Creating (or editing) a card format
The popular Wiegand format provides many options. This procedure documents how to use the Wiegand Format Editor to create
a Wiegand care format.
Prerequisites: You are connected to the controller station and working in the web UI. If you are creating your own format,
you have the specification that defines the format properties.
- Click .The Card Formats view opens.
- Do one of the following:
- To create a new default format, click the Add From Default Card Formats button (
), and select a default format from the list and click Ok.A default format is useful if you deleted a format and want it back, or if you upgraded your system and do not already have
these formats available. - To design your own card format, click the Add button (
).
- To edit an existing format, select the format row, click the Hyperlink button (
) and click the Wiegand Format tab.
NOTE: You cannot edit or delete a card format that is in use (assigned to a badge). In-use card formats display as read-only in the View Existing Wiegand Format view. Card formats that are not currently associated with a badge display in the Wiegand Format Editor view and may be edited.
If you clicked the Add button the Wiegand Format Editor (Add New Wiegand Format) view opens to the Wiegand Format tab.
- To create a new default format, click the Add From Default Card Formats button (
- Carefully fill in each property and click Save.Parity Bits specifies the number of parity bits in the format. It does not identify the bit location(s).
- Define
Facility StartandFacility Length, as well asCredential StartandCredential Length. - Enter the format characters in the
Formatproperty.
Valid format characters include:
- P – Parity bit (an extra bit added for error detection)
- F – Facility code bit
- N – Credential number bit
- 0 – Constant character of 0 (zero)
- 1 – Constant character of 1 (one)
Based on the number ofParity Bits, additionalParity Layoutproperties appear below theFormatproperty. If the value ofParity Bitsis zero (0), no Layout properties appear.Parity Layoutproperties indicate the expected parity: Odd or Even.
The locations of the “E” and “O” characters in the
Parity Layoutproperty designate the bits that are used to calculate the parity sum. Follow these rules as you enter these characters:- E – indicates that an even number of ones (1) is required to verify transmission accuracy.
- O – indicates that an odd number of ones (1) is required to verify transmission accuracy.
- Do not combine “E” and “O” characters in a single
Parity Layoutdefinition. - In each
Parity Layoutdefinition, at least one parity bit character must align vertically beneath a credential bit or facility code bit. Additional characters are not required to align with any particular character, however, at least one character must be below a data field (Facility CodeorCredential Number). - Position the first “E” or “O” directly below the “P” in the
Formatproperty (Parity Bit-0 Alignment and Parity Bit-1 Alignment for right-to-left validation). Add additional characters of the same type, as required by the parity format definition. - Align an additional “E” or “O” vertically under any additional parity bit (P) in the
Formatand add additional characters of the same type as required by the definition.
