2. Remove the battery cover by pressing on the arrow embossed on the cover
and sliding the cover away from the case.
3. Insert three AA-cell batteries, negative terminal (flat side) first. The Envoy
emits two beeps if the start-up test is successful. If you do not hear two
beeps, check your battery orientation and reinstall the batteries. If you hear
no beeps again, please contact Davis Instruments Technical Support. See
“Contacting Davis Technical Support” on page 19.
4. Replace the battery cover on the case.
Optional: Connecting AC Power
The operating battery power for a cabled Weather Envoy is approximately 10
days. For a wireless Weather Envoy, the battery power is approximately 5
months.
The Weather Envoy is supplied with an optional AC power adapter that can be
used as an optional power source.
Note: If installing the optional AC power supply, make sure the WeatherLink Data Logger is
already installed and that the backup batteries are installed.

Optional: Adding an External Temperature Probe (Wireless Envoy Only)

1. Locate the power adapter jack on the end of the Envoy case. It’s next to the
data logger output cable.
2. Insert the power adapter plug into the power jack.
Optional: Connecting a Cabled Envoy to the Sensor Suite
Refer to the figure shown above “Connecting AC Power”.
1. Insert the modular plug into the sensor suite jack on the Envoy case.
Note: You won’t be able to test the connection between the Envoy and the sensor suite
until you have finished installing the WeatherLink software.
Optional: Adding an External Temperature Probe
(Wireless Envoy Only)
Your wireless Weather Envoy has a built-in temperature-humidity sensor as
well as the barometer. The temperature and humidity are reported as “Inside
Temperature” and “Inside Humidity.”
In some instances, such as when your Envoy is mounted outside in a shelter,
the temperature inside the shelter is of little interest. You may replace the
built-in temperature-humidity sensor with an external temperature probe, with
a 25’ (7.6 m) cable, which can be used to measure the temperature of air,
water, or soil. The External Temperature Probe with RJ connector comes in
two models: 6475 (with stainless steel housing) or 6477 (with durable plastic
housing).

Mount Your Weather Envoy
You can place your Envoy on your desktop, install it on a wall near your
computer, or install it with the optional Universal Shelter (#6618). Here are
some guidelines for placing your Weather Envoy.
Envoy Location
You should place the Envoy in a location where it is easily accessible and can
be easily connected to a computer. For more accurate readings, follow these
suggestions:
• Avoid placing the Envoy in direct sunlight. This may cause erroneous
inside temperature and humidity readings and may damage the unit.
• Avoid placing the Envoy near radiators or heating/air conditioning ducts.
• If you are mounting the Envoy on a wall, choose an interior wall. Avoid
exterior walls that tend to heat up or cool down depending on the weather.
The range of the radio transmission that the Envoy can receive from the
wireless sensor suite depends on several factors. Try to position the Envoy as
close to the transmitting weather station as possible for best results.
Typical maximum ranges are:
• Line of sight: 1000 feet (300 m).
• Under most conditions: 200 - 400 feet (60 - 120 m).
Other range and transmission considerations include:
• Range may be reduced by walls, ceilings, trees, foliage, a metal roof or
other large metal structures or objects such as aluminum siding, metal
ducts, and metal appliances, such as refrigerators.
• Transmission between wireless units may be obscured by something
unidentifiable, or by some obstacle that can’t be worked around.
Note: For best results, orient the sensor suite antenna and the Envoy antenna so that the
orientation and angles of the antennas are parallel to each other.
For better reception over greater distances or for weaker signals, consider
using a Wireless Repeater (#7626 or 7627) or Long-Range Repeaters (# 7654)
to strengthen the signal or increase the distance between your sensor suite and
the Envoy.
Wall Mounting the Envoy
1. Use the provided wall mounting template on the next page as an example of
hole spacing and alignment when installing your Envoy.
2. Use the template as a guideline for the hole markings on the wall where you
want to mount the Envoy, and use a pencil to mark the location for the two
mounting screws.

Mount Your Weather Envoy

The screws should be 3.25'' (82.5 mm)
apart and lined up vertically.
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'' (3.5 mm x 25 mm)
pan head self-threading screws into the
wall.
5. Leave at least a 1/8'' (3 mm) space
between the wall and the heads of the
screws.
6. Slide the keyholes on the back of the
case over the two screw heads.

Local Computer Installation
The following instructions contain the basic procedures for connecting and
setting up a local or remote connection between your Weather Envoy and a
computer. Additional setup not described in this manual is required for all
Weather Envoy, Vantage Pro and Vantage Pro2 consoles. See the WeatherLink
Getting Started Guide for complete instructions on connecting the data logger
to your computer. Also, see WeatherLink Online Help for additional setup
instructions.
USB Connection
Locate a free USB port on your computer and connect the USB connector of
the 8’ cable to the port., and connect the Mini-B connector to the data logger.
The connection between the Envoy and the computer can be extended up to
16' (5 m) using a Mini-B-to-USB connector cable.
Note: Do not attempt to use more than a 16' extension cable, or the data logger may have
difficulty communicating with the computer.
Serial Port Connection
These instructions explain how to make a typical local connection between
your Envoy and your computer via a serial port. Note that if you extend the
cable run beyond 48' (14.4 m), the software may have difficulty
communicating with the station.
1. Locate a free serial port on the back of your computer and connect the blue
DB9 adapter to the port, then connect the 8’ cable to the adapter.
2. Plug the short cable coming from the data logger into the 8' cable.
The connection between the Envoy and the computer can be extended up to
40’ (12m) using a Davis Standard 4-conductor extension cable (#7876-
040).

