INTERFACE
- The output format is 26-bit Wiegand (Signals: DATA1, DATA0 and CLOCK),
- Output signal in open collectors (pull up of 2.2K in +5V) 26-bit hexadecimal output format.
The frame is made of 26-bit and built as follow:
- First parity: 1-bit – even parity for the fi rst 12-bit,
- User Code: 3 half of a byte represent the code entered. Each byte is transferred from bit 7 to bit 0,
- Second parity: 1-bit – odd parity for the last 12-bit.
Bit 1
Even parity on bit 2...bit13
EXAMPLE A 4-DIGIT CODE: « 1 3 5 0 » Then « B »

Parity 1
0
The code is transmitted in hexadecimal: 671350
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.
10] 30-BIT WIEGAND FORMAT
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 fi rst 14-bit
Code : A code is formed from 7 half byte.
Each byte is transferred from bit 7 to bit 0.
