WeatherLinkIP™ for

®

Vantage Pro

WeatherLinkIPTM for Vantage Pro® and Vantage Pro2™ consists of our WeatherLink software
and a specialized data logger that connects to a Vantage Pro or Vantage Pro2 console or Weather Envoy to a ethernet
connection. The software and data logger transfer your Vantage Pro or Vantage Pro2 weather data to your computer,
allowing you to create a permanent weather database. Once stored in the database, your weather information can be
used to generate a wide variety of reports and graphical displays.

In addition, the WeatherLinkIP data logger automatically uploads your console or Envoy information to a web server
provided by Davis Instruments that lets you see your weather data via the Internet without having to set up your own
web page. Your weather data is automatically saved to Davis’s web servers which provide four times the storage of
the data logger. Using the WeatherLinkIP data logger lets you become part of the WeatherLink Network, a
collection of websites containing customer weather information that is stored on a server owned by Davis
Instruments. Being part of the WeatherLink Network and having a site on WeatherLink.com means you are part
of a community of weather enthusiasts who use the WeatherLink Network to view their own weather data and
share that weather data with friends and people across the world quickly and easily.

WeatherLink Software Features

• Displays the current weather station data in a real-time “bulletin” on the computer.

• Allows you to set and clear data in the weather station console (time and date, highs and lows, alarm
thresholds, calibration numbers, etc.) from the computer.

• Graphs archived weather data on an hourly, daily, weekly, monthly, or yearly basis.

• Generates Weather Watcher reports in the National Climatic Data Center (NOAA) format.

• Collects data from multiple weather stations on the same computer.

• Includes support for GLOBE, an international weather-related science program for students from
elementary through high school. Visit www.globe.gov for more information.

• APRS data protocol allows volunteers in the Citizen Weather Observer Program (CWOP) to send real­time weather data to the National Weather Service. CWOP is data used for weather education and
research projects. Visit www.wxqa.com for more information.

• Gives you multiple options for connecting to your WeatherLinkIP data logger.

Software Specifications

Software System Requirements

A network or ethernet connection. Computer running Windows™ 98 SE, Windows 2000, XP or Vista with Microsoft
.NET 2.0 framework. The amount of disk space necessary for the data files depends on the archive interval. Each
archive record in the database is 88 bytes. Every day in the database has an additional two records totalling 176 bytes
that store daily summary information. A database containing data stored at a 30-minute archive interval requires 132
KB of disk space per month. The file size changes in a linear fashion depending on the archive interval. For example,
data stored at a one-minute interval requires approximately 3.9 MB a month while the data stored at a two-hour
interval requires approximately 33 KB a month.
