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 Installation
1. Find the weather station console that will receive the WeatherLink serial
connection.
2. For consoles only: Enter the console's Setup Mode by pressing and hold-
ing DONE, then pressing 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 and remove the batteries and AC-power adapter,
if present.
Note: Failure to remove power to the console or Weather Envoy before installing the data log-
ger may cause damage 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.
