Instruction Manual
1.0 INTRODUCTION
The WMS-25 Modular Weather Stations are meteorological systems designed to be a
“user friendly” solution for data storage and real-time monitoring of weather conditions.
This manual covers all three versions: Desktop, NEMA, and Portable. The data logger
and general operation is the same on all versions.
The standard sensor package includes 6 weather parameters: wind speed and
direction, temperature and relative humidity, barometric pressure, and precipitation,
(additional optional sensors can be added), a 5-foot tripod and 5-foot vertical mast for
sensor mounting, and a data logger with LCD display. The portable systems have a
3-foot tripod with 6-foot mast. Pressure and rain sensors are optional.
No computer is required for setup and viewing data. A simple menu interface using the
LCD display and three front panel buttons makes setup easy.
Data is recorded directly to a Secure Digital (SD™) card, providing convenient data
downloads and storage for many months of data. The data logger is compatible with
standard SD cards up to 2GB. Logging at 1 minute intervals, a 2GB card will store over
5 years of data. A new file is created and saved to the card each day.
An RS232 serial output is standard and allows real time viewing of the data on a PC
with any terminal emulator program, for example HyperTerminal, Putty, or the optional
WMS-25-STR Graphical Display Software.
Using the stored recorded data is simple. The SD card is removed from the logger,
inserted into the SD card reader, then plugged in to the USB port on your computer
(Windows, Macintosh, and Linux). This will then show up as a drive. To view and graph
the data, click on the file corresponding to the day of interest. Microsoft Excel,
OpenOffice.org, or any spreadsheet program can be used to view, graph, and analyze
your data.

