DAVIS Vantage Pro2 Manual

Welcome to the Weather Envoy!
The Davis Instruments’ Weather Envoy
®
provides a way of getting weather data
from your Vantage Pro2
™
or Vantage Vue
weather station into your Windows XP,
Vista, or 7; or Macintosh (OS X) computer
using our WeatherLink
®
software.
The Weather Envoy includes the data
collection and logging functions of the
Vantage consoles, but in a smaller package
that can be placed next to your computer, or
in a field installation. It can be used to free your wireless console from the
need to be near the computer, or it can be used in place of either a wired or
cabled console. Both cabled and wireless versions are available. Used with our
WeatherLink software and data logger, the Weather Envoy allows you to view,
store, plot, analyze, export, share, and print your weather data.
