Welcome to Davis Instruments’ GroWeatherLink Software. The WeatherLink and
software allows you to connect your personal computer to GroWeather™ stations
to store, view, plot, export, and print the weather data gathered by the station.
C
ONTENTS OF PACKAGE
Before proceeding, please check to make sure your GroWeatherLink package contains the following:
▲
PC COM Port Adapter
The PC COM port adapter is a 9-pin connector with an RJ connector jack in
one end. Use the PC COM port adapter to connect the WeatherLink to a 9-pin
serial port.
▲
40 feet (12 m) WeatherLink Cable (4-conductor
)
▲
WeatherLink Isolator Unit
The isolator unit provides upgraded protection against the electrical disturbances caused by ground offsets or static charges by placing an optical connection between the WeatherLink and your computer. Since electrical
disturbances cannot travel across the optical connection, the isolator unit will
help prevent lockups of the station console and possible damage to the console, WeatherLink, and PC.
▲ Loopback connector
The loopback connector is a short piece of wire with a cable plug at one end
and a red plastic cap at the other. The loopback connector can be used to determine what serial ports are available for the WeatherLink (see “Finding the
Correct Serial Port” on page 23).

ARDWARE INSTALLATION
There are three basic types of installations: direct connection, phone modem connection, and radio multi-point connection.
▲
Direct connection
Involves connecting the GroWeatherLink/ET Data Logger (simply referred to
as “WeatherLink”) directly to your computer. Direct connections include
installations that use Davis’ Short-Range Modem Pair (#7875) and/or a base
and station (i.e., single-point) radio.
▲
Phone modem connection
Refers specifically to any installation where the WeatherLink is connected to a
telephone modem and a second modem is connected to your computer.
▲
Radio multi-point connection
Refers to installations where more than one station transmits WeatherLink
data to your computer via radio modem.
Note:
If you have not yet purchased a remote communications device—such as a telephone or
radio modem—and you would like to know more about the various options, contact our
tech support team (at 510-732-7814) and ask for the “WeatherLink Radio Communications” application note.
H
ARDWARE REQUIREMENTS
The required hardwar e dif fers depending on whether you are attempting to make
a direct connection, phone modem connection, or radio multi-point connection.
Direct Connection Hardware Requirements
In addition to the provided hardware, check that you have the following items.
▲
GroWeatherLink/ET Data Logger
▲
Computer running Windows™ 3.1, NT, or 95 with at least 5 MB of free disk space, 4MB
of RAM, and one free serial port
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 64K 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 1.92 MB/month
while the data stored at a 2 hour interval requires approximately 16K/month.
▲
Short-Range Modem Pair (SRM)—optional
For transmitting data over twisted-pair cable at a distance of up to seven miles
(11 km). SRM (#7875) and twisted pair cable (#7884) available from Davis.
▲
Radio—optional
You may use a third-party radio to transmit data from the WeatherLink to the
PC or SRM. Davis offers an installation kit for two such radios (see “Radio
Multi-Point Connection” on page 9 for more information). May also require
Alarm Output Module to conserve power.

Use the label sheets provided with your GroWeather to mark your WeatherLink
cables before you begin installation. Make sure you label every cable end, includ-
ing extension cables. Doing this now will help prevent confusion during the
installation and if you ever need to disconnect a cable at a later date.
▲
Place the C3/LINK label on the end of the short cable coming from the WeatherLink.
▲
Place the LINK/L1 label on the end of the long cable coming from the WeatherLink.
▲
Place a L2/LINK to PC/PC label on each end of the 40-foot (12-m) WeatherLink cable.
This cable runs from the isolator unit to the computer or external modem. On
one end of the cable, orient the label so L2 is closest to the end of the cable. On
the other end, orient the label so PC is closest to the end of the cable.

Direct Connection Installation
1. If the station has been operating for some time and/or you have changed the default
settings, make a note of the barometric pressure, total rainfall, and (if applicable) calibration numbers.
You must remove power from the station to install the WeatherLink, which
will cause these values to be erased. Use the software to reenter these values
after restoring power to the station.
2. Remove the mounting base from the station and remove all power from the station by
removing the AC-power adapter and battery backup.
Failure to remove power to the weather station before installing the WeatherLink may cause damage to the WeatherLink or station.
3. Insert the cable plug at the end of the short cable coming from the WeatherLink into
the jack marked C3 (To LINK) on the bottom of the console.
4. Restore power to the weather station by reattaching the power adapter and battery
backup.
The weather station should beep three times. The third beep, which should
occur within 30 seconds, indicates that the WeatherLink is operating correctly.
5. To identify which link revision you have, look at the label on the back of the WeatherLink and write down the first two letters of the manufacturing code.
If the first two letters are “LD,” you have revision D. If the first two letters are
“LE,” you have revision E. The Rev. E W eatherLink has been enhanced for use
with radio connections.

