ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent damage to
electronic circuits. The Magellan is adequately protected against ESD for
its intended use. However, it is possible to damage the product by
delivering electrostatic discharges when touching, removing, or inserting
any objects inside the equipment housing.
To avoid delivering high static voltages yourself:
1. Handle ESD sensitive components on a properly grounded and
protected ESD workbench. When this is not possible, ground
yourself with a wrist strap and a resistive connection cord to the
equipment chassis before touching the boards. When neither of
the above is possible, at least touch a conductive part of the
equipment chassis with your other hand before touching the
boards.
2. Always hold the boards by the edges and avoid touching the
component contacts.

Principles of Measurements
Temperature
The temperature sensor in the Magellan uses a precision triple-element
thermistor. This provides highly accurate and stable temperature
readings.
Humidity
The relative humidity sensor is a capacitive polymer sensor. The
construction of the humidity sensor element provides excellent
resistance to wetting, dust, dirt, oils, and common environmental
chemicals.
Barometric Pressure
The barometric pressure sensor is a stable transducer using nanotechnology, yielding a linear and repeatable sensor with low hysteresis.
The piezoresistive pressure sensor module is mounted on a small
electronic circuit board.
A microcontroller controls the operation of the sensor and the data
interface. The microcontroller polls the pressure sensor module once per
second for the barometric pressure and ambient temperature. The raw
readings are temperature corrected by the microcontroller.
Wind Measurement
A unique folded-path, low-power sonic anemometer operates on the
principle that the speed of the wind affects the time it takes for sound to
travel from one point to a second point. If the sound is traveling in the
direction of the wind, then the transit time is decreased. If the sound is
traveling in a direction opposite the wind, then the transit time is
increased.
Fluxgate Compass
The internal compass module is low power and compact. It employs a
pair of magneto-inductive sensors which change inductance with varying
magnetic field strengths, to sense the Earth’s magnetic field.
The microprocessor measures the output of the internal compass and
then corrects wind direction data for the orientation of the sensor. The
output of the wind direction is relative to magnetic North. A user
programmable value of Magnetic Declination may be entered through
terminal mode to enable output relative to True North rather than
Magnetic North.

________________________________________________________________________
Installing the Mast
There are three acceptable methods for mounting the mast to a roof or
building structure: Sloped roof mounting, flat roof mounting or wall
mounting. See Optional Sensor Mounting Hardware for more
information.
Location
Do not attach the sensor transmitter to a radio transmitting mast or
tower.
Select a mounting location that will allow the sensor cable to be routed
away from other data cables to avoid interference. Do not mount sensors
close to power lines. For normal roof mounting, the recommended
minimum distance from power lines is 25 ft. (8 m). Use extreme caution
when working close to power lines.
Mounting Method
Choose the appropriate mounting method for the installation and obtain
any necessary mounting hardware. Refer to Optional Sensor Mounting
Hardware section for information on optional sensor mounting hardware
and accessories which are available from the factory.
If the mounting hardware is not obtained from the factory, be certain to
use metal parts which are plated or galvanized to assure maximum
longevity.
Secure the mast to the roof, using guy wires with sufficient tensile
strength or to building wall using a wall-mount hardware kit.
Routing Cable
Use plastic tie wraps to secure the cable to mast, particularly at the mast
base. Tighten the tie wraps securely and clip off any excess length with a
wire cutter tool.
Once the Magellan sensor transmitter has been installed route the cable
back to the Interface Module or weatherproof enclosure.
CAUTION: There may be electric wires in the wall. When routing cable
through walls, we recommend that you shut off the electricity in the
room(s) where you are drilling.
Any mast or tower should always be properly earth grounded to minimize
electrical storm damage. The use of a properly grounded metal mast or
tower, however, does not insure protection from electrostatic discharge.
These items could become electrically charged resulting in damage to
the sensors and/or console. This could damage the system in the event
of an electrical storm.
Columbia Weather Systems, Inc.
26
Magellan Weather Station
________________________________________________________________________
Note: If the standard 50 ft. cable provided with the sensor transmitter is
not long enough, it may be extended by splicing on an appropriate length
of 22-gauge, stranded, seven conductor shielded cable with the same
color code. When cutting and splicing, insure good contacts, proper color
coding of the terminal leads, and a good seal. (A good solder splice, and
water proof insulation are essential; merely twisting the respective wires
together is not adequate.) Additional cable (Catalog No. 81547) is
available from the factory.
Columbia Weather Systems, Inc.
Magellan Weather Station
27
________________________________________________________________________
Installing the Magellan Sensor Transmitter
Site Selection:
Finding a suitable site for the sensor transmitter is important in obtaining
representative ambient measurements.
The sensor transmitter should be installed in a location that is free from
turbulence caused by nearby objects, such as trees or buildings.
WARNING: To protect personnel (and the device), a lightning rod should
be installed with the tip at least 40 inches (one meter) above the sensor
transmitter. The rod must be properly grounded, compliant with all local
applicable safety regulations.
North Alignment
The Magellan sensor has a built-in electronic compass for North
alignment.
The Magnetic Declination has been entered into the sensor for your
area. To change the magnetic declination, please see the Operation

