Installation and Operation Manual

20-11 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 Instrument 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 19-12).

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 2-2).

When the Instrument 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

ESC

This data can be changed later
(see section 19).

20-12 Installation: Setup and test

5 Enter setup data to set up the Instrument

to your requirements and to set up any
optional sensors or instruments (see section
19).

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 8).

7 Go on a test run to check that the navigation

equipment works correctly, particularly
when a radio trans mitter or radar is used.

For information on sending NMEA data to the
Instrument, 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 19-12).
