Typical Phone Modem Installation

6. Locate a free serial port on the back of your computer and connect the DB9 to the port.
7. Insert the cable plug at the end of the short cable coming from the data logger into the
receptacle on the end of the 8’ cable. Then insert the cable plug on the end of the 8’
cable into the DB9 adapter.
The cable connecting the data logger to the computer is 8’ (2.4 m) long. If you
need to place the station console more than 8’ from the computer, use a 40’ (12
m) standard 4-conductor extension cable. Do not attempt to use more than 40’
of extension cable, or the data logger may have difficulty communicating with
the computer.
Note:
You do not need to keep the console connected to the computer for the logging to work. You
can connect the cable to the computer when you’re ready to download, then disconnect it if
you want to place the console somewhere else. However, you can only run WeatherLink’s bul-
letin, summary, or real-time strip charts if the console is attached to the computer.
8. Check the Baud rate settings on the console.
Enter the console SETUP mode by pressing and holding the DONE key, then
pressing the DOWN arrow key. Use the BAR and DONE keys to scroll to the
Baud Rate screen. The Baud Rate setting here on the console must be same as
that set in the WeatherLink software. Use the UP and DOWN arrow keys to
change the baud rate setting, if needed. Press and hold DONE to return the
console to current weather mode.

The illustration below shows a typical phone modem connection. This involves
connecting the data logger 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.
