The MSB is of no relevance!
The standard value 19,200 bit/sec (0x04) is recommended for the transmission rate.
Make sure that the same transmission rate is selected for the fan as for the master (e.g. EC Control).
Otherwise, communication with the fan will not be possible!
If the value set by the customer (holding register D249) or the factory default setting (holding register D2C9)
differ from the value selected here, ensure that the transmission rate is also changed after data transfer from
the customer setting or factory default setting (see 2.5 and 2.6). No communication is then possible with the
previous setting
