The following steps describe how to connect to digital probes using the PuTTY terminal application for Windows (available for download at www.vaisala.com/software) and the USB serial interface.
If you have an analog probe, you can still connect to the serial line by following the instructions in Accessing serial line command interface from analog or Modbus mode.
If the probe is in Modbus mode, to access the serial port command interface, follow the instructions in Accessing serial line command interface from analog or Modbus mode.
