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 fi rst 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 fi rst.
Each hexadecimal digit = 4 bit, MSBit fi rst.
LRC: 4 bit = OR restricted in between the digit of the data, MSBit fi rst.
Bit 1 to bit 40
Data MSBit fi rst
Exemple A: EM badge hexadecimal code: 01001950C3.
0000 0000 0000
0 1
The code number of the card is: 01001950C3 in hexadecimal code.
