- 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.

- 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.
