Station Setup
Each station connected to the computer must have its own station within the
software. The software creates a database for the station and other station-specific information, and provides the necessary communication settings (serial
port, baud rate, etc.).
Adding a Station
1. Select New Station from the File menu. The New Station dialog box
displays.
2. Type the desired station name (up to 40 characters/spaces) into the Station
Name text box. The software uses the first eight characters of the station
name (not counting spaces or punctuation marks) as the name of the directory where it saves this station’s database and configuration files. The first
eight characters of each station name must, therefore, be unique.
3. Click OK to save the new station or click Cancel to exit without saving.
The software saves the new station, creates a directory and a configuration
file for the station, and prompts you to enter the walk-through procedure.
About the Walkthrough
The software includes a station setup walkthrough that steps you through the
weather station configuration procedures. After adding a new station, the
Walkthrough dialog box automatically displays. By selecting Yes, the
walkthrough begins. By selecting No, the Walkthrough is cancelled. You can

Updating Previous Versions
Starting with Version 5.2, WeatherLink stores additional sensor data in the
weather database. Data files from earlier releases do not contain the additional
data and should be converted before use by the latest version of WeatherLink.
The following procedure explains how to convert older WeatherLink data files
for use with WeatherLink 5.2 and later versions. If you are updating from version 5.0 or 5.1, there are also instructions on how to retrieve additional existing data from your Vantage Pro data logger and incorporate it with your
weather data files.
Database Conversion
If you have an existing weather database from WeatherLink 5.1 or earlier
(including versions of WeatherLink 3 and 4), there are two ways to convert
those files for use with versions of WeatherLink 5.2 or later.
Convert a WeatherLink Station
This method converts all the data files in an existing WeatherLink station
directory and retains the previously entered station configuration data.
1. Install the new version of WeatherLink in a new program folder.
2. Copy the station folder from the previous WeatherLink program folder to a
WeatherLink 5.2 or later program folder.
3. Use the Open Station command in the File Menu to open the copied station
folder. WeatherLink automatically detects that the station was created by a
previous version of the software and asks to convert the data and station.
4. Click OK to convert the station configuration, including the weather data
files. WeatherLink automatically creates a backup copy of the old files and
then converts them for use by versions of WeatherLink 5.2 or later.
Import Data Files
The Import Database Files menu option allows you to select individual files or
groups of files to be converted for use by WeatherLink 5.2 or later.
14
Database Conversion
Note: WeatherLink does not import database files created by versions of WeatherLink 5.2 or
later using the Import Database File option. The Import Database Files option imports
only database files created by WeatherLink version 5.1 or earlier. To import data files from
WeatherLink 5.2 to 5.4, copy the .wlk file directly into your weather station directory.
1. Open WeatherLink 5.2 or later and select Import Database Files from the
File menu. The Browse dialog box displays.
2. Select the data files you want to import. Select one file or multiple files in
the same folder.
3. Click Open to convert the selected files. These files are put into a subdirectory called "Converted Database Files".
4. Copy the converted files to your station directory.
5. Reopen the station in WeatherLink to view the converted files.
Retrieving Data From the Data Logger
The data loggers for Vantage Pro, Vantage Pro2, and Weather Envoy contain
data and weather variables that were not used by WeatherLink 5.0 or 5.1, such
as UV, solar radiation, rain rate, and ET (evapotranspiration). Versions of
WeatherLink 5.2 or later allow you to view and use these variables that earlier
versions did not. Depending on the archive interval used on your data logger,
up to 200 days of this data which you can retrieve and incorporate into a version of WeatherLink 5.2 or later, may be stored on the data logger.
To incorporate this data into WeatherLink 5.2 or later data files:
1. Select New Station in the File menu and create a temporary weather
station folder. (See Adding a New Station for more information)
2. Select Download in the File menu or click on the Download icon. WeatherLink does a full download of all data stored in the data logger.
3. Select Browse in the Window menu or click on the Browse icon.
4. Scroll to the beginning of the data file, and write down the time and date of
the first entry in the database.
5. Open the original WeatherLink station using the Open Station option in the
File menu.
6. Select Browse from the Window menu or click on the Browse icon.
7. Select Delete Records in the Browse Menu.
8. Select records for the days following the earliest date in the temporary station database.
Note: Do not select the records for the day the temporary database begins. Each record can be
deleted individually for that day in the next step.
15
Updating USB Drivers
9. Individually select and delete each record in the data base that is dated
after the earliest record in your temporary database from the Browse Window.
Note: WeatherLink downloads data only for dates and times not already in the database. Deleting records allows it to download new data.
10. Select Download in the File menu or click on the Download icon to download data from the data logger.
11. Select Delete Station in the File menu and select the temporary station you
created in Step 1 to delete it from the list of stations currently in use.

