Paxton OEM Magstripe reader, Wiegand 26 bit output - Manual (Page 2)

The 26 Bit Wiegand standard is defined as follows;
PSSSSSSSSUUUUUUUUUUUUUUUUP
P= Parity bit
S= Site Code
U= User Code
The first Parity bit is a 1 if it is required to make the total number of bits 1-13 an Even number.
The last Parity bit is a 1 if it is required to make the total number of bits 14-26 an Odd number.
Special cards may be used which comprise a start sentinel followed by 3 digits, a field separator, a further 5 digits
and an end sentinel.
The 3 digits preceding the field separator (=) are taken as the site code and the 5 digits after the field separator
are taken as user code.
Example: - SS 152=27854 ES
Site code : 152 = 10011000 (Binary)
User code: 27854 = 0110110011001110 (Binary)
Accepted token data formats.
ABA standard cards
The data on ABA standard cards comprise a start sentinel followed by 16 digits, a field separator and some
additional characters.
Only the 6 digits before the field separator (=) are used and are transmitted to the controller.
Example: SS 1234567898 765432 = 1478 5236 ES LR
The data (6 digits before =) is therefore 765432
The first 2 digits are then used as the site code and the remaining 4 digits become the user code.
Site Code: 76 01001100 (Binary)
User Code: 5432 0001010100111000 (Binary)
