Software setup | NSO evo2 Installation Manual
Devices with the Group set to None can be set to use diff erent sources to those of the rest of
the network devices.
Advanced source selection
This allows the most fl exible and precise manual control over which devices provide data.
Some data sources, such as those for fuel level, or engine RPM, can only be changed via the
Advanced menu. Occassionally Auto Select may not assign the desired source, which may be
corrected using the Advanced source selection. An example of this is where twin installations
of NMEA 2000 compliant engines are not programmed with unique instance numbers. This
means that the auto select feature can’t determine which engine is fi tted on the port and
which is fi tted on the starboard side.
¼ Note: the Advanced option is visible in multiple places - the bottom of the Sources list, and
under each source category (eg Compass). The latter shows a fi ltered list that only relates to
devices that output data relevant to the category.
Device list
The device list shows the physical and virtual devices that provide data. This may include a
module inside the NSO evo2, the NMEA 0183 port, or any external NMEA 2000 device.
Selecting a device in this list will bring up additional details and actions:
All devices allow allocation of an instance number via the Con gure option. Set unique
instance numbers on any identical devices on the network. The Data option shows all data
being output by the device. Some devices will show additional option(s) specifi c to the
device - the RC42 illustrated above has a Calibration option, to allow easy setup of this
device which does not have it’s own user interface.
SimNet Groups
It is possible to group certain settings so they are duplicated across the network on multiple
displays. Display (ie backlighting), Units (ie metric, imperial), Damping (to dynamic data),
and Alarms can be grouped either in ‘Simrad’ group, or groups ‘1’ through to ‘6’. If any of the
settings require discrete control, set it to ‘none’.
Diagnostics
The NMEA 2000 tab on the diagnostics page can provide information useful for identifying an
issue with the network.
Bus state: This simply indicates whether the bus is powered, but not necessarily connected
