Refer to section 4.3.2 for changing the baud rate settings for the instrument.
Make sure that the instrument’s baud rate corresponds with the baud rate of the application the instrument is
communicating with, otherwise no communication can be established.
For RS232 communication, the maximum cable length is 10 m for baud rates up to 38400 Baud. For higher baud
rates, use cable lengths of maximum 3 m.
