Jantar, a company specialising in access control and security applications, installed
their system incorporating San People's Etherpads at the Ljubljana Airport in Slovenia, and in Rome, Italy.
The Jantar controllers are usually connected to the Monitoring and control PC with a serial link. At Ljubljana Airport , the various buildings are
physically too far apart to use a serial cable, however, an existing Ethernet network was available in all the buildings. One EtherPAD is located at
each remote site, connecting a controller to the existing WAN. The figure below shows the details of the equipment at each location. Each location
has objects (DHL-hangar, Police, Sales), and each object has a number of controllers. The low level in the tree represents card readers.
The EtherPAD has a specific IP address on the network and it is possible to configure and monitor the controllers remotely via the EtherPAD connection
