The Integrated Sensor Suite collects outside weather data and sends the data to a
Vantage Pro2 console. The wireless sensor suite can also transmit data to
WeatherLink Live, a Vantage Vue console, or other Davis wireless receiver. The
wireless sensor suite is solar-powered and sends data via radio. The cabled sensor
suite sends data via cable to one cabled Vantage Pro2 console, cabled Weather
Envoy, or cabled Vantage Connect and receives power via the console.
Tip:One wireless sensor suite can transmit to any number of receivers within its range,
so you can add additional receivers or consoles to use in different rooms.
All Vantage Pro2 sensor suites include a rain collector, temperature sensor, humidity
sensor, and anemometer. Temperature and humidity sensors are mounted in a passive
or fan-aspirated radiation shield to minimize the impact of solar radiation on sensor
readings. The anemometer measures wind speed and direction and can be installed
adjacent to the sensor suite or apart from it. See “Locating the Sensor Suite and
Anemometer” on page 19 for siting guidelines.
The transmitter shelter contains the “brain” of the sensor suite: the sensor interface
and the transmitter. It collects outside weather data from the sensor suite sensors and
then transmits the data to your Vantage Pro2 console, Vantage Vue console (wireless
only), WeatherLink Live (wireless only), Weather Envoy, or Vantage Connect.
Other versions of the sensor suite have additional features:
•Wireless Vantage Pro2 with Fan (product number 6153): Includes a 24-Hour
Fan-Aspirated Radiation Shield.
•Wireless and cabled Vantage Pro2 Plus (product numbers 6162 & 6162C):
Includes a pre-installed Solar Radiation Sensor and a UV Sensor.
•Wireless Vantage Pro2 Plus with Fan (product number 6163): Includes UV
and Solar Radiation Sensors, and a 24-Hour Fan-Aspirated Radiation Shield.
•Wireless and Cabled GroWeather (product numbers 6820 & 6820C) include a
a Solar Radiation Sensor.
•Wireless and Cabled GroWeather with 24-Hour Fan-Aspirated Radiation Shield (product number 6825 & 6825C) and Solar Radiation Sensor.
Mounting Shelf (prod. no. 6673), and Daytime Fan-Aspirated Radiation Shield (prod.
no. 7747) are available to upgrade a standard sensor suite.

Check Sensor Interface Connections and Connect the
Anemometer Cable
The sensor interface is located in the transmitter shelter on the front of the sensor
suite station. It contains the connections for all the sensors of the sensor suite.
Follow the steps below to check the sensor interface and ensure that all sensors are
connected properly.
Open the Transmitter Shelter
1. Locate the white box with the solar panel containing the sensor interface on the
front of the sensor suite unit. (The cabled model does not have a solar panel.)
2. Locate the white tab at the bottom center of the shelter cover.
3. Pull the tab away from the box while sliding the cover up.
4. Look on the side of the shelter. The box cover can be easily removed from the box
when the alignment indicator on the cover is lined up with the alignment indicator
on the box
5. Pull the cover off the box, being careful not to stress the solar panel cable when
removing the cover.
6. The sensor interface is visible once the cover has been removed.

points of interest on the sensor interface.
7
Page 12
Optional:
Disconnect the solar panel connection wire (wireless versions) and the fan cable (fan
versions).
The solar panel on the box cover is connected to the sensor interface by a wire. If
your sensor suite has a fan, the fan cable will also connect the cover to the sensor
interface. If the cover cannot be set aside while still connected to the sensor interface
safely, those cables can be disconnected.

Page 13
Check the Factory-Installed Sensor Connections
1. Verify that the rain collector and temperature/humidity sensor cables are plugged
into the receptacles labeled RAIN and TEMP/HUM on the sensor interface.
2. If your sensor suite includes UV and/or solar radiation sensors, verify that the
sensor cables are plugged into the receptacles labeled UV and SUN on the sensor
interface.
Connect the Anemometer Cable to the Sensor Interface
Note: The anemometer comes with 40 feet (12 meters) of cable to allow for mounting the
anemometer separately from the rain collector and other sensors. The cable is coiled
and secured at the factory with enough cable unwound from the coil to allow you to
work with it and to allow the anemometer to be mounted on the same pole as the rain
collector.
1. Remove the protective cap from the RJ jack on the anemometer cable.
2. Pull the foam insert
out of cable access
port and set the foam
insert aside.
3. Insert the anemometer

and at the top of the
cable access port,
taking care to ensure
that the foam seals the
access port entirely, leaving no holes or gaps large enough for weather or insects.
You may have to stack the cables to allow the foam to fit.
Note: If you are assembling a cabled station, wait to reinsert the foam until cable assembly is
complete. See “Cabled Sensor Suite Assembly” on page 11.

Apply Power and Verify Communication with the
Console
The 100' (30 m) console cable provides power to the sensor suite and is used to send
data from the sensor suite to the console. The console cable can be extended up to
1000' (305 m) in length with extension cables purchased from Davis Instruments.
With the console powered, plugging the cable into the console powers the sensor
suite and establishes communication between the sensor suite and the console.
1. Locate the 100' console cable included with your system.
2. Pull the foam insert out of cable access port, if it has been reinserted. Insert the
console connector cable end into the cable access port from beneath the sensor
interface box. Slide the cable through the cable access port with the connector tab
down.
3. On the sensor interface, firmly insert either end of the 4-conductor cable into the
modular receptacle labeled COMM.

