1.2.1 Cable

The Weather Station instrument can be connected to a device and/or network in
several ways. You must have the correct cable before beginning the installation.
Additional cable lengths are available.

• NMEA 0183 10m cable (option)

• NMEA 2000® 6m cable

• NMEA 2000® 10m cable (option)

1.2.2 Antenna Mount

The Weather Station instrument has standard1-14" UNS threads. Attach the instru-
ment to a marine extension pole.

1.3 Choosi ng the Mounting Location

For accurate readings and a reliable GPS signal, selecting the best location for the
Weather Station instrument is very important. Easy access and appearance should
be secondary considerations. Since each installation is unique, the best separation
distances from other equipment on the boat will vary depending on the particular
equipment and how it is configured. Choose a location that balances the require­ments below (see the figure on the next page).

• The Weather Station instrument must be mounted in “clear air”—away from
obstructions in any direction that will interfere with air flowing through the unit. If
there is an obstruction, be sure to mount the Weather Station instrument at least
2m (6') away. On land, avoid roof tops, chimneys, trees, etc.

• If possible, mount the Weather Station instrument higher than any other object.
Mount it a minimum of 500mm (20") above the surrounding surfaces.
Note: The higher the Weather Station instrument is mounted, the less accurate
the pitch and roll readings.

• Because the Weather St ation instrument has an electronic compass, it should be
at least 0.30 m away from any on-board radar equipment or other strong mag­netic fields from equipment such as radio transmitters, boat engines, generators,
etc.

• Because the Weather Station instrument has a GPS, it must be lower than any
on-board INMARSAT communications antenna.

• Because the Weather S tation instrument has a GPS, be sure it is as far as possi­ble from high-powered transmitting antennas to avoid mutual interference.

• Because the Weather Station instrument has a GPS, check for any electromag­netic shading. That is, any obstructions from other vessels or shoreline buildings
that will interfere with the GPS signals that the Weather Station instrument must
receive.

1.4 Installing the Weather Station Instrument

Before beginning the installation, note the following points:

• The blue metal plate and the blue film found in the wind channel of the Weather
Station instrument are essential to its operation (see the figure below). Be care­ful not to scratch the plate, puncture the film, or damage them in any way.

• Do not remove the waterproof connector(s) to ease cable routing. If the cable
must be cut and spliced use a suitable splash-proof junction box. Cutting the
cable or removing the waterproof connector(s), except when using a junction
box, will void the sensor warranty.

• The Weather Station instrument must be installed vertically—NOT tilted to one
side.

Installation overview

1. Fasten the marine extension pole (local supply) to the chosen location. Be sure

the pole is vertical.

2. Screw the bottom of the nut assembly onto the marine extension pole.

Hand-tighten only. Do not over tighten.

3. With the nut assembly on the cable near the Weather Station connector , thread

the cable through the pipe. Be sure to leave several inches of cable extending
beyond the nut assembly.

CAUTION: If you use a thread lock, use plumber’s tape. Do not use a liquid
thread lock as it may weaken the plastic, causing it to swell and crack.

4. Screw the nut assembly onto the top of the pipe. Hand-tighten only. Do not

over tighten.

5. Remove the warning label from the Weather Station instrument’s socket. (The

label may be discarded.) Remove the protective cover from the connector.
(Save the cap to protect the connector, when the W eather Station instrument is
removed.) Plug the 9-pin connector into the Weather Station instrument. The
alignment key on the connector fits into a notch in the base of the Weather Sta­tion instrument.

CAUTION: Be sure the alignment tabs on the Weather St ation instrument point
forward toward the bow and parallel to the centerline of the boat. This is neces­sary to accurately measure wind direction and vessel heading.

6. Be sure the alignment tabs on the Weather Station instrument are facing for-

ward and parallel to the keel (centerline) of the boat (see the figure on previous
page). Slide the captive nut upward and screw it onto the base of the Weather
Station instrument (see the figure on previous page). Hand-tighten only. Do
not over tighten. Be careful NOT to rotate the Weather Station instrument or
loosen the nut assembly from the antenna mount. Double check to be sure the
alignment tabs are still facing forward.

Do not hand tighten or align the Weather Station instrument by holding
the upper cap. Grasp the unit by hand below the wind channel to tighten
and align.

4. HOW THE WEATHER STATION

INSTRUMENT WORKS

About the Ultrasonic Wind Sensor

The ultrasonic wind sensor (an ultrasonic anemometer) measures apparent wind
speed and direction. The Weather Station instrument contains four ultrasonic
transducers, visible through the four holes in the top of the sensor’s wind channel
(see the figure below). These transducers operate in pairs—one transducer injects
a pulse into the air, and the other (directly opposite to it) listens for the arrival of that
pulse. Each pulse bounces off the metal plate at the bottom of the wind channel
and is carried by the wind to arrive at the opposing transducer a short time later.

Weather Station ultrasonic wind sensor

When there is no wind, the pulse travels at the speed of sound from the sender to
the receiver. Whenever the wind is blowing, the pulse will arrive sooner than if the
air is still. Similarly, whenever the wind is blowing in the opposite direction, the
pulse will arrive later than if the air is still. The four transducers take turns in sending
and receiving pulses to cover all eventualities of wind direction.

A microprocessor within the Weather Station instrument then combines the mea­surements from all four transducers to calculate the resultant wind speed and di­rection. Throughout this process, the sensor monitors the air temperature, to
compensate for the fact that the speed of sound in air changes with temperature.

Note: Do not use wind data in the WIND mode of an autopilot, because the data is
not sufficiently accurate.

