30-bit Wiegand Output
Structure and description of the code :
DGLPWLC - DGLPFNWLC - DGLIWLC - DGLIFWLC > Place the ST5 jumper on 2
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 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: 1 bit – odd parity for the last 14-bit
Bit 1 Bit 2 à bit 29 Bit 30
Even Parity from bit 2 to bit 15
Data (28-bit)
Odd Parity from bit 16 to bit 29
Example A : Temic card decimal code: 689905 (in hexadecimal: A86F1).
1 0000 0000 1010 0110 0110 1111 0001 0
Parity 1 0 0 A 8 6 F 1 Parity 2
The code number of the card is 00A86F1 in hexadecimal
Example B : EM badge hexadecimal code: 0100166A37
1 0000 0000 0001 0001 0110 1011 0110 1
Parity 1 0 0 6 6 A 3 7 Parity 2
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:
1 - Data: 10 digit code number hexadecimal MSByte rst . Each hexadecimal digit = 4 bit, MSBit rst
2 - LRC : 4 bit = or restricted in between the digit of the data, MSBit rst.
Bit 1 à bit 40 Bit 41 à bit 44
Data MSBit rst LRC
Example A : EM badge hexadecimal code: 01001950C3.
0000 0000 0000 0000 0001 1001 0101 0000 1100 0011 0011
01001950C33
The code number of the card is: 01001950C3 in hexadecimal code.
