WeatherLink
®
for Alarm Output
Addendum
Introduction
This Streaming Data Logger is designed to provide an electrical interface
between a Vantage Pro2™ , Vantage Vue
® , or Vantage Pro ® weather sta-
tion console or Weather Envoy™ and an electrical device. You may set a
series of thresholds for various parameters that will trigger if any of them
are met (OR condition), all of them are met (AND condition), one and only
one is met (XOR condition). You may also test whether a parameter is
within (between condition) or outside of (not between condition) a certain
range, or changing at a certain rate (trending), or how far apart (or close)
two like parameters are from each other. Finally, you may also test various
parameters to see if they are reporting a valid number. This can be used to
signal a bad data connection or malfunctioning sensor.
This product also contains the functionality of the WeatherLink for Van-
tage Pro2 Serial version. Please consult the WeatherLink for Vantage Pro2
Getting Started Guide and on-line Help files for information on the use of
the WeatherLink program (including its hardware requirements and typical
installation), package contents, and optional accessories for this product.
If you plan to install this product in a Vantage Pro2 or Vantage Pro console,
use the notch in the battery door located adjacent to where the PC connec-
tor protrudes and above the AC power connector to bring out the Connec-
tor Block wire.
If you plan to install this product in a Weather Envoy, it is recommended
that you knock out the left-most tab with the Weather Envoy's PC connec-
tor facing you and loop the Connector Block wire around the data logger
connector to the Weather Envoy and bring it out where this tab was
removed.