True and Apparent Wind

The Weather Station instrument has the unique ability to display both true and ap­parent wind. True wind is the actual motion of the air relative to the earth. Apparent

wind is the wind which an observer experiences while moving or on board a boat.
It is the result of two motions—the actual motion of the air (the true wind) and the
motion of the boat. If the vessel is not moving, then the true and apparent wind will
be the same.

Wind channel

There are two components to any wind measurement: speed and direction. By con­vention, the wind direction is an angle representing the direction from which the
wind is blowing. Sometimes this angle is referenced to true or magnetic north, and
sometimes it is referenced to the bow of the vessel. Both true and apparent wind
use these same references.

Consider the case of a vessel proceeding at a speed of 15 knots in calm air. An
observer on board would experience a wind of 15 knots from dead ahead. This ap-
parent wind would be due solely to the motion of the boat. If a true wind of 15 knots
was blowing from the stern, an observer would experience dead calm—no appar-
ent wind. That is because the boat is moving at the same speed and in the same
direction as the surrounding air.

Now, consider the more complicated situ­ation of a vessel proceeding at 15 knots
with a true wind of 15 knots blowing from
the side (see the figure at right). To an ob­server on board, the apparent wind would
be 21.2 knots blowing from an angle 45º
off the bow.

In order to calculate the true wind speed
and direction when on board a moving

vessel, it is necessary to know the appar­ent wind speed and direction, the speed and course over ground of the vessel, the
compass heading, and the local magnetic variation. Note that heading and course
are not the same thing: heading is the direction the bow of the vessel is pointing,
while course is the direction the vessel is traveling. Heading and course may differ
due to the effects of wind and current.

Because true wind is calculated using the data from several sensors, its accuracy
depends on the accuracy of all the raw data used in the calculation. For instance,
if the electronic compass is located near iron or a similar magnetic disturbance, the
heading will be incorrect, and the true wind calculation will therefore be in error,
perhaps by quite a bit. In another example, the speed and course over ground pro­vided by the GPS receiver are averaged over time. If the boat is performing ma­neuvers, changing speed and/or direction, then it will take a few seconds for the
SOG and COG values to "catch up". The reported true wind values will therefore
also be incorrect until the vessel reaches a steady-state condition, traveling in a
straight line at a constant speed.

Air Temperature Sensor

The Weather Station instrument includes a built-in negative-temperature-coeffi­cient thermistor that measures the ambient air temperature. This NTC thermistor is
located in a thermally isolated region of the Weather Station housing that is open
to the outside air.

Wind Chill Temperature

Wind Chill is a term that describes the heat loss on the human body resulting from
the combined effects of low temperature and wind. As wind speed increases, heat
is carried away from the body at a faster rate, causing a reduction in skin temper­ature. Because the face is the part of the human body that is most likely to be ex­posed, the wind-chill index is adjusted for the average adult face.

The concept of wind chill does not apply to inanimate objects, such as a boat. The
only effect that wind chill has in this case is to shorten the time it takes the object
to cool to the actual air temperature––wind chill does not cause an object to cool
below that temperature. For example, fresh water freezes at 0°C (32°F) regardless
of what the wind chill is.

The Weather Station instrument calculates two values for wind-chill temperature:
one using the apparent wind-speed, and one using the true wind-speed. The ap-
parent wind-chill temperature is relevant to what an observer is currently experi­encing on the vessel. The true wind-chill temperature indicates what the wind chill
would be if the vessel were not moving.

Wind chill temperature is only defined for temperatures at or below 10°C (50°F)
and wind speeds above 2.6 knots (3MPH).

In the default condition, transmission of wind-chill data is disabled or enabled de­pending on NMEA format used.

Barometric Pressure Sensor

The Weather Station instrument contains a temperature-compensated, silicon, pi­ezoresistive, pressure sensor. It measures atmospheric pressure for use as a dig­ital barometer. While a single measurement of air pressure at a given location has
little value, the trend of changing pressure and wind over time can be a useful tool
in performing basic weather forecasting.

GPS

This Weather Station instruments has a built-in Global Positioning System with its
own antenna, receiver, and position determining electronics. The GPS receiver re­ceives radio signals from a constellation of orbiting satellites maintained by the
U.S. government. By accurately measuring the time it takes for a transmission to
travel from each satellite to the receiver, the unit is able to determine the distance
between the satellite and the receiver. When the distance is known to three satel­lites, the unit is able to calculate the latitude and longitude of the receiver. This is
known as a 2D fix. If the distance is known to four or more satellites, then the unit
is additionally able to calculate the altitude of the receiver. This is known as a 3D
fix.

16

The GPS receiver in the Weather Station instrument takes approximately one
minute on average to achieve a position fix after power is first applied. This is
known as the "time to first fix."

The GPS receiver synchronizes itself to the atomic clocks on board each satellite.
This allows the GPS receiver to accurately determine the date and time as well.

If the GPS receiver is mounted on a moving vessel, its changing position over time
allows the speed and course over ground to be calculated. The course reported by
a GPS is always with respect to true north.

The ability of the Weather Station instrument to calculate true wind speed and di­rection depends on the presence of a GPS fix. If the GPS receiver is not tracking
at least three satellites, then the Weather Station instrument will be unable to pro­vide true wind data. (Apparent wind data should always be available, regardless of
the status of the GPS receiver.)

True Wind Relative to Water

If a fix from a GPS receiver is not available, it is still possible for the Weather Station
instrument to determine a value for true wind, if the speed of the vessel through the
water is known. In this case, it is necessary that a water-speed sensor with an
NMEA output be connected to the NMEA input on the Weather Station instrument.

The Weather Station instrument's calculation for true wind relative to water makes
the significant simplifying assumption that the vessel's course is the same as its
heading. That is, the effects of wind and current on the motion of the boat are ig­nored. The direction of the true wind relative to water is referenced only to the bow
of the vessel, not to true or magnetic north.
