Connecting AWS Client to AWS330 
Installing USB Driver 
If you are using a computer that does not have a RS232 serial port, such 
as most laptops, a USB to RS232 converter cable is provided for using a 
local connection to the AWS330 system. Install the driver for the cable as 
follows: 
1. Insert Vaisala USB Instrument Driver CD to CD/DVD drive of 
your PC. 
2.  If the installation program is not started automatically, start it from 
the CD root directory, program setup.exe. 
3.  Follow the instructions given by the installation program. 
4.  When the driver installation is complete, connect the USB cable to 
a free slot on your PC. Allow the operating system to detect the 
driver for the cable automatically. 
5.  To check which port has been assigned for the USB serial port, 
launch program Vaisala USB Instrument Finder from the Start 
menu.