4. If you haven’t powered up the console yet, refer to the installation instructions in
the Vantage Pro2 Console User Manual and apply power to the console.
5. On the bottom of your console, insert the other end of the console cable into the
modular receptacle labeled “ISS.”
6. Firmly insert the foam in between the cables and at the top of the cable access
port, taking care to ensure that the foam seals the access port entirely, leaving no
holes or gaps for weather or insects. See the graphic on page 9 for more
information on inserting the foam insert.
7. If the console is in Setup Mode, press and hold DONE until the Current Weather
screen displays. A flashing "X" in the lower left hand corner indicates that the
console is receiving data. Sensor readings from the sensor suite should display on
the screen.

Verify Data from the Sensor Suite Sensors
1. Near the center of the screen, look for the outside temperature (TEMP OUT).
2. Spin the wind cups to check wind speed, pressing WIND if necessary to alternate
between speed and direction in the compass rose.
3. Turn the wind vane and allow five seconds for the wind direction display to
stabilize before moving it again.
4. Approximately one minute after power-up the outside relative humidity (HUM
OUT) reading should be displayed on the console.
5. Check to see if your console is receiving rain readings. On your console screen,
look for the DAILY RAIN display. Remove the rain collector cone and tip the
spoon, then wait to see if the display registers a rain reading. Each tip indicates
0.01" or 0.2 mm of rain and may take up to a minute to register at the console. If
the spoon is tipped too quickly, the number on the console display may not
change.
6. If the sensor suite contains a UV sensor and/or solar sensor, press 2ND and then
press RAIN YR for current ultraviolet readings or press 2ND then press RAIN
DAY for solar radiation readings.
The UV reading displays in the center of the console. The solar reading displays
in the bottom right corner of the console display. UV and solar readings should be
zero or close to zero if the sensor suite is inside. Zero is a valid reading. Dashes(-
-) are displayed if no data comes from the sensors.
7. Current weather data displayed on the console confirms communication.
Once the sensor suite has been powered and the console has successfully received
accurate readings from all the sensors, prepare the sensor suite for installation.
Continue on to “Plan the Sensor Suite Installation” on page 19.
If there is a communication problem between the wireless sensor suite and the
console, see below: “Troubleshooting Cabled Sensor Suite Communication” on
page 13.
To make installation easier at a location, disconnect the console cable from the
sensor interface. Remove the foam and slide the cable out through access port. Once
a location for both the sensor suite and the console has been arranged, reinsert the
cable through the access port, into the console connector, and reinsert the foam.

Troubleshooting Cabled Sensor Suite Communication
If the console is not receiving sensor readings from the sensor suite, try the
following troubleshooting procedures.
•Check the console to make sure it is being powered with the AC adapter supplied
in the Vantage Pro2 package or three C batteries.
Note: The batteries are intended for backup power, or for testing during set up, but they will
drain quickly if used to power a cabled console. You should always use the AC adapter
to power your system for normal use. The supplied adapter is a 5-volt positive center
AC to DC adapter. Other adapters may not work if the voltage or adapter type is
different.
•Make sure the cable is firmly plugged into the sensor suite ("ISS") jack on the
console.
•Make sure that the cable is firmly plugged into the jack labeled COMM on the
sensor interface.
•Verify that all sensor cables are firmly plugged in.
•A green LED indicator light on the sensor interface flashes each time the sensor
suite transmits a packet, which is about once every 2.5 seconds. If the LED
remains dark, there is no power to the sensor suite. Call Technical Support. See
“Contacting Technical Support” on page 42.
See “Sensor Interface” on page 45 for information on locating the LED indicator
light.
If the console is still not receiving readings, ensure that the console is in Setup Mode
and reboot the console by disconnecting the AC power adapter from the console and
removing the console batteries for at least 30 seconds. If the console is still not
displaying sensor readings from the sensor suite after powering back up, please
contact Davis Technical Support.

Wireless Sensor Suite Assembly
The sensor suite has a wireless connection to a Vantage Pro2 wireless console or
other receiver. Once the anemometer has been installed and the sensor connections
have been checked, the sensor suite must be powered and a wireless communication
channel must be established between the sensor suite and the receiver.
Apply Power to the Wireless Sensor Suite
Energy from the solar panel is stored for power at night. A factory-installed lithium
battery is an alternative power source the sensor interface uses when it is depleted. In
the sensor transmitter, remove the battery pull tab. Make sure the battery is firmly
seated. Once powered, the sensor suite immediately begins transmitting data.
Check Transmitter ID
A Vantage Pro2 console can receive data from
up to 8 different wireless transmitters. The
default Transmitter ID for the sensor suite and
ON
1234
console is 1.
In most cases it will not be necessary to change
the Transmitter ID. The console and sensor suite should begin communicating
automatically when power is applied.
Note: If another Davis weather station is within range of your console or Vantage Connect,
you should change the Transmitter ID. Remember to use the same ID for the sensor
suite and console. See “Optional: Changing the Sensor Suite Transmitter ID” on
page 17.
Settings for Transmitter ID 1:
DIP Switch 1 = OFF
DIP Switch 2 = OFF
DIP Switch 3 = OFF
Verify Communication with a Console
1. Power the console if it does not already have power. Refer to the Vantage Pro2
Console User Manual and apply power to the console.
The console automatically enters Setup Mode when powered up.
2. If the console is not in Setup Mode, press and hold DONE then press the down
arrow. The message RECEIVING FROM... and STATION NO. followed by the
Transmitter IDs that the console detects displays on the console screen.
3. Look for the sensor suite Transmitter ID. The number 1 displays unless the
Transmitter ID has been changed. If the sensor suite Transmitter ID is displayed,
the sensor suite is detected.
Note: If the console does not display the number of the sensor suite Transmitter ID setting,
see “Troubleshooting Wireless Sensor Suite Reception” on page 16 for more
information. It can take several minutes for the console to acquire and display all the
available Transmitter IDs.
4. Press and hold DONE to view sensor suite data once the sensor suite Transmitter
ID displays.
14
Page 20
Verify Data from the Sensor Suite Sensors
On a console:
1. If the console is in Setup Mode, press and hold DONE until the Current Weather
screen displays. A flashing “X” in the lower right hand corner indicates that the
console is receiving data packets. This may take a few minutes.
Sensor readings from the sensor suite should display on the screen.
2. Near the center of the screen, look for the outside temperature (TEMP OUT).
3. Spin the wind cups to check wind speed, pressing WIND if necessary to alternate
between speed and direction in the compass rose.
4. Turn the wind vane, and allow 5 seconds for the wind direction display to
stabilize before moving it again.
5. Approximately one minute after receiving data, the outside relative humidity
(HUM OUT) reading should be displayed on the console.
6. If the sensor suite contains a UV sensor and/or solar radiation sensor, press 2ND
and then press RAIN YR for current ultraviolet readings or press 2ND then press
RAIN DAY for solar radiation readings.
7. The UV reading displays in the center of the console. The solar reading displays
in the bottom right corner of the console display. UV and solar readings should be
zero or close to zero if the sensor suite is inside. Zero is a valid reading — dashes
are displayed if no data comes from the sensors.
8. Current weather data displayed on the console confirms successful
communication.
On a WeatherLink Live (no console):
If you are using your Vantage Pro2 sensor suite with a WeatherLink Live without a
console, you will need to set up your WeatherLink Live and your account on
WeatherLink.com in order to see incoming data. However, during setup and
installation, erroneous data may be received by the WeatherLink Live and this data
will become part of your archive. For example, if you verify data while your sensor
suite is inside your home or workshop, an erroneous “outside” temperature will be
recorded; if you tip the rain tipping spoon while mounting the sensor suite,
erroneous rain will be recorded.
To avoid erroneous data, you may want to place your sensor suite outside before
powering up your WeatherLink Live. Wait to see outside temperature data on
WeatherLink.com, which may take up to 10 minutes.
Be sure to power down the WeatherLink Live until after final installation.
Once the sensor suite has been powered and the console and/or WeatherLink Live
has successfully received accurate readings from all the sensors, prepare the sensor
suite for installation. Continue on to “Plan the Sensor Suite Installation” on page 19
for more information.
If there is a communication problem between the wireless sensor suite and the
console, see See “Troubleshooting Wireless Sensor Suite Reception” on page 16.

Troubleshooting Wireless Sensor Suite Reception
If the console isn’t displaying data from the sensor suite, perform the following
steps:
1. Verify that the console is powered and is not in Setup Mode.
2. Make sure that all sensor suite sensor cables are firmly connected to the sensor
interface and the sensor suite battery is properly installed.
3. Walk around the room with the console, standing for a few moments in various
locations, to see if you are picking up signals from the sensor suite. Look on the
screen’s lower right corner. An “X” toggles on and off when the console receives
a transmission packet. If an “R” appears, the console is trying to find the signal. If
an “L” appears, the console is in “sleep” mode and will not try to find the signal
until it “wakes up.” See your Vantage Pro2 Console User Manual for more
information.
4. If you do not see the “X” slowly blinking, no matter where you stand with the
console, put your sensor suite in Test Mode.
• The DIP switch #4 on the sensor
interface is the Test Mode switch. Switch
ON
it to the ON position, using a ball-point
pen or paper clip.
1234
• In test mode, a green LED indicator
light on the sensor interface flashes each
time the sensor suite transmits, which is
about once every 2.5 seconds.
See “Sensor Interface” on page 45 for information on locating the components
and points of interest on the sensor interface.
5. If the LED remains dark, there is a problem with the sensor suite transmitter. Call
Technical Support. See “Contacting Technical Support” on page 42.
6. If the LED flashes repeatedly but your console isn’t picking up a signal anywhere
in the room, it could be related to one of the following causes:
• You changed the sensor suite Transmitter ID at the sensor suite or console, but
not at both.
• Reception is being disrupted by frequency interference from outside sources.
Interference has to be strong to prevent the console from receiving a signal
while in the same room as the sensor suite. In high-interference environments,
it may be preferable to install the Cabled Vantage Pro2
• There is a problem with the console.
7. If a problem with receiving the wireless transmission still exists, please contact
Technical Support. See “Contacting Technical Support” on page 42.
8. When you are finished testing wireless transmission, set DIP switch # 4 to OFF to
take the sensor interface out of Test Mode.
Note: If the sensor interface is left in Test Mode, the blinking LED will significantly reduce
sensor suite battery life.
Setting for Test Mode
DIP Switch #4 = ON

Page 22
Optional: Changing the Sensor Suite Transmitter ID
Each wireless transmitting station, including the sensor suite, uses one of eight
selectable Transmitter IDs. DIP switches #1, 2 and 3 on the transmitter control the
ID — or channel — the station transmits on. DIP switch #4 is used for transmission
testing, not for the Transmitter ID.
Note: The transmitter on the sensor suite and the receiver on the console, WeatherLink Live
or other receiver communicate with each other only when both are set to the same ID.
The default Transmitter ID is 1 for both the sensor suite and the Vantage Pro2
console, and should work fine for most situations. Change the Transmitter ID if any
of the following issues are true:
•Another Davis Instruments wireless weather station operating nearby already
uses Transmitter ID 1.
•You have purchased additional Vantage Pro2 or Vantage Vue wireless
transmitting stations and one of the stations has already been designated as
Station No. 1.
On the sensor suite, the Transmitter ID is set using the DIP switches located on
the sensor interface. To access the sensor interface, open the transmitter shelter
cover. (See page 7.)

