Wiegand Data = Valid Data + Parity Data
Total Length: Wiegand data length.
Transportation Rule: 4 bytes. Display the combination types of valid data. The example displays the combination
of Card ID and Manufacturer Code. The valid data can be single rule, or combination of multiple rules.
Parity Mode: Valid parity for wiegand data. You can select either odd parity or even parity.
Odd Parity Start Bit, and Length: If you select Odd Parity, these items are available. If the odd parity start bit is 1,
and the length is 12, then the system will start odd parity calculation from bit 1. It will calculate 12 bits. The result
will be in bit 0. (Bit 0 is the first bit.)
Even Parity Start Bit, and Length: If you select Even Parity, these items are available. If the even parity start bit is
12, and the length is 12, then the system will start even parity calculation from bit 12. It will calculate 12 bits. The
result will be in the last bit.
XOR Parity Start Bit, Length per Group, and Total Length: If you select XOR Parity, these items are available.
Depending on the table displayed above, the start bit is 0, the length per group is 4, and the total length is 40. It
means that the system will calculate from bit 0, calculate every 4 bit, and calculate 40 bits in total (10 groups in
total). The result will be in the last 4 bits. (The result length is the same as the length per group.)
Card ID Start Bit, Length, and Decimal Digit: If you use the transformation rule, these items are available.
Depending on the table displayed above, the card ID start bit is 0, the length is 32, and the decimal digit is 10. It
represents that from bit 0, there are 32 bits represent the card ID. (The length here is calculated by bit.) And the
decimal digit length is 10 bits.
Site Code Start Bit, Length, and Decimal Digit: If you use the transformation rule, these items are available. For
detailed information, see the explanation of the card ID.
OEM Start Bit, Length, and Decimal Digit: If you use the transformation rule, these items are available. For detailed
information, see the explanation of the card ID.
Manufacturer Code Start Bit, Length, and Decimal Digit: If you use the transformation rule, these items are
available. Depending on the table displayed above, the manufacturer code start bit is 32, length is 8, and decimal
digit is 3. It represents that from bit 32, there are 8 bits are manufacturer code. (The length here is calculated by
bit.) And the decimal length is 3.
