2 HARDWARE INSTALLATION
There are two basic types of installations: direct connection and phone modem
connection. Direct connection involves connecting the computer directly to the
WeatherLink. Phone modem connection refers specifically to any installation
where the WeatherLink is connected to a modem and you communicate with the
WeatherLink via a modem at your computer. Requirements and installation for
each type of connection differ, and are explained separately below.
HARDWARE REQUIREMENTS
The required hardware differs depending on whether you are attempting to make
a direct connection or a phone modem connection.
Direct Connection Hardware Requirements
In addition to the provided hardware, the following are required for a direct connection.
▲ Computer running Windows™ 3.1, 95, or NT 4.0 with at least 5 MB of free disk
space
The amount of space necessary for the data files depends on the archive interval. Database files containing data stored at a 30 minute archive interval
require approximately 36K of disk space per month of data. The file size
changes in a linear fashion depending on the archive interval. For example,
data stored at a 1 minute interval requires approximately 1 MB/month while
the data stored at a 2 hour interval requires approximately 9K/month.
▲ 4MB RAM
▲ Windows-Compatible Display
VGA (16 Colors) minimum. SVGA (256 Colors) recommended.
▲ One Free Serial Port
▲ Fax Modem
A fax modem is required to take advantage of the software’s AutoFax feature
(see ”Auto Fax” on page 32). If you do not plan to use the AutoFax feature, a
fax modem is not required for a direct connection.
Phone Modem Connection Hardware Requirements
In addition to the provided hardware, the following hardware is required for a
phone modem connection.
▲ Computer running Windows™ 3.1, 95, or NT 4.0 with at least 5 MB of free disk
space
See “Direct Connection Hardware Requirements” above for hard disk space
requirements.

HARDWARE INSTALLATION
Direct Connection
Direct Connection Installation
1. Make a note of your station’s current barometric pressure, total rainfall, and (if applicable) calibration numbers.
You must remove power from the station console to install the WeatherLink,
which will cause these values to be erased. Use the WeatherLink software to
reenter these values after restoring power to the station.
2. Remove the mounting base from the console and remove all power by removing the
AC-power adapter and battery backup.
Failure to remove power to the console before installing the WeatherLink may
cause damage to the WeatherLink or console.
3. Insert the cable plug at the end of the short cable coming from the WeatherLink into
the jack marked WEATHERLINK on the bottom of the console.
CAUTION: Make sure that whenever you connect or disconnect the WeatherLink from the console that the console is NOT powered up. Plugging or unplugging the WeatherLink
while power is applied can damage or lock up the WeatherLink.
4. Restore power to the weather station by reattaching the power adapter and battery.
The weather station should beep three times. The third beep, which should
occur within 30 seconds, indicates that the WeatherLink is operating correctly.
5. Place the WeatherLink inside the mounting base and reattach the mounting base.
As you do so, guide the cables through the slots in the mounting base.
PLACE WEATHERLINK INSIDE BASE.
6. Locate a free serial port on the back of your computer and connect the appropriate
adapter (DB9 or DB25) to that serial port.
7. Insert the cable plug at the end of the long cable coming from the WeatherLink into
either the DB9 or DB25 adapter.
The cable which connects the WeatherLink to the computer is 8 feet (2.4 m)
long. If you need to mount the station console more than 8 feet from the computer, use a 40’ (12 m) standard 4-conductor extension cable. Do not attempt
to use more than 40’ of extension cable, or the WeatherLink may have difficulty “communicating” with the computer. If you need to mount the station
console farther away, you will need to use the Short-Range Modem Pair.

Phone Modem Connection
A Few Notes About Phone Modem Connections
If you indicate a phone modem connection when setting up your station (see
“Serial Port” on page 20), the software automatically dials the station whenever
you attempt to initiate a program action which requires the software to “talk” to
the WeatherLink.
While connected to a phone modem station, an “On-Line” icon appears in the
toolbar. This icon indicates that you are on-line and may be used to hang up a
remote connection. To hang up, choose the On-Line icon from the toolbar or
choose Hang Up from the File menu.
TOOLBAR WITH ON-LINE ICON
Once connected, the software will remain on-line until you choose to hang up.
The software remains on line whether or not you are doing something which
requires it to be connected.
Note: If you are on-line at the time of a schedule automatic download, the automatic download is
cancelled.

