Accessing serial line command interface from
analog or Modbus mode
Follow the steps below to connect to the serial line when the probe is in analog or Modbus
mode. You can also use the procedure to retrieve the communication settings of your device, if
you do not know them. You must use the Vaisala USB cable (Vaisala item code 219690) in this
case.
1. Connect the USB cable to the PC and install the driver, if necessary. Do not connect the
cable to the probe yet.
2. Open the terminal program and open a connection to the corresponding COM port using
the default settings 19200, 8, N, 1, no flow control.
3. Select the Serial settings category, and check that the Serial line to connect to field
contains the correct COM port.
To check which port the USB cable is using, select Start > Vaisala > Vaisala USB
Instrument Finder.
4. To open the connection window and start using the serial line, select Open.
5. Keep the ENTER key pressed down and connect the other end of the USB cable to the
probe. This causes the probe to start in RS-485 mode, using the default serial settings.
You can now use the probe with the terminal program.
