NSTALLATION

connection. Direct connection involves connecting the computer directly to the
WeatherLink. Phone modem connection refers specifically to any installation
where the WeatherLink is connected to a modem and you communicate with the
WeatherLink via a modem at your computer. Requirements and installation for
each type of connection differ, and are explained separately below.