3 SOFTWARE INSTALLATION AND SETUP
This chapter covers software installation and setup.
INSTALLING THE SOFTWARE
1. Place the Install Disk in your disk drive.
2. Choose Run from the File menu, type A:SETUP (or B:SETUP), and choose OK to begin the
installation.
3. Follow the on-screen prompts to complete the installation.
RUNNING THE SOFTWARE
To run the software, double-click on the WeatherLink 4 icon. If you have no stations in the program directory when you run the software, the software will
prompt you to add a station (see “Adding a Station” below for details). If you
have more than one station in the program directory when you run the software,
the software will prompt you to indicate which station you’d like to open.
ADDING A STATION
In order to interact with your station, you must add a station, which entails naming
the station, configuring the software to work with that station and with your computer hardware, and setting station values such as time, barometric pressure, total
rainfall, and calibration numbers. For performance reasons, the software reads
these values from the station configuration file (see ”Station Configuration File” on
page 94 for more information) rather than from the station itself. Therefore, you
must set station values from the software. If you set station values from the station’s console, the readings you see in the bulletin, database, strip charts, reports,
and plots may not agree with your station’s readings.
Adding a Station
1. Choose New Station from the File menu.
The software opens the Add New Station dialog box.
NEW STATION
9
SOFTWARE INSTALLATION AND SETUP
Adding a Station
2. Type the station name into the text box.
The station name may be up to 40 characters/spaces long. Note that the software uses the first eight characters of the station name (not counting spaces or
punctuation marks) as the name of the directory into which it saves this station’s database and configuration files. The first eight characters of each station name must, therefore, be unique. The software also uses the first three
characters as the file extension for that station’s database files (the first three
characters need not be unique).
3. Choose OK.
The software saves the station, creates a directory and subdirectories for that
station, and prompts you to indicate whether you want to enter the walkthrough procedure.
START WALKTHROUGH CONFIRMATION
About the Walkthrough
The software includes a station setup walkthrough which steps you through the
station configuration procedure. After adding a new station, the software automatically prompts you to indicate whether or not you want to be walked through
the configuration procedure. You may, of course, choose No and set up the station
by choosing all of the necessary commands from the menus. A Walkthrough command is included in the Setup menu which allows you to go through the walkthrough procedure at any time.
Note: Where necessary, the software will automatically dial a phone modem station. See “A Few
Notes About Phone Modem Connections” on page 8 for instructions on dialing and hanging
up.
If you choose Yes to begin the walkthrough, the software takes you through the
following dialog boxes:
▲ Station Configuration (see ”Station Config” on page 19)
Set station name, model, accessories, download options, and data file extension.
▲ Choose Units (see ”Select Units” on page 22)
Select units of measure in which station information is displayed.
▲ Serial Port Settings (see ”Serial Port” on page 20)
Set COM port to which WeatherLink is connected. Specify modem connection
settings such as baud rate, phone number, and modem initialization string.
▲ Set Barometer (see ”Set Barometer” on page 24)
Set barometric pressure on station and software. You must enter this information from the software if you want your station and software readings to
agree.

▲ Enter Total Rainfall (see ”Set Total Rain” on page 27)
Set total rainfall amount on station and software. You must enter this information from the software if you want you station and software readings to agree.
▲ Set Time and Date (see ”Set Time” on page 23)
Set the time and date on the station, software, and computer to make sure all
three are synchronized.
Note: When you set the time and date, you will be prompted to clear your archive memory (see
”Archive Memory” on page 91 for information on the archive memory). If you do not clear
archive memory, you may end up with data stored at an incorrect time or duplicate
records. We recommend that you download before setting the time (unless you are creating a brand new station) so you may safely clear the archive memory.
▲ Set Archive Interval (see ”Set Archive Interval” on page 24)
Select the interval at which you want data stored to the WeatherLink’s archive
memory (see ”Archive Memory” on page 91).
▲ Set Station Alarms (see ”Set Alarms” on page 28)
Set alarm thresholds on the station.
▲ Set Auto Clear (see ”Auto Clear” on page 30)

SOFTWARE INSTALLATION AND SETUP
Finding the Correct Serial Port
FINDING THE CORRECT SERIAL PORT
The software contains a procedure for locating the serial port to which your station is connected or determining whether that serial port is working. Using the
Loopback command (as opposed to Test) will help you determine whether a communication problem is being caused by the serial port or by the WeatherLink.
Note: This procedure will only work for direct connections. If you are making a phone modem connection, you may want to simply check the communications software you normally use for the
correct serial port setting. Otherwise, you must consult the documentation supplied with your
modem.
In order to use this procedure, you will need the loopback connector (the short
cable with a phone jack on one end and a red plastic tip on the other) supplied
with your Weatherlink software package.
1. If necessary, disconnect the 40-foot WeatherLink cable from the DB9 or DB25 adapter
which is connected to the COM port.
2. Insert the loopback connector into the DB9 or DB25 adapter.
3. Choose Serial Port from the Setup menu.
The software opens the Serial Port dialog box.
SERIAL PORT
4. Choose Loopback.
The software will search all standard serial ports and inform you of the COM
port at which the loopback connector is located.
LOOPBACK CONNECTOR FOUND
The software automatically selects the correct COM port for you in the Serial Port
dialog box. If it cannot find the loopback connector at any COM port, your serial
port is not working. Consult your computer documentation for help.
12
4 USING THE SOFTWARE
Everything you need to know about running the software (once it is correctly
installed and set up) is explained in this chapter.
WEATHER STATION MODELS
Depending on which station model (Weather Monitor II®, Weather Wizard III®,
etc.) you are using and which optional sensors (Rain Collector or External Temperature/Humidity Sensor) you have connected to your station, certain information and options explained in this manual may not be available. The software may
only display and plot data for which your weather station has a sensor. For example, if you have a Weather Wizard III, you may not plot, view, or print barometric
pressure information.
MULTIPLE STATIONS
The software can support the use of any number of weather stations with a single
version of the program. Each station must connect to its own WeatherLink, however. If you have set up more than one station, whenever you load the software
you will be prompted to open a station.
OPEN STATION DIALOG BOX
All program actions affect the open station. To open a different station, choose
Open Station from the File menu (see “Open Station” on page 15).

Bulletin
The bulletin provides a graphic representation of current weather conditions
(with the numeric reading displayed as well) which updates in real-time.
BULLETIN
For all bar graphs (outside temperature, for example), highs and lows are represented by yellow lines which appear above the bar (high) or within the bar (low).
When you first open the bulletin window, the software prompts you to indicate
whether you want to download highs and lows from the station. Downloading
highs and lows causes the software to read highs and lows from the weather station and display them on the weather bulletin. If you download highs and lows it
takes a bit longer to open the bulletin window. If you do not download highs and
lows, the highs and lows shown in the bulletin window will only reflect the highs
and lows recorded while the bulletin is open. As long as the bulletin is open, the
software automatically updates highs and lows as they occur. (If a scheduled
Auto Clear occurs while the bulletin is open, any high or low that is cleared on the
console is also cleared on the bulletin.)
The bulletin displays a line graph of barometric pressure over the past six hours.
When you first open the bulletin window, the software graphs the current barometric pressure and any barometric pressure data which exists in your database
for the past six hours. While the bulletin is open, the software plots another point
on this graph every 15 minutes.

