MENNEKES: default communication settings

Factory defaults as the manufacturer documents them. Change one setting at a time on site and write down what you changed. Word order applies to 32-bit values; the addressing column says how the manufacturer prints register numbers (every map on this site also gives the 0-based wire address).