Phone Modem Installation Instructions
Before installing the WeatherLink for a phone modem connection, you need to
install and configure a modem for use with your computer (according to the
instructions supplied by the manufacturer). Make a note of the COM port and
IRQ used by the modem. You will need this information when entering serial port
settings for the station (see “Serial Port” on page 32).
1. If the station has been operating for some time and/or you have changed the default
settings, make a note of the barometric pressure, total rainfall, and (if applicable) calibration numbers.
You must remove power from the station to install the WeatherLink, which
will cause these values to be erased. Use the software to reenter these values
after restoring power to the station.
2. Remove the mounting base from the station and remove all power from the station by
removing the AC-power adapter and battery backup.
Failure to remove power to the weather station before installing the WeatherLink may cause damage to the WeatherLink or station.
3. Insert the cable plug at the end of the short cable coming from the WeatherLink into
the jack marked C3 (To LINK) on the bottom of the console.
4. Insert the cable plug at the end of the long cable coming from the WeatherLink into the
jack marked L1 (To LINK) on the isolator unit.
5. Insert the cable plug at one end of the 40-foot WeatherLink cable into the jack
marked L2 (To PC) on the isolator unit. Use the cable plug on the end of the cable where
the L2 side of the cable label is closest to the cable’s end.
6. Insert the cable plug at the other end of the 40-foot WeatherLink cable into the jack
marked PC on the PHONE MODEM adapter. Use the cable plug on the end of the cable
where the PC side of the cable label is closest to the cable’s end.
This connection totals 48 feet (14.5 m) which is the maximum connection distance you may have without using Davis’ SRM.
7. Connect the PHONE MODEM adapter to the external modem.
8. Connect the external modem to an available phone jack.
9. Turn the modem on.
The modem must be on before you restore power to the weather station.
10. Restore power to the weather station by reattaching the power adapter and battery
backup.
The weather station should beep three times. The third beep, which should
occur within 30 seconds, indicates that the WeatherLink is operating correctly.

A Few Notes About Phone Modem Connections
If you indicate a phone modem connection when setting up your station (see
“Serial Port” on page 32), the software automatically dials the station (using the
phone number you provided) whenever you attempt to initiate a program action
which requires the software to “talk” to the WeatherLink.
Note:
The software dials the station only after you choose Ok or Yes to initiate a program action. If
you do not wish to connect, press Esc before you are actually connected.
While connected to a phone modem station, the software displays your on-line
time in the main program window’s title bar. Once connected, the software will
remain “on line” with the phone modem station until you choose to hang up. The
software remains “on line” whether or not you are doing something which
requires it to be connected.
Hanging Up
1. Choose Hang Up.
The software prompts you to confirm that you want to hang up.
2. Choose Yes.
The software hangs up the modem and closes the On Line window.

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 saved on your har d
disk rather than from the station itself. Therefore, you must set station values
from the software. If you set station values from the station itself, the readings
you see in the bulletin, database, and plots may not agree with your station’s
readings.
About the Walkthrough
The software includes a station setup walkthrough which steps you through the
entire station configuration procedure. After adding a new station, the software
automatically prompts you to indicate whether or not you want to be walked

Merge Data
To fill in missing weather data, you can supplement one weather station’s data
with another. The database you want to supplement is called the original database; the database that provides the missing data is called the source database.
Before merging the databases, keep in mind the following tips and suggestions:
▲
Make sure you have enough space on the disk containing the Windows Temp directory to hold a file with the combined size of the original and source databases.
The operation creates a new data file in the Windows Temp directory that is
erased once the merge operation is complete.
▲
Best results are obtained if the original files and the source files have the same
archive interval.
If the archive intervals are different, try to merge the file with the longer
archive interval into the one with the shorter interval. For example, if one
database has 15-minute intervals and another has 30, open the station with the
15-minute interval and merge the 30-minute interval files into it. This way the
shorter interval database will not add twice as many, possibly conflicting, data
points.
U
SING
THE
S
OFTWARE
File Menu
29
▲
To compare databases archived on separate computers, copy the station configuration file, as well as the source files, from the source database.
See “Database Organization” on page 97 for details on the station configuration and source files.
▲
The data merge does not change the time or data of merged data.
This means that it can not solve the problem of weather stations that have
been re-powered and thereby had their dates reset to January 1.
▲
Differences in calibration numbers or settings are not taken into account.
▲
Data notes in the source file are not copied into the merged data file.
▲
After the merge, it is important to check the data (paying special attention to the
barometer readings).
Always examine merge results critically after performing a data merge. Use
the “Edit a Record” feature (page 79) to fine tune the data as needed. If you are
not satisfied with the results of the merge, you can restore the original,
unmerged data file by deleting the merged data file and renaming the backup
file to the original three-letter extension.
Note:
Only one backup file is made. If you perform multiple merge operations on the same file,
only the results of the last merge can be undone.
Follow the steps below to merge a source data files with original data files:
1. Open the original database - the database with missing data.
2. Choose File Merge from the File menu.
A Merge Data dialog box appears.
3. Select the data file(s) that contain the data that you want to add to the original data-
base.
You can access data files in any directory on your system, but you can only
add files from one directory at a time. The data files are found in the station
directory and will have a name of the form "yyyy-mm.ext" where "yyyy" is the
four digit year , "mm" is the two digit month, and "ext" is the station extension,

