The Wireless Leaf & Soil Moisture/Temperature Station (referred to in this docu-

ment at the Leaf/Soil Station) can be used with any Wireless Vantage Pro

weather station to measure leaf wetness, soil moisture or temperature.

The following Vantage Pro console station configurations can be used with the

Leaf/Soil station:

• Only one Leaf/Soil Station can be installed as a Leaf/Soil Station per Van-

tage Pro 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 Pro console.

• Configured as a Leaf Station, the Station supports two leaf wetness sen-

sors and two temperature probes.

• Configured as a Soil Station, it supports up to three soil moisture sensors

and temperature probes.

• A Wireless Soil Moisture/Temperature Station (#6361) can be used in con-

junction with a Leaf/Soil Station if the Leaf/Soil Station is configured as a

LEAF station in the Vantage Pro console.

Note: In any station using soil moisture sensors, the corresponding temperature probe, if

installed, will be used for temperature compensation of the soil moisture sensor.

Note: The Leaf/Soil Station requires Vantage Pro console firmware Rev B or later. (Press

and hold the [DONE] key then press the [+] (up arrow) key to display the console

firmware level.) Contact Davis Technical Support for upgrade information.

Preparing the Leaf/Soil Station

The following illustrations show the location of the DavisTalk transmitter 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.

Installing the Battery

1. Insert the 3-volt

lithium battery into

the battery 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 communications.

Leaf Wetness Sensor Connection

• Connect the leaf wetness sensor cable to the

LEAF 1 or LEAF 2 receptacle.

Soil Moisture Sensor Connection

• Temporarily connect a soil moisture probe to

the SOIL 1 terminal block connector.

• Use a pen or small screwdriver to open the

connector “jaws” as shown in the illustration.

• While the jaws are open, insert the tempera-

ture probe leads, then let the connector jaws close in on the lead.

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.

• Use a pen or small screwdriver to open the

connector “jaws” as shown in the illustra-

tion.

• While the jaws are open, insert the tempera-

ture probe leads, then let the connector jaws

close in on the lead.

Setting the DavisTalk Transmitter ID

Each wireless transmitting station must be set to one of eight DavisTalk trans-

mitter 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 DavisTalk 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 of Davis’ wireless equipment.

1. Verify the DavisTalk channel used by your ISS, as well as all other DavisTalk

channels already in use by your Vantage Pro Weather Station.

2. Configure the Leaf/Soil Station to a DavisTalk channel not already in use.

3. Use a ballpoint pen or paper clip to toggle DIP switches #1, 2, and 3. The set-

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

ID CODE SWITCH 1SWITCH 2SWITCH 3

#1(default) OFF OFF OFF

#2 OFF OFF ON

#3 OFF ON OFF

#4 OFF ON ON

#5 ON OFF OFF

Setting Console/Receiver(s) to Same ID

1. Put your console into Setup Mode — press and hold the DONE key and

press the DOWN (-) arrow key.

• The console will show you 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.

• If you don’t see it, 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 Prob-

lems” on the next page.

2. Press the DONE key to move on 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 (>) arrow key, or the STATION key, to scroll

through transmitter IDs.

• When you see the ID you chose for the Leaf/Soil Station, use the UP (+)

or DOWN (-) arrow keys to activate reception of that ID code. Make sure

the screen shows “ON”.

4. Press the GRAPH key to configure the station type in the console. The Leaf/

Soil Station can be configured as a LEAF/SOIL station, as a LEAF station, or

as a SOIL station.

• Configure it as a LEAF Station if you are only using it for leaf wetness

and temp.

• Configure it as a SOIL station if you are only using it for soil moisture

and temp.

• Configure it as a LEAF/SOIL station if you are using it for both leaf wet-

ness and soil moisture.

5. To exit Setup Mode, press and hold the DONE key.

Note: See the Vantage Pro User’s Manual & Setup Guide: “Setup Mode – Screen 2:

Selecting Transmitters” for more information.

Testing Station Communications

1. If you are using a Soil Moisture sensor to test the station, press the TEMP

key until you see “SOIL MOIST” displayed on the console screen where the

inside temperature is usually displayed. If you are using a Leaf Wetness

sensor, press the HUM key until you see “LEAF WET” displayed where you

usually see the inside humidity. Both the TEMP and HUM keys will display

temperatures if you are using a temperature probe to test the station.

• Soil temperature is displayed in the TEMP OUT location on the LCD.

Leaf temperature is displayed below the barometer reading on the LCD.

• If you see SOIL MOIST or LEAF WET and no number, you are seeing the

moisture and temperature readings for sensor pair #1. A two or three

will appear above the readings for the second or third set of sensors.

2. If you continue to press the TEMP or HUM key, you will see the readings for

sensor pairs #2and #3 (#3 displayed for soil moisture and temperature only).

• If no sensor is installed, the reading for that sensor will be dashed out.

3. A soil moisture, temperature, or leaf wetness reading confirms communica-

tion between your Leaf/Soil Station and the console.

• Disconnect the sensor(s) that were temporarily installed to test commu-

nications.

• Go on to “Choosing a Location to Mount the Station” on page 8.

