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.

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 557/567 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)

This data can be changed later
(see section 15).
5
Enter setup data to set up the 557/567 to
your requirements and to set up any optional
sensors or instruments (see section 15).
6
At the satellite window, 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).

Go on a test run to check that the navigation
equipment works correctly, particularly when
a radio trans mitter or radar is used.
16-10 Installation: Setup and test
NMEA is an industry standard for interconnecting
instruments. It is not as flexible or as easy to install
as NavBus. The 557/567 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 15-10).
Receive data from an optional AIS receiver.
For information on sending NMEA data to the
557/567, see your Northstar dealer.
During setup to send NMEA data to other
instruments, set
NMEA out
to
and specify
the
NMEA data
to send (see section 15-10).
