Navigation Panel
This panel allows the operator to set the various aspects of the navigation system.
The upper section of the panel displays the navigation status of the external device
interfaced to the GPS terminals of the sonar allowing the operator to easily determine
which NMEA sentences contain valid information.
The operator selects the most accurate NMEA sentence available for heading, speed and
latitude/longitude system information. Interfacing to a Satellite Compass is
recommended.
Net height adjustment, Wake Trail/Range Ring color and minimum speed to be used
by
the system are also available.
Navigation Status
The current status of the navigation system is also
reflected in the HD (heading), Spd (speed) and L/L
(latitude/longitude) menu item selection text.
Selections presented in the green color indicate a valid
choice while selections presented in red were not
found to be present in the navigation data and
therefore should not be used.

In this example the RMC, VTG, GLL and GGA
indicators at left (highlight color) are recognized
by the system. Valid HD (heading), Spd (speed)
and L/L (latitude/longitude) data packets were
located for each sentence as
demonstrated by
the green text to the right of
the header.
NMEA headers shown at left (in red text)
terminated by a NULL character (Ø) were not
found by the system in the incoming navigation
data.
