The dongleserver ProMAX offers additional reliability and redundancy with two built-in power supplies and two network connections. In addition, the parameters, passwords, and certificates are automatically backed up to an integrated SD card. The dongle server is also equipped with a multi-segment status and fault display for information at a glance. A user makes a connection to a certain dongle through the software tool and uses the license-protected software locally as needed. At this time the dongle cannot be used by another user. Once the user has finished using the software and the connection to the dongle is deactivated, the dongle is free to be used by another user.