Troubleshooting Guide
The following section answers some of the most commonly asked questions
about WeatherLink. Please consult this guide and the online help files before
contacting Technical Support.
Communications Problems
V Why can’t WeatherLink communicate with the data logger and station?
If you are having trouble establishing communication between the weather
station and WeatherLink, start by checking the console's own diagnostics.
Remove all power to the console and restart it by restoring power (with the
data logger still attached).
Note: The data logger uses nonvolatile memory, so any previously recorded data is still stored.
However, put the console in Setup Mode (by pressing and holding DONE, then pressing
the down arrow(-)) before removing power, so that no damage to the data logger occurs.
• Three beeps sound from the console, each of which occurs when the
weather station passes one of its diagnostic tests. Each beep follows the
previous after about one second. The first beep notes that the processor is
running. The second beep emits when the data logger is detected (if
installed) and the third beeps for the display. If using a Weather Envoy, two
beeps emit when it passes the first two diagnostic tests.
Note: If you do not hear one or more of these beeps, contact Davis Instruments. Only two
beeps emit if the data logger is not installed.
• If the console sends three beeps or the Weather Envoy sends two beeps, See
“Communication Port Settings” on page 13 for instructions on checking
standard port settings. If the port settings or the loop back test process identifies a serial port other than the one selected in station setup, try connecting to the data logger again.
• Check the serial port adapter if using a serial port connection. Use only the
blue serial port adapter supplied with WeatherLink. Older models, or models not supplied in the WeatherLink connection kit, are not compatible.
17
Communications Problems
• Check the Baud Rate setting on the console and in the Communication
Port dialog box in the software. Make sure they have the same number.
Enter the console’s Setup Mode by pressing and holding DONE and then
pressing the down arrow (-) on the console.
• Scroll through the setup choices by pressing BAR until you reach the Baud
Rate screen. This screen appears only if the data logger is plugged into the
console.
• Test the serial port using the provided loopback connector. Use the Loopback button (as opposed to the Test button) in the Communications Port
dialog box to test and find the correct serial port connection. If a communications problem exists, it determines whether the serial port or the data logger is not communicating properly. The loopback function also detects and
reports the presence of any modems.
Use the loopback connector (the short cable with a
phone jack on one end and a red plastic tip on the
other) supplied with a WeatherLink serial port conLoopback
nection package.
connector
1. If necessary, disconnect the cable between your
console and the adapter connected to the COM port.
2. Insert the loopback connector into the adapter.
3. Select Communications Port from the Setup menu. The Communications
Port dialog box displays.

Program Problems
4. Click Loopback.
The software searches all standard ports and displays the COM port number where the loopback connector is located.
The correct COM port is automatically selected in the Communications
Port dialog box. If the loopback connector is not found on any COM port,
your serial port may not be working. If a connection does still not exist or
if the loopback test identifies the same serial port you have selected, eliminate the following possibilities:
Note: Contact your PC vendor or technical support for more information on these device difficulties.
• Hardware device conflict—Check the Device Manager tab in the Windows System Properties dialog box to ensure that Windows recognizes
the selected COM port. Consult your computer’s documentation to see how
to access the System Properties dialog box.
• The communication port uses a nonstandard device name—WeatherLink recognizes serial ports named COM1 through COM10 only. To use a
modem, specify the underlying COM port on your PC. To find out which
port the modem’s connected to, display Windows’ System Properties >
Device Manager > “modem name” Properties > Modem > Port, and check
the listed “modem name” is the modem name you installed.
• Your serial port is defective.
• The loopback connector or the WeatherLink adapter plug is bad.
Program Problems
V The barometer graph on the Bulletin does not “fill in” completely.
When you first load the bulletin, the barometer graph will only fill in completely when you have data in your database for the last 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.
In the Station Configuration dialog box, set the Download archive data
when Bulletin or Summary is started drop-down box to Always or to
Confirm each time.

Program Problems
V No wind direction reading (or dashes instead of a reading) appears in my database.
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: Because high wind speed is sampled more often, it is possible to have a high wind speed
but no wind speed or direction.
V WeatherLink says “No new data to download” but I know there’s data there. What can
I do?
The Vantage Pro2 system is smart enough to send only data it hasn’t already
sent to the computer. So, when you initiate a new download, the program will
retrieve the first record after the last record shown in the WeatherLink’s
Browse Window. Older data is stored in the logger as a backup. To see how
many of these backup records are stored in the logger, create a new station and
download the data into this new database. Because there are no records stored
in the station you just created, WeatherLink will download everything it has
stored.
Next, try clearing the archive memory using the clear dialog box. You will lose
any data not already downloaded in your archive memory, but all of your calibration numbers and alarm settings will remain intact. If this doesn’t work,
reboot your weather station (that is, remove and then restore all power to the
station).
Note: Make sure to put the console in Setup Mode (by pressing the DONE and DOWN arrow
keys) before removing the batteries. The ensures the station will remember the current
daily high and low values and the daily rain and ET accumulation.
V 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 radio interference blocked reception), 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 can use the record editor to correct
these entries.
V The data I want to see, such as solar radiation, soil moisture, or Temp 2 is missing completely or is greyed-out?
All optional sensors must be enabled in the Station Configuration setup dialog
box before the data will be displayed in WeatherLink. If you are not seeing
data from a sensor that is installed in your weather station, be sure check the
Station Configuration in the Setup Menu and make sure the sensor has been
selected.