________________________________________________________________________
Installing the telescoping mast and
vehicle-mount brackets
1. Select a location on the vehicle where the Magellan sensor mast will
be installed.
2. Three mounting brackets are included with the mast. The mounting
base plate and a spring-loaded securing mounting bracket will be
permanently mounted to the vehicle for quick and easy set up. The
third bracket is attached to the mast and mates with a slot on the
spring-loaded mounting bracket. This bracket may be loosened and
re-positioned on the mast to fit the installation scheme and mounting
bracket positioning. A spacer for the spring-loaded bracket is
provided to insure that the mast is 90° vertical.
3. Ensure the vehicle-mount sensor connector is in close proximity to
the mast’s mounting bracket location (refer to the vehicle-mount
sensor connector section below). Mark and drill the appropriate
mounting bracket holes. Be sure to allow for sufficient structural
backing, to adequately support the mast and sensor.
4. External sensor cabling is intended to hang freely along the side of
the mast. This assures the mast’s easy extension and retraction
without pinching, crimping, or cutting the sensor cable. Users may
tie-wrap the cable to the lower portion of the mast. The external
sensor cable has a male connector that couples to the vehicle-mount

Set Up Instructions
Site Selection:
1. Upon arrival at the deployment site, determine a suitable location
where the Magellan mast may be set up away from physical
obstructions and heavy foot traffic. Because of the wireless
transceivers, the telescoping tripod and sensors may be located
as far as 1-mile (Line of Sight - LOS) away from where the
weather data is viewed.
2. Site location should be away from trees, buildings or other
obstructions that will alter accurate wind direction and speedreadings.
3. Screw the grounding/tie-down auger into the ground at the
center of the placement until the auger portion is adequately
secured.
4. If the site selection is on blacktop/pavement, use a 6” nail spike
or Rebar driven into the surface at a 45° angle. This sufficiently
secures the mast during operations.
Mast Set Up and Sensor Alignment:
1. Remove tripod components from the bag. Stand the tripod up
(without legs) so the sensor head may be attached to the mast.
2. Attach the Sensor Head to the mast.
3. Attach sensor cable by connecting the 8-pin waterproof male
connector/sensor cable to the one-foot female sensor pig-tail
waterproof connector.
4. Holding the tripod vertical, place tripod legs in their respective
slots, one leg at a time. Once the first leg is in, balance the tripod
until the other legs are inserted and the tripod is free standing.
5. With all legs in place, insert the leg locking pins. The tripod may
now be picked up and moved over the grounding stake.
6. Secure the tripod to the grounding stake using the clamp strap.
Ensure the strap is tight enough to keep the tripod in-place
during high winds.
7. Extend the mast to its fullest height and insert the locking pin.
8. If the guy wire kit is used, remove the sensor and mounting
adapter prior to mast set up and slide the guy wire ring collar
onto the mast extension, then reinstall the sensor. Anchor the
end of each guy wire to the corresponding tripod foot using the
wing nuts. Extend the mast fully and adjust the guy wires using
the turnbuckles to tighten the guy wires evenly.

