The steps below describe how to connect to the transmitter using the PuTTY terminal
application for Windows and a USB computer connection cable.
1. If you have not used the Vaisala USB cable before, install the driver before attempting to
use the cable.
2. Connect the USB cable between your computer and the transmitter's service port.
3. Start the PuTTY application.
4. Select Connection > Serial & USB and check that the correct COM port is selected in the
Serial or USB line to connect to field. If you are using the PuTTY terminal application
supplied by Vaisala, you can press the USB Finder button to open the Vaisala USB
Instrument Finder program.
5. Check that the other serial settings are correct for your connection, and change if
necessary. Flow control should be set to None unless you have a reason to change it.
6. Select Terminal. Use the following settings:
•
Local Echo
Select Force on. This setting ensures that your typing is shown on the session
window.
•
Send line ends with line feeds (CR+LF)
Make sure this option is not selected. Enabling line end sending with line feeds
can cause issues with the terminal connection.
