Serial Port Hardware Installation
A serial port connection can be installed so that WeatherLink uses a direct, local
connection between the computer and console, or so that WeatherLink uses a
modem connection to a remote weather station. Installation for each connection
type differs, and is explained separately below.
Local Connection
The instructions below explain how to make a typical local connection between
your Vantage Pro console and your computer.
Local Connection Installation
Complete the local serial port connection using the figure and instructions:
1. Find the weather station console receiving the WeatherLink serial
connection.
2. Enter the console’s Setup Mode by pressing and holding DONE, then press-
ing the down arrow (-) key. Entering Setup Mode ensures that the station is
not writing any data and saves current daily weather information to memory.
3. Remove the battery cover from the console back and remove all power by
removing the batteries and AC-power adapter, if present.
Note: Failure to remove power to the console before installing the data logger may cause dam-
age to the data logger or console. Plugging or unplugging the data logger while power is
applied can lock up or damage the logger.
4. Carefully insert the data logger with serial connector into the receptacle
marked EXPANSION inside the battery compartment.
