The Connector Block is designed to allow you to turn heaters, fans, and other devices on or off using the data from
your weather station. The utility software steps you through the choices. For each of four outputs, you can enter up
to eight different weather parameters. Enter threshold values for each, select from nine different test conditions, and
logically combine the entries together as you choose. Our connector block provides the interface between your
Vantage Pro2 console or Weather Envoy and an electrical device. For high-power devices, you may also need to add
electrical relays (not supplied by Davis Instruments).

In addition to the requirements for WeatherLink, the Irrigation capability has the following additional hardware
requirements.
requirements.
• Computer running 98, 98SE, ME, 2000, XP, or Vista with Microsoft .NET 2.0 framework. Requires at least
3 MB of RAM and 512 KB of hard disk space.
• Relays: You may need to obtain your own relays in order to switch equipment at voltages higher than
28 volts or power levels above 10 Watts.
Caution:
The Alarm Output data logger is not suitable for any use in which the health or safety of any person or the value or pro-
tection of valuable property is dependent on the operation of the device.
