The Wiegand configuration UI in BioStar 1 and 2 are different and may cause some confusion.
If you would like to configure your Wiegand format in BioStar 1 the same as BioStar 2 refer to the sample below to understand the difference.
Below is a sample configuration of 26 bit Standard format.
The total bit configuration is exactly the same and straightforward. This is a 26 bit format so 26 will be input.
The facility code field in BioStar 1 is the undefined blocks.
Hence 1-8 bit position are the facility code blocks.
In BioStar 2, you do not have a visual representation. You would configure the start bit at 1 and end bit at 8 accordingly.
The ID Field in BioStar 1 are the blocks configured as I.
In BioStar 2 you would configure the start and end bit accordingly.
The parity bit positions are represented by E (even) and O (odd) in BioStar 1.
The positions are configured accordingly in BioStar 2 as below
Even parity is the first parity page in BioStar 1. When you calculate for BioStar 2, ignore the even parity bit position (0).
Odd parity is the 2nd page of the parity configuration in BioStar 1. Ignore the odd parity bit position (25) here as well when configuring in BioStar 2.
