Note
Incompatibility with previous versions with PLUG inserted
During the installation of a previous version, the configuration data can be lost. In this case,
the device starts up with the factory settings after the firmware has been installed. In this
situation, if a PLUG is inserted in the device, fol
lowing the restart, this has the status "Not
Accepted" since the PLUG still has the configuration data of the previous more up
-to-date
firmware. This allows you to return to the previous, more up
-to-date firmware without any
loss of configuration data.
the original configuration on the PLUG is no longer required, the PLUG can be deleted or
rewritten manually using "System > PLUG".