Plan the Sensor Suite Installation
Locating the Sensor Suite and Anemometer
For the weather station to perform at its best, use these guidelines to select the
optimum mounting locations for the sensor suite and anemometer. Be sure to
take into consideration ease of access for maintenance, sensor cable lengths
and wireless transmission range when siting the station.
Note: When selecting a location for installing your sensor suite, especially on a rooftop,
make sure it is a location far from power lines. Seek professional help if you are
uncertain about the safety of your installation.
General Sensor Suite Siting Guidelines
• Place the sensor suite away from sources of heat such as chimneys, heaters,
air conditioners and exhaust vents.
• Place the sensor suite at least 100' (30 m) away from any asphalt or concrete
roadway that readily absorbs and radiates heat in the sun. Avoid
installations near fences or sides of buildings that receive a lot of sun during
the day.
• Ideally, place the radiation shield of the sensor suite 5' (1.5 m) above the
ground in the middle of gently sloping or flat, regularly mowed grassy or
naturally landscaped area that drains well when it rains. For areas with
average maximum yearly snow depths over 3' (0.9 m), mount the sensor
suite 2' (0.6 m) above this depth.
• Never install the sensor suite where it will be directly sprayed by a sprinkler
system.
• Do not mount the sensor suite under tree canopies or near the side of
buildings that create “rain shadows.” For heavily forested areas, site the
sensor suite in a clearing or meadow.
• Site the sensor suite in a location with good sun exposure throughout the
day if the sensor suite is wireless or includes solar radiation or UV radiation
sensors.
For agricultural applications (important for evapotranspiration (ET)
calculations):
• Install the sensor suite and anemometer as a single unit with the radiation
shield 5' (1.5 m) above the ground and in the middle of the farm between
similar crop types (i.e. two orchards, two vineyards or two row crops), if
possible.
• Avoid areas exposed to extensive or frequent applications of agricultural
chemicals which can degrade the sensors.
• Avoid installing over bare soil. The ET formula works best when the
sensor suite is installed over well-irrigated, regularly mowed grass.
• If the last three guidelines cannot be met, install the weather station at the
edge of the primary crop of interest.
19
Page 25
Anemometer Siting Guidelines
• For best results, place the anemometer at least 7' (2.1 m) above surrounding
obstructions such as trees or buildings that obstruct wind flow.
• If mounting on a roof, mount the anemometer at least 7' (2.1 m) above the roof
apex. (When using a Davis Mounting Tripod, install the anemometer at the very
top of the pole).
• If mounting the sensor suite and the anemometer together, such as on a pole or a
wooden post, mount the anemometer so it is at least 12'' (0.3 m) above the top of
the rain collector cone for best results.
• The standard for meteorological and aviation applications is to place the
anemometer 33' (10 m) above the ground. Seek professional help for this type of
installation.
• The standard for agricultural applications is to place the anemometer 6' (2 m)
above the ground. This is important for evapotranspiration (ET) calculations.
Note: For roof mounting, and ease of installation, we recommend using the optional mounting
tripod (#7716). For other installations, use the Mounting Pole Kit (#7717).
Note: For more detailed siting suggestions, see Application Note #30: Reporting Quality
Observations to NOAA in the support section of www.davisinstruments.com

• All Vantage Pro2 stations include a 40' (12 m) cable to go between the sensor
suite and the anemometer. This can be extended up to 540' (165 m) using optional
extension cables purchased from Davis Instruments.

If most of the anemometer cable length is unused, the coiled cable length can be
stowed once the anemometer and sensor suite have been installed on a site. You
can secure the cable to the pole using the shorter cable ties. Use the longer cable
tie to secure the coil by running it through the holes on the rain collector shelf.
Keep the anemometer cable coiled if possible during the sensor suite and
anemometer assembly so that it is easily stowed once installation is complete.
• The Cabled Vantage Pro2 includes a 100' (30 m) cable to go between the console
and the sensor suite. This can be extended up to 1000' (300 m) using optional
cables.

