Required Accessories
You will need to install a third-party serial port adapter on your Macintosh com-
puter in order to run WeatherLink for Mac OS X. The Keyspan USB Twin Serial
adapter has been tested with WeatherLink, but other serial adapters should also
work:
• USB-to-serial port adapter
Optional Accessories
The following optional accessories, designed for use with WeatherLink, are avail-
able from your dealer or may be ordered directly from Davis.
• Telephone Modem Adapter
Connects the data logger to a modem.
• Use adapter #6533 with Vantage Pro Stations.
• Use adapter #7870 with Wizard III, Monitor II, and Perception II stations.
• Standard 4-Conductor Extension Cable
Use one 40’ (12 m) extension cable (#7876-040) to extend the distance between
your station and the computer. (48’ (14.4 m) maximum)
Hardware Installation
You can connect a computer directly to your weather station using the Weather-
Link data logger (local connection), or you can connect a computer to a remote
weather station using a phone modem (remote connection). Requirements and
installation for each type of connection differ, and are explained separately below.
Hardware Requirements
The hardware requirements for local and remote connections are listed below.
Local Connection Hardware Requirements
In addition to the provided hardware, the following are required for a direct con-
nection.
• Macintosh computer running OS X v10.01 or newer with at least 5 MB of free
disk space
The amount of space necessary for the data files depends on the archive inter-
val. 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.
• A serial port adapter connected to a Macintosh USB port.

A Few Notes About Phone Modem Connections
If you indicate a phone modem connection when setting up your station, the soft-
ware automatically dials the station whenever you initiate a program action that
requires the software to talk to the station.
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
By default, WeatherLink will hang up the connection to the modem after one
minute without any communication with the station. Use the Serial Port dialog
box in the Setup menu of WeatherLink to change this default value. (See the
WeatherLink help files for more on this subject.)
Note: WeatherLink will not hang up the phone line ifthe Bulletin or Summary windows are
active.
Software Installation and Setup
This chapter covers software installation and setup.
Installing the Software
1. Place the Install Disk in your CD ROM drive.
2. Copy “install.sit” from the CD to your desktop and open it. The installation
software will automatically extract itself.
3. Run “install”.
4. Follow the on-screen prompts to complete the installation.
Running the Software
To run the software, double-click on the WeatherLink 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 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.

Station Setup
To interact with your station, you must add your station to WeatherLink’s database,
which means naming the station, configuring the software to work with that station
and with your computer hardware, and setting station values such as time, baro-
metric pressure, total rainfall, and calibration numbers.
Adding a Station
1. Choose New Station from the File menu.
The software opens the Add New Station dialog box.
2. Type the station name into the text box.
The station name may be up to 40 characters/spaces long. Note that the soft-
ware 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 sta-
tion’s database and configuration files. The first eight characters of each sta-
tion 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 walk-
through procedure.
About the Walkthrough
Weatherlink includes a Walkthrough option that steps you through the station
configuration procedure. After adding a new station, the software automatically
asks if you want to use Walkthrough to set up your station. You can, 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 that lets
you begin this set of procedures at any time.
Note: Where necessary, the software will automatically dial a phone modem station.
If you choose Yes to begin the walkthrough, the software takes you through the
following dialog boxes:
• Station Configuration
Set station name, model, accessories, download options, and data file exten-
sion.
• Choose Units
Select units of measure in which station information is displayed.
• Serial Port Settings
Set COM port to which data logger is connected. The COM port is created by
the software included with your USB/serial port adapter. Specify modem con-
nection settings such as baud rate, phone number, and modem initialization
string.

Set the time and date on the station, software, and computer and make sure all
three are synchronized.
Note: When you set the time and date, you will be prompted to clear your 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 sta-
tion) so you may safely clear the archive memory.
•SetArchiveInterval
Set the interval at which data will be stored in the data logger’s memory. This
will clear any data stored in the data logger.
• Set Station Alarms

