NMEA2000 / SimNet | NSS Installation Manual
NMEA 2000 / SimNet setup
Data setup is required on initial start up of the system, or if any part of the SimNet or NMEA
2000 network has been changed or replaced.
From Network in the main system settings menu you can:
• select SimNet / NMEA2000 data sources either automatically or manually
• con gure instance numbers for SimNet / NMEA2000 devices
• control how device parameters such as backlighting, units and damping are grouped on the
network
• select to share waypoints via SimNet or NMEA2000
• monitor and diagnose both Ethernet and SimNet Networks
• setup NMEA0183 port, baud rate and output data
• control damping
• calibrate water speed derived from a SimNet / NMEA2000 source
Auto Select (Source Selection)
The Auto Select option will look for all sources connected to the NSS system. If more than
one source is available for each data type, the NSS will automatically select from an internal
SimNet priority list.
Make sure all devices are connected and are turned on before selecting the Auto Select
option.
Manual source selection
Manual selection is generally only required where there is more than one source for the same
data.
Group source selection (SIMRAD)
SimNet products such as the NSS, IS20 or AP24 have the ability to;
• use data sources that all other products on the network use, or alternatively use a data source
independently from other units.
• globally change all displays over to a di erent source from any display. (This will only include
products set to Simrad Group mode.)
In order to enable group selection, the device must be set to Simrad.
There are up to 11 categories of sources such as Compass, Navigation, Position etc. Under
each of these categories a display can be set to receive data from sources as part of the
Simrad group or receive the source data independently from the group (None).
Group source selection (NONE)
In some cases it may be desired that an NSS on a network receives the same type of data, but
from di erent sources to that of the rest of the network devices. To do this set the data Group
setting to None, and select a source for the data.
Advanced source selection
This allows the most  exible and precise manual control over which devices provide data to
the NSS.
Some data sources, such as those for fuel level, or engine RPM, can only be changed via the
Advanced menu. Occassionally Auto Select may assign sources incorrectly, which may be
corrected using the Advanced Source Selection. An example of this is where twin installations
with NMEA2000 compliant engines are not programmed with unique instance numbers. This
means that the auto select feature can’t determine which engine is  tted on the port and
which is  tted on the starboard side.
