2 Introduction
The NK8000 family provides LAN/WAN adapter products for a safety and security
network:
 The NK822x series (phased out).
 The NK823x series.
 The NK8237 Modbus Gateway.
The
NK822x series 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, as well as network-wide over
other NK8225s or NK823xs.
The
NK823x series includes:
 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 interactions between points in the connected subsystems
and I/O, as well as network-wide intearctions over other NK8225s or NK823xs. In
addition, it can act as Modbus Gateway for FS20/STT20/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, as well as network-wide
interactions over other NK8225s or NK823xs. In addition, it can act as Modbus
Gateway for FS20/STT20/FS720.
Note: The Modbus host interface is discussed in the NK8237 Modbus Gateway ICC
manual, (document A6V10316241). This document should be used for configuring the
Modbus host also on NK8232 and NK8235.
