of previous nibbles, except start zeros + odd parity
bit.

LINES
Two lines :
DATA & CLOCK normally at «1»
(5Vcc)
that produce pulses at «0»
(0,4Vcc)
for 1/3 of the clock period, of 1 ms. DATA at «0» to send «1» logical and
at «1» to send a logical «0» .
Longest possible code :
99999999
NOTE: If the code of the tag cannot be represented in BDC 10 characters, it is
recommended to use format BCD 13.
