Mount Your Weather Envoy
You can place your Envoy on your desktop, install it on a wall near your com-
puter, or install it with the optional Multi-Purpose Shelter (7728). 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 (or router if using WeatherLinkIP). 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 wire-
less ISS 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.
• Frequency interferers also reduce transmission distance. Cordless phones
(900 Mhz) are a common example of frequency interference.
• 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 ISS antenna and the Envoy antenna so that the orienta-
tion 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 (#7653
or 7654) to strengthen the signal or increase the distance between your ISS 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
9
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.
IP Connection
1. Locate the Weather Envoy with the WeatherLinkIP data logger attached.
2. Remove power, both AC and battery.
3. Connect one end of the Ethernet cable to the WeatherLinkIP data logger.

Local Computer Installation
11
4. Locate a free Ethernet port on your broadband or DSL router and connect
the cable to the port.
5. Reconnect the AC adapter.
Note: An Envoy using a WeatherLinkIP data logger requires use of the AC-power adapter.
Battery power can be used for short-term backup power in the event of a power outage,
but an Envoy with WeatherLinkIP should use the AC-power adapter as its main source of
power.
The Weather Envoy beeps two times, occurring within one second of each
other. On power-up, the IP data logger will negotiate its connection with
the router.
6. Write down the Device ID and Key located on the side of the
WeatherLinkIP data logger for further use.
The Device ID (DID) and Key uniquely identify your data logger on the
WeatherLink Network (www.weatherlink.com). They are both required to
create a login on WeatherLink.com and are used to connect the
WeatherLinkIP data logger to the software.
Note: Because WeatherLinkIP is continuously uploading current weather information to the
www.weatherlink.com, leave the WeatherLinkIP and Envoy connected to your router at all
times.

Local Computer Installation

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 communicat-
ing 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).
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 acces-
sible 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 20 for more information.
Communications Problems
If you are having trouble establishing communication between Weather-
Link and the Weather Envoy, start by checking the Enovy’s own diagnos-
tics. 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 “Trou-
bleshooting USB Communication” on page 17 if you are troubleshooting a
USB connection. See “Troubleshooting WeatherLinkIP Communication” 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. Use the loopback connector
• 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

Note: Contact your PC vendor or technical support for more information on device difficulties.
•Hardware device conflict—Check the Device Manager tab in the
Windows System Properties dialog box to ensure that Windows recog-
nizes 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— Weath-
erLink 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.

Troubleshooting WeatherLinkIP Communication
Note: An Envoy using a WeatherLinkIP data logger requires use of the AC-power adapter.
Battery power can be used for short-term backup power in the event of a power outage,
but an Envoy with WeatherLinkIP should use the AC-power adapter as its main source of
power.
1. See if you have a connection to the internet established. Verify that you can
access a website from a computer connected to the router or switch that the
WeatherLinkIP data logger is using.
2. Check the cable connection between your WeatherLinkIP data logger and
the broadband router. Check if the green light on the WeatherLink IP data
logger is on or blinking.
3. Leaving the data logger connected to your router, disconnect power from
both your router and your Envoy, both AC and batteries.
4. Return power to the router. Wait for at least one minute as the router reboots
and re-establishes connections.
5. Return AC power to the Envoy. On power up, you will hear two beeps.
6. Check if the green light on the WeatherLink IP data logger is on. If it is not
on, contact Technical Support.
7. For Weatherlink.com - Wait five minutes. Go to www.weatherlink.com
and register the WeatherLinkIP data logger using the Device ID and Key.