The software includes powerful plotting capabilities which allow you to view and
compare data in graphical format. The plot interface has been designed so that
almost all plot features may be accessed directly from the plot window. You may
use menu commands if you find it easier, of course. Menu commands are

Color menu are added to the main menu bar and some new commands (Open
Plot, Save Plot, Open Plot Template, and Save Plot Template) are added to the File
menu. The use of the Plot menu, Colors menu, and the Open and Save commands
are explained below.
The three most basic elements of any plot are the variables (the weather conditions you are plotting), the date, and the plot span (the length of time over which
you are plotting those conditions). The software allows you to quickly and simply
select those three elements and also includes many other useful features which
make it easier to view and compare data. Almost all of the plot features may be
accessed directly from the plot window.

USING THE STRIP CHARTS
The strip charts are four line graphs, stacked one on top of another, onto which
you may plot any data contained in your database. Unlike the normal plots, however, strip charts can also be set to update at each archive interval allowing you to
view changes in weather conditions as they occur. Whenever you open the strip
chart window, the software automatically downloads data. Thereafter, as long as
the strip chart is in “auto update” mode, the software will download and update
the strip charts at each archive interval.
When you activate the Strip Chart window, a Strip Chart menu and a Color menu
are added to the main menu bar and two new commands (Open Chart and Save
Chart) are added to the File menu. The use of the Strip Chart menu, Open Chart,
and Save Chart are explained below. The use of the color menu is explained in
“Colors Menu” on page 80.

View Historical Data
You may use the scroll bar along the bottom of the strip chart window to view historical data on the strip charts. Clicking on the scroll arrows moves the strip chart
forward or backward one day at a time. Clicking the scroll bar moves the strip
chart one span at a time. Dragging the scroll box allows you to quickly find a specific date. As you drag the scroll box, watch the bottom of the window until the
desired date appears, then release the scroll box.
Note: Viewing historical data takes the strip chart out of auto update mode.
Place the Strip Chart Into Auto Update Mode
When you first open the strip chart window, the strip chart is automatically
placed into auto update mode. It will remain in that mode (downloading and
updating the charts at each archive interval) until you click on the scroll bar (to
view historical data) at which point it is automatically taken out of auto update
mode. To return to auto update mode, choose Auto Update from the Strip Chart
menu. If necessary, the software will download any data in the archive memory
before entering auto update mode. The strip charts will automatically move to the
most current date in the database.

USING THE YEARLY RAINFALL DATABASE
The WeatherLink software keeps a separate rainfall database which enables you
to view accumulated rainfall totals broken down by month and year. If you have
existing data in your main weather database, the software will create the rainfall
database using the data stored in your main weather database. Once created, the
software updates the rainfall database after each download. It is also possible to
alter any existing entry in the rainfall database and to enter rainfall totals for
months and years which are not contained in your main weather database.
When the Yearly Rainfall window is active, a Rain menu is
added to the menu bar. This menu allows you to start a new
rainfall database, edit data, add years of rainfall data, or

DEGREE-DAYS
The instructions below explain how to use the WeatherLink Software’s degreeday reporting feature to track the development of crops and/or pests. For information on degree-days, see “Degree-Days” on page 97. In order to use degreedays, you must determine the developmental threshold(s) for the desired crop or
pest. The base developmental threshold is the temperature at and below which
development stops. Above the base threshold, development increases until the
temperature reaches the upper threshold, over which development rate remains
constant. Information on degree-day thresholds is available from your county
agricultural agent or university agricultural extension service.

into the text box.
85
USING THE SOFTWARE
Degree-Days
▲ Degree-Day Calculation Method
Choose the method by which degree-days are calculated.
▲ Growing Degree-Day “Cut-Off” Method
The software uses the highest temperature and the lowest temperature
for a given day to calculate the average temperature for that day. Note,
however, that if the low temperature is below the base threshold, the
software uses the base threshold as the low temperature when determining average temperature for the day. In addition, if the high temperature is above the upper threshold, the software uses the upper
threshold as the high temperature when determining average temperature. For this method, both thresholds must be entered.
The difference between the average temperature and the base threshold is assumed to be the number of degree-days accumulated on that
day. (For example, if the average of the highest and lowerst temperatures was 24˚ above the base threshold, the software would assume 24
degree-days for the entire day.)
Note: Unless 15 hours worth of records exist in the database for a day (through 3pm),
the software will not calculate degree-days for that day.
▲ High/Low Method
The software uses the highest temperature and the lowest temperature
for a given day to calculate the average temperature for that day. Note,
however, that if the high temperature is above the upper threshold the
software uses the upper threshold as the high temperature when determining average temperature for the day. (If no upper threshold is
entered, the high temperature will not be “cut off” in this way.) For
this method, the upper threshold need not be entered.
The difference between the average temperature and the base threshold is assumed to be the number of degree-days accumulated on that
day. (For example, if the average of the highest and lowest temperatures was 24˚ above the base threshold, the software would assume 24
degree-days for the entire day.)
Note: Unless 15 hours worth of records exist in the database for a day (through 3pm),
the software will not calculate degree-days for that day.
▲ Integration Method
The software calculates degree-days using the average temperature for
an interval and the interval time. For example, if the average temperature during a 15 minute interval was 24˚ above the base threshold, the
software would calculate 0.25 degree-days dudring that interval (24˚ *
15 minutes in interval / 1440 minutes per day). The number of degreedays during each interval are added together to arrive at a degree-day
total. This method calculates degree-day totals more accurately than
the high/low method.

