• Hardware device conflict—Check the Device Manager tab in the
Windows System Properties dialog box to ensure that Windows recog-
nizes the selected COM port. Consult your computer's documentation to
see how to access the System Properties dialog box.

Note: See the WeatherLink Online Help if you are troubleshooting a Modem connection.
Troubleshooting USB Communication
• Close the WeatherLink software.
• Disconnect the USB cable from the Envoy.
• Plug the cable back into the Envoy.
• Open the WeatherLink software again.
• Open the Communications Port dialog box. Select USB if USB is not
selected in the communications field and follow the prompts.
• Click Test to verify communication between the station and the software.
If the test is unsuccessful, either the station is malfunctioning or the drivers
for communicating with USB have not been installed successfully. To
verify that the driver is installed, look in Windows' System Properties ->
Device Manager -> Universal Serial Bus Controllers and see if the
USBXpress Device is listed. If the driver is listed and there is still no
communication between the station and the computer, call Technical
Support. If the drivers are not listed, contact Technical Support for
instructions on installing the necessary drivers.
• If you are using a third party application that requires the USB connection
to emulate a com port connection, see WeatherLink Online Help for more
information or contact Technical Support.
