The instructions below describe how to connect to the MMT330 using
the PuTTY terminal application for Windows. Perform the necessary
cabling and configuration of the transmitter before following the
instructions.
PuTTY is available for download at www.vaisala.com .
NOTE PuTTY cannot be used to access the transmitter through the User Port if
the transmitter is configured to use the Modbus protocol. However, you
can always use PuTTY to access the transmitter through the Service Port.
Opening a Serial/USB connection
1. Power up the MMT330 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. The default settings (shown in
Figure 55 on page 90) are used by the Service Port of the
MMT330.
