The chart is re-drawn at its previous scale and the MOB symbol and data box
are removed.
Note: The MOB procedure can also be initiated or cancelled if the appropri-
ate SeaTalk message is received by the display unit.
8.5 Cursor Echo
In a system with a radar display connected via SeaTalk, you can set the display
to enable cursor echo. Cursor echo (accessed from System Set Up, described
in
Section 4.3 ) enables you to display a radar cursor on the chart picture, or a
chart cursor on the radar picture (you cannot display a remote chart cursor in a
chart window nor a remote radar cursor in a radar window).
The following options can be toggled
ON
or
OFF
:
• Radar Cursor In: displays the cursor from another radar on the chart dis-
play or chart window (default -
OFF
).
• Chart Cursor In: displays the cursor from another or chartplotter on the
radar display or radar window (default -
OFF
).
Note: The remote display must have SeaTalk Cursor Out enabled.
• SeaTalk Cursor Out: enables the output, onto SeaTalk, of the display’s
own cursor (default -
OFF
).
• Cursor Echo Local: echoes the cursor position between open windows on
the same display (default -
ON
).
If you set the options to
OFF
, no cursor echo information is displayed.
When the appropriate option is switched on, the display shows its own cursor,
plus the cursor of the other display with appropriate cursor text (
RDR
or
CHT
) to
indicate its origin. This means that you could move the cursor over a target on
the radar display and check the identity of the target by looking at the radar
cursor position on the chartplotter.
8.6 Radar Overlay
If radar data is available from another display connected on
hsb
2
, the radar
targets can be overlaid onto the full-screen chartplotter display. The radar/
chart overlay option helps you to distinguish between fixed, charted objects
and other objects that could be moving vessels. Some radar controls are
available in overlay mode.
The following criteria must be true for radar/chart overlay to function
correctly:
