ANEMOMETER TRANSMITTER KIT 

INSTALLATION MANUAL

This manual describes how to install the Anemometer Transmitter Kit for a Wireless
Vantage Pro2

TM

Weather Station. The kit enables you to connect the anemometer from
your Integrated Sensor Suite (ISS) to its own transmitter, so it can be located away from
the ISS and communicate directly with your 
console/receiver.

Components

The Anemometer Transmitter Kit includes the following components and mounting
hardware:

1/4" Flat Washers

1/4" Lock Washers

1/4" Hex Nuts

3-Volt

Lithium

Battery

U-Bolts

1/4" x 1-1/2" Lag Screws

8" Cable Ties

Transmitter Shelter

#6 x 1/2" (3.5 x 12 mm)

Self-Threading Screw

#6 Washer

Cable Clamp

Tools for Setup

In addition to the kit, you will need some or all of the following materials:

• Adjustable wrench or 7/16" wrench

• Compass or local area map

• Ballpoint pen or paper clip (small pointed object of some kind)

• Drill and 3/16" (5 mm) drill bit (if mounting on a vertical surface)

• Carpenter’s level (if mounting on a vertical surface)

If You Are Installing the ISS and the Anemometer Transmitter Kit
at the Same Time

Install your ISS first, following the instructions in the ISS manual. However, during the
step “Preparing the ISS for Installation,” DO NOT connect the anemometer cable to the
SIM. When you have mounted the rain collector side of the ISS and are ready to mount
the anemometer, follow the instructions in this manual starting with “Preparing the
Anemometer Transmitter” on page 3.

Installation Steps

The following is an outline of the steps necessary to install the Anemometer Transmitter
Kit. These steps are used as section headings in this manual and are explained in greater
detail in the appropriate section.

• Remove the anemometer from its current location (if necessary)

• Disconnect the anemometer from the ISS transmitter

• Unfasten and remove the anemometer

• Prepare the anemometer transmitter

• Insert the battery

• Plug the anemometer cable into the transmitter

• Set the transmitter ID on the anemometer transmitter using DIP switches

• Set the console to recognize the signals

• View current wind data

• Putting your anemometer transmitter into TEST mode

• Choose a location for the anemometer transmitter

• Test transmission from the proposed mounting location

• Mount the anemometer and transmitter shelter in the new location

• A note on securing cables

• Troubleshooting

• Contacting Davis Technical Support

Removing the Anemometer from its Current Location

The following two steps assume that your ISS is already mounted. If it is in a high
location such as a rooftop, please read through the instructions before climbing up, and
watch your balance while installing your Anemometer Transmitter Kit.

Disconnecting Anemometer from ISS Transmitter

Open the SIM Box and unplug the anemometer cable from the receptacle labeled WIND
on the SIM. Guide the anemometer cable through and free from the grommet. Or in the
case of the Vantage Pro2 SIM Box, guide the anemometer cable free of the cable access
port by first removing the foam insert and then guiding the cable out of the box. When
finished, make sure to replace the foam insert ensuring that the Access Port is filled and
free of any voids.

If Your ISS is Mounted as a Single Unit (Both Sides Together on
a Pole)

Unfasten the anemometer:

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 collector cone
first.

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

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 go

es 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.

If Your Anemometer is Mounted by Itself

Unfasten it: use an adjustable wrench or 7/16" wrench to remove the hex nuts or lag
screws.

Preparing the Anemometer Transmitter

The illustration below shows the Sensor Interface Module, or “SIM”, inside the
transmitter shelter.

1. Insert the 3-volt

lithium b

attery into
the battery holder,
matching the “+” sign
on the battery with the
“+” sign on the SIM.

2. Push the end of the
anemometer 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 also remove
the grommet, thread
the cable through it
and then replace the
grommet in the shelter
if that is easier for
you.

3. Plug the end of the anemometer cable into the receptacle labeled WIND on the SIM.

4. Place the cable clamp over the anemometer cable between the grommet and the
re

ceptacle. Secure the cable clamp to the shelter by threading the provided #6 screw
through the washer, then cable clamp and then screwing it into the cable clamp mount
inside the housing. (See the above illustration.)

5. Locate the DIP switches. You will work with them during the next installation step.

Setting the Transmitter ID

Each wireless transmitting station must be set to one of eight transmitter IDs. DIP
switches #1, 2 and 3 on the SIM allow you to control the ID — the “channel” the station
will transmit on. (DIP switch #4 is used for transmission testing, not for transmitter ID.)

Note: The transmitter and your console communicate with each other only when both are set to the

same ID.

The factory default transmitter ID is ‘1’. Looking at the table below, you can see that
means all three DIP switches are in the OFF position when each transmitting station
leaves the factory, whether it is an ISS, an anemometer transmitter, or another kind of
station.

The ISS is included with every Wireless Vantage Pro,

and the console/receiver is factory

set to find the ISS on ‘1’. Since it is likely that your ISS is already set to ID ‘1’, you

will need to set the ID of your anemometer transmitter to a different ID number.
Use a ballpoint pen or paper clip to toggle DIP switches #1, 2, and 3. The settings for

transmitter IDs 1 – 8 are shown in the table below:

ID CODE SWITCH 1 SWITCH 2 SWITCH 3

#1 (default) off off off

#2 off off ON
#3 off ON off

#4 off ON ON
#5 ON off off
#6 ON off ON

#7 ON ON off
#8 ON ON ON

Use this table to ensure that each wireless transmitting station in your system is
broadcasting on its own transmitter ID.
