EFFFFFFFFFFFFFFFFFFCCCCCCCCCCCCCCCCO
It consists of 36 bits of binary code. The 1
st
bit is the even parity bit of the 2
nd
to
18
th
bits, while the 36
th
bit is the odd parity bit of the 19
th
to 35
th
bits. The 2
nd
to
19
th
bits are the device codes, and the 20
th
to 35
th
bits are the card numbers.

Wiegand Output
Function Description:
Function
Descriptions
Wiegand Format
Its value can be 26 bits, 34 bits, 36 bits, 37 bits, and 50 bits.
Wiegand Output Bits
After selecting the required Wiegand format, select the corresponding
output bit digits of the Wiegand format.
Failed ID
If the verification fails, the system will send the failed ID to the device and
replace the card number or personnel ID with the new one.
Site Code
It is similar to the device ID. The difference is that a site code can be set
manually and is repeatable on a different device. The valid value ranges from
0 to 256 by default.
