18-11 Installation: Other NMEA instruments
NMEA is an industry standard for interconnecting
instruments. It is not as flexible or as easy to
install as NavBus.
The Explorer can:
Receive and display wind speed and
direction from an optional compatible wind
instrument.
Receive and display depth, paddlewheel
boat speed and water temperature from an
optional compatible instrument.
Receive data from an optional compatible
GPS or GPS/DGPS source.
Send GPS position and other navigation
data to an autopilot or other instrument.
An autopilot requires APB, APA and VTG
sentences (see section 17-10).
For information on sending NMEA data to the
Explorer, see your Northstar dealer.
During setup to send NMEA data to other
instruments, set
NMEA out
to
and specify
the

18-12 Installation: Setup and test
5
Enter setup data to set up the Explorer to
your requirements and to set up any optional
sensors or instruments (see section 17).
6
At the satellite display, check that it picks
up GPS satellites. Wait for the GPS receiver
to start up and the fix type to change from
‘Acquiring’ to ‘GPS fix’. This should take less
than two minutes (see section 7).
7
Go on a test run to check that the navigation
equipment works correctly, particularly when
a radio trans mitter or radar is used.
