The logical BACnet address of NK822x is fixed to 1. This address has to be con-
figured in the CS6 Guarto using the tool SWE6 for Guarto MP3 (Node CerCom Bus,
properties of node Management Station).
Note: The physical LON addresses and the logical BACnet addresses must be unique
in a LON-network.
Guarto MP2b is no longer supported in NK8000 MP3.15 and higher.
4.1.6 Ethernet interface
The NK822x main board is equipped with one Ethernet interface and an RJ-45
