Gateway function - SmartRelay 3 system

The SREL3 ADV system can also be used as a gateway for the virtual network, no matter whether a relay contact is used or not. Any identification medium which is logged onto one of up to three readers is updated. In doing so, a difference must be made between network-dependent and network-independent functions.

Network-independent

  • Loading time budgets: Users are able to re-upload their time budgets at any time without the network.
  • Automatic blacklist distribution: IDs which have already been flagged for blocking in the controller are also distributed in the virtual network without a network connection.

Partially network-independent

When the network connection is re-established, the controller transmits information which was collected during the outage:

  • Feedback signals from blacklist broadcasts: Locking devices which have received authorisation changes for transponders emit a feedback signal. This feedback signal is transmitted to the controller via the virtual network.
  • Battery warnings: Locking devices which have low batteries transmit a battery warning to the controller via the identification media in the virtual network.
  • Physical access lists: The smart card physical access list are read and saved by the controller independently of the network.

Network-dependent

If there is a network connection, other virtual network functions are available on the gateway:

  • Issuing of individual authorisations: When an identification medium has logged on, the controller retrieves the latest authorisation information for the transponder concerned from the VN host server via the network. The authorisation changes are updated on the transponder via the reader if necessary.
  • Configuration changes: The controller retrieves configuration changes to identification media, such as a time group change, from the VN host server.
  • Issuing of individual blacklist IDs: Up to two IDs to be blocked can also be added to selected identification media in the virtual network. To do so, the controller retrieves the IDs to be blocked from the VN host server when such an identification medium logs on.
