Connecting the Weather Station

2. Place the external modem in a location where it can connect to both the 

data logger and the phone jack. Do not turn the modem on at this time.

3. Remove the mounting base from the weather station.
4. Remove all power from the weather station by removing the power adapter 

and battery backup.

Note: Failure to remove power before installing the data logger may cause damage to the data 

logger and/or station.

5. A small switch on the data logger near the cables controls the baud rate. 

The default setting is 2400 baud. If you need to run at 1200 baud, change 
the setting before connecting the data logger to the console.

6. Connect the short data logger cable to the cable jack marked “Weather-

Link” on the bottom of your weather station console. 

7. Connect the Telephone Modem Adapter to the external modem.

The Telephone Modem Adapter (#7870) is required to use the data logger 
with a modem. A standard DB25 connector with a gender changer will not 
work. 

8. Connect the long data logger cable to the Telephone Modem Adapter.
