displays and their UDB version.
Databases
The upper table on the diagnotics page gives an account of the
various automatically synchronised databases that ensure all
Lowrance displays are using the same user settings and data.
Each unit stores the database locally, so that all information is
available if the device is run in standalone. Databases can become
unsynchronized when one or more displays in a multi display
network are not powered up while other displays are being
operated. Creation of waypoints, routes, and altering global settings
all a ect databases. When ‘Dirty’ is displayed, the unit has identi ed
that its database is older than that of another device on the
network. ‘Dirty’ should clear within seconds of both devices being
powered up, and the databases synchronizing. If it does not clear, it
is recommended that all devices have the power cycled.
If any database will not synchronize, it may be necessary to use the
Restore Defaults option found under the System menu. Backup
any user settings if required - see “Backing up and Importing user
data” on page 50. The Restore Defaults operation should be
done one device at a time, with all other devices powered o . Once
a device is defaulted, it should be turned o until all other devices
have also been defaulted.
IP addresses
The lower table shows the IP address of the display being viewed
at the top, and is identi ed with “This display” next to it. Other
connected displays are shown below it. The function of the display
labeled as “Master” is invisible to the end user - It manages database
synchronization, however this task automatically shifts to another
display if the current master is shut down. The IP address list only
refreshes after all devices on the network have been powered
down - a single device that is shutdown on the network will not be
removed from the table shown on other devices. When powering
up a system that has been completely shutdown, a network
connectivity issue can be identi ed if a display does not show any
other IP addresses than its own.
The ‘UDB version’ is dependant on the software version installed on
the display. It will never change on its own, unlike the ‘Version’ of
the Databases on the upper table. It is preferable to have all UDB
versions the same. This can usually be acheived by loading the latest
software on to your display - refer to “HDS Gen3 software upgrades”
on page 51.
