for Macintosh OS X. The
WeatherLink software and data logger allow you to connect your Apple
Macintosh computer running OS X to a Davis weather station so you can
store, view, plot, analyze, export, print, and put on the Internet the weather
data collected by your station.

Before continuing, please make sure your WeatherLink package contains
the following listed items:
• USB Data Logger
•8
' (2.4 m) cable with connector to link your station to your computer.
• WeatherLink software CD ROM
Hardware Installation
You can connect a computer directly to your weather station using the
WeatherLink data logger (local connection), or you can connect a computer
to a remote weather station using a phone modem (remote connection).
Requirements and installation for each type of connection differ, and are
explained separately below.
Hardware Requirements
The hardware requirements for local and remote connections are listed
below.
Local Connection Hardware Requirements
In addition to the provided hardware, the following are required for a
direct connection.
• Macintosh computer running OS X v10.1 or newer with at least 5 MB of
free disk space.
The amount of space necessary for the data files depends on the archive
interval. 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.
• One free USB port
