Connecting With a Computer
Connecting with a computer 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 37.
When connecting using a computer, 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 34 for detailed instructions.
- For more information on using a terminal application, see section
Terminal Application Settings on page 35.
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 computer (requires Windows).
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 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 cable as a different device, and
reserve a new COM port. Remember to use the correct port in the
settings of your terminal program.