Barometer
The station’s built-in barometer is only really accurate between 50˚F and
90˚F (10˚C to 32˚C). The software will display the barometer graph on the
bulletin or the summary. Installations in which the console is located outside may encounter inaccurate barometer readings when outside of this
temperature range. If you experience this problem and if the inaccurate
readings bother you, turn this option off.
▲
Latitude and Longitude
Enter your latitude and longitude. The software uses latitude and longitude when determining net radiation which is used in the calculation of
Evapotranspiration.
Note:
If you do not enter latitude and/or longitude, the software will use the ET calculated
by the console, which is not as precise as the software.
▲
Time Zone
Select the time zone in which the station is located from the drop-down list
box. The software uses the station’s time zone when determining net radiation which is used in the calculation of Evapotranspiration.
▲
Daylight Savings Time
If you are currently on Daylight Savings Time, select this option. The software uses Daylight Savings Time information when determining net radiation which is used in the calculation of Evapotranspiration.

The software is capable of automatically creating a text file (“download.txt”) which contains all downloaded records for the last 2 days (the
day on which you downloaded and the previous day) after each download.
▲
Clear archive memory after download
Data is stored in the WeatherLink’s archive memory (see “Archive Memory” on page 95) until you clear it. You may decide to have the software
automatically clear the archive memory whenever it downloads data by
selecting this option. Clearing after each download will decrease the time
it takes to download because there will be less “accumulated” data in the
archive memory. Not clearing after each download allows you to store
data into multiple databases (if more than one person uses a single
weather station, for example) by downloading the archive memory more
than once.

B
ULLETIN
The bulletin gives you a graphic representation of the current reading and the
numeric reading for each condition. For all bar graphs (air temperature, for example), highs and lows are represented by yellow lines which appear above the bar
(high) or within the bar (low). As long as the bulletin is running, the software
automatically updates highs and lows as they occur.
When you first start the bulletin, 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 “get” all of the 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. If you do not download highs and lows, the
highs and lows on the bulletin screen will only reflect the highs and lows
recorded while the bulletin is running.
The bulletin displays a line graph of barometric pressure over the past six hours
(unless you have turned of the barometer in “Station Config” on page 30). When
you first open the bulletin, the software graphs the current barometric pressure
and any barometric pressure data which exists in your database for the past six
hours. (For example, if no barometric pressure data for the past six hours exists in
the database, the software will only plot a single point which represents the current barometric pressure. If data exists for only a portion of the six hours, the software plots whatever data it has available in the database.) While the bulletin is
running, the software plots another point on this graph every 15 minutes.

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. The strip charts can be set to
update automatically which allows you to view changing weather conditions in
real time.
S
TRIP CHART WINDOW
Strip Chart Basics
Whenever you open the strip chart window, the software automatically downloads data (if necessary) to make sure it has the most current data for the chart.
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. You may select
whatever variables (weather conditions) you want plotted onto the four charts,
though each chart may display the axis information for only one of the variables.
In the strip chart shown above, for example, both rain and barometric pressure
are plotted on the bottom strip chart, though the axis button only says Rain and
the axis shows the scale for the rainfall graph. You may also select the desired plot
span to determine how much data you are viewing at any one time.
▲ 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 graphs at each archive interval) until you select to view historical data on the strip charts (see “View Historical Data” below) at which point
it is automatically taken out of auto update mode. To return to auto update
mode, choose Auto Update from the Options menu. If necessary, the software
will download any data in the archive memory and will move to the most current date in the database.

K Factors
Crop-specific K factors allow you to calculate more accurate
evapotranspiration amounts by taking into account the different
transpiration rates of different crops and at different stages of
development. When K factors are used to calculate evapotranspiration, it is referred to as ETc. The software will automatically calculate ETc using the K factors you enter and the ETo information
calculated by the station.
The software allows you to enter different K factors for different stages of crop
development. ETc for each day is calculated using the appropriate K factor. For
example, if you enter a K factor of 1.0 for 4-1-96 and a K factor of 1.25 for 4-15-96,
the software uses the 1.0 K factor in calculating ETc for 4-1-96 through 4-14-96
(inclusive). For 4-15-96 and all subsequent dates (until a new K factor is entered
for a date after 4-15-96), the software uses the 1.25 K factor in calculating ETc.
▲ Add K Factor
To add a K factor, click on the K Factor button and choose Add K Factor from
the pop-up menu. The software prompts you to enter an date and K factor.
Enter the appropriate information and choose OK. The software adds the K

▲ 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 deter mining 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.