Local Computer Installation

Note: Do not attempt to use more than 40' of extension cable, or the data logger may have
difficulty communicating with the computer. Warning: Do not use phone cable. Our
cable looks like a phone cable but it is wired differently
Note: The data logger does not require a constant connection with a computer to continue
logging and storing data. Although the data logger should remain connected to the
Envoy at all times, the data logger only needs to be connected to the computer when
data is being downloaded or when the computer is actively using data from the data
logger. The data logger and Envoy can be disconnected from the computer if the
Envoy is placed in a location where the data logger cable cannot reach. However,
WeatherLink’s bulletin, summary, or other real-time window displays are only
accessible if the Envoy is attached to the computer.

Troubleshooting Guide
The following section answers some of the most commonly asked questions
about WeatherLink®and the Weather Envoy. Please consult this guide and the
WeatherLink software Help before contacting Davis. Please see Contacting
Davis Technical Support on page 19 for more information.
Communications Problems
If you are having trouble establishing communication between
WeatherLink and the Weather Envoy, start by checking the Envoy’s own
diagnostics. Follow these steps:
Note: The data logger uses non-volatile memory, so you won’t lose any data you’ve already
recorded.
1. Remove power, both AC and batteries. Remove any extension cables
that are in the system.
2. Unplug the data logger.
3. Wait at least two minutes, then plug the data logger back in. Make sure it is
plugged in firmly and completely.
4. On power up, you should hear two beeps, each of which occurs when the
Envoy passes one of its diagnostic tests. Each beep follows the previous after
about a second. The first beep tells you the processor is running. The second
beep verifies the installation of the data logger. If you do not hear two beeps,
contact Davis Instruments Technical Support.
5. If you hear both beeps, see Troubleshooting Serial Port Communication on
page 15 for instructions on checking your standard serial ports. See
“Troubleshooting USB Communication” on page 17 if you are
troubleshooting a USB connection. See “Program Problems” on page 18 if
you are troubleshooting an TCP/IP connection.
Note: Generally, if the loopback test identifies a serial port, your PC is not the problem.
Troubleshooting Serial Port Communication
• Test the serial port using the loopback connector (the
short cable with a phone jack on one end and a red
plastic tip on the other) supplied with a serial port data
logger. 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
loopback connector is not found, there is a problem
with the port or the computer.
• Check the serial port adapter if using a serial port connection. Use only the
blue serial port adapter supplied with WeatherLink. Older models, or mod-
els not supplied in the WeatherLink connection kit, are not compatible.

• If the port settings or the loopback process identifies a serial port other
than the one selected, try again using that port.
1. If necessary, disconnect the cable from the blue serial adapter.
2. Insert the loopback connector into the adapter.
3. Select Communications Port from the Setup menu.
The Communications Port dialog box displays.
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 still does not exist or if the loopback
test identifies the same serial port you have
selected, eliminate the following possibilities:

Communications Problems
17
Note: Contact your PC vendor or technical support for more information on device difficulties.
•Hardware device conflict: Check the Device Manager tab in the Win-
dows 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: Weather-
Link recognizes serial ports named COM1 through COM18 only.
• Your serial port is defective.
• The loopback connector or the WeatherLink blue serial adapter plug is
defective.
Note: See the WeatherLink Online Help if you are troubleshooting a Modem connection.
Troubleshooting USB Communication
• Close the WeatherLink software.
• Disconnect the USB cable from the Envoy.
• Plug the cable back into the Envoy.
• Open the WeatherLink software again.
• Open the Communications Port dialog box. Select USB if USB is not
selected in the communications field and follow the prompts.
• Click Test to verify communication between the station and the software.
If the test is unsuccessful, either the station is malfunctioning or the drivers
for communicating with USB have not been installed successfully. To
verify that the driver is installed, look in Windows’ System Properties ->
Device Manager -> Universal Serial Bus Controllers and see if the
USBXpress Device is listed. If the driver is listed and there is still no
communication between the station and the computer, call Technical
Support. If the drivers are not listed, contact Technical Support for
instructions on installing the necessary drivers.
• If you are using a third party application that requires the USB connection
to emulate a com port connection, see WeatherLink Online Help for more
information or contact Technical Support.

Program Problems

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
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.
?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.
?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. Reboot and reseat the data logger. Follow the steps on
page 15, Communications Problems. Older data may still be in the data logger,
if you have not cleared its memory. To see how many of these older records
are stored in the logger, create a new station (File>New Station) and download
the data into this new database. Because there are no records stored in the
database 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 cali-
bration 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).
?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
