Terminal Program Settings

The default settings of the MMT162 serial interface are presented in

Table 4 on page 23. If the settings of your MMT162 have been changed

and you do not know what they are, refer to section Unknown Serial

The steps below describe how to connect to the MMT162 using the

PuTTY terminal application for Windows (available for download at

) and a USB serial interface cable:

Connect the USB serial interface cable between your PC and the

RS-485 port of the MMT162 (port 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.

Note: 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.

Note: 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 set the Local echo setting to Force on 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.
