3.4 DISPLAY MENU
To allow you to change how the chart plotter displays information. It is possible to
select this menu only from the Chart Display page or the Depth Graph page in
split mode.
[MENU] + [MENU] + "DISPLAY" + [ENTER]
Auto Info : Allows displaying information on cartographic object when the cursor is placed on it. The
Automatic Info On Points shows information when the cursor is placed on points (as Port
Services, Tides, lights, wrecks, rocks, buoys, beacons, obstructions, land markers, etc.). The
Automatic Info On All shows information when the cursor is placed on points, on lines (as Depth
contours, Traffic Separation, Territorial Sea, Cartographic Lines etc.) on areas (Depth, Built-up,
Sea, Attention, Restricted etc.) and on names (on the beginning of the text -hot spot- or on any
of the characters of the name -name message box-). The details on Land, Source of Data,
Cartographic Area and Spot Soundings are not shown.
Look Ahead : In Home mode the Look Ahead function sets up the charts on the navigation direction (course)
in order to display more map details in front of the vessel’s position.
Course Line : Selects the value among Off/2/10/30 Min/1/2 hours/Infinite. The Course Line is a graphical
indication of the direction in which the Vessel is heading. The Course Line origin is the vessel’s
position so the time line movement is synchronized with the vessels Icon. Course Line "course"
is given by the value of COG (Course Over Ground) and its length is proportional to the SOG
(Speed Over Ground).
Coordinates System: If TD is selected as Coordinate System, a new menu appears on the screen to set Chain, Pair,
ASF 1/2, Alternate Solution.
Map Datum : Allows selecting any Geodetic Datum reference from the over 100 available on the chart plotter.
Map Datum selection switches to the selected reference datum applying the datum offsets
stored with the charts.
Fix Datum : Sets the datum reference used by the GPS receiver connected to (or integrated in) the chart
plotter so that the chart plotter converts the position received from the GPS to the Map Datum
currently selected in the menu in order to match the position from the GPS with the position on
the charts. You must know what datum reference is used by the GPS and set it in the Fix Datum
option.
External WPT : The coordinates of a Waypoint, received from a GPS connected to the chart plotter, can be
stored into the chart plotter, if the GPS is NMEA-0183 protocol compatible and support the
$BWC sentence (this symbol remains on the screen for 30 seconds). You may save it by placing
a Waypoint or a Mark onto that symbol. As soon as the chart plotter receives another $BWC
sentence with the coordinates of a new Waypoint, the symbol moves to the new point.
User Points : Sets On (icon + label), Off or Icon (only icon) the displaying of User Point.
Data Window Mode : Customizes the Text Area layout between OFF and Text Area with a variable number of boxes.
Cursor Window
