52 ProCapture-T & PRoRF-T User Manual
1. When the output content is set to user ID, the Wiegand output of the system is as follows after the user
passes the verification.
0 0 0 0 0 0 0 0 0 0 0 1 1 0 0 0 0 0 0 1 1 1 0 0 1 1
Even parity check bit User ID = 12345 in binary system Odd parity check bit
2. When the output content is set to card number, the Wiegand output of the system is as follows after
the user passes the verification.
1 1 1 0 0 1 1 0 0 0 0 1 0 0 0 1 1 1 1 0 1 0 0 0 0 0
Even parity check bit User ID = 0013378512 in binary system Odd parity check bit
3. When the verification fails, the Wiegand output of the system is as follows:
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0
Even parity check bit Failure ID = 1 in binary system Odd parity check bit

Note: When output content is beyond the preset range of the Wiegand format, the low-order bits
are reserved and high-order bits are discarded. For example, if a user ID is 888 888 888, which is 110 100
111 110 110 101 111 000 111 000 in binary system, the last 24 bits, that is, 111 110 110 101 111 000 111
000 are outputted and the first 6 bits 110 100 are discarded because the Wiegand26 format supports 24
bits of output content.
16.2.2 Wiegand 34 Introduction
The system provides the embedded Wiegand 34-bit format.
Composition of the Wiegand 34-bit format: 2-bit parity check bits and 32-bit output content (user ID or
card number). The 32-bit binary code can indicate 4 294 967 296 (0-4 294 967 295) different values.
