WeatherLink
WeatherLink for Emergency Response Teams with Streaming Data
Logger (6550)
The Streaming Data Logger is designed for use with the free CAMEO
®
software developed by National Oceanic and
Atmospheric Administration (NOAA) and the Environmental Protection Agency (EPA). It provides the real-time
weather data needed to map the "footprint" of a hazardous plume, predict its dispersion, and help make critical public
safety decisions. Please note that this product is specifically designed to work with the ALOHA
®
software program
and will not work with other such programs of this type. For further and more detailed information on this product,
please visit the following website:

Note: CAMEO, or Computer-Aided Management of Emergency Operations, is a suite of three integrated software applications, including ALOHA
®
Areal
Locations of Hazardous Atmospheres.
Hardware Installation and Requirements
In addition to the WeatherLink requirements, the streaming data capability has the following additional hardware
requirements:
• Computer running any version of Windows™ with at least 1 MB of RAM and 2.5 MB of hard disk space
Streaming Function Specifications
Time Out Period: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .The streaming data logger utilizes a time-out period for ceasing
streaming whenever software attempts to communicate to the logger.
Once communications to WeatherLink are initiated and successful,
the streaming data logger will be unable to communicate with the
Streaming Data Utility until the Time Out Period expires.

WeatherLink for Irrigation Control with Connector Block (6560)
The connector block is designed for use with most common irrigation systems, including Rain Bird, Rain Master,
and Toro. For the industrial controllers used in agriculture and turf management, it provides electronic pulses for
wind, rain, and evapotranspiration (ET). Homeowners can add our optional Solar Radiation Sensor to turn the system
on or off based on evapotranspiration. All users can use the alarm settings in the Vantage Pro or Pro2 console or
Weather Envoy to inhibit the irrigation cycle based on weather conditions. The device will inhibit the irrigation cycle
if ANY of the alarms are active.
Hardware Installation and Requirements
In addition to the requirements for WeatherLink, the Irrigation capability has the following additional hardware
requirements.
• Computer running any version of Windows™ with at least 3 MB of RAM and 512 KB of hard disk space.
• Industrial Irrigation Controller with inputs for wind, rain, and/or ET; or a Residential Controller with a Common
or a Rain Sensor connection. Irrigation wire as appropriate to your Irrigation Controller
• Solar Radiation Sensor, P/N 6450 to use evapotranspiration (ET) to control the irrigation cycle. In addition to the
