Why can't the WeatherLink software communicate with the data logger and station?
If you are having trouble establishing communication between the weather
station and WeatherLink, start by checking the weather station's own diagnos-
tics. Remove all power to the weather station and then restart it by restoring
power (with the data logger still attached).
Note:
The data logger uses non-volatile memory, so you won’t lose any data you’ve already
recorded. However, make sure to put the console in Setup Mode (by pressing and holding
the DONE key, then pressing the DOWN arrow key) before removing the batteries. This
ensures the station will not try to write any data as the power goes off.
▲
You should hear three beeps, each of which occurs when the weather
station passes one of its diagnostic tests. Each beep follows the
previous after about one second. The first beep tells you the processor
is running. The second beep will be for the logger (if installed) and the
third beep is for the display. If you do not hear one or more of these
beeps, contact Davis Instruments at 510-732-7814. (You’ll only hear two
beeps if you don’t have the data logger installed.)
▲
If you hear all three beeps, See “Finding the Correct Serial Port” on
page 11 for instructions on checking your standard serial ports. If this
identifies a serial port other than the one you selected in station setup,
try connecting to the data logger again.
▲
Make sure you are using the blue serial port adapter supplied with
WeatherLink for Vantage Pro. The older, black Davis serial adapters
will not work.
▲
Check the Baud Rate setting on the console and in the serial port dialog
box in the software. Make sure they’re set to the same number.
Note:
Enter the console’s Setup Mode by pressing and holding the DONE key, then pressing
the DOWN arrow key on the console. Scroll through the setup choices by pressing
the BAR or DONE keys until you reach the Baud Rate screen. This screen only
appears if the data logger is plugged into the console.
If you still cannot connect or if the loopback test identifies the serial port you
already have selected, eliminate the following possibilities. If you have ques-
tions on how to proceed, contact your PC vendor or PC technical support.
▲
You have a hardware device conflict.
Check the device manager tab in the Windows® system properties dialog
box to ensure that Windows recognizes your COM port. Consult your pc’s
documentation to see how to access the system properties dialog box.
