Ethernet (NETWORK port) | NSS Installation Manual
Ethernet setup
No special setup is required for establishing an ethernet network, it is all ‘plug and play’ . An
NEP-2 connected between an NSS and another network module (e.g. BSM-1) will automati-
cally 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, which is presented in two tables as shown below.
Databases
The upper table gives an account of the various automatically synchronised databases that
ensure Simrad display units (NSS, NSE, NSO, plus B&G Zeus, and Zeus Touch) 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 a ect databas-
es. When the tick box ‘Dirty’ is ticked, the unit has identi ed that it’s database is older than that
of another device on the network. The tickbox 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 have the power cycled.
IP addresses
The lower table shows the IP address of the display being viewed (top of list), the Master
display (with a tick next to it), and any other displays in a multi display network. The function
of the Master is invisible to the end user - It manages database synchronisation, 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 it’s own.
The ‘UDB version’ is dependant on the software version installed on the display. It will never
change on it’s 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 “NSS software updates” on page 50.
Module network light
The network LED on modules such as NEP-2, BSM-1, and RI10, 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.
