The instructions below explain how to make a typical phone modem connection.

Typical Phone Modem Installation

The illustration below shows a typical phone modem connection. This involves
connecting the WeatherLink to the weather station and to a modem at the station
console site and connecting your computer's modem to a phone line, which will
allow you to "dial" the weather station.

Phone Modem Installation Instructions

1. Install and set up an internal or external modem (according to the instructions supplied
by the manufacturer) for use with your computer.
Make a note of the COM port and IRQ used by the modem. You will need this
information when entering serial port settings for the station (see "Serial Port"
on page 20).
2. At the station console site, position the external modem in a location where it can con-
nect to both the WeatherLink and a phone jack and plug it into the phone jack. DO NOT
TURN THE MODEM ON AT THIS TIME.
The cable which connects the WeatherLink to the modem is 8 feet (2.4 m) long.
If you need to mount the station console more than 8 feet from the modem,
use a 40' (12 m) standard 4-conductor extension cable. Do not attempt to use
more than 40' of extension cable, or the WeatherLink may have difficulty
"communicating" with the modem. If you need to mount the station console
farther away, you will need to use the Short-Range Modem Pair.
3. Plug the external modem into the phone jack.
