26-bit Wiegand Output
Format 26-bit hexadecimal. The output format is 26-bit Wiegand (Signals: DATA1, DATA0 and CLOCK)
The frame is made of 26-bit and built as follow:
1 - First parity: 1-bit – even parity for the first 12-bit
Code of the badge: 6 half byte represent the last 6 digit of the code (4bit = 1 digit of a code)
Each byte is transferred from bit 7 to bit 0.
2 - Second parity: 1 bit – odd parity for the last 12-bit.
Bit 1
Even Parity on bit 2 to bit 13
Exemple: code of the badge is 0100166A37.
1 0001 0110 0110
Parity 1 1 6
The code transmitted is in hexadecimal format 166A37
Parity 1: 0 if the number of 1 in bit 2 to bit 13 is even,
1 if the number of 1 in bit 2 to bit 13 is odd.
Parity 2: 0 if the number of 1 in bit 14 to bit 25 is odd,
1 if the number of 1 in bit 14 to bit 25 is even.

Wiegand 125Khz Proximity Readers
30-bit Wiegand Output
Signals output in open collectors with pull up in 30-bit hexadecimal format. The output format
from the proximity reader is 30-bit wiegand (Signal: DATA1, DATA0 and CLOCK) and is structured as follow:
1 - First parity: 1 bit – even parity for the first 14-bit
Code: A code is formed from 7 half byte.
Each byte is transferred from bit 7 to bit 0.
2 - Second parity: odd parity for the last 14-bit.
Bit 1
Even Parity from bit 2 to bit 15
Exemple A: Temic card decimal code: 689905 (in hexadecimal: A86F1).
1 0000
Parity 1 0
The code number of the card is 00A86F1 in hexadecimal.
Exemple B: EM badge hexadecimal code: 0100166A37.
1 0000
Parity 1 0
The code transmitted is in hexadecimal format 0166A37.
Parity 1: 0 if the number of 1 in bit 2 to bit 15 is even,
1 if the number of 1 in bit 2 to bit 15 is odd,
Parity 2: 0 if the number of 1 in bit 16 to bit 29 is odd,
1 if the number of 1 in bit 16 to bit 29 is even.
44-bit Wiegand Format Output
44-bit hexadecimal format. The output format from the proximity reader is 44-bit (Signal: DATA1, DATA0 and CLOCK)
and is structured as follow:
Data: 10 digit code number hexadecimal MSByte first.
Each hexadecimal digit = 4 bit, MSBit first.
LRC: 4 bit = OR restricted in between the digit of the data, MSBit first.
0 Bit 1 to bit 40
Data MSBit first
Parity 2
Exemple A: EM badge hexadecimal code: 01001950C3.
0000 0000 0000
0 1
The code number of the card is: 01001950C3 in hexadecimal code.