If your console does not show a sensor reading, proceed to “Trouble-

shooting Communication Problems

Troubleshooting Communication Problems

First, verify that the console/receiver is powered and is not in Setup Mode (exit

Setup Mode by pressing DONE key and holding it for a moment). Then, on the

Leaf/Soil Station, check that the battery is properly installed. Walk around the

room with the console, standing for a few moments in various locations to see

if you are picking up signals.

If you don’t see any readings, no matter where you stand with the console, put

the transmitter in TEST mode as described below.

TEST mode

DIP switch #4 on the SIM (see illustration on page 6) is the TEST DIP-switch.

Switch it to the ON position using a ball-point pen or paper clip. This puts the

transmitter in Test Mode. An LED indicator light will flash each time it

transmits:

• The LED will immediately flash once to show that the light itself func-

tions.

• Then it will flash each time the transmitter broadcasts a signal, which

should be every 10 seconds.

If the LED flashes only once and then remains dark, there is a problem with the

transmitter. See “Contacting Davis Technical Support” on page 19.

Page 8 Wireless Leaf & Soil Moisture/ Temperature Sta-

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:

• The DIP switches were not correctly set on the transmitter.

• Review the procedure on page 5.

• The ID was not correctly set on the console/receiver.

• Review the procedure on page 6.

• Reception is being disrupted by RF (radio frequency) interference.

• There is a problem with the console/receiver.

See “Contacting Davis Technical Support” on page 19.

Note: Remember to turn DIP switch #4 OFF when you’re finished testing wireless

transmission. If it is left ON, the blinking LED will reduce battery life significantly.

Choosing a Location to Mount the Station

Try to position your Leaf/Soil Station as follows:

• With the solar panel positioned for maximum exposure to the sun.

• Within transmission range of your Vantage Pro console.

• See “Range of Wireless Transmission” on page 8

• Within cable range of the sensors.

• Leaf Wetness Sensors come with 40’ (12 m) of cable standard and can be

extended up to 200’ (61m) using 6-conductor 26 AWG cable.

• Soil Moisture Sensors come with 15’ (4.6 m) of cable standard and can be

extended up to 1000’ (300m) using #18 gauge UF cable.

• Temperature Sensors come with 15’ (4.6 m) of cable standard and can be

extended up to 800’ (242m) using #24 AWG shielded cable or up to 1200’

(260m) using #22 AWG shielded cable.

Range of Wireless Transmission

The range of wireless transmission depends on many factors. For the best

reception, position the transmitter shelter and your console/receiver as close

together as possible.

The maximum range is up to 400' (120 m) in the line of sight, under optimal

conditions. Typical range under most conditions is 100' to 200' (30 to 60 m), but

this may be reduced by walls, ceilings, trees, foliage and radio-frequency

interference (RF). Cordless phones, baby monitors, and ham radios are

common examples of devices that can cause RF interference.

A metal roof or other large metal structure can interfere with the signal.

Aluminum siding, a furnace with metal ducts, and your refrigerator are

examples. Sometimes transmission between wireless units is obscured by

something you cannot identify, or by some obstacle that you can’t work

around. If necessary, consider using Wireless Repeater #7624 or #7625 to

strengthen the signal or increase the distance between the transmitter and the

console/receiver.

Mounting the Leaf/Soil Station Page 9

Testing Transmission from Proposed Location

It is very important to test reception from the proposed location before perma-

nently mounting the Leaf/Soil Station.

• Place the shelter at the intended mounting site, or have someone hold it

there, so you can walk around with the console/receiver for a few min-

utes. Rotating the antenna may help to improve reception.

• Test wireless reception anywhere you might want to use or mount your

console/receiver now or in the future. Take your time. If you aren’t pick-

ing up strong signals where you intend to place your console, better to

move the shelter now than after it has been mounted. Experiment.

• If you have irregular terrain in the area, it may interfere with the signal.

For example, if the transmitter is mounted downhill from the console/

receiver, the ground may block a wide angle of the transmitted signal.

Mounting the Leaf/Soil Station

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 will be

level.

2. Drill two more holes 7-1/32"

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

and bottom of the shelter into

the post.

4. Using an adjustable wrench or 7/16" wrench, tighten the lag screws.

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.

5. Put a flat washer, a lock washer, and a hex nut on each bolt end, and tighten

the hex nuts.

Note: If no soil temperature probe is used, the console will use a default temperature of

75ºF (24ºC) to compensate the soil moisture sensor readings.

6. To prevent fraying or cutting of cables,

secure them so they will not whip about in

the wind. Secure a cable to a metal pole by

wrapping electrical tape around them both.

Make sure cables are secure by placing clips

or ties approximately every 3 – 5' (1 – 1.6 m).

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.

Rules for Using Leaf, Soil and Temperature Sensors

The following station and sensor configurations are supported bythe Leaf/Soil

Station:

• If your station is configured as aLEAF/SOIL station in your Vantage Pro

console, the readings for a temperature sensor installed in TEMP 1 or

TEMP 2 will be displayed as both a leaf temp and a soil temp. A temper-

ature probe installed in TEMP 3 will only be displayed as a soil temp.

• A station configured as a LEAF station in the console will support two

leaf wetness sensors and two leaf temperature probes.

• Leaf temperature probes can be used as you wish to measure air, water,

or soil temperature. Leaf temperature does not affect leaf wetness read-

ings.

• A station configured as a SOIL station in the console will support three

soil moisture sensors and three soil temperature probes.
