reset are the same as for a momentary interruption of power or
pressing the Reset button on the device.
7.3.5 Restoring the factory defaults
Restoring the factory faults allows you to undo all the security
settings made previously. Among other things the Admin user is no
longer password protected. This option thus represents also an
„emergency access" for cases where the password has been
forgotten or in emergencies where the persons who know the
passwords are not available.
Admin authorization is required to reset the factory defaults via
software over the network. The factory defaults can however be
restored through the serial port of the Web-IO by pressing a
key combination after powering up or after a reset.
In any case you should be sure that only authorized persons have
physical access to the unit including the serial port, which may
mean keeping the device in a lockable control cabinet.
