Terminal Application Settings
The steps below describe how to connect to the HMP155 using the
PuTTY terminal application for Windows (available for download at
www.vaisala.com ) and the USB serial interface:
1. Connect the USB serial interface cable between your PC and the
RS-485 port of the HMP155.
2. Start the PuTTY application.
3. 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.
4. Check that the other serial settings are correct for your connection,
and change if necessary. Refer to Table 5 on page 24 for the default
serial line settings of the HMP155.
5. 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.
6. 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.
