Offset
Is a numeric character up to 9 digits in length. The offset is normally a value of zero; however, it can be a numeric value that is automatically added to the card number field. For example, suppose that you have two different card formats, with different facility codes, but with the same range of imprint numbers (1 to 100). Without the offset, you would have two different cards with the same imprint number. By using the offset, you can automatically adjust the imprint value of one of the formats by the offset value. If the offset value of one of the formats is changed to 1,000,000 then the card imprint range for that format is now 1,000,001 to 1,000,100. The values that you would enter into the cardholder's record would be the adjusted value (a range of 1,000,001 to 1,000,100). The offset of 1,000,000 and the card number range of 1 to 100 are just examples and may differ for your application.
MSC specific option to transform MS presented card into a number that can be parsed with individual facility code and imprint fields. One ability of this feature is to allow specifying a fixed facility code for Keri MS credentials, and enroll as Imprint(/Internal) formats, an option not usually available for Keri MS.
Corporate Offset
The corporate offset changes how the card number is computed for this format. The card number is offset by multiplying the facility code by the offset value.
Ignore Even Parity
The even parity bit of the card number is ignored and not processed by the controller.
This still requires you to specify the designated start bit for even parity.
Ignore Odd Parity
The odd parity bit of the card number is ignored and not processed by the controller.
This still requires you to specify the designated start bit for odd parity.
Trim Unused Bits (MSC-Specific Option)
Takes the internal format XXXXFFFFFCCCCCCCCCCCCCCCCCCCCCCX and can treat the inside bits as a full card number XXXXCCCCCCCCCCCCCCCCCCCCCCCCCCCX as something Borealis can compute, and the MSC controller will ignore the other bits. With the option set, calculation is allowed so can be enrolled by facility code and imprint.
