Fig. 18 NK8000 serial configuration for MM8000 / MK8000
Note: Not all subsystems are configurable for MK8000. See section 3.1 for details.
System architecture
This configuration allows for integration of a number of Cerloop (proprietary Class A
loop), Cerban and/or RS485 connectable control panels. In addition it allows for
Guarto (CS6) integration via LON-bus. One of the NK822x Serial Ports provides the li-
aison for a local management station (MM8000 / MK8000).
Communication / connection
The NK822x is connected on upstream side via RS-232 (proprietary CMSDL protocol)
to the management system.
Note: A (temporary) Ethernet network link is required for configuration download.
On the downstream side, the NK822x is connected via serial lines and/or via LON-bus
to a number of different fire & security control units.

For supported downstream configurations/protocols of NK822x, please refer to the
NK822x-Ethernet Port datasheets. (See "Reference documents page 6.)
