Terminal Application Settings for Probes
in Analog Mode
Follow the steps below to connect to the serial line on probes that have
been ordered with analog outputs. You must use the Vaisala USB cable
in this case.
1. Start the PuTTY application.
2. Connect the USB serial interface cable to your PC. Do not connect
the other end to the probe yet.
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 set to the default settings of
the probe. Refer to Table 5 on page 30.
5. Click the Open button to open the connection window and start
using the serial line.
6. Connect the other end of the USB cable to the probe, and
immediately press the Enter key a few times. This will cause the
probe to start in RS-485 mode, using the default serial settings.
