Connecting with a Computer
Connecting with a computer allows you to configure and troubleshoot
your probe using serial line commands. For a list of commands, see
section Serial Commands on page 28.
When connecting using a computer, use the Vaisala USB cable (Vaisala
order code 221040) 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 below for detailed instructions.
- For more information on using a terminal application, see section
Terminal Application Settings on page 27.
Installing the Driver for the USB Service Cable
Before taking the USB service cable into use for the first time, you must
install the provided USB driver on your computer (requires Windows).
When installing the driver, you must accept 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. Run 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 computer. 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 service cable as a different
device, and reserve a new COM port. Remember to use the correct port
in the settings of your terminal program.
