Setting the DavisTalk Transmitter ID Page 5

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:
