You can configure access to be granted only to credentials with specific card formats and facility codes or with specific raw card formats when the SIO board loses connection with the Mercury controller.

Before you begin

  • CAUTION:
    Configuring access to be granted through facility codes or card formats when the SIO board loses connection with the Mercury controller greatly reduces the security of your system. When this is configured, no activity trails are available. Any events that occur while in the SIO board isn’t connected to the Mercury controller aren’t recorded.
  • Learn about how granting access through card formats and facility codes affects access decisions.
  • To use a custom Wiegand card format, create it in Genetec™ Configuration desktop, and then export it to an XML file. The custom card format must be configured with a Wiegand field named Facility Code. The mask of the Wiegand field must be an ascending sequence of bits, up to 63 bits long.
    Example: The following example shows a Wiegand card format with a sequential facility code configured in the General settings view of the Access control task:

Procedure

To grant access through a card format and facility code:

  1. Sign in to the Genetec Cloudlink appliance, and then go to the Synergis Softwire portal.
  2. Click Configuration > Mercury controller settings.
  3. Click the Door behavior for offline SIO boards tab from the side menu, and select Facility code.
  4. (Optional) To use a custom card format, do the following:
    1. In the Custom Wiegand card formats section, click Select file, and then select the XML file that you exported from Genetec Configuration desktop.
    2. Click Import card format.
    The custom card format is listed in the Custom Wiegand card formats section, and can now be selected from the Card format drop-down in the Door behavior for offline SIO boards section.
    Example:
    Imported custom Wiegand card format on the Mercury controller settings page of the Synergis Softwire portal.
  5. From the Card format list, select a card format, and then enter a value in the Facility code field.
  6. Click Add.
    The configured card format and facility code are added to the list.
  7. Click Save, and then perform a software restart.
    Access is only granted to credentials that match both the card format and facility code.

To grant access through a raw custom card format:

  1. Sign in to the Genetec Cloudlink appliance, and then go to the Synergis Softwire portal.
  2. Click Configuration > Mercury controller settings.
  3. Add the custom card format by doing the following:
    1. Click the Long credential formats tab from the side menu, and then enter the credential length you want to use.
    2. Click Add.
    The custom card format can now be selected from the Card format drop-down in the Door behavior for offline SIO boards section.
  4. Click the Door behavior for offline SIO boards tab from the side menu, and select Facility code.
  5. From the Card format drop-down, select the custom card format, and then click Add.
    Example:
    Door behavior for offline SIO boards section on the Mercury controller settings page of the Synergis Softwire portal showing a custom card format.
  6. Click Save, and then perform a software restart.
    Access is only granted to credentials that match the custom card format, regardless of the facility code.