Page 27
Optional: Wireless Transmission Considerations
The range of the radio transmission depends on several factors. Try to position the
transmitter and the receiver as close as possible for best results.
Typical maximum ranges include:
• Line of sight: 1000' (300 m).
• Under most conditions: 200 - 400' (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, televisions, heaters, or air conditioners.
• Transmission between wireless units may be obscured by something
unidentifiable, or by some obstacle that can’t be worked around.
• For best results, orient the sensor suite antenna and the console antenna so that the
orientation and angles of the antennas are parallel to each other.
If your ISS is directly overhead,
the orientation illustrated
here might work best.
(
(
(
(
(
(
For best reception, orient antennas
so they are parallel to each other.
CAUTION: The sensor suite and console antennas do not rotate in a complete circle. Avoid
forcing the antennas when rotating them.
• Consider using a Wireless Repeater (#7627) or Long-Range Wireless Repeater
(#7654) to strengthen the signal or to increase the distance between the sensor
suite and the console.
• You can use an additional Vantage Pro2 console (#6312) or Vantage Vue console
(#6351) set to retransmit to increase transmission distance.
22
Page 28
Testing Wireless Transmission at Sensor Suite Location
After a suitable place has been found for the wireless sensor suite, it is very
important to test reception from the installation location before permanently
mounting it there.
1. Set the sensor suite in the desired installation location.
2. Set the powered-up console and/or WeatherLink Live in the desired location.
Console:
1. Monitor your screen for data. You should see a flashing "X" in the lower right
corner and data should start to appear. This make take a few minutes.
2. If data does not appear, press and hold TEMP and press HUM to display
statistical and reception diagnostics on the console. See your Vantage Pro2 Console User Manual for more information on the diagnostic screens.
• It’s a good idea to test the console’s reception anywhere that you might want to
use or mount it now or in the future. Take your time. If you aren’t picking up a
strong signal where you intend to place your console, try rotating the antenna on
the console and sensor suite or try moving the console and sensor suite to
different positions.
• Irregular terrain in the area may interfere with the signal. For example, if the
sensor suite is mounted downhill from the console, the ground may block a
large percentage of the transmitted signal.
• Press and hold DONE to return to the Current Weather Mode when finished
testing.
Note: See the Troubleshooting section of the Vantage Pro2 Console User Manual for
information on how to check wireless signal strength and for more information on
troubleshooting reception problems.
WeatherLink Live:
1. Open your WeatherLink.com page.
2. Watch for outside temperature to appear on your page on WeatherLink.com
3. If data does not appear, click the Tools icon. (It looks like a wrench.) Choose
Health Data. Make sure the DavisTalk RSSI signal strength is above -90.
Note: See the Troubleshooting section of the WeatherLink Live User Manual for information
on how to check wireless signal strength and for more information on troubleshooting
reception problems.

Page 29
Install the Sensor Suite
Tip:To avoid erroneous data during installation when using a WeatherLink Live, be sure the WeatherLink
Live is powered down before installing the sensor suite.
The anemometer and the main part of the sensor suite can be installed either
together as a single unit on a pole, or apart from each other. The main part of
the sensor suite includes the rain collector, the temperature and humidity
sensors, the radiation shield, and the sensor transmitter. Use the U-bolts to
install the sensor suite and anemometer together or separately on a pole. Use
the lag screws to install them separately on a flat, vertical surface.
• The anemometer comes with a 40' (12 m) cable for flexibility in positioning
the system to monitor wind conditions. For example, the anemometer could
be mounted at the highest point of a roof, and the sensor suite could be
mounted on a fence closer to ground level.
• If you would like to install your anemometer even farther away from the
sensor suite or without using a cable, use a Davis Solar-Powered Sensor
Transmitter, #6332.
General Sensor Suite Installation Guidelines
• Install the sensor suite as level as possible to ensure accurate rain
measurements. Use the built-in bubble level (under the rain collector cone,
near the tipping spoon mechanism) or carpenter’s level to make sure the
sensor suite is level.
• In the Northern Hemisphere, the solar panel should face south for maximum
sun exposure, and the anemometer arm should point north for proper wind
direction calibration.
• In the Southern Hemisphere, the solar panel should face north for maximum
sun exposure. Either install the sensor suite and anemometer separately,
each facing north, or mount them as a single unit with solar panel facing
north and the wind vane re-oriented to the South. You will then need to
calibrate your console. ( See “Orient the Wind Vane” on page 25.)
Optional: Guidelines for Securing Cables
• To prevent fraying or cutting of cables, secure
them so they will not whip about in the wind.
• Secure cable to a metal pole using cable ties or
by wrapping tape around both the cables and the
Cable Clip
pole.
• Place clips or ties every 3' – 5' (1 – 1.6 m).
• Mounting clips, cable ties or additional hardware not included with your
station can be easily obtained at a hardware or electronics store.
Note: Do not use metal staples or a staple gun to secure cables. Metal staples — especially
when installed with a staple gun — have a tendency to cut the cables.

Page 30
Orient the Wind Vane
The wind vane rotates 360° to display current and dominant wind directions on the
compass rose of the console display. To obtain accurate readings, the vane must be
correctlyoriented when mounting the anemometer. The wind vane is factorycalibrated to report the correct wind direction if the anemometer arm points true
north.
To ensure correct wind direction data, mount the anemometer so that the arm points
true north.
If your anemometer arm cannot be mounted aiming true north, you will need to
calibrate the wind direction on your console to display accurate wind directions. See
your Vantage Pro2 Console User Manual.

Installation Options
s
There are several ways to mount and install the sensor suite unit. The following
installations are recommended. Individual sensor suite locations and installations
may vary.
•Installing the sensor suite and anemometer on a post or flat surface
•Installing the sensor suite and anemometer on a pole, together or
separately
Note: All installations require that the rain collector cone be removed for assembly.
Important: Use the built-in bubble level to ensure the main part of the sensor suite
is level.
Tip:If most of the anemometer cable length is unused, the coiled cable length can be stowed once the
anemometer and sensor suite have been installed on a site. You can secure the cable to the pole using
the shorter cable ties. Use the longer cable tie to secure the coil by running it through the holes on the

