Connecting the Weather Station
Connecting the Weather Station
The instructions below explain how to connect your Weather Monitor II,
Weather Wizard III, or Perception II weather station directly to your computer.
Note that if you extend the cable run beyond 48' (14.4 m), the software may
have difficulty communicating with the station.
Local Connection
1. Make a note of the barometric pressure, total rainfall, and (if applicable)
calibration numbers.
You must remove power from the weather station console to install the data
logger. Removing power will cause these stored weather values to be
erased. Use WeatherLink to re-enter these values, as well as the time and
date, after restoring power to the console.
2. Remove the mounting base from the console.
3. Remove all power from the console by removing the power adapter and
battery backup.
Failure to remove power before installing the data logger may cause dam-
age to the data logger and/or console.
