The following steps describe how to connect to
DMT152 using the PuTTY terminal application for Windows (available for download at www.vaisala.com/software) and a USB serial interface cable:
-
Connect the USB serial interface cable between your PC and the RS-485 port of DMT152
(connector II).
-
Start the PuTTY application.
-
Select the Serial settings category, and check that the correct COM port is selected in the Serial line to connect to field.
| You can check which port the USB cable is using with the Vaisala USB Instrument Finder program that has been
installed in the Windows Start menu. |
-
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.
-
Click the Open button to open the connection window and start using the serial line.
If PuTTY is unable to open the serial port you selected, it will show you an error message instead. If this happens, restart PuTTY and check the settings.
-
You may need to adjust the Local echo setting in the Terminal category to see what you are typing on the serial line. To access the
configuration screen while a session is running, click the right mouse button over the session window, and select Change Settings... from the pop-up menu.
