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 follows:
1 - First parity: 1-bit – even parity for the fi 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.
Bit 1
Even Parity on bit 2 to bit 13
Exemple: code of the badge is 0100166A37.
1 0001
Parity 1 1
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.
