After the driver has been installed, connect the USB service cable

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

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.

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.
