2. Variation value from a different source:
• If heading data is being taken from NMEA, but no NMEA variation is
available, then variation is taken from SeaTalk
• If heading is taken from SeaTalk, but no SeaTalk variation is available,
then variation is taken from NMEA
3. A calculated variation value, using position data, if no SeaTalk or NMEA
value is available
4. The current manual variation value, if no SeaTalk or NMEA value and no
position data is available
Manual Mode
If you select Manual mode, by pressing either of the
MANUAL
keys, you can
specify the local variation value according to the area in which you are
operating. Press the appropriate
MANUAL
key to adjust the variation up or
down, to a maximum of 30° East or West.
This value is then transmitted to any other SeaTalk instruments on your
system. It is retained if you turn the display off and on again.
In Manual mode, incoming NMEA variation is ignored. However, if the
variation is changed on another SeaTalk instrument, the new value is used and
the manual value that is displayed is updated.
Note: The Manual variation value defaults to 0°, so it is important to set up a
value if variation is not available from an external source.
Bridge NMEA Heading
The HSB Series displays bridge NMEA input data to the SeaTalk bus (see
Section 8.8 ).
The Bridge NMEA Heading option can be used to prevent NMEA heading
data being bridged onto the SeaTalk bus.
For example, if you have a course computer connected on SeaTalk and
NMEA, and an active compass connected on NMEA (for MARPA), SeaTalk
data overrides NMEA data in the course computer. You should therefore
switch
OFF
the Bridge NMEA Heading option to ensure the course computer
receives the same NMEA heading input as the radar system.
Cursor Echo
You can set up an integrated system so that radar and chartplotter displays
connected via SeaTalk can display each other’s cursors.
Cursor echo functions so that you can display a chart cursor on the radar
picture, or a radar cursor on the chart picture (you cannot display a remote
