Precaution 2
The HEX code of Wiegand data is derived from the user code. Do NOT make an user code starting with “0”, such
as 02345. Otherwise it will cause confusion in Hex code with the user code in same number without “0” at the front.
Please see examples B & C below for the explanations. This precaution applies to 26-bit, 34-bit and 37-bit Wiegand
data.
Example A shows a 34-bit Wiegand data derived from an 8-digit User Code 12345678.
Example B and C show the Wiegand outputs derived from User Codes 1234 and 00001234. Their Hex binary codes
derive from the two User Codes in Wiegand format are identical and can not be discriminated from each other.
EXAMPLE:
The keyed-in Code is 1 2 3 4 5 6 7 8
The Code in Decimal Number: 1 2 3 4 5 6 7 8
The Code 1 2 3 4 5 6 7 8 Equivalent to Hex Number: B C 6 1 4 E
E 0 0 B C 6 1 4 E O
An Even Parity Bit of 0 0 B C = 1 An Odd Parity Bit of 6 1 4 E = 0

The keyed-in Code is 1 2 3 4
The Code in Decimal Number: 1 2 3 4
The Code 1 2 3 4 Equivalent to Hex Number: 4 D 2
An Even Parity Bit of 0 0 0 0 = 0 An Odd Parity Bit of 0 4 D 2 = 0