5 TECHNICAL REFERENCE
This chapter covers several technical topics which may help you better understand and use the software.
ARCHIVE MEMORY VS. DATABASE
There are two places where the WeatherLink stores weather data: the archive
memory and the database.
Archive Memory
The archive memory is the weather information storage area in the WeatherLink
itself. At each archive interval the WeatherLink stores one record to archive memory. The WeatherLink has room in the archive memory for approximately 1 day of
weather data for each minute in the archive interval. For example, if you use the 1
minute archive interval, the WeatherLink may store approximately 1 day of data.
If you use the 30 minute archive interval, the WeatherLink may store approximately 30 days of data. If you use the 2 hour archive interval (120 minutes), the
WeatherLink may store approximately 120 days of data.
Note: To aid you in determining when you need to download, the software shows you what percent
of archive memory is full whenever you download data.
When the archive memory “fills” the WeatherLink overwrites old data each time
it stores a new record. Because of this, it is best to select the longest archive interval which suits your purpose. In addition, make sure to download data before
your archive memory fills or you will have gaps in your database.
Database
The database is the permanent record of data stored on disk. When you download, the software transfers all information in the archive memory to the computer and writes the information into the appropriate database files. If you do not
clear the archive memory when downloading data (see “Station Config” on
page 19), the software will incorporate any data that post-dates the existing database. The software will not overwrite existing data. This means that if, for example, your station loses power and, upon power up, begins logging data at the
default date January 1, this data will not make it into an existing database as it will
precede the most recent date.
As the software writes the data to database files, it calculates the average wind
chill and average dew point. The temperature/humidity index, Equilibrium
Moisture Content, and air density, on the other hand, are calculated by the software as needed.
The software stores data to disk in monthly blocks, each of which is a separate
data file in the weather station's directory. The name of the data file indicates the
year and the month of the data and has a three character file extension which indicates the station from which that data came.
91
TECHNICAL REFERENCE
Automatic Download
AUTOMATIC DOWNLOAD
The automatic download feature allows you to specify the times at which you
wish the WeatherLink Software to automatically download data from selected
stations (see “Auto Download” on page 31). As long as the computer is on and the
software is running, the software will prompt you (at the specified times) to indicate whether or not you wish to download data. If you are present, you may
choose OK to download or Cancel to quit the download. If you do not make a
choice within 10 seconds (if your computer is unattended, for example) the software automatically downloads data. If you have a remote connection, the software automatically dials and hangs up the connection for you. An entry is made
in the log file (see “View Log” on page 17) to indicate whether or not the automatic download was successful.
Note: The automatic download procedure is disabled if you are actually connected to a remote station at the automatic download time.
The software checks every 20 seconds to see if an automatic download is scheduled. If you have multiple stations scheduled for download, the software will finish the download of the one and then wait until the next “check point” to start the
download of the next one.
Under certain circumstances, the software will actually download data up to 10
minutes after the automatic download time. This feature allows the software to
automatically download data from a station if you launch the software a little
later than the automatic download time. For example, if a station is set to download at 12:00, and you launch the software at 12:05, the software will still download the station’s data.
Note: If you have set automatic clear and automatic download for the same time, the software performs the automatic download first.
AUTOMATIC CLEAR
The automatic clear feature enables you to specify a time at which you wish the
software to clear selected highs and lows (and rainfall totals) every day (see
“Auto Clear” on page 30).
As long as the computer is on and the software is running, the software will
prompt you (at the specified time) to indicate whether or not you wish to clear
highs/lows. If you are present, you may choose OK to clear or Cancel to quit the
automatic clear. If you do not make a choice within 10 seconds (if your computer
is unattended, for example) the software automatically clears the highs/lows. If
you have a remote connection, the software automatically dials and hangs up the
connection for you. An entry is made in the log file (see “View Log” on page 17) to
indicate whether or not the automatic clear was successful.
If an Auto Clear occurs while the bulletin or summary windows are open, the
software will update the highs and lows displayed in the open windows.
Note: If you have set automatic clear and automatic download for the same time, the software performs the automatic download first.
92
TECHNICAL REFERENCE
Calibration Numbers
CALIBRATION NUMBERS
To increase performance, the software maintains calibration numbers separately
from the weather station. If you do not set calibration numbers from the software,
the weather station and software will not “agree” on what the calibration number
is. Therefore, you must set all calibration numbers (temperature, humidity,
barometer) from the software.
The following explanation of how the station and software determine barometric
pressure may help you understand this better.
The weather station actually reads atmospheric pressure not barometric pressure.
When you set the barometric pressure from the station console, the station automatically calculates the difference between the barometric pressure you enter and
the atmospheric pressure it reads. This difference gets stored as the barometric
pressure calibration number. When displaying the barometric pressure, the station reads atmospheric pressure and adds the calibration number to determine
barometric pressure.
When you enter barometric pressure from the software, the software calculates
the calibration number and stores it in the weather station’s memory (in the same
way it would if you set the barometer from the station console) and in the station’s configuration file. The station calculates barometric pressure normally,
while the software reads atmospheric pressure from the station and the calibration number from the station configuration file in order to determine the barometric pressure.
If you enter barometric pressure (or any calibration number) from the software,
both the software and station will “agree” on the calibration number. If you enter
barometric pressure (or any calibration number) from the weather station console,
nothing gets stored in the station’s configuration file. The calibration number in
the software now differs from the calibration number in the station, and your bulletin readings and database will be incorrect.
Note: The software does not support wind speed calibration numbers.
DATABASE ORGANIZATION
Station Directory
When you create a new station the software creates a station directory (using the
first eight characters of the station name, not including any spaces and punctuation) in the root program directory. Inside of this directory, the software will create
subdirectories to contain station-specific files.
▲ DATANOTE
The DATANOTE directory contains any notes you have entered for database
records. The software assigns its own coded file names to database files. If you
want to delete a note, it is best to do so from the software. Do not rename a
note file.
▲ PLOT
The software automatically creates a PLOT directory into which you may
store plots, plot templates, and strip chart templates. You may, of course, save
plot and strip chart files into any directory you wish.
93
TECHNICAL REFERENCE
Database Organization
▲ DEGDAYS
The software automatically creates a DEGDAYS directory into which it stores
all PC degree-day information.
Station Configuration File
When you add a station, the software creates a station configuration file (called
“station.cfg”) in the station directory. Each station has its own discrete configuration file which saves the following program settings for the appropriate station.
▲ Station Configuration Settings
▲ Serial Port Settings
▲ Calibration Numbers
See “Calibration Numbers” on page 93.
In order to recognize a station, you will need a station configuration file (in the
same directory as the database files). When opening a station, the software locates
station configuration files and reads the station name from them. If you copy
database files (to share or transfer data, for example) make sure to copy the station configuration file with them. As long as the station configuration file is in the
same directory as the database files, you should be able to read the database files
normally.
Database Files
The software stores downloaded data in monthly files. Whenever you download,
the software saves database files into the open station's directory. The database
file name indicates the year and month of the data. The three character file extension indicates the station from which they were downloaded. Database files containing data stored at a 30 minute archive interval require approximately 36K of
disk space per month of data. The file size changes in a linear fashion depending
on the archive interval. For example, data stored at a 1 minute interval requires
approximately 1MB/month while the data stored at a 2 hour interval requires
approximately 9K/month.
You cannot combine database files. For example, if you download half of your
April data to one directory and the other half to another directory, you cannot
combine the two database files into a single file containing all of your April data.
(If you do not clear your archive memory, you may be able to download the data
into the correct file at a later date.) Take care when downloading to make sure the
correct station is the open station.

