The instructions in this section describe how to connect a computer to the
MMT310 using the PuTTY terminal application for Windows (available
for download at www.vaisala.com). Perform the necessary cabling and
configuration of the transmitter before following the instructions.
Opening a Serial/USB Connection with PuTTY
1. Power up the MMT310 and start the PuTTY application.
2. Select the Serial & USB settings category, and check that the
correct COM port is selected in the “Serial or USB line to connect
to” field. Change the port if necessary.
If you are using a Vaisala USB cable, you can check the port that it
uses by clicking the USB Finder... button. This opens the Vaisala
USB Instrument Finder program that has been installed along with
the USB drivers.
3. Check that the other serial/USB line settings are correct for your
connection, and change if necessary.
