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.