Accessories for Pole Mounting
• Use the Mounting Tripod (#7716) for easy mounting, especially on a roof.
• Use the Mounting Pole Kit (#7717) to raise the installation height by up to 37.5"
(0.95 m).
General Guidelines for Installing on a Pole
• With the supplied U-bolts, the sensor suite and anemometer can be mounted on a
pole having an outside diameter ranging from 1
• Larger U-bolts (not supplied) can be used to mount to a pole with a maximum
outside diameter of 2
1
/2" (64mm).
1
/4" to 13/4" (32 – 44mm).
• To mount on a smaller pole, obtain a U-bolt that fits the sensor suite base
openings but that has a shorter threaded section. If mounting on a smaller pole
with the included U-bolts, the bolt interferes with the rain collector cone. The
pole must be sturdy enough to be stable. Any movement of the pole will affect
wind and rain data.
• Use the built-in bubble level to ensure sensor suite is level.
Guidelines for Installing the Sensor Suite on a Pole
• When mounting the rain collector base and anemometer together on opposite
sides of the pole, remember that whichever side is mounted first, the U-bolt from
the opposite side must also be placed around the pole before tightening the Ubolts. (If it is not, there is no way to slide it in later.)
• In each side’s mounting base, there is a groove to accommodate the other
mounting base’s U-bolt.
• Once the two sides of the sensor suite have been loosely mounted together on the
pole, swivel the unit to the correct direction and then tighten the hex nuts. The
desired height can also be achieved by sliding the sensor suite vertically before
tightening.
Option 1: Installing the Sensor Suite and Anemometer Together
Try to install the sensor suite so the anemometer arm is aiming true north.
Note: If your anemometer arm cannot be mounted aiming true north, you will need to
calibrate the wind direction on your console to display accurate wind directions. See
your Vantage Pro2 Console User Manual.
1. Place the U-bolt for the anemometer around the pole so that its round end fits in
the top groove on the rain collector mounting base. The groove is right above two
large holes.
2. While holding the mounting base of the rain collector against the pole, place the
two ends of the remaining U-bolt around the pole and through the two holes in the
base.
3. Slide the metal backing plate over the bolt ends as they stick out over the rain
collector base. Loosely secure the backing plate with a lock washer and hex nut
on each of the bolt ends as shown previously.
Note: Leave the hex nuts loose to swivel the sensor suite base on the pole.
28
Page 34
4. The two ends of the anemometer’s U-bolt should now be pointing away from the
mounted rain collector side. Slide the anemometer’s mounting base over the
protruding bolt ends. Place a flat washer, a lock washer and a hex nut on each of
the bolt ends as shown above. Do not tighten the nuts yet.
5. Raise the sensor suite unit to the desired height on the pole and swivel it so the
anemometer arm is pointing north.
6. Using an adjustable wrench or 7/16" wrench, tighten all four hex nuts until the
sensor suite is firmly fastened on the pole.
Option 2: Installing the Sensor Suite Only
1. While holding the mounting base against the pole, place the two ends of a U-bolt
around the pole and through the two holes in the base.
2. Slide the metal backing plate over the bolt ends as they stick out toward the rain
collector cone. Secure the backing plate with a washer, a lock washer, and a hex
nut on each of the bolt ends. Do not tighten the nuts yet.
3. For the wireless sensor suite, swivel the sensor suite base so the solar panel is
facing south (in the Northern Hemisphere), or north (in the Southern
Hemisphere). (Not needed for cabled systems.)
4. Tighten the hex nuts using an adjustable wrench or 7/16" wrench.
Option 3: Installing the Anemometer Only
1. While holding the mounting base against the pole, place a U-bolt around the pole
and through the two holes in the base.
2. Place a flat washer, a lock washer and a hex nut loosely on each of the bolt ends.
3. Swivel the anemometer until the arm is pointing north.
4. Tighten the hex nuts using an adjustable wrench or 7/16" wrench.
Note: If your anemometer arm cannot be mounted aiming true north, you will need to
calibrate the wind direction on your console to display accurate wind directions. See
your Vantage Pro2 Console User Manual.

Finish the Installation
Close the Transmitter Shelter
1. If the solar panel cable (or the optional fan cable) were disconnected during
sensor suite assembly, reconnect them.
2. Find the two raised alignment
indicator lines on both the shelter and
the cover. Match these alignment
indicators as you place the cover
against the box.
3. Slide the cover down until it snaps
securely in place.
Re-Attach the Rain Collector
1. Set the cone back on the base so its latches slide
downward into the latch openings on the base.
Using the finger grips for a secure hold, rotate
the cone clockwise until it locks into place.
2. Place the debris screen, pointed end up, into the
cone over the funnel hole. Align the locking
grooves with the locks inside the cone and turn
to lock the screen in place.
3. In some installations, bird droppings can clog
the rain collector. To use the bird spikes, insert
one spike into each socket around the rim of the
cone. The sockets are tapered: push firmly or tap
lightly with a hammer for a more secure fit.
If you choose not to install the spikes, we recommend that you keep the packet of spikes in
case birds become a problem in the future.
4. If bird nesting is a problem, you can place a
spike in the hole on the top of the debris screen.

For most users, this is less serious than problems caused by birds. To maintain UV and
solar accuracy, remove the spikes near the sensors and use the fewest spikes that will
deter the birds. For more details and other options, see Application Note 37: Using Bird Spikes with Solar and/or UV Sensors on https://www.davisinstruments.com.

