Data Outputs

 Wiegand Format 26bit output data format

The Wiegand Format 26 bits format is formed by 26 bits of data, including 24 bits user data and 2 parity bits. The first bit is the even parity for the first 12 bits of data ( bits 1 to 12 ), The last bit is the odd parity over the ending 12 bits of data ( bits 13 to 24 ).
