WeatherLink allows two types of installation: direct connection and phone
modem connection. Direct connection means connecting the computer directly to
the station. Phone modem connection refers specifically to any installation where
the station is connected to a modem and you communicate with the station and
data logger via a modem at your computer. Requirements and installation for
each type of connection differ, and are explained separately below.

The required hardware differs depending on whether you are making a direct
connection or a phone modem connection.
Direct Connection Hardware Requirements
In addition to the provided hardware, the following are required for a direct con-
nection.
▲ Computer running Windows™ 95, 98, 2000, ME or NT 4.0 with at least 5 MB of free
disk space
The amount of space necessary for the data files depends on the archive inter-
val. Database files containing data stored at a 30 minute archive interval
require approximately 36K of disk space per month of data. The file size
changes in a linear fashion depending on the archive interval. For example,
data stored at a 1–minute interval requires approximately 1 MB/month while
the data stored at a 2–hour interval requires approximately 9K/month.
