Connecting With a PC 

Connecting with a PC allows you to configure and troubleshoot your 

transmitter using serial line commands. For a list of commands, see 

section List of Serial Commands on page 41. 

When connecting using a PC, use the Vaisala USB cable (Vaisala order 

code 219690) and a suitable terminal application: 

-  If you have not used the Vaisala USB cable before, install the driver 

before attempting to use the cable. Refer to section Installing the 

Driver for the USB Service Cable on page 38 for detailed instructions. 

-  For more information on using a terminal application, see section 

Terminal Application Settings on page 39. 

Installing the Driver for the USB Service Cable 

Before taking the USB service 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 service 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 service 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 

Programs and Features

 menu in the Windows Control Panel. 

In Windows XP and earlier Windows versions the menu is called 

Add or 

Remove Programs.
