2. Insert the media that came with the cable, or download the driver

from www.vaisala.com.

3. Execute the USB driver installation program (setup.exe), and

accept the installation defaults. The installation of the driver may

take several minutes.

4. After the driver has been installed, connect the USB cable to a USB

port on your PC. Windows will detect the new device, and use the

driver automatically.

5. The installation has reserved a COM port for the cable. Verify the

port number, and the status of the cable, using the Vaisala USB

Instrument Finder program that has been installed in the

Windows Start menu.

Windows will recognize each individual cable as a different device, and

reserve a new COM port. Remember to use the correct port in the

settings of your terminal program.

There is no reason to uninstall the driver for normal use. However, if you

wish to remove the driver files and all Vaisala USB cable devices, you

can do so by uninstalling the entry for Vaisala USB Instrument Driver

from the Add or Remove Programs (Programs and Features in

Windows Vista) in the Windows Control Panel.
