All sensors are given a Node Description text like DCS #xxx (xxx is the
serial number of the sensor). The user can modify this node description
text if required. Be aware that the node description changes to *Corrupt
Configuration if it has lost the configuration in flash. Contact the factory if
this happens. The configuration is saved in two sectors in flash memory.
A flash sector can be corrupted if the power is lost during the saving of
new configuration. The double flash sector saving ensures that it does not
lose the configuration. If one of the sectors is corrupted, the other sector
is used and also saved to the corrupt sector.
