ANUAL
With this interface, some anemometers not manufactured by Davis Instruments
can be used with the Vantage Pro2. Non‐Davis anemometers must have AC
voltage output signals. The frequency of the AC signal must be linearly propor‐
tional to the wind speed.
This interface has been tested with R. M. Young anemometers, model number
05103; and with NRG anemometers, model 1900 NRG#40C or MAX40. How‐
ever, the interface is not limited to those products.

- Tools for Setup
- Installation Steps
- Remove the old anemometer from its current location
- 1. Remove the black rain collector cone from its base by rotating cone counter-clockwise until its latches line up with openings in the base and you can lift it off. It is much easier to reach the hex nuts with a wrench if you remove the rain collect...
- 2. Using an adjustable wrench or 7/16" wrench, remove the hex nuts and washers holding the anemometer’s plastic mounting base on the pole. Set the anemometer down for a moment.
- 3. Remove the hex nuts and washers holding the rain collector side on the pole. Retrieve the U-bolt that was holding the anemometer.
- 4. Using the washers and hex nuts, fasten the rain collector side back onto the pole. Flat washer goes on first, then lock washer, then hex nut.
- 5. Put the rain collector cone back on. Rotate the cone clockwise until the latches slide into place.
- Mount the New Anemometer
- Mount the Interface Shelter
- Mounting on a pole
- 1. While holding the shelter against the pole, place a U-bolt around the pole and through the two holes on at the top of the shelter.
- 2. Place a flat washer, a lock washer and a hex nut on each of the bolt ends.
- 3. Using an adjustable wrench or 7/16" wrench, tighten the nuts.
- 4. Place the second U-bolt around the pole and through the two holes at the bottom of the shelter. Put a flat washer, a lock washer, and a hex nut on each bolt end, and tighten the hex nuts.
- Note: Remember to position the shelter so the solar panel has maximum exposure to the sun.
- Mounting on a vertical surface
- 1. With a 3/16" (5 mm) drill bit, drill two holes approximately 2" (50 mm) apart. Use a carpenter’s level to ensure the holes are level.
- 2. Drill two more holes 7-1/32" (17.9 cm) below the upper holes.
- 3. Insert the 1/4" x 1-1/2" lag screws through the flat washers, and through the holes at the top of the shelter into the post. Using an adjustable wrench or 7/16" wrench, tighten the lag screws.
- 4. Insert the 1/4" x 1-1/2" lag screws through the flat washers, and through the holes at the bottom of the shelter into the post. Using an adjustable wrench or 7/16" wrench, tighten the lag screws.
- Note: Remember to position the shelter so the solar panel has maximum exposure to the sun.
- Insert the Battery
- Connect the Cable to the New Anemometer
- 1. Open the junction box on the anemometer and cut the jumper wire. (Its location is marked “JUMP FOR COMMON REF”.)
- 2. Unscrew the sealing nut on the strain relief.
- 3. One end of the 6-connector cable has five colored wires, tinned and stripped, and a white (unused) wire. Feed this end of the cable through the sealing nut and the strain relief into the junction box.
- 4. Connect the wires to the numbered terminal strip as follows:
- 5. Replace the junction box cover and sealing nut.
- 1. Use only the black and blue wires. Connect the black wire to the anemometer’s black ground wire and the blue wire to the anemometer’s white signal wire.
- 2. Connect the red and green wires together.
- Connect the Anemometer Cable to the Interface
- 1. Open the interface shelter. Feed the loose end of the 6-conductor anemometer cable up through the square black grommet at the base of the shelter. (The Davis shelter has two of these grommets to provide weather-resistant entrances for cables. In t...
- 2. Plug the end of the cable into the RJ jack labeled “IN.”
- 3. Locate the anemometer selector jumper and move the shunt to the correct pins, as illustrated
- Connect the ISS Cable to the Interface
- 1. Feed one end of the 4-conductor ISS cable into the same grommet as the 6- conductor cable.
- 2. Plug it into the RJ jack labeled “OUT.”
- 3. Secure both cables inside with the cable clamp. Place the cable clamp over both cables between the grommet and the receptacle. Secure the cable clamp to the shelter by threading the provided #6 screw through the washer and cable clamp and then scr...
- 4. Close the shelter, being careful not to pinch the solar panel cable.
- Connect the ISS cable to the SIM
- 1. Open the Vantage Pro2 transmitter shelter.
- 2. Pull the foam insert out of the cable access port in between the cables and set the foam aside.
- 3. Insert the ISS cable through the cable access port with the connector lever down.
- 4. Firmly insert the end of the ISS cable into the connector labeled WIND. The lever clicks into place.
- 5. Make sure that the cables lie flat on the bottom of the cable access port.
- 6. Firmly insert the foam in between the cables and 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.
- Note: Refer to your Vantage Pro2 ISS Installation Manual for more information.
- 1. This illustration shows the Sensor Interface Module, or “SIM”, inside the Vantage Pro2 transmitter shelter.
- 1. Push the end of the ISS cable up through the square black grommet into the transmitter shelter. Every Davis shelter has two of these grommets to provide weather-resistant entrances for cables. In this case, use the grommet on the right. You can al...
- 2. Place the cable clamp over the ISS cable between the grommet and the receptacle. Secure the cable clamp to the shelter by threading the provided #6 screw through the washer and cable clamp and then screwing it into the cable clamp mount inside the...
- Note: Refer to your Anemometer Transmitter Kit Manual for more information.
- Configure the Console
- Note: If your are not using an R.M. Young anemometer, you must use a Vantage Vue console. This console allows for the special calibration needed.
- Note: Early firmware versions may not have the OTHER option. You can update your firmware at www.davisnet.com/support.
- 3. Press and hold DONE to return to the current weather screen.
- 1. Enter Setup by pressing and releasing 2ND and then SETUP.
- 2. Press and release DONE until Screen 6: Transmitter IDs appears.
- 3. Press and release DONE to scroll to Screen 12: Wind Cup Type.
- 4. Press the “+” and “-” keys to scroll through the three wind cup options and select “OTHER.”
- Note: If you are using an R.M. Young anemometer skip to Step 6.
- 5. If your anemometer required that P2 pins 2 & 3 be shunted (e.g. not an R.M. Young), you must calibrate the Vantage Vue console. Follow these additional steps to determine the calibration number and calibrate the console: a. Review your anemometer...
- Example: The NRG40C/Max 40 anemometer has a transfer function of V = (F x 0.756) + 0.35. Therefore the calibration number is 1000 x 0.756, or 0756. c. On the console, press 2ND and GRAPH to display “WIND CAL NUMBER”.
- d. Press the “<“, “>”, “+” and “-” keys to select the number derived above.
- If You Do Not See Current Wind Readings
- Note: It is assumed that the ISS or Anemometer Transmitter Kit has been installed and tested as instructed in the ISS or Anemometer Transmitter Kit manual.
- 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.
- Troubleshooting
- The signal from the wind cups is not being received by the console. Check your cables for visible nicks and cuts. Look for corrosion in the WIND jack on the Sensor Interface Module and on splices in the cable (if any). If none of these steps solve th...
- Be very careful. Comparing to measurements from TV, radio, newspapers, or a neighbor is NOT a valid method of verifying your readings. If you have questions, contact your anemometer manufacturer.
- Contacting Davis Instruments
- Note: Try to identify the source of a problem before contacting Technical Support. If the problem is with the anemometer, you should contact that manufacturer’s technical support. If the problem is with the Universal Anemometer Interface or the Van...