Weather Data Calculations
WEATHER DATA CALCULATIONS
The following section details how the software calculates the data for each
weather function to arrive at an entry for the archive memory or database.
Temperature
The Weatherlink samples the temperature reading from the station a number of
times during the interval and then averages all those readings to arrive at the
average temperature for the interval. The number of times the Weatherlink samples the temperature depends on the archive interval.

High and Low Temperature
The first time the Weatherlink samples outside temperature during the interval it
writes that value into both a high and low register in memory. Every subsequent
time the Weatherlink samples the temperature, it compares the current value to
the value in the registers and if the current value is higher or lower, replaces the
old value with the current value. Whatever value is in the register at the time of
the archive gets written into archive memory.
Barometric Pressure
The Weatherlink samples the barometric pressure at the time of the archive and
writes that value into the archive memory.
Wind Speed
The Weatherlink samples the wind speed reading the same number of times per
interval as temperature and averages the readings together to arrive at the average wind speed for the interval.
High Wind Speed
The Weatherlink is constantly checking for a new high wind speed. The highest
wind speed value recorded during the interval gets written into archive memory.
Wind Direction
The Weatherlink samples the wind direction reading the same number of times
per interval as temperature. If wind speed is greater than 0 when the Weatherlink
samples wind direction, it places a “marker” into one of sixteen “bins” which correspond to the sixteen compass points. At the time of the archive, the Weatherlink
95
TECHNICAL REFERENCE
Weather Data Calculations
determines which bin contains the most markers and writes the corresponding
wind direction to the archive memory as the dominant wind direction.
Note: During intervals with very low wind speed, it is possible for no wind direction to be recorded,
because wind speed was always 0 when direction was sampled. In this case, wind direction
for the interval appears as a pair of dashes (--).
Temperature/Humidity Index
Temperature/humidity index (THI) uses the temperature and the relative humidity to determine how hot the air actually “feels.” When humidity is high (i.e., the
air is saturated with water vapor) the apparent temperature will be higher than
the air temperature because perspiration cannot readily evaporate into the surrounding air. Technically, THI is calculable only when air temperature is above
68° F (20° C) because it is a measure of heat stress, which is not significant at lower
temperatures. If temperature is below 68° F (20° C), the software reports THI as
being equal to outside temperature. Conversely, 125° F (52° C) is the highest T-H
Index for which calculation factors are available.
In terms of storage to the WeatherLink and database, temperature/humidity
index (THI) is a very special case. It is not stored in archive memory or in the database, rather it is calculated “on-the-fly” as necessary (for example, when plotting
or displaying database information). When THI data is needed, the software calculates an average THI for each archive interval based on the temperature and
humidity readings for the archive period.
Wind Chill
Wind chill is not stored in archive memory, rather it is calculated as the data gets
written to the database file. The software calculates wind chill based on the temperature and wind speed readings for the archive period (that is, the average temperature and the average wind speed during the interval).
Dew Point
Dew point is not stored in archive memory, rather it is calculated as the data gets
written to the database file. The software calculates dew point based on the average temperature during the interval and an approximation of the average outside
humidity during the interval. To arrive at an “average” outside humidity reading,
the software averages the outside humidity for the current archive interval and
the previous archive interval (if available). If no earlier entry exists in the archive
memory, the Weatherlink calculates dew point based on the current outside
humidity and the average temperature.
96
TECHNICAL REFERENCE
Weather Data Calculations
Rainfall
In calculating both daily and yearly rainfall totals for the software, the Weatherlink only checks the total rain register on the station. The Weatherlink compares
the current total rain value to the previous total rain entry in the archive memory
to determine the amount of rainfall which occurred during the interval.
▲ Setting or Clearing Total Rain
You must set and clear total rain from the software, not the weather station!
When you set or clear the Total Rain register from the software, the Weatherlink makes an internal note of the change so errors will not occur when calculating daily rainfall for the interval. If, however, you set or clear total rain from
the station, the Weatherlink does not make this internal note and may calculate an inaccurate daily rainfall amount for the interval (often a negative number).
Degree-Days
Because temperature plays an important part in the rate of development of plants
and many pests (especially insects), a measurement which takes into account the
accumulation of heat with passing time is necessary to predict maturation.
Degree-days provide a measure for calculating the effect of temperature on the
development of plants and/or pests. One degree-day is the amount of heat which
accumulates when the temperature remains one degree above the base developmental threshold for 24 hours. One degree-day is also the amount of heat which
accumulates when the temperature remains 24˚ above the base threshold for 1
hour.
Unlike strict time predictions of plant/pest development, degree-day predictions
hold true regardless of location or temperature fluctuations. As long as you know
the number of degree-days necessary for plant/pest development, you may use
degree-days as an accurate predictor. For example, you may know that it takes, in
general, three weeks for a specific pest to develop. What you will find, however, is
that the pest may take 4 weeks to develop in cooler weather and only 2 weeks to
develop in warmer weather. The time prediction can be off by up to a week in this
example, while the degree-day prediction should result in far greater accuracy.
The WeatherLink software uses the outside temperature data in conjunction with
the base and upper thresholds entered for each crop/pest to calculate degreedays. You may choose between three possible methods for calculating degreedays: “cut off,” high/low, or integration. (For a description of these calculation
options, see “Degree-Day Calculation Method” on page 86.)
Chilling Requirement
Certain fruit trees bear best when temperatures drop below specific levels for specific amounts of time during the dormant season. Chilling requirements provide a
measure of this dormancy. For more information, contact your local agricultural
agent or university agricultural extension.

