Description

Wiegand format is a string of predefined bits. In simpler terms, it is the arrangement of binary card data and is required to analyze the data received from the input, and before sending, the data will be put in to a predefined format. Wiegand strings consist of even parity, odd parity, facility code and ID codes. INVIXIUM devices support the following Wiegand formats:

  • 26-bits standard format
    The Standard 26-bit Format is an open format. It is widely used by various industries, and is available from many sources. Almost all access control systems accept the Standard 26-bit Format.
  • Pass-Thru Wiegand
    This format is a customized format as compared to the 26-bit standard format. This Wiegand format string does not contain any parity bits and Facility code bits, the format string of this Wiegand type will only contain ID codes.
  • Custom Wiegand
    In custom Wiegand format, all parts of Wiegand string are customizable. This type of Wiegand format contains parity bits and ID code bits in the Wiegand format string. The maximum length of a custom Wiegand format is 512 bits. Custom Wiegand format gives complete freedom to the admin to create a Wiegand format. Admin can specify any number of user fields, can have any number of ID bits and can have a maximum of four even parity and four odd parity bits.

Creating a Custom Wiegand Format for MiFARE 32BIT CSN

  • Click CONFIG tile >> Wiegand app to open the Wiegand settings.
  • Click Manage Wiegand on the bottom left corner.
  • Under manage, click on create button and choose “Custom” option.
  • Give the name of the custom Wiegand i.e. MiFARE 32BIT CSN, and define total bits as 32 Bits where all the 32 bits are ID bits.
  • Click Next and hit Save button to save these changes.
  • Now select the new option listed for MIFARE 32BIT CSN, click on Upload drop down to click on “Selected”, select the device to send these settings to, and click OK.

Wiegand Output

INVIXIUM devices have Wiegand OUT lines to send Wiegand data to access control panels. When the user is authenticated, device will put user ID into configured Wiegand format and write this Wiegand string on Wiegand OUT lines. Upon reception of Wiegand data, the panel will decide whether door should be opened or not. The device will send Wiegand data on Wiegand OUT lines for following events:

  • ID Type: The user can choose ID Type as User ID, or Prox Card ID, or Smartcard ID. Based on the selection the Wiegand string will be sent over Wiegand out lines.
  • Duress: The user can choose different options for duress such as None, Reverse Output, Standard 26bit or any Custom Wiegand. Based on the selection the Wiegand string will be sent over Wiegand out lines.
  • Identification Success: When the user is identified successfully, device will create Wiegand string based on selected Wiegand format. User ID/Prox card ID/Smart card ID will be used as Wiegand ID. This Wiegand string will be sent over Wiegand out lines.
  • Identification Fail: When the user identification fails, device will create Wiegand string based on selected Wiegand format. Zero (Not any user identified) value will be used as Wiegand ID. This Wiegand string will be sent over Wiegand out lines.
  • Verification Success: When the user is verified successfully, device will create Wiegand string based on selected Wiegand format. User ID/Prox card ID/Smart card ID will be used as Wiegand ID. This Wiegand string will be sent over Wiegand out lines.
  • Verification Fail: When the user verification fails, device will create Wiegand string based on selected Wiegand format. User ID/Prox card ID/Smart card ID value will be used as Wiegand ID. This Wiegand string will be sent over Wiegand out lines.
  • Anti-Shock: When anti-shock alarm occurs, the device will create Wiegand string based on selected Wiegand format. Device ID/Device Serial Number/ Device Name will be used as Wiegand ID. This Wiegand string will be sent over Wiegand out lines. Default format for anti-shock is “IXM 82 bits device S/N”.
  • Heart Beat: When anti-shock alarm occurs, device will create Wiegand string based on selected Wiegand format. Device ID/Device Serial Number/ Device Name will be used as Wiegand ID. This Wiegand string will be sent over Wiegand out lines.
  • User Not Found: When the user is not found on device, device will create Wiegand string based on selected Wiegand format. Entered User ID will be used as Wiegand ID. This Wiegand string will be sent over Wiegand out lines.

Find the below screenshot for the output options to configure the output from the IXM devices

Smartcard serial number enrollment

While enrolling users, the admin will be required to add information about the card the user will be using. Follow the steps below to enroll users with their respective card details.

  • Click USERS tile >> Start Enrollment app.
  • Provide the necessary information of the user like ID, Name, access rules etc…
  • Now click the “Smart card ID Read” icon to place the card and let the device read the card serial to add for that particular user.