Page 36
Level the Solar and UV Sensors
If you have an sensor suite that includes a solar radiation and/or UV sensor, use the
bubble level on the sensors as a guide to verify that the sensors are level.
Adjust the level by tightening or
loosening the three screws that hold
each sensor onto the shelf. Make
Solar Radiation Sensor
Top should be even with or
above rain cone rim
sure that the sensor diffusers are not
shaded by the rim of the rain cone.
For the UV sensor, make sure the
entire comb structure is above the
rim of the rain cone.
For the Solar Radiation sensor,
make sure the top of the sensor
body is even with or above the rim
of the rain cone.
Note: If you are installing the solar or UV sensors separately, see the Solar Radiation and UV
Sensor installation manual for more information.
Start the 24-Hour Fan
If your sensor suite has a 24-Hour Fan-Aspirated Radiation Shield, the batteries are
factory installed with plastic tabs between the batteries and the contacts. This
prevents batteries from draining during shipping.
The two clear plastic tabs
extend out from the largest disk
in the radiation shield. Pull
them out to start the fan.

Clear Data Collected During Testing and Installation
Now that the sensor suite is mounted outside, any data that was collected in the
Vantage Pro2 console during testing and mounting can be cleared.
1. On the console, press the WIND so that graph icon appears adjacent to the wind
data on the display. Confirm that wind speed is displayed on the compass rose.
2. Press and release 2ND, then press and hold CLEAR for at least six seconds and
until you see “CLEARING NOW” in the console ticker display.
Additional Mounting Options
Add-on Sensors: Use a Solar- or AC-Powered Sensor Transmitter (#6332 and
6331) to collect data from additional sensors and send it directly to your console,
WeatherLink Live or other receiver. Each Sensor Transmitter can support one each
of up to five sensors: Anemometer or Sonic Anemometer, Temperature Probe or
Temperature/Humidity, Rain Collector, UV, and Solar Radiation. This allows you to
install your anemometer remotely or add on a remote temperature station, for
example. See “Using Multiple Transmitting Stations” on page 18 for the specific
combinations of transmitters and sensors your console and/or WeatherLink Live can
receive.
Add a Wireless Leaf & Soil Moisture/Temperature Station (#6345):
See your garden or agricultural data on your console.
Extend Wireless Transmission Range: Optional solar-powered repeaters can
be used to extend the wireless transmission range. Choose a Standard Wireless
Repeater (#7627) or Long-Range Wireless Repeater (#7654).
Use Cables for Remote Mounting:
Note: Not all cables are compatible with your Vantage Pro2 system. To be sure they will work,
order Davis extension cables from your dealer or directly from Davis Instruments.
Cabled Console:A cabled sensor suite can be extended up to 1000' (300 m) away
from the console by using Davis Instruments extension cables (#7876).
Anemometer: The anemometer can be extended further than 40' from the sensor
suite by using Davis Instruments extension cables (#7876).
Be aware that the maximum measurable wind speed reading decreases as the total
length of cable from the anemometer to the sensor suite increases.
Note: If the cable length is greater than 540' (165m), the maximum measurable wind speed
may be less than 100 MPH (161 km/h).
Solar Radiation and UV Sensors: The solar radiation and UV sensors have
a 3' (0.9 m) cable. If you wish to install these sensors away from the sensor suite, you
can extend the length of the sensor cables up to 125' (38 m) with Davis Instruments
extension cables (#7876).

Page 38
Maintenance and Troubleshooting
General Maintenance
You should keep the surfaces of the sensor suite clean, since the radiation shield and
solar panels are less effective when dirty. Remove dust from the solar panel and
radiation shield with a damp cloth.
Several times a year, inspect the rain collector and radiation shield and remove any
debris (such as twigs, leaves, webs and nests) obstructing water flow through the
rain collector or air flow through the radiation shield.
At least once a year, or more often in very dusty installations, dismantle and
thoroughly clean the radiation shield as described in the following pages.
Tip:Before maintaining your sensor suite, avoid recording erroneous data by powering
down your console and/or WeatherLink Live.
Note: Do not spray the sensor suite with insecticides of any kind. Some insecticides can
damage the sensors and even damage the radiation shield.
Maintaining UV and Solar Radiation Sensors
The UV and solar radiation sensors have an outer shell or shield, which protects the
sensor body from thermal radiation and provides a path for convection cooling of the
body, minimizing heating of the sensor interior. It houses the precision-shaped
diffuser, exposed through the top of the shield.
Try not to touch the small white diffusers on top of the sensors. Oil from skin
reduces their sensitivity. If you are concerned that you have touched the diffusers at
any time, clean with a soft cloth.
Due to the sensitivity of ultraviolet and solar radiation sensors, it is common practice
for manufacturers to recommend re-calibration after a period of time. Users
demanding high accuracy typically recalibrate their sensors annually. At Davis
Instruments, we have seen less than 2% drift per year on the readings from these
sensors. Contact Technical Support about returning your sensor for calibration. See
“Contacting Technical Support” on page 42.
Maintaining the Anemometer
The free movement of the wind vane and cups can be inhibited by dust, debris,
insects, and spider webs. With an Allen wrench, remove the cups and vane. Remove
any dust or debris from the shafts and housing. Turn the shafts the cups and vane
rotate on.While the wind direction shaft should have more resistance than the wind
cup shaft, if either feels gritty or stiff, contact Davis Technical Support. Reattach the
cups and vane and tighten with the Allen wrench.
Note: Do not lubricate the shaft or bearings in any way. When replacing the cups, make sure
they are not rubbing against any part of the anemometer head.
33
Page 39
Maintaining the Radiation Shield
The outer plating of the radiation shield should be cleaned when there is excessive
dirt and build-up on the plating. Wipe the outer edge of each ring with a damp cloth.
Note: Spraying down or using water excessively to clean the radiation shield can damage the
sensitive sensors or alter the data and readings the sensor suite is transmitting.
Check the radiation shield for debris or insect nests several times a year and clean
when necessary. A buildup of material inside the shield reduces its effectiveness and
may cause inaccurate temperature and humidity readings.
At least once a year, thoroughly clean your radiation shield. Follow the instructions
below for the correct version of your sensor suite’s radiation shield.
Tip:You will not need to remove the rain collector base from the pole or post.
Maintaining a Standard (Passive) Radiation Shield
1. Remove the rain collector cone.
2. Open the transmitter shelter and
unplug and remove the temphumidity cable.
3. While supporting the radiation
shield from the bottom, use a
Phillips-head screwdriver, to loosen
the three 4'' (~100mm) screws
holding the radiation shield plates
together.
4. Taking care to maintain the order in
which the five plates are assembled,
separate the plates as shown and
Plates
remove all debris from inside the
shield.
5. Inspect and clean any dust or debris
from the temperature/humidity
sensor inside the shield.
6. Reassemble the plates in the same
order in which they were
disassembled, and fasten them
together using a Phillips-head
screwdriver to tighten the 4" screws.
7. Plug the sensor cable in, then replace
the foam insert snugly. Check other sensor cables to make sure they are plugged
in tightly. If you disconnected the door’s solar panel cable, plug it back in.
Note: For some modelsthe order in which the five radiation shield plates are assembled may
be slightly different than the order shown in the figure. For this reason, ensure that you
always reassemble the plates in the same order in which they were disassembled.