________________________________________________________________________
Transportation Case and Sensor Plug-In
1. Place the Magellan transportation case at the foot of the tripod.
2. Attach the 8-inch wireless antenna to the antenna cable on the
outside of the case.
3. Plug the 8-pin Female Sensor Cable to the 8-pin male connector
on the outside of the case.
4. Ensure the red/black power cord connectors are connected to
their respective battery terminals inside the case.
5. Latch and seal the case to the internal components from the
weather elements.
Battery Power System
1. The Magellan comes with a Battery Power System that consists
of two 12VDC, 7.5AH batteries and a 12-Volt battery charger.
One battery will continuously operate the Magellan for
approximately 60 hours. One battery is intended to be charging
while the other is in operation.
2. Swap batteries, as necessary to continue weather station
operations.
Operation
Once the Mast is set up, with the Sensor Head attached, plug the
red/black power terminals to the corresponding battery terminals. The
Magellan will automatically sense and transmit weather data via wireless
transceiver.
1. Transceiver Power/Connectivity/Transmission:
a) Check for the red power light
b) Check for the steady green connectivity light
c) Check for the one-second green pulsing/blinking
transmission light
2. Once the transceiver lights are all operational, data is being
transmitted. If the green transmission light is not blinking once
per second, data is not being transmitted. Re-check the RS-232,
power, and antenna connections.
Monitoring
The data transmitted from the remote sensor can be monitored using the
Weather Display console, computer weather software, and/or Weather
MicroServer.
Connect the wireless transceiver to the appropriate device. Please refer
to the system diagrams provided with the system.

second period.
Successful entry into terminal mode will return the prompt:
Command (HE for Help, QU to Quit):
Magnetic Declination
The flux compass in the Magellan sensor provides wind direction to
Magnetic North. The sensor firmware allows the setting of a declination
angle to correct the wind direction output to True North. Once the
declination angle is set in the sensor, it is stored permanently in nonvolatile memory. The declination angle must be reset only if the system
is used in a different geographical location separated by many miles from
the original location.
Please note that the magnetic declination is set at the factory per
system, based on the shipping destination.
To reset the magnetic declination:
1. Determine the Correct Declination
Visit the following web site for help in determining the correct declination
for your site:
http://www.ngdc.noaa.gov/geomag/declination.shtml
Under Declination click “Calculate”
Under Lookup Latitude/ Longitude enter your zip code and click “Get &
Add Lat / Lon” or manually enter latitude and longitude.
Columbia Weather Systems, Inc.
56
Magellan Weather Station
________________________________________________________________________
Under Calculate Declination click “Calculate”
The declination will be displayed in degrees (º) and minutes ('), e.g. 16º
27'. Divide the minutes by 60 to get decimal remainder of degrees, e.g.
27 minutes = 0.45 degrees. The declination will be rounded up from
16.45 to 16.5 to conform to the data entry format of one decimal place.
2. Read or Set the Magnetic Declination
With the Magellan sensor connected through the Interface Module to a
computer, start HyperTerminal program. (This program can be accessed
through the Windows Start button - All Programs - Accessories Communications.) The automatic weather data output should start
streaming.

Tables and Formulas
Wind Chill Chart
In 2001, NWS implemented an updated Wind chill Temperature (WCT)
index. The change improves upon the former WCT Index used by the
NWS and the Meteorological Services of Canada, which was based on
the 1945 Siple and Passel Index.
In the fall of 2000, the Office of the Federal Coordinator for
Meteorological Services and Supporting Research (OFCM) formed a
group consisting of several Federal agencies, MSC, the academic
community (Indiana University-Purdue University in Indianapolis (IUPUI),
University of Delaware and University of Missouri), and the International
Society of Biometeorology to evaluate and improve the windchill formula.
The group, chaired by the NWS, is called the Joint Action Group for
temperature Indices (JAG/TI). JAG/TI's goal is to upgrade and
standardize the index for temperature extremes internationally (e.g. Wind
chill Index).
The current formula uses advances in science, technology, and
computer modeling to provide a more accurate, understandable, and
useful formula for calculating the dangers from winter winds and freezing
temperatures.
