Note
Control via automation system: DISA bit must not be set
If you control the reader from an automation system, make sure that the DISA bit is not set
during the firmware update. This prevents an automation system from switching the reader
to RUN.
"Incremental update..." button
The "Incremental update..." button opens a Web page where you can update the firmware.
To do this, you require a vsz file.
An incremental update is only possible to a version in which the version has only changed in
the third digit compared with the previous version.
