NAVMAN
G-PILOT 3380 Operation Manual
6-7
Setup > Comms
Use this feature when the G-PILOT is connected
to other Navman instruments through NavBus
or any compatible NMEA instrument.
NMEA mode
Select NMEA port mode.
Input
– NMEA port can receive NMEA data
Slow
– NMEA port outputs heading and
rudder angle once per second
Fast
– NMEA port outputs heading data ten
times per second
NavBus group
Use this when a group of Navman
instruments are connected together using
NavBus, to specify a group of instruments
for backlighting, if required. Then, if the
backlight setting on one instrument in the
group is adjusted, the other instruments
change automatically. Otherwise, select 0.
6-8
Setup > Calibrate
The calibrate wizard screens are used during
the initial G-PILOT installation stage or if any
previously installed G-PILOT transducers have
changed or moved.
It is vital to the performance of the G-PILOT
that the transducers are installed in the best
location and carefully calibrated.
Compass
Use this calibration wizard to calibrate the
compass.
Follow the on-screen instructions:
• Slowly turn boat 2.5 times, observing
the turn rate indicator
• Align heading – press
and dial in
the current heading
• Accept calibration
• Calibration complete
Rudder
Use this calibration wizard to calibrate the
rudder.
Follow the on-screen instructions:
• Center the rudder
• Turn rudder to Maximum Port
• Turn rudder to Maximum Starboard
• Set angle – press
and dial in the
current rudder angle
• Center the rudder
• Stand clear of the rudder and linkages
so the G-PILOT can test the limits.
• Testing limits – press
at any time
to abort the calibration
• Accept calibration
• Calibration complete
Align heading
Use to align the compass to the actual boat
heading. If a compass calibration has recently
been performed, it is not necessary to align the
heading again.
Use the manual helm to sail a straight course
and ensure the boat heading does not change
during this procedure. Use an accurate
reference compass or external GPS to find
the actual boat heading. If you are using an
external GPS, sail as fast as convenient to
ensure the heading is accurate.
Enter the actual course heading.
Minimum = 0°; maximum = 359° (degrees)
Center Rudder
Use to set the rudder center position. If
a rudder calibration has recently been
performed, it is not necessary to set the rudder
centre position again. Ensure the rudder is
in the center position and that there is no
cross-wind or tidal current affecting the rudder.
Select OK and press
when the rudder is
centered.

Setup > Simulate
Turn simulate mode on and off
(see section 3-14).