2.0 DESCRIPTION
The WMS-25 Weather Station has been set up and configured for the six standard
sensors: speed, direction, temperature, humidity, barometric pressure, and rainfall. It
has been shipped for a plug and play operation.
Data Logger
The WMS-25 data logger’s easy-to-use interface includes a 16-character by 2-line
backlit LCD screen, which displays current information and is used for configuring the
data logger. A simple menu-driven interface using the LCD and three front panel
buttons makes setup easy. A bright back-light makes the data logger easy to use at
night. A Secure Digital (SD™) card slot makes recording and accessing data easy.
Sensors
The standard WMS-25 sensors have been designed to be rugged, compact, and
lightweight. They interface directly to the data logger without the need for additional
signal conditioning.
Wind Speed and Direction ~ WMS-25-WSD
The wind sensor combines a three-cup anemometer and a wind vane on a single axis.
The anemometer is a contact-type wind sensor which, when rotated by the wind,
triggers a series of momentary switch closures that are directly related to wind speed.
The wind vane uses a 20K ohm potentiometer to sense direction changes. Depending
on the position of the potentiometer wiper, an analog voltage is output that corresponds
to the position of the vane. By orienting the vane to North (360 degrees) during
installation, wind can be easily calculated from the output voltage. The resolution of the
wind vane is 1 degree (azimuth display) or 16 compass points (on LCD display only).
Barometric Pressure ~ WMS-25-BP (optional on portable stations)
The barometric pressure sensor is set for sea level when it leaves the factory.
It will read absolute pressure. Barometric pressure varies with elevation, the data logger
can be set up to read corrected to sea level pressure for the elevation at which it is
installed. This is done adding the correct offset in inches in the analog setup menu. You
will need to know the correction in inches for the elevation at your location before you
change it. Instructions are provided in the manual.
Temperature and Relative Humidity ~ WMS-25-TH
The WMS-25-TH is a combination temperature and relative humidity sensor installed a
solar radiation shield. Temperature and humidity are sensed using a sensor element
which changes voltage with temperature and humidity fluctuations. (The warm-up time
to stabilize is 10 minutes.)
2
Rain ~ WMS-25-RG (optional on portable stations)
The 8 inch rain gauge with mast mounting arm provided with the WMS-25 is a
traditional tipping bucket design. Resolution is 0.01 inches (0.254 mm) per tip.
3.0 CONFIGURATION AND OPERATION
Data Logger
Navigation Buttons
– Scrolls through display screens and allows user
setup menus. Moves values in the negative
direction.
SELECT Press to enter ‘Setup’ menu.
• Scrolls through display screens and allows
setup menus. Moves values in the positive
direction.
All buttons respond to a single press. Holding a
button will not cause multiple actions to occur.
Secure Digital™ Card Slot
The data logger has a spring-loaded memory card slot. To insert a Secure Digital™
(SD™) card, place the card face up into the slot on the front panel and press the card
inwards until the card clicks into place. To remove card, press the card slightly inward
and the card will release.
The card should not be removed by pulling it out without first pressing it inwards. If a
card is pulled out in this manner, both the memory card and the card socket may be
damaged.
Menus
On the data logger display, the primary menus are: Main Setup Menu, Wind
Channels, Analog Channels, and Counter Channels. Submenus of the Main Setup
Menu are: Date Setup, Time Setup, Anemometer Setup, Wind Vane Setup, Log
Interval, Counter Setup, Analog Setup, Channels to Log, RS232 Setup, Wind Vane
Setup, Site Name Setup, Sync. Setup, and Restore Defaults. The wind data logger
has three keys: – which moves backwards or down (depending on the screen);
SELECT which selects, sets, or moves to the next character; and • which moves
forwards or up (depending on the screen). Since the WS-25 logger has been
pre-configured, there is no need to go into the sensor setup menus.
3
Setting the Time and Date
Using the ‘Time’ and ‘Date’ screens, one can both view and set the current date and
time. The wind data logger incorporates a real-time clock that keeps accurate time while
power is disconnected. The clock does not automatically adjust for daylight savings;
however it does automatically adjust for leap years. The date format used throughout
the wind data logger is YYYY-MM-DD.
See the CONFIGURATION AND OPERATION Table below for sample screen shots
and detailed instructions for changing time and date. The same method is used with all
data logger setup screens.
1 minute logging at the top of the minute :00 has been selected rather then free running
4
Data Logging
The WMS-25 data logger can record measurements directly to an industry standard
Secure Digital™ or Multi-Media Card™. The data logger records both raw and
processed values in a simple text format that can be opened with any spreadsheet or
text editor.
Starting and Stopping Logging
Logging commences after the memory card is inserted into the data logger and
terminates after it is removed. Use the Logging Status screen to verify that the data
logger is recording. If a memory card is inserted but the data logger shows “NOT
READY” then there is a problem and the data logger WILL NOT record anything. Check
to be sure the card is fully inserted and meets the memory card requirements outlined
below.
Memory Card Requirements
The WMS-25 data logger is compatible with all sizes of SD (Secure Digital™) or MMC
(Multi-Media Card™) cards; however, it will not work with Secure Digital High Capacity
(SDHC) cards.
There is no need to format the SD card for this data logger mode.
Data
The WMS-25 data logger generates one file per calendar day. The file name is
YYYYMMDD.CSV (ex. 20160713.CSV) where YYYY is the four-digit year, MM is the
two-digit month, and DD is the two-digit day. Each file is stored in the main directory or
folder of the SD or MMC. The data logger also writes two other files that contain meta
information about the channels being logged. For most applications these files can be
ignored. The file consists of one record per line. On most computers, a single file can
be opened in a text editor by simply double clicking on its icon.
The data logger records Comma Separated Variable (CSV) files to the memory card.
CSV data can be used by nearly any spreadsheet software. First launch the program,
then use the ‘Open’ command in the File menu to select the CSV file created by the
data logger. (The date modified column has no function and can be ignored.)

Microsoft Excel, Gnumeric, and Open Office.org Calculator are all good spreadsheet
programs. Gnumeric and OpenOffice.org Calc are free and can be downloaded from
the Internet.

