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
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
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 0102166A37.

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.
