Setup > Comms (443Df Only); Setup > Calibrate - NorthStar EXPLORER 443D Installation And Operation Manual

Fuel
Select from:
• Litres
• USGal (US gallons)
• ImpGal (Imperial Gallons)
3-7 Setup > Comms
Use this feature when the Explorer 443d/443df
is connected to other Northstar instruments
through NavBus or any compatible NMEA
instrument.
Press MENU once or more until the Setup menu
is displayed, then select Comms:
NMEA Out
NMEA is generally used with third party
instruments. Select to transmit NMEA
sentences (see Appendix A - Specifications).
3-8 Setup > Calibrate
Press MENU once or more until the Setup menu
is displayed, then select Calibrate:
Speed*
Calibration may be required because different
hull shapes have different flow characteristics.
Obtain an accurate measurement of the boat's
speed from a GPS receiver; or by following
another boat travelling at a known speed; or by
making a timed run over a known distance.
Temperature
Select either:
• °F (Fahrenheit)
• °C (Celsius)
(443df only)
The fuel options
can be calibrated
only when the
optional single
or twin engine
kit is installed on
petrol/gasoline
engines.

NMEA data
Use this to specify which NMEA sentences will be
transmitted (see Appendix A - Specifications and
section 5-7 Data display, for information about
how to display NMEA data).
NavBus
NavBus is the preferred method for connecting
the Explorer 443df to other Northstar
instruments. Select if the instruments are
connected using NavBus.
NavBus Group
Use this when a group of Northstar instruments
are connected together using NavBus, to specify
a group of instruments for backlighting, if
required. Then, if the backlight setting on one
instrument in the group is adjusted, the other
instruments change automatically. Otherwise,
select 0.
Note: for accurate calibration:
The speed from a GPS receiver should be
•
greater than 5 knots.
The speed from another paddlewheel
•
transducer should be between 5 and 20
knots.
Best results are achieved in calm conditions
•
where there is minimal current (best at high
or low tide).
Use the cursor keys to display the speed readout
box, then increase or decrease the readout to
match the independent speed value.
Speed Filter*
Increase this setting to stabilise an erratic
speed reading. Decrease to improve reading
responsiveness. The speed filter can be set from
0 to 30 seconds.
