Which NK8000 Ethernet Port to choose?

1.2.1.1 NK82xx standard connectivity capabilities and common features

Building Technologies
CPS Fire Safety
NK8000 connects various subsystems via TCP/IP or BACnet/IP over Ethernet or serial
connectivity with the MM8000 and the MK8000 systems.
The following make up the NK8000 product family:
· NK823x (second generation of NK8000 Ethernet Ports):
- NK8232 Ethernet Port for a single subsystem for DMS8000 systems
- NK8235 Ethernet Port for DMS8000 systems
- NK8237 Modbus Gateway for Sinteso and Cerberus PRO fire detection sys-
tems
The NK82xx Ethernet Ports are used to connect local and distributed safety and secu-
rity devices to DMS8000 Management Stations. The Ethernet Port provides a first
level of centralisation, and acts as a secure communication partner for DMS8000. All
ports come with optional housing solutions with autonomous power supplies.
NK823x, including the products NK8232, NK8235, and NK8237, is the second genera-
tion of Ethernet Ports. NK823x is based on a new more powerful HW platform and can
replace the NK822x products. NK8232 is backward compatible with NK8222, and
NK8235 is backward compatible with NK8223 and NK8225.
The NK8232 allows connection of a single safety or security subsystem to DMS8000
Management Stations, and is best suited for distributed systems or geographical net-
works where only one subsystem needs to be connected to a remote management
system (such as a bank application: centralisation of security systems of branches).
The NK8235 allows connection of multiple IC BT and 3
DMS8000 Management Stations, and is best suited for local systems, campus-size or
wide area extension systems, where more than one subsystem has to be connected,
or system extensions with additional subsystems are expected.
The NK8232/NK8235 offers, in addition to the standard connectivity capabilities,
BACnet connectivity between NK823xs for network-wide interactions and to DMS8000
hosts.
The NK8237 is used as a gateway between Sinteso(or Cerberus PRO)/STT20 fire de-
tection systems and Modbus head-end/automation systems on LAN or over a serial
line. It provides for bi-directional Modbus RTU and TCP/IP connectivity to Sinteso or
Cerberus PRO and STT20 fire detection systems.
· TCP/IP on Ethernet connectivity for connection to local and remote management
stations. Transport protocol CMSDL/IP, BACnet/IP, or CEI 79-5/IP featuring 64-bit
encryption (FEAL algorithm) for high security banking applications, and support of
switched lines.
· Simultaneous multiple host connectivity (up to four) using CMSDL/IP protocol
(without encryption).
· Upstream serial connectivity to a local management station (MM8000/MK8000) us-
ing an RS232 line via CMSDL serial protocol.
· The upstream devices (MM8000 or MK8000) must be equipped with the
NS8011/NS8210 Network Driver for TCP/IP on Ethernet connectivity or with the
NS8012 CDI-Net Driver for serial connectivity.
