A Few Notes About Remote Modem Connections
If you use a remote modem connection, WeatherLink will automatically dial the
station whenever you initi ate a program action that requires the software to talk
to the station .

While connected to a remote station, an “On-Line” icon appears in the toolbar.
This icon indicate s th at you a r e on-line and may be use d to h an g up a remote connection. To hang up, choose the On-Line icon from the toolbar or cho ose Hang Up
from the File menu.
By default, WeatherLink will hang up the connection to the modem after one
minute without any commu ni cat ion wit h th e stat ion . Use th e Serial Port dia log
box in the Setup menu of WeatherLink to change this default value. (See the
WeatherLink help files for more on this subject.)
Note: WeatherLink will not hang up the phone line if the bulletin, summary, or other windows
receiving real-time data from the console are active.
Local Connection for Vantage Pro
The instructions below explain how to make a typical local connection between
your Vanta ge Pro station and your computer.
Note: If you extend the cable run beyond 48’ (14.4 m), the software may have difficulty com-
municating with the station.
1. Enter the console’s Setup Mode by pressing and holding the DONE key,
then pressing the “DOWN arrow ” key.
Entering Setup Mode ensures that the station is not writing any data and
saves the current daily tota ls, highs, and lows to memory.

3. Carefully insert the data logger into the large receptacle jack marked
EXPANSION inside the battery compartment
Guide the data logger cable through the square slot below the receptacle.
CAUTION: Make sure that whenever you connect or disconnect the logger from the
console that the console is NOT powered up. Plugging or unplugging the
data logger while power is applied can lock up or damage the logger.
4. Restore power to the weather station by reinstalling the batteries and reattaching the power adapter, if present.
The weather station should beep three times; each beep should occur within
about one second of the others.
5. Replace the battery cover, ensuring that the data logger cable exits through
the square slot.
6. Locate a free serial port on the back of your computer and connect the blue
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 cons ole more than 8’ from t he 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.
