• (Optional) Relays: You may need to obtain relays in order to switch
equipment at voltages higher than 28 Volts or power levels above 10
Watts. Not available from Davis Instruments.
Note: Due to its normal operation, this product will draw more current from the console and Envoy than
in typical use. Davis recommends you use the power adapter provided with your product if you
are concerned about battery life. Additionally, you can optimize battery life by setting your outputs
to normally open, particularly those you do not plan to use.

Software Installation and Setup
Installing the Software
Follow the installation instructions for WeatherLink. This will also install the
configuration software. The install file contains this program as well as Weath-
erLink if you ever need to install the program manually.
Running the Configuration Software
To run the configuration software, double-click on the Streaming Data Utility
icon in the Streaming Data Utility directory of the WeatherLink directory or
select the Streaming Data Utility from the Start Menu under the WeatherLink
directory.
Finding the Correct Serial Port
The configuration software includes a procedure for locating the serial port to
which your streaming data logger is connected.
Use the Serial Port Settings dialog
box to select the correct COM port
and baud rate to communicate to
the streaming data logger. The cor-
rect baud rate will be the one set in
your Vantage console, and in
WeatherLink. The default value is
19200 baud. You may manually
set the COM port setting or use the
Auto Detect button to automati-
cally find where your streaming
data logger is connected.
Note: If you have more than one streaming data logger connected to your system, it is highly recom-
mended that you manually set the Com Port and Baud Rate.