Weather Data Calculations
Soil Temperature Hours
Soil temperature hours may be used to monitor the relative portion of time that
soil temperature is above freezing (or some other threshold) in order to select a
time to plant. For more information, contact your local agricultural agent or university agricultural extension.
Temperature/Humidity Hours
Certain pests (in particular, some molds) develop most aggressively under specific combinations of temperature and humidity. Each pest can be expected to
emerge when a specific number of temperature/humidity hours has accumulated. Temperature/Humidity hours, therefore, can be used to select the optimum
time for application of preventative measures. The use of pesticides can be minimized and, when needed, used more efficiently and effectively. For more information, contact your local agricultural agent or university agricultural extension.
Air Density
Air Density (the weight of 1 cubic foot of air) is an extremely valuable tool for racing enthusiasts, because it helps determine the optimal jetting under current
weather conditions.
Equilibrium Moisture Content (EMC)
Moisture content in wood affects both the size and strength of lumber. If one
knows the EMC of the storage or manufacturing area (which is derived using
temperature and humidity readings), one can also determine the moisture content
of the wood stored there.
Bad Data
Should a sensor get disconnected or malfunction, the software displays any “bad
data” recorded by that sensor as dashes (--). When you create a plot, the software
ignores “bad data,” and skips that point on the plot. You may enter dashes (--)
into the database using the database record editor (see “Edit a Record” on
page 61) to mark bad data points as well.
Note: A dashed wind direction reading does not indicate bad data. See “Wind Direction” on page 95
for an explanation.

Modem String
MODEM STRING
The following sections explain the modem initialization strings used by the software and what each part of the string means. Do not change the initialization
strings unless you understand what impact it will have, otherwise the software
may not be able to work with your fax/modem.
Station Modem Initialization String
The software automatically enters the following modem initialization string,
which should work with most modems: AT E Q V X4 S7=60. The individual components of the string have the following meaning.
▲ AT
This string precedes all Hayes commands.
▲ E
Turns echo off.
▲ Q
Tells the modem to return result codes.
▲ V
Tells the modem to return short form result codes.
▲ X4
Enables result codes 0-7 and 10.
▲ S7=60
Tells modem to wait a maximum of 60 seconds for remote modem to answer
and issue a data carrier.
The software can perform some troubleshooting of modem problems in the form
of error messages. In order for the software to provide error messages, any
modem initialization string you enter must contain the E, Q, and V strings.
Note: If you use another communications program after using the modem with the WeatherLink
Software, you may need to re-initialize the modem using the modem string expected by the
other program.
Auto Fax Modem Initialization String
The software automatically enters the following modem initialization string,
which should work with most fax modems: AT H &D0 E0 V1 &H1. The individual components of the string have the following meaning.
▲ AT
This string precedes all Hayes commands.
▲ H
Hangs up the modem if it is still connected.
▲ &D0
Overrides the default response on the data terminal line (DTR).
▲ E0
Disables command echo.
99
TECHNICAL REFERENCE
Command Line Options
▲ V1
Sets the result code to verbal mode.
▲ &H1
Sets the modem for hardware flow control. Note that not all modems support
hardware flow control.
COMMAND LINE OPTIONS
The following command line options allow you to perform specific program functions as the program loads (such as downloading, clearing highs/lows, or opening a specific station. In order to use a command line option, open the Properties
dialog box for the program icon (consult your Windows documentation for
instructions) and enter the command line options after PCLINK.EXE.
▲ Station Directory -o
If you have multiple stations, when the software loads, it also opens the station in the station directory specified.
▲ Station Directory -d
When the software loads, it will automatically download data from the station
in the station directory specified.
▲ Station Directory -c
When the software loads, it will automatically clear data from the station in
the station directory specified. If you have only one station, you do not need to
specify the station directory.
▲ Station Directory -p
Some printers can not print the plot axis labels vertically. We have seen this
on a HP IIP printer at 150 dpi. If you have a printer that is doing this, you can
use this command line option to force the printer to print the axis labels out so
you can read them. This applies to Plots and Strip Charts.
Examples:
▲ PCLINK.EXE Official -o
After loading the software, opens the station contained in the sub-directory
entitled “Official.”
▲ PCLINK.EXE Official -d -c
After loading the software, downloads and clears information from the station
contained in the sub-directory entitled “Official.”

Importing WeatherLink Data into Other Programs
IMPORTING WEATHERLINK DATA INTO OTHER PROGRAMS
When you create an export file (see “Export Records” on page 63) the software
creates a tab delimited text file. All that means is that the software creates a text
file which places each record on a separate row and inserts a tab between each
piece of data in that row. If you open the file in a text editor, it will look like this:
TAB DELIMITED EXPORT FILE
Most popular spreadsheet and database packages have the ability to open or
import tab delimited text files while maintaining the structure of the original
database. Consult your program’s documentation for instructions on importing
tab delimited text files. You may also open or import the file in most popular
word processor programs as a text file. Because the data columns are separated by
tabs, you may generally choose any desired font.
LEAP YEAR CORRECTION
The weather stations which work with the WeatherLink software do not read February 29 (Leap Day). Therefore, you will need to correct your database during a
leap year. The most important thing to remember is this: do not change the date
on the weather station from the station itself. Instead, follow one of the two procedures below, depending on whether or not your computer keeps track of leap
years (which you can determine by checking the date on your computer after February 29 to see if it has the correct date).
When you are within one week of February 29th in a leap year, the program will
automatically open a help file which informs you of the procedure for correcting
data in a leap year whenever you load the software.
Computer Keeps Track of Leap Years
If your computer keeps track of leap year itself, all you need to do is download on
or after February 29. The program will prompt you to confirm that you want to
correct data as it writes it to your database. Choose Yes to correct the data. When
finished, use the Set Time command to set the station to the correct date.
101
TECHNICAL REFERENCE
Backing Up and Restoring Data
Computer Does Not Keep Track of Leap Years
If your computer does not keep track of leap year itself, follow the procedure
below.
1. DO NOT DOWNLOAD DATA ON FEBRUARY 29.
Both your computer and weather station should read March 1.
2. Anytime after 2-29 you should set the correct date on your PC.
You should use the Window’s Time and Date control panel. Do not set the stations time and date at this time.
3. Download your data from the software.
The software will prompt you to indicate whether you want to correct data for
the leap year.
4. Choose Yes.
The software corrects data as it writes it to your database.
5. Set the correct date on your weather station from the software.
Be sure to clear your archive memory when given the option.
BACKING UP AND RESTORING DATA
Weather data is backed up and restored by dragging and dropping the pertinent
files via File Manager ( Windows 3.1x ) or Windows Explorer ( Win95 ). You may
back up files to a floppy disk, a separate hard disk backup folder, or both.
Note: For information on using File Manager or Windows Explorer, consult your Windows documentation.
Comprehensive Backup
Drag the entire subdirectory folder named after your database to the desired
floppy disk or hard disk backup folder.
Individual Month Backup
Individual months of data are located in the database subdirectory and have the
following format: YYYY-MM with a three letter file extension (the first three lettersof your station name). For example, weather data from a station called “Home”
from January 1997 will be in a file named 1997-01.HOM. (See “Database Files” on
page 94 for more information.)
To backup data from an individual month simply drag the file corresponding to
the desired month(s) to the desired floppy drive or hard disk backup folder.
Restoring Data
Drag and drop the desired file(s) from your floppy disk/backup folder into the
proper folder (the station directory) in the PCLINK4 directory. See “Station Directory” on page 93 for more details.
Alternatively, you may drag and drop the entire station folder from the floppy
disk/backup folder to the PCLINK4 program directory (overwrite all existing
files). Only do this if you are sure the data files on the backup disk/folder are current and
correct.

