WELCOME TO THE W EATHER ENVOY!
Contents
Welcome to the Weather Envoy!
Welcome to Davis Instruments’ Weather Envoy! The Weather Envoy pr ov ides a
new and exc iting way of getting your Davis weathe r station data into your
Windows (95 or later) or Macintosh (OS X) computer.
The Weather Envoy includes the data collection and logging functions of the Vantage Pro console, but in a smaller package that can be discreetly placed next to
your computer. Both cabled and wireless versions of the Weather Envoy are available. In combination with our WeatherLink software, the Weather Envoy allows
you to view, store, plot, analyze, export, share and print your weather data.
Contents
Before continuing, please be sure your Weather Envoy package includes the
following:
▲ Envoy console
▲ Two #6 x 1” screws for wall mounting
▲ AC-power adapt er
Required for Operation
In order to use your Weather Envoy, you will also need the following Davis
weather products:
All Weather En voys:
▲ WeatherLink for Vantage Pro (Windows version 5.2 or later (#6510C), Mac OS
X version 5.01 or later (#6520C))
Wireless Weathe r Envoy :
▲ Wireless Int eg rated Sensor Suite (ISS) or ISS Plu s
or
▲ Wireless Vantage Pro (Plus) Weather Station
Cabled Weather Envo y:
▲ Cabled ISS or Cabled ISS Plus

Optional Accessories
Optional Accessories
The following optional accessories are designed for use with your Envoy. They
are available from your dealer or may be ordered directly from Davis.
▲ Telephone Modem Adapter (#6533)
Allows transmission of data from the data logger using a modem.
▲ Standard 4-Conductor 40’ Extension Cable (#7876-040)
For more flexibility in the placement of your Weather Envoy, add one 40’
(12 m) extension cable to extend the distance between your station and the
computer. (48’ (14.4 m) maximum)
Hardware Installation
The Weather Envoy allows two types of installation: local connection to a
computer and remote connection to a computer via a modem. Requirements and
installation for each type of connect ion differ, and are explained separa te ly below.
Hardware Requirements
Note: The amount of storage space necessary for the data files depends on the archive
interval. Each archive record in the database is 88 bytes. Every day in the database
has an additional two records totalling 176 bytes that store daily summary information. A database containing data stored at a 30-minute archive interval requires
approximately 4400 bytes of disk space per day or 132KB of disk space per month.
The disk space requirements change in a linear fashion depending on the archive
interval. For example, data stored at a one-minute interval requires approximately 3.8
MB a month while data stored at a two-hour interval requires approximately 32 KB a
month.
Local Connection Windows Computer Re quirements
Your Weather Envoy requires the following for a local Windows computer
connection:
▲ Computer running Windows™ 95, 98, 2000, XP, ME, or NT 4.0 with at least 5
MB of free disk space
▲ Windows-compatible display
VGA minimum. SVGA or High (16-bit) Color or better recommended.
▲ One free serial port
Local Connection Macintosh Computer Re quirements
Your Weather Envoy requires the following for a local Macintosh computer
connection:
▲ Macintosh computer running Mac OS X v10.01 or newer with at least 5 MB of
free disk space
▲ A USB to serial port converter connected to a Mac in tosh USB port.

4. Rejoin the case halves, making sure the data logger cable passes through the
cable channel.
5. Fasten using the three screws you previously removed.
Installing the Batteries
CAUTION: The WeatherLink Data Logger must be instal led before you install the
backup batteries!
1. Find th e batte ry cover on the back side of the Envoy case.
2. Remove the battery cover by pressing on the arrow embossed on the cover
and sliding the cover away from the case.

Preparing the Envoy
3. Insert the three AA-c ell batteries, negati ve terminal (f lat side) fi rst.
The Envoy will run through a brief self-test procedure. If the test is successful
you will hear two (2) beeps.
4. Replace the battery cover on the case.
Note: Operating on battery power alone, the Cabled Weather Envoy will run approximately
10 days and the Wireless Weather Envoy will run approximately 5 months.
Connecting AC Power
CAUTION: The WeatherLink Data Logger and the backup batteries must be
installed before you connect AC power!
1. Locate the power adapter jack on the end of the Envoy case. It’s next to the
data logger ou tput cable.

Preparing the Envoy
Mounting the Envoy
You can insta ll your Envo y on your desktop or on the wall next to you r compute r.
Note: Whenever you first install the Weather Envoy , place the antenna in a vertical position.
If necessary, you can adjust the angle for best reception after it’s installed.
Use this procedure for a wall installation.
1. Find the template located on the ne xt page.
2. Hold the template against the wall where you want to mount the Envoy, and
use a pencil to mark the location for the two mounting screws.
The screws should be 3.25” (82 .5mm) apart and lined up vert ically.
3. Drill the marked locations with a 3/32” or 7/64” ( 2.2 to 2.7 mm) drill bit.
4. Drive the two #6 x 1” (~ 3.5mm x 25mm) pan head self-threading screws into
the wall.
Leave at least a 1/8” (~ 3mm) space between the wall and the heads of the
screws.
5. Slide the keyholes on the back of the case over the two screw heads.

Local Computer Installation
The instructions below explain how to make a typical local connection. Note that
if you extend the cable run beyond 48’ (14.4 m), the software may have difficulty
communicating with the station.

Local Computer Installation
Installing with a Lo cal Com puter
1. Locate a free serial port on the back of your computer and connect the DB9 to
the port.
2. Insert the cable plug at the end of the shor t cable coming fr om the data log ger
into the receptacle on the end of the 8’ cable. Then insert the cable plug on the
end of the 8’ cable into the DB9 adapter.
The cable connecting the data logger to the computer is 8’ (2.4 m) long. If you
need to place the station cons ole more than 8’ from the computer, use a 40’ (12
m) standard 4-conductor extension cable (#7876 -040). Do not att empt to use
more than 40’ of extension cable, or the data logger may ha ve difficulty communicating with the computer .
Note: The Weather Envoy data logger does not need to be connected to the computer for
the logging to work. You can connect the cable to the computer when you’re ready to
download, then disconnect it if you want to place the Weather Envoy somewhere
else. However, the WeatherLink bulletin, summary, or real-time strip charts can be
displayed only while the Weather Envoy is attached to the computer.
