There are two basic types of installations: direct connection and phone modem
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.

The required hardware differs depending on whether you are attempting to make
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™ 3.1, 95, 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.
▲ 4MB RAM
▲ Windows-Compatible Display
VGA (16 Colors) minimum. SVGA (256 Colors) recommended.
▲ One Free Serial Port
▲ Fax Modem
A fax modem is required to take advantage of the software’s AutoFax feature
(see ”Auto Fax” on page 32). If you do not plan to use the AutoFax feature, a
fax modem is not required for a direct connection.
Phone Modem Connection Hardware Requirements
In addition to the provided hardware, the following hardware is required for a
phone modem connection.
▲ Computer running Windows™ 3.1, 95, or NT 4.0 with at least 5 MB of free disk