6 TROUBLESHOOTING GUIDE
The following section answers some of the most commonly asked questions about
the WeatherLink Software. Please consult this guide before contacting Customer
Support (510-732-7814). If your problem is not urgent, send us a description via
e-mail (support@davisnet.com) or fax (510-732-9188). You can also check our web
site (www.davisnet.com/support/) for FAQ’s, troubleshooting information, and
a link to tech support.
COMMUNICATIONS PROBLEMS
?
Why can't the WeatherLink Software “communicate” with the WeatherLink?
If you are experiencing difficulty establishing communication between the
weather station and the WeatherLink Software, start by checking the weather
station's own diagnostics. To do this, you must remove all power to the
weather station and then restart the weather station by restoring power (with
the WeatherLink still attached). You should hear three beeps, each of which
occurs when the weather station passes one of its diagnostic tests. The first
beep occurs after approximately one second, the second after approximately 8
seconds, and the third after approximately 22 seconds. If you do not hear one
or more of these beeps, contact Davis Instruments at 510-732-7814.
If you hear all three beeps, see “Finding the Correct Serial Port” on page 12 for
instructions on checking you standard serial ports. If this identifies a serial
port other than the one you selected in station setup, try connecting to the
WeatherLink again.
If you still cannot connect or if the loopback test identifies the serial port you
already have selected, attempt to eliminate the following possibilities. If you
have questions on how to proceed, it is recommended that you contact your
PC vendor or PC technical support.
▲ You have a hardware device conflict.
▲ Your serial port uses a non-standard IRQ line.
▲ Your serial port is defective.
▲ The loopback connector or the WeatherLink adapter plug is bad.
?
How do I select the correct serial port?
If you can use the serial port in question with another program, simply determine the serial port to which that program is set. Otherwise, see “Finding the
Correct Serial Port” on page 12 for instructions.
PROGRAM PROBLEMS
?
Why are the readings on my station and the WeatherLink Software different?
The calibration numbers for the weather station and software may not agree.
Make sure you set all calibration numbers from the software. See “Calibration
Numbers” on page 93 for further explanation.
103
TROUBLESHOOTING GUIDE
Program Problems
?
The barometer graph on the bulletin does not “fill in” completely. Why?
When you first load the bulletin, the only case in which the barometer graph
will fill in completely is when you have data in your database for the span of
the barometer graph (that is, the past six hours). Make sure of the following:
▲ There is data in your database for the span of the barometer graph.
▲ The time and date of the stored barometer data is correct in your database.
▲ The time and date on the PC is correct.
▲ The time and date on the weather station are correct.
?
Why do I get strange daily rainfall readings?
Make sure you set total rainfall from the software (see “Set Total Rain” on
page 27). If you change the total rainfall from the weather station, it is very
likely that you will create an odd daily rainfall amount for the interval during
which you make the change. (see “Rainfall” on page 97.)
?
I have duplicate records in my database. Why?
If you do not download prior to changing the weather station’s time and date
(for a Daylight Savings time change, for example), you may get duplicate
records. Make sure to download before setting time and date. In addition, you
should be aware that the midnight records are duplicated so they appear in
each consecutive day. For example, a midnight record would appear at the
end of the data for November 22 and at the start of the data for November 23.
Using the record editor (see “Edit a Record” on page 61) to change the record
in one day does not change the record in the other day.
?
No wind direction reading (or dashes instead of a reading) appears in my database.
First, make certain that you did not select a Weather Wizard II-S or Perception
(neither of which have wind direction) in your station setup (see “Station Config” on page 19). Otherwise, you should simply be aware that if there is no
wind speed when the direction is being sampled, wind direction is not
recorded. During intervals with very little wind speed, no direction may be
recorded.
Note: Since high wind speed is sampled more often, it is possible to have a high wind speed
but no wind speed or direction.
?
104
My archive memory is empty and I know it should not be. What can I do?
First try using “Set Archive Interval” (page 24) to clear the archive memory
and see if this corrects the problem. You will lose any undownloaded data in
your archive memory, but all of you calibration numbers and alarm settings
will remain intact. If this doesn’t work, “reboot” your weather station (that is,
remove all power and restart the station). All data which has not been downloaded will be lost. You will also have to reset all settings (barometer, calibration numbers, etc.).
TROUBLESHOOTING GUIDE
AutoFax Troubleshooting
?
After successfully downloading, the data does not appear to be in my database. Where
is it?
The most distinct possibility in this case is that the time and date on your
weather station are incorrect (this can often happen if you have a power outage and forget to reset the time and date on the weather station) and therefore
the data was written into the wrong month, day, and/or time. Correctly set
the time and date on your weather station (see “Set Time” on page 23) and all
future data should download correctly.
It is also possible, if you have multiple stations, that you downloaded data
into the wrong station’s database. Make sure the desired station is open before
downloading.
?
When viewing data, dashes appear in place of a value for functions other than wind
direction. Why?
If no data was recorded by a sensor (for example, the sensor was disconnected) or if bad data was recorded for a sensor (for example, the sensor was
malfunctioning), the software dashes out the entry rather than showing
invalid data. You may use the record editor (see “Edit a Record” on page 61) to
correct these entries.
AUTOFAX TROUBLESHOOTING
?
The software is not finding the fax. Why?
Make sure your modem is configured to use COM port 1, 2, 3, or 4. If not, free
one of those COM ports and reconfigure the modem to use it.
If you have installed a modem using Windows 95's Modem Installation Wizard and it has automatically assigned it a COM port of 5 or higher, use the
modem's installation disk to configure the modem. Do not run the Modem
Installation Wizard in the control panel; Windows 95 will add the modem by
itself without allowing you to set the COM port.
?
What “class” should I use?
If your fax modem does not support Class 1, 2, or 2.0 you will not be able to
use the automatic fax feature. You will need to obtain a fax modem which
does support one of these classes. Consult your fax modem’s documentation
to be sure it supports the necessary classes.
Every modem is different (in terms of timing, fax capability, error checking,
etc.). First try faxing using the Class 2 or 2.0 setting if your modem supports it
(most newer modems do). Modems set to these classes will work better with
the Multiple Page option selected.
Note: Some US Robotics modems with defective Class 2.0 chips will not work when Class 2.0 is
selected. Change the setting to Class 1.
If your fax modem has only Class 1 capability (or if you have a slow PC) try
changing the Windows' communication driver. (Sometimes Windows' communication driver is not fast enough and a single page comes out, but the fax
machine times out and does not send appropriate "end of page" signals to the
computer). See “Changing Windows Communications Driver” on page 106
for instructions.
105
TROUBLESHOOTING GUIDE
AutoFax Troubleshooting
Changing Windows Communications Driver
The WFXCOMM.DRV (supplied on the install disk) significantly improves AutoFax performance over the default Windows driver (COMM.DRV) on many systems. This driver tends to produce more readable reports (each record is the same
height), and tends to work more reliably in multiple page mode. If your problem
is one of “readability” or if the multiple page option is not working, install the
WFXCOMM.DRV driver as explained below.
Note: This driver works with other 16 bit serial port applications. It is an improved communications
driver written by someone other than Microsoft.
1. Copy WFXCOMM.DRV from the installation disk to your Windows directory.
The file is also available on the web at: www.kiae.su:8090/kiarchive/windows/drivers/.
2. Edit the "system.ini" file (section: [boot]; line: comm.drv) to read:
comm.drv=wfxcomm.drv.
This line will typically read comm.drv=comm.drv initially. Consult your Windows' documentation for instructions on changing the system.ini file.
3. Reboot your system to make sure the change takes effect.
