Northstar Explorer 538i/538 Installation and Operation Manual 55
During setup to send NMEA data to other
instruments, set NMEA out to and specify
the NMEA data to send (see section 14-9).
Setup and test
1 Put a blanking cap on any unused connector
on the back of the display unit. Ensure all
connectors are plugged in and the display
unit is in place.
2 If the display unit is bracket mounted, adjust
tilt and rotation for best viewing and hand
tighten the knob.
3 Insert any required C-MAP chart card (see
section 1-3).
4 Turn the instrument on (see section 2-3).
When the Explorer 538/538i is turned on for
the first time, it displays an installation menu:
i Select the language to use.
ii Change the data if necessary (see section
2-1)
iii When the setup data is correct, press
.
This data can be changed later (see section 14).
NMEA is an industry standard for interconnecting
instruments. It is not as flexible or as easy to install
as NavBus. The Explorer 538/538i 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 14-9).
For information on sending NMEA data to the
Explorer, see your Northstar dealer.

5 Enter setup data to set up the Explorer
538/538i to your requirements and to set
up any optional sensors or instruments (see
section 14).
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.
