2 Introduction
This section provides a description of an NK8000 system and its components.
2.1 NK8000 system overview
The NK8000 family provides LAN/WAN adapter products for a safety and security
network, which is based on TCP/IP, BACnet/IP, and Ethernet standards. It works
together with Siemens Danger Management Systems (DMS) to manage distributed
safety and security units.
The NK8000 family includes:
 NK8222 Ethernet port: LAN/WAN (CMSDL/IP, CEI-79) and Dial-up (CEI-79)
communication unit supporting one subsystem connection over RS232 line or
CerCom/LON bus, and locally connected DF8000 I/O units. It can provide local
interactions between points in the connected subsystem and I/O.
 NK8223 Ethernet port: LAN/WAN (CMSDL/IP, CEI-79) and Dial-up (CEI-79)
communication unit supporting up to 4 RS232 lines, one CerCom/LON bus, and
locally connected DF8000 I/O units. It can provide local interactions between
points in the connected subsystems and I/O.
 NK8225 Ethernet port: LAN/WAN (BACnet/IP, CMSDL/IP, CEI-79) and Dial-up
(CEI-79) communication unit supporting up to 4 RS232 lines, one CerCom/LON
bus, and locally connected DF8000 I/O units. It can provide local interactions
between points in the connected subsystems and I/O.
 NK8231 CEI Interface for a single subsystem: LAN/WAN/Dial-up (CEI-79)
communication unit supporting one subsystem connection over RS232 line as
well as onboard I/O and locally connected DF8000 I/O modules.
Note: NK8231 is intended for use with MM2000 Management Stations, which
are only available in the Italian market.
 NK8232 Ethernet port (single): LAN/WAN (BACnet/IP, CMSDL/IP, CEI-79) and
Dial-up (CEI-79) communication unit supporting one subsystem connection over
RS232 line as well as onboard I/O and locally connected DF8000 I/O modules.
It can provide local and network-wide interactions affecting points in the con-
nected subsystems and I/O. In addition, it can act as Modbus Gateway for
FS20/FS720.
 NK8235 Ethernet port: LAN/WAN (BACnet/IP, CMSDL/IP, CEI-79) and Dial-up
(CEI-79) communication unit supporting up to 4 RS232 lines as well as onboard
I/O and locally connected DF8000 I/O modules. It can provide local interactions
between points in the connected subsystems and I/O. In addition, it can act as
Modbus Gateway for FS20/FS720.
 NK8237 Modbus Gateway for Sinteso (or Cerberus PRO) fire detection systems
supporting a network connection with the fire system and a network or serial
connection to a Modbus client/master.
Note that NK823x units with build state up to 04 are equipped with the
NKM8001-A1 mainboard that do not support locally connected DF8000 I/O
modules.
Instead, NK823x units with build state 10 or higher are equipped with the
NKM8001-A2 mainboard that can support up to 4 locally connected I/O mod-
ules.
