- Page 5 The wireless Vantage Pro2 sensor suite collects outside weather data and sends the data to a WeatherLink Console. The sensor suite can also transmit data to WeatherLink Live, a Vantage Pro2 or Vantage Vue console, or other Davis wireless receiver. The wireless sensor suite is solar-powered and sends data via radio.
- Page 6 Included Components and Hardware The sensor suite comes with all the components and hardware shown in the following illustrations. If you purchased your sensor suite as part of a weather station package containing the WeatherLink Console or a cabled console, additional components may be included in the package that are not shown here.

These steps apply to all versions of the sensor suite, unless otherwise noted. Tip: Use a well-lit work table or work area to prepare the sensor suite for installation. Assemble the Anemometer The anemometer measures wind direction and speed.
- Page 10 4. Slide the tooth-lock washer and hex nut onto the machine screw. Tighten the hex nut while holding the screw with a Phillips-head screwdriver to prevent it from turning. 5. Press the sensor cable firmly and completely into the zig-zagging channel in the base, starting from the arm and progressing downward to the bottom of the base.
- Page 11 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.
- Page 12 Optional: Disconnect the solar panel connection wire 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.
- Page 13 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 cable end into the Sensor cable access port from Interface beneath the box.

- Page 16 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.
- Page 17 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.
- Page 18 Note: If another Davis weather station is within range of your console or other Davis receiver, you should change the Transmitter ID. Remember to use the same ID on the sensor suite and on the Console.
- Page 19 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.) DIP Switches Transmitter ID DIP switches in top-right corner of sensor interface To change to another ID, use a ballpoint pen or paper clip to toggle DIP switches #1, 2, and 3.
- Page 20 Setup the WeatherLink Console Note: If you are using a WeatherLink Live or other Davis receiver, please refer to your receiver manual to set it up. 1. Power the console if it does not already have power. 2. Follow the prompts on the WeatherLink Console to configure it to “listen” to your sensor suite.
- Page 21 Optional: Verify Data On a WeatherLink Live (no console): 1. 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.
- Page 22 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, anemometer cable length, and wireless transmission range when siting the station.
- Page 23 • 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).
- Page 24 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). •...
- Page 25 Connected should say “Yes.” 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 sensor suite or try moving the console and sensor suite to different positions. WeatherLink Live: 1.

- Page 33 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 Solar Radiation Sensor Top should be even with or...
- Page 34 Solar Radiation and UV Sensors: 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 35 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.
- Page 36 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. CAUTION: 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.
- Page 37 Maintaining a 24-Hour Fan-Aspirated Radiation Shield The 24-hour fan draws in outside air. To clean it, disassemble the shield and clean interior surfaces as necessary to prevent dirt build up. Check to make sure the fan is running by carefully listening for it. The motor is very quiet.
- Page 38 Remove the rain collector cone. Using a Phillips-head screwdriver, remove the three screws connecting the rain collector base to the threaded spacers. While removing the screws, support the radiation shield from the bottom. When the screws are removed, the two bottom plates may drop. Take note of the cable placement and routing so you can replace it correctly.

- Page 42 15. Replace the two cap plates. (Note that the closed plate goes on top.) Replace the solar bracket and the threaded spacers, with lock washers and flat washers. Threaded Spacer Lock Washer Flat Washer USE THESE HOLES 16. Align the threaded spacers with the screws in the rain collector base. Note that cables should exit from the radiation shield toward the mounting pole or post.
- Page 43 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.
- Page 44 5. Unscrew the three threaded spacers. Threaded Spacer 6. Remove the three screws from the Fan Plate bottom of the radiation shielding and separate the shield stack, taking care to maintain the order in which the plates are assembled. 7. Remove all debris from inside the shield and wipe the interior surfaces.
- Page 45 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.
- Page 46 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.
