Wiegand Format Editor view, Wiegand Format tab

This view configures new Wiegand format properties.

NOTE: You cannot edit a card format that is in use. Card formats that are not currently used by any badges display in the Wiegand format editor view and may be edited.

This view opens from the main menu when you click Controller Setup > Access Setup > Card Formats, followed by clicking the Add button () in the Add New Wiegand Format view.

To edit an existing format, double-click the format row in the Card Formats view.

NOTE: You cannot edit a card format that is in use. Card formats that are not currently used by any badge display in the Wiegand format editor view and may be edited.

Links

A Save link and a Wiegand Formats view link are located at the top of the view.

NOTE: A maximum of 256-bit Wiegand format size (card bit length) is supported.

Wiegand Format tab properties

Property	Value	Description
Wiegand Format Name	text	Provides a descriptive title for the Wiegand Format.
Default Facility Code	text	Sets the default `Facility Code` property when assigning a format to a badge. It does not need to match the `Facility Length` property and can be used to pre-load a prefix to be completed during badge creation.
Validation Bits	drop-down list	Selects the level of validation to use with the format. Three options are available: `All`, the most restrictive or secure, validates bits representing all possible areas of the format. `Credential and Facility Code` only validates the Credential and Facility Code bits. `Credential Only`, the least restrictive or secure, only validates the Credential bits.
Bit Length	number (0-256)	Specifies the card format total bit length. This number is the total of all data bits and all parity bits.
Parity Bits	number (0-5)	Specifies how many parity bits are in the format, not the location of the bits. Refer to Format property
Facility Start	number	Specifies the bit position that holds the first bit of the facility code. Refer to Format property
Facility Length	number	Specifies the total number of bits that are dedicated to facility code. Refer to Format property
Credential start	number	Specifies the bit position that holds the first bit of the credential numbers. Refer to Format property
Credential Length	number	Specifies the total number of bits that are dedicated to credential numbers. Refer to Format property
Format	text	Specifies the layout of all the bits, which must agree with the information in the previous parity, facility, and credential properties. 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) Refer to Format property
Parity Layout	one or more additional format properties	Define the expected parity: Odd or Even. Refer to Format property

Format property

Parity Bits may be located anywhere in the format.

The example Format above has two parity bits. It specifies the location of these bits: one in the leading position, and the other in the trailing position.

Facility Start, Facility Length, Credential Start and Credential Length identify where the information starts in the Format, and how many characters are involved.

The Format property identifies the purpose of each bit, which must agree with the Parity Bits, Facility and Credential properties.

For example, if the Parity Bits value is “3,” three instances of the letter “P” must appear in the Format.

Based on the number of Parity Bits, additional Parity Layout properties appear below the Format property. If the value of Parity Bits is zero (0), no Layout properties appear. Parity Layout properties indicate the expected parity: Odd or Even.

The locations of the “E” and “O” characters in the Parity Layout property 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 Layout definition.
In each Parity Layout definition, 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 Code or Credential Number).
Position the first “E” or “O” directly below the “P” in the Format property (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 Format and add additional characters of the same type as required by the definition.
