Note!
When using the DIP switches 5 ... 6 for setting the baud rate, this baud rate applies for the
HART protocol as well as the Modbus protocol. Alternatively you may set the baud rate
using the configuration software (see chapter 5.5.3, see chapter 5.5.4). Via software it is
possible to set the baud rate separately for HART and Modbus.
