module (e.g. 4G radar) will automatically start working, and relay data between the two
devices.
Diagnostics
The UDB (User Data Base) tab on the diagnostics page, provides information on Ethernet
activity, as shown below.
The
Reset Display List
option can be used to refresh the list of connected displays and their
UDB version.
Databases
The upper table gives an account of the various automatically synchronised databases that
ensure units are all 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 unsynchronised when one or more displays in a multi display
network are not powered up while other displays are being operated. Creation of waypoints,
routes, tracks, and altering global settings all affect databases.
When the check-box
Dirty
is selected, the unit has identified that its database is older than
that of another device on the network. The check-box should clear within seconds of both
devices being powered up, and the databases synchronising. If it does not clear, it is
recommended that all devices are power cycled.
IP address
The lower table shows the IP address of the display being viewed (top of list), the Master
display (with
This display
next to it), and any other displays in a multiple display network.
The function of the 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 identified 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 achieved by loading the latest software
on to your display - refer to
"Software upgrades"
on page 43.
Module network light
The network LED on network expansion devices can be useful for determining if the network
is fundamentally operational. No light indicates no connection. A rapidly blinking green LED
means the network module is communicating with another device.
