Installing the Driver for the USB Cable
Before taking the USB cable into use, you must install the provided USB
driver on your PC. When installing the driver, you must acknowledge
any security prompts that may appear.
1. Check that the USB cable is not connected. Disconnect the cable if
you have already connected it.
2. Insert the media that came with the cable, or download the latest
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. The reserved ports are also visible in the
Ports section of the Windows Device Manager.
Remember to use the correct port in the settings of your terminal
program. Windows will recognize each individual cable as a different
device, and reserve a new COM port.
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 Programs and Features menu in the Windows Control Panel.
In Windows XP and earlier Windows versions the menu is called Add or
Remove Programs.