9. Done.
Refer to the “Quick Start” instruction booklet for sensor wiring connections,
power connections, and other special information.
Tripod Towers
The five-foot tripod tower provided with the WMS-25 is constructed of steel tubing for
durability and strength. Horizontal bracing is a feature of the tripod tower. The tripod’s
foot brackets can be bolted onto a concrete foundation or a wooden platform. The wind
speed and direction sensor mounts on top (the tapered end) of the five-foot aluminum
sensor mast. The solar radiation shield (for the temperature and humidity sensor) and
the rain gauge mounting arm are supplied with u-bolts to clamp onto this mast. For
stability, we recommend that the mast be inserted into both of the tripod’s collar clamps.
Guy kits are recommended for areas of high winds and ground kits are recommended
for areas with lightning activity.
The WMS-25P Portable Stations include a 3-foot tripod, with two 3-foot mast that
connect together end to end.
Caution: When installing the wind sensor, make sure that the sensor and cable are well
clear of any power lines.

Lightning Protection and Grounding
A copper lightning protection ground lug, located on the data acquisition NEMA module,
this is the path to ground for all of the lightning protection circuitry in the
WMS-25-NEMA.
Connect a heavy copper wire to this lug the other end connects to a grounded outlet or
water pipe or Earth ground. In areas subject to severe lightning activity, we recommend
that you install a grounding rod.
Power Connections
The WMS-25 runs on 12Vdc power. It can be operated from a standard AC/DC power
adapter connected to a 110-240 Vac outlet, or from a 12Vdc battery on NEMA and
portable versions.
Main Memory Battery Backup
The WMS-25 main memory has a lithium battery backup so setup parameters, as well
the date and time stored data, will be retained even if the primary power source is
interrupted.
RS232 Interface
An RS232 interface is available, but not needed. It is used when connecting the
optional real time graphical display software to a PC.
The standard text data can be viewed on any terminal program. A new line on data will
be sent out every minute.
Sample data ....

The WMS-25 serial data communication between the user and the WMS-25 is
accomplished using RS232 communications protocol designed for short-distance use.
The standard 6-foot serial interface cable that connects the data logger to the computer
is terminated with a 9-pin “D” connector. The serial cable can be extended up to 200
feet.
For computers without a serial port, a USB-to-Serial converter may be used. When
installing the converter, be sure to note the Com port number it is assigned.

Testing the Connection
Once the WMS-25 is connected to the computer, the connection can be tested by
turning the power on to the WMS-25. If the RS232 connection is sound, a line of data
will show every minute.
2016-06-15 16:02:30,1.9,3.0,19,,,,,,,,,0.00,88,12.18,,,,71.829,38.556,29.721,,67
A RS232 Output Tester Light is supplied with the unit. If the serial output is functioning,
the red light should flash every minute.
If the WMS-25 is functioning but you see nothing on the PC screen, the wrong serial
port may be selected. Try selecting Com 3 or another functioning serial port. You can
see a list of available ports in Computer > System Properties > Device Manager >

Refer to the Quick Start As Shipped sheet for your exact setup.
Converting Wind Speed Pulse Count to Average Wind Speed
The ‘Wind Pulses’ screen in the Main Display Loop shows the number of anemometer
revolutions since the last write to the memory card. The pulse count information can easily be
converted to average wind speed using the following formula:
Average Wind Speed = ((WCx/sample_interval) * anemo_m) + ( anemo_b)
Example using the following snippet of data from the data logger WMS-25-WSD sensor and a
sampling interval of 60 seconds recording in MPH:
2016-06-15 16:11:00,18.0,19.4,810
As seen in the data snippet above or the reading from the data logger ‘Wind Pulse’ screen,
WC0 = 810. This information can then be used with the formula above:
Average MPH = ((810/60) * 1.25) + 0.0 = 16.87 MPH
A complete data logger manual with internal PCB schematics is available upon request.
