Connecting Original Weather Stations
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 for Original Weather Stations
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 reenter these values 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 bat-
tery backup.
Failure to remove power before installing the data logger may cause damage
to the data logger and/or console.
4. A small switch near the data logger cables controls the baud rate. The
default setting is 2400 baud. If you need to run at 1200 baud, change the set-
ting before connecting the data logger to the console.