Daytime Fan-Aspirated Radiation Shield
The Daytime Fan-Aspirated Radiation Shield (#7747) can be added to a standard
Vantage Pro2 or Vantage Pro2 Plus. It has a fan that is powered by a solar panel. It
differs from the 24-Hour Fan in that it has no batteries. This causes it operate during
the daytime when solar radiation effects are of the greatest concern, and to stop at
night.
Tip:You will not need to remove the rain collector base from the pole or post.
To clean the Daytime Fan Aspirated Radiation Shield
1. Remove the rain collector
cone.
2. Open the transmitter
shelter and unplug the

Maintaining the Rain Collector Cone
To maintain accuracy, thoroughly clean the rain collector several times a year.
Note: Cleaning the rain collector and tipping spoon may cause false rain readings. Unplug
the rain sensor from the sensor interface before cleaning so that no inaccurate
readings are logged, or clear the weather data that was logged on the Vantage Pro2
console after cleaning is complete. See your Vantage Pro2 Console User Manual for
instructions on clearing weather data.
1. Separate the cone from the base by turning it counter-clockwise.
2. Remove and clean the debris screen.
3. Use a soft, damp cloth to remove any debris from the cone and tipping spoon.
4. Use pipe cleaners to clear the funnel hole in the cone and drain screens in the
base.
5. Re-attach the cone and replace the debris screen. (If you unplugged the rain
sensor from the sensor interface, be sure to plug it back in.)
Troubleshooting
Sensor Functions Intermittently
Carefully check all connections from the sensor to the sensor suite. See “Check the
Factory-Installed Sensor Connections” on page 9.
Loose connections account for a large portion of potential problems. Connections
should be firmly seated in receptacles and plugged in straight. To check for a faulty
connection, try jiggling the cable while looking at the display. If a reading displays
intermittently on the console as the cable is jiggled, the connection is faulty. Try
removing and then re-installing the cable to correct the faulty connection. If the
sensor still functions intermittently contact Technical Support. See “Contacting
Technical Support” on page 42.
Readings Are Not What You Expect
Comparing data from your sensor suite to measurements from the Internet, TV,
radio, newspapers, or a neighbor is NOT a valid method of verifying your readings.
Readings can vary considerably over short distances. How you site the sensor suite
and anemometer can also make a big difference. If you have questions, contact
Technical Support.
Rain Collector Problem
If the rain collector seems to be under-reporting rainfall, remove the rain collector
cone to clean the tipping spoon and clear out any debris. Make sure the cable tie
around the tipping spoon has been cut and removed.
Anemometer Problems
“The wind cups are spinning but my console displays 0 mph.”
The signal from the wind cups may not be making it back to the display. Check
your cables for visible nicks and cuts. Look for corrosion in the WIND connector
on the sensor interface and on splices in the cable. If using an extension cable,
41
Page 47
remove it and test using only the anemometer cable. Contact Technical Support
and ask for a wind test cable if the problem has not been resolved.
Note: If the anemometer is not sending data, the wind display indicates 0 speed and “--” for
direction.
“The wind direction is stuck on north, or displays dashes.”
It is likely that there is a short somewhere between the wind vane and the display.
Check the cables for visible nicks and cuts. Look for corrosion in the “WIND”
jack on the sensor interface and on splices in the cable (if any). If possible,
remove any extensions and try it with the anemometer cable only. If none of these
steps get the wind direction working, contact Technical Support and ask for a
wind test cable.
“The wind cups don’t spin or don’t spin as fast as they should.”
The anemometer may be located where wind is blocked by something, or there
may be friction interfering with the cups’ rotation. Remove the wind cups (loosen
the set screw) and clear out any insects or debris. Turn the shaft the cups rotate on.
If it feels gritty or stiff, contact Davis Technical Support.
Note: Do not lubricate the shaft or bearings in any way. When replacing the cups, make sure
they are not rubbing against any part of the anemometer head.
Contacting Technical Support
For questions about the sensor suite or Vantage Pro2 system, please contact Davis
Technical Support. We’ll be glad to help.
Note: Please do not return items to the factory for repair before calling to get a Return
Materials Authorization number.
