Wiegand 125 kHz Proximity Readers
30-bit Wiegand Output
Format 30-bits hexadecimal. The output format is 30-bit Wiegand (Signals: DATA1, DATA0 and CLOCK). The
frame is made of 30-bit and built as follows:
1 - First parity: 1 bit – even parity for the first 14-bit.
Code of the badge: A code is formed from 7 half byte.
Each byte is transferred from bit 7 to bit 0.
2 - Second parity: 1 bit – odd parity for the last 14-bit.
Bit 1
Even parity from bit 2 to bit 15
Example A: Temic card decimal code 689905 (in hexadecimal: A86F1).
1 0000
Parity 1 0
The code number of the card in hexadecimal is 00A86F1.
Example B: EM badge hexadecimal code: 0100166A37.
1 0000
Parity 1 0
The code transmitted in hexadecimal format is 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.
Parité 2 : 0 si le nombre de 1 dans bit 16 à bit 29 est impair,
1 si le nombre de 1 dans bit 16 à bit 29 est pair.
44-bit Wiegand format
44-bit hexadecimal format. The output format from the proximity card reader is 44-bit (Signals: DATA1, DATA0
and CLOCK) and is structured as follows:
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.
Bit to à bit 40
Data MSBit first
Example A: EM badge hexadecimal code: 01001950C3.
0000 0000 0000
0 1
The code number of the card in hexadecimal is 01001950C3.