Troubleshooting Guide
The following section answers some of the most commonly asked questions about
WeatherLink.®Please consult this guide and the on-line help files before contact-
ing Technical Support (see page 16).
Communications Problems
? Why can’t the software communicate with the data logger and station?
If you are having trouble establishing communication between the weather
station and WeatherLink, start by checking the weather station’s own diagnos-
tics. Remove all power to the weather station and then restart it by restoring
power (with the data logger still attached).
Note: Vantage Pro Only - The data logger uses non-volatile memory, so you won’t
lose any data you’ve already recorded. However, make sure to put the con-
sole in Setup Mode by pressing and holding the [DONE] key, then pressing
the [-] key before removing the batteries. This ensures the station will not try
to write any data as the power goes off.
• You should hear three beeps, 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 tells you the processor is running.
The second beep will be for the logger (if installed) and the third beep is
for the display. If you do not hear one or more of these beeps, contact
Technical Support (see page 16). (You’ll only hear two beeps if you don’t
have the data logger installed.)
• If you hear all three beeps, See “Checking the Serial Port” on page 14 for
instructions on checking your serial port. Also check your USB/serial port
adapter to make sure it is correctly installed and operating properly.
• Make sure you are using the DIN cable connector supplied with
WeatherLink for Mac OS X. Other adapters may not work.
• Check the Baud Rate setting on the console (Vantage Pro Stations) or the
data logger (Original Stations) and in the serial port dialog box in the
software. Make sure they’re set to the same rate.
▲Vantage Pro Only-Enter the console’s Setup Mode by pressing and
holding the [DONE] key, then pressing the [-] key on the console. Scroll
through the setup choices by pressing the [BAR] or [DONE] keys until
you reach the Baud Rate screen. This screen only appears if the data
logger is plugged into the console.
▲Original Stations Only-Check the switch setting on the data logger. It
will be set to either 1200 or 2400 Baud.
If you still cannot connect or if the loopback test verifies the serial port, check
the following list of potential problems. If you have questions on how to pro-
ceed, contact the vendor or technical support for your computer.
• Your serial port uses a non-standard device name.
• Your serial port adapter is defective.
• The loopback connector or the WeatherLink adapter plug is bad.

TROUBLESHOOTING GUIDE
Communications Problems

Checking the Serial Port
The software includes a procedure for testing the serial port to which your station
is connected. Using the Loopback command (as opposed to Test) will help you
determine whether the serial port or the data logger is causing a communication
problem. The loopback function will also detect and report the presence of any
modems.
To use this procedure, you will need the loopback connec-
tor (the short cable with a phone jack on one end and a red
plastic tip on the other) supplied with Weatherlink.
1. If necessary, disconnect the cable between your sta-
tion and the adapter connected to the COM port.
2. Insert the loopback connector into the adapter.
3. Choose Serial Port from the Setup menu.
The software opens the Serial Port dialog box
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.
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 may not be working. Consult your computer documentation
for help.

Program Problems
? The barometer graph on the Bulletin does not “fill in” completely.
When you first load the bulletin, the barometer graph will only fill in com-
pletely 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.
? I have duplicate records in my database. Why?
If you do not download from the data logger 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 dupli-
cated 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 to change the record in one day
does not change the record in the other day.
Note: Do not delete the duplicate midnight records; it may affect your rain data-
base or NOAA monthly summary.
? No wind direction reading (or dashes instead of a reading) appears in my data-
base.
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.
? WeatherLink says “No new data to download” but I know there’s data there.
What can I do?
Vantage is smart enough to send only data it hasn’t already sent to the com-
puter. 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 cal-
ibration numbers and alarm settings will remain intact. If this doesn’t work,
reboot your weather station (that is, remove, then restore all power to the sta-
tion).
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 not try to write any data when the power goes off.

? After successfully downloading, recent or new data does not appear to be in my
database. Where is it?
Check to see if the time and date on your station are incorrect. (This can hap-
pen if you have a power outage and your battery backup is dead.) If so, the
data was written into the wrong month, day, and/or time. Reset the time and
date.
It is also possible, if you have multiple stations, that you downloaded data
into the wrong station’s database. Make sure you’ve opened the correct station
before downloading.
Your data logger may be not be operating properly. If this is the case, you can
restore proper operation by repowering the data logger:
1. Remove power from the data logger by removing power from the
weather station console.
2. Remove or disconnect the data logger from the console.
3. Wait at least one minute.
4. Connect the data logger to the weather station console.
5. Apply power to the console.
6. If you can now download and see the data in WeatherLink you have
fixed the problem. If not, please contact Technical Support for assis-
tance.
? 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 sen-
sor (for example, the sensor was malfunctioning), the software dashes out the
entry rather than showing invalid data. You can use the record editor to cor-
rect these entries.
