NZR DHZ 5 63 Professional MBus

Baud rates

The device does not automatically detect baud rate and at any given time supports only one speed (despite that the standard seems to expect that 300Bd is always supported). In my case the initial baud rate was 2400 Bd. This can be changed to any standard rate between 300 and 9600 by the MBus command.

In some documents there is mentioned that the rate is configurable - does it mean by the magnet?

Address

The address is also mentioned to be configurable, but how?
