Wireless Leaf & Soil Moisture/Temperature Station
Installation Manual
For Wireless Vantage Pro2
™
and Vantage Pro2 Plus
™
The Wireless Leaf & Soil Moisture/Temperature Station (referred to in this document
as the Leaf/Soil Station) can be used with any Wireless Vantage Pro2 weather station
to measure leaf wetness, soil moisture, or temperature.
The following Vantag e Pro2 console station configurations can be used with the
Leaf/Soil Station:
Station Type in

Configuration
LEAF/SOIL Station 2 4 4
LEAF Station 2 - 2
SOIL Station - 4 4
Number of Leaf
Wetness Sensors
Number of Soil
Moisture Sensors
Number of
Temp Probes
• Only one Leaf/Soil Station can be installed as a Leaf/Soil Station per Vantage Pro2
Weather Station.
• Two stations can be installed if one is configured as a Leaf Station and the other
station is configured as a Soil Station in the Vantage Pro2 console.
• Configured as a Leaf Station, the Station supports two leaf wetness sensors and
two temperature probes.
• Configured as a Soil Station, it supports up to four soil moisture sensors and temperature probes.
Note: In any station using soil moisture sensors, the correspo nding temperatu re probe, if in stalled , will be
used for temperature compensation of the soil moisture sensor.
Tools for Setup
In addition to the components shown, you will need some or all of the following
materials:
• Adjustable wrench or 7/16" wrench
• Medium Phillips Screwdriver
• 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)

Preparing the Leaf/Soil Station
The following illustrations show the location of the transmitter ID DIP switches, the
battery mounting location, the modular connectors used by the leaf wetness sensors,
and the terminal blocks used to connect the soil moisture sensors and temperature
probes.

holder, matching the “+”
sign on the battery with
the “+” sign next to the
battery mounting
brackets.
2. Note the location of the
DIP switches. You will
work with them during
the next installation step.

Temporarily Connecting a Sensor for Testing
Temporarily connect at least one of the following sensors.
Note: You must have at least one sensor installed in the Leaf/Soil station in order to test wireless com-
munications.
Leaf Wetness Sensor Connection
• Connect the leaf wetness sensor cable to the LEAF
1 or LEAF 2 receptacle by plugging it in the proper
receptacle.
Soil Moisture Sensor Connection
T emporarily connect a soil moisture probe to the SOIL
1 terminal block connector using the following instructions.
1. Use a pen or small screwdriver to open the
connector “jaws” as shown in the illustration at the
top of the next page.
2. While the jaws are open, insert the temperature probe leads, then let the connec-

tor jaws close in on the lead by removing the pen or small screwdriver.
Note: The soil moisture sensor must be moist to be used for this test. A completely dry sensor will not
register on the console.

Soil Temperature Sensor Connection
Temporarily connect a temperature probe to the
TEMP 1 terminal block connector.
1. Use a pen or smal l screwdriver to open the
connector “jaws” as shown in the illustration to
the right.
2. While the jaws are open, insert the temperature
probe leads, then let the connector jaws close in
on the lead by removing the pen or small screwdriver.

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 Sensor Interface Module (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: A transmitter and receiver 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 the DIP switches are in the OFF position when each transmitting station
leaves the factory . This is true for all Davis wireless equipment.
1. Verify the transmitter ID used by your ISS, as well as all other transmitter IDs
already used by your Vantage Pro2 Weather Station.
2. Configure the Leaf/Soil Station to a transmitter ID not already in use.
3. 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
(default) OFF OFF OFF
#1
#2 OFF OFF ON
#3 OFF ON OFF
#4 OFF ON ON

Setting Console/Receiver(s) to Same ID
1. Put your console into Setup Mode — press and hold DONE and press the down
arrow (-).
• The console displays the words: “RECEIVING FROM...” and “STATION
NO.” followed by the transmitter IDs that your console detects. One of these
should be the ID number you just set on the Leaf/Soil Station transmitter. It
can take up to two minutes to show all transmitter IDs received.
• If you don’t see the station on the console screen, make sure the console is
within 10' of the transmitter, and verify that you set the DIP switches correctly. Wait a few seconds and if you still don’t see it, go to “Troubleshooting
Communication Problems” on the next page.
2. Press DONE to move to “Screen 2: Selecting Transmitters.”
• Setup Mode – Screen 2 is where you will set the console to recognize signals
on that ID as coming from a Leaf/Soil Station.
3. Press the left (<) or right (>) arrows to scroll through transmitter IDs.
• When you see the ID you chose for the Leaf/Soil Station, press the up (+) or
down (-) arrows to activate reception of that ID code. Make sure the screen
shows “ON (ISS)”.
4. Press GRAPH several times to change the station type in the console from ON
(ISS) to ON (LEAF), ON (SOIL), or ON (LEAF/SOIL).
• Configure it as a LEAF Station if you are only using it for leaf wetness and
temperature.
• Configure it as a SOIL station if you are only using it for soil moisture and
temperature.
• Configure it as a LEAF/SOIL station if you are using it for both leaf wetness
and soil moisture.
5. To exit Setup Mode, press and hold DONE.
Note: See the Vantage Pro2 User’s Manual & Setup Guide: “Setup Mode – Screen 2: Selecting Trans-
6
mitters” for more information.
