6] OUTPUT FORMATS 26, 30 AND 44 BIT WIEGAND
Chronograms
Open collector output with internal pulls up 1K at +5V or +12V according the ST4 position.
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 rst 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 Bit 2 to bit 25 Bit 26
Even Parity on bit 2 to bit 13 Data (24 bit)
Odd Parity on bit 14 to bit 25
Exemple: code of the badge is 0100166A37.
1 0001 0110 0110 1010 0011 0111 0
Parity 1 1 6 6 A 3 7 Parity 2
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.

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 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 Bit 2 to bit 29 Bit 30
Even Parity from bit 2 to bit 15 Data (28-bit) Odd Parity from bit 16 to bit 29
Exemple 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.
Exemple 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:
Data: 10 digit code number hexadecimal MSByte rst.
Each hexadecimal digit = 4 bit, MSBit rst.
LRC: 4 bit = OR restricted in between the digit of the data, MSBit rst.
Bit 1 to bit 40 Bit 41 to bit 44
Data MSBit rst LRC
Exemple 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.
