? Why can't the WeatherLink Software “communicate” with the WeatherLink?
If you are experiencing difficulty establishing communication between the
weather station and the WeatherLink Software, start by checking the weather
station's own diagnostics. To do this, you must remove all power to the
weather station and then restart the weather station by restoring power (with
the WeatherLink still attached). You should hear three beeps, each of which
occurs when the weather station passes one of its diagnostic tests. The first
beep occurs after approximately one second, the second after approximately 8
seconds, and the third after approximately 22 seconds. If you do not hear one
or more of these beeps, contact Davis Instruments at 510-732-7814.
If you hear all three beeps, see “Finding the Correct Serial Port” on page 12 for
instructions on checking you standard serial ports. If this identifies a serial
port other than the one you selected in station setup, try connecting to the
WeatherLink again.
If you still cannot connect or if the loopback test identifies the serial port you
already have selected, attempt to eliminate the following possibilities. If you
have questions on how to proceed, it is recommended that you contact your
PC vendor or PC technical support.
▲ You have a hardware device conflict.
▲ Your serial port uses a non-standard IRQ line.
▲ Your serial port is defective.
▲ The loopback connector or the WeatherLink adapter plug is bad.
? How do I select the correct serial port?
If you can use the serial port in question with another program, simply deter-
mine the serial port to which that program is set. Otherwise, see “Finding the
Correct Serial Port” on page 12 for instructions.

? Why are the readings on my station and the WeatherLink Software different?
The calibration numbers for the weather station and software may not agree.
Make sure you set all calibration numbers from the software. See “Calibration
Numbers” on page 93 for further explanation.
