1-2 Using the G-PILOT 3100 with other instruments
1-2-1 Using other instruments
The G-PILOT 3100 can use data from these
instruments:
GPS: A GPS or chartplotter, such as a
Navman TRACKER 5000 series chartplotter
must be connected to the G-PILOT 3100 for
the G-PILOT 3100 to operate in GPS mode
(see the G-PILOT 3100 Operation Manual).
Note: GPS must be via NMEA input.
WIND: A wind instrument, such as a Navman
WIND 3100 series, must be connected to
the G-PILOT 3100 for the G-PILOT 3100 to
operate in WIND mode (see the G-PILOT
3100 Operation Manual).
SPEED: A speed instrument, such as:
Navman’s SPEED 3100 with a
paddlewheel speed sensor
or a GPS or chartplotter, such as
Navman’s TRACKER 5000 series
chartplotter can be connected to the
G-PILOT 3100 to increase steering
accuracy.
Note: The speed from a paddlewheel
sensor is the speed that the boat is moving
through the water. The speed from a GPS
is the speed over the ground. If there is a
water current then these two speeds will be
different. If the G-PILOT 3100 is connected
to an instrument with a paddlewheel sensor
and to a GPS, then the G-PILOT 3100 will
automatically use the speed from the
paddlewheel sensor instrument.
1-2-2 NavBus
NavBus is a Navman proprietary system that
allows systems of multiple instruments to be
built using a single set of transducers. When
instruments are connected by NavBus:
If you change the units, alarms or
calibration in one instrument, then the
values will automatically change in all
other instruments of the same type.
Each instrument can be assigned to a
group of instruments, called a backlight
group (see BKL GROUP in the FACTORY
menu, in the G-PILOT 3100 Operation
Manual). If you change the backlight in an
instrument in group 1, 2, 3 or 4 then the
backlight will automatically change in the
other instruments in the same group. If
you change the backlight in an instrument
in group 0 then no other instruments are
affected.
If an alarm sounds, mute it on any
instrument which can display that alarm.
For more information, refer to the NavBus
Installation and Operation Manual. Note: GPS
must be via NMEA input.
NavBus and the G-PILOT 3100
The G-PILOT 3100 will automatically
work with additional display units.
The G-PILOT 3100 can receive wind data
from Navman’s WIND 3100 over NavBus.
The G-PILOT 3100 can receive speed
data from Navman’s SPEED 3100 over
NavBus.
1-2-3 NMEA
NMEA is an industry standard, but is not as
fl exible as NavBus as it requires dedicated
connections between instruments. The G-
PILOT has one NMEA input port and one
port that can be configured to be an input
or an output (See G-PILOT 3100 Operation
Manual).
G-PILOT 3100 NMEA inputs
GPS: The G-PILOT 3100 can receive
NMEA GPS data from a compatible GPS or
chartplotter, such as Navman’s TRACKER 5000
series chartplotter:
XTE (from APA, APB or XTE sentences)
is required for the G-PILOT to use GPS
mode
BRG (from APA sentences) and BOD
(from APA or APB sentences) are optional
and improve performance
COG (from VTG sentences) is optional
and can be displayed.
WIND: The G-PILOT 3100 can receive NMEA
wind data from a compatible wind instrument:
True or apparent wind direction (from
MWV sentences) is required for the
G-PILOT to use Wind mode.
SPEED: The G-PILOT 3100 can receive NMEA
speed data from a compatible paddlewheel or
GPS instrument:
SOG (from VTG sentences) is optional
and improves performance.
Note: If the G-PILOT 3100 is connected to a
