Charts | NSO-II Operator Manual
Charts
The chart function displays your vessel’s position relative to land and other chart objects.
On the panel you can plan and navigate routes, place waypoints, overlay a radar image or
weather information, and display AIS targets.
The NSO-II has dierent embedded cartography depending on region. Units sold in
America will include Insight cartography, while units sold in other regions will have an
embedded basemap plus a cartography SD card. Depending on region, the cartography
options available are CMAP BDS or downloadable Navionics or CMAP for Europe. All units
will support Navionics Platinum Plus and TurboView via the SD Card slot on the NSO
Processor. Charts are shared over the network, so only one chart card per boat is required.
The rst part of this section describes common usage of the charts. Chart options depend
on type of cartography. For more details, see further ahead in this section.

Charts | NSO-II Operator Manual
Positioning the chart on the panel
Chart orientation
Several options are available for how the chart is rotated in the panel. The chart
orientation symbol in the panel’s upper right corner indicates the north direction.
North up Heading up Course up
North up
Displays the chart with the north direction upward. Corresponds to the usual orientation
of nautical charts.
Heading up
Displays the chart with the vessel’s heading directly up on the chart image. Heading
information is received from a compass. If heading is not available, then the COG from the
GPS will be used.
Course up
Rotates the chart in the direction of the next waypoint when in navigation mode. This
option works only when there’s an active route. If no route is active the heading up
orientation will be used until a route is made active.
Look ahead
This option centres the chart slightly forward of your vessel so that you can maximize your
view ahead.
Chart settings panel
Settings and display options made in the Chart settings page are common for all chart
panels.
For optional chart panel settings, refer the illustration on page 17.
3D boat selection
Determines which icon to use on 3D charts. See “Chart panel” on page 17.
Range Rings
Turns on/o range rings on the chart.
The range rings can be used to present the distance from your vessel to other chart
objects.
The range scale is set automatically by the system to suit the chart scale.
Vessels’ extension lines
Sets the length of the extension lines for your vessel and for
other vessels shown as AIS targets.
The length of the extension lines are either set as a xed
distance, or to indicate the distance the vessel will move in
the selected time period.
Own vessel heading is based on information from the active
heading sensor and COG from active GPS sensor.
For other vessels COG data is included in the message received from the AIS system.

for each chart panel.
If you have Navionics charts available in the SD card slot, you can show Navionics and
Insight charts simultaneously in a split screen.
¼Note: To show C-Map charts, you need to select Insight chart type in the menu.
If Insight chart is embedded and you have a C-MAP card in the slot or on the Ethernet
network, the system will automatically select the chart with most chart details for your
displayed region.
The same applies if you have two Navionics charts available.
Chart data
The NSO-II can use Navionics Platinum Plus and TurboView via SD Card Slot accessible
from the NSO Marine Processor box.
Charts are shared over the network, so only one chart card per boat is required.
¼Note: The system will not automatically switch to embedded cartography if the SD card
is removed. A low-resolution chart will be displayed until you re-insert the SD card or
manually switch back to embedded cartography.
