SECTION 2
Using the NMEA masthead sensor independently to the Meteoman.
(This procedure is not necessary when using the sensor with
the Meteoman).
Mount the sensor as described in the installation instructions. Connect
the screen wire to the negative supply and the red wire to 12 volt
positive supply. The NMEA output is on the blue wire. The output
format is NMEA 0183 and the NMEA sentences MWV and XDR.
To calibrate the wind vane heading :- align the wind vane towards the
bow of the vessel. (or North in a fixed installation).
1 - Disconnect the 12 volt power supply.
2 - Link the NMEA output (blue wire) to supply negative
3 - Connect the 12 volt power supply.
4 - Remove the link between the NMEA output and negative. The display
will now show bow (or north) up on the display.
SECTION 3
Questions & Answers
Q This Display is completely blank.
A Check the power supply. It should be 12 volts with the centre pin of
the power supply connector positive. Check the 1 amp fuse in the
power lead.
Q When calibrating the pressure, how do i know what the local
pressure is?
A Choose a day when there are few isobars (ie. the local pressure is fairly
uniform over wide areas), and set the unit to read the day's pressure
at sea level which is published widely, such as at the UK National
Physical Laboratory. web: www.npl.co.uk/pressure/pressure.html.
