30-BIT WIEGAND OUTPUT
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 hexadecimal code: 01235A86F1).
0 0011
Parity 1 3
The code number of the card is 35A86F1 in hexadecimal.
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
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
