Q
This Quick Start Guide provides a concise series of steps to get a pair of the NCB-Etherlon or NCB-Fiberlon
modules “up and running” quickly so that initial operation may be confirmed.
It is highly recommended that a pair of NCB-Etherlon or NCB-Fiberlon modules be tested in your application
by first connecting them “back-to-back” with the 10BaseT or fiber crossover cable included with this shipment.
Once operation is confirmed using this connection scheme, continue by reconfiguring the IP addressing
information and connecting the NCB modules to the actual Ethernet communications channel to be used.
TART GUIDE
-S
NOTE: DO NOT connect the NCB-Etherlon or NCB-Fiberlon modules to a live IP network
until they have been reconfigured with new IP addresses and subnet mask supplied by the
network manager. Network-wide problems could arise from connecting devices to a network
without coordination of addressing information. See the Installation section of this manual

The Network Combiner NCBTM Module is a device that, when used in pairs,
allows multiple

networks to be connected in real-time, spanning
distances from building-wide to worldwide. The communication channel
spanning the distance between local networks can be any copper or fiber Ethernet
Read this

the general
function and

channel that is capable of carrying IP (Internet Protocol) data. Data transfer
between distant networks via NCB modules is "live", delayed only by the transit
time through the routers and Ethernet channel.
The NCB module uses router technology so that no custom coding or additional hardware is necessary to
seamlessly connect multiple networks across very large distances. The NCB module is self-contained, easily
configured with standard network management tools, and requires no custom programming or coding changes
in system nodes.
Both the NCB-Etherlon and the NCB-Fiberlon utilize the IP protocol over an Ethernet media and both can
coexist on a wide-area IP network with other IP devices such as workstations, servers, and IP routers.
Additionally, they can exist on
dedicated
Ethernet IP networks, where the only devices on the network are
NCBs and (optionally) physical layer hubs. The most common occurrence of a dedicated network is a set of
NCB-Fiberlons connected with dedicated fiber.
Basic Application
A basic application of the NCB module is where two multi-node
beyond the reach of conventional wired media, need to be interconnected, as in Figure 1. This distance could be
across a large building, business campus, city, etc. Using the NCB module, this interconnection is
accomplished using one NCB module local to each network site and an Ethernet channel connecting the NCB
modules. Additional networks can be added to this unified network by simply adding an NCB module for each
network.

There are three sources of message packets within the NCB module. The first source is the

unit. (Note that although 10BaseT and AUI connectors exist, only one can be used at a time.) The third source
is the Control Neuron Processor. Message packets originating from any of these sources are sent to the other
two. This message packet flow is shown in the block diagram of Figure 2.

Router Function
The router contained in each NCB module may be configured as a repeater, bridge, or configured router. The
easiest configuration is as a repeater, where all messages which enter the NCB module (via any of the three data
sources described above) are simply passed to the other two sources, regardless of the domain, subnet/node, or
group destination address. A bridge forwards only messages that match one of the two domain IDs configured
on the router. A configured router forwards only messages that match a domain ID as well as a set of subnet or
group numbers. The proper choice of router mode depends on desired simplicity of installation versus required
system performance.

This section describes the steps necessary to install NCB-Etherlon and NCB-Fiberlon modules into a
ONWORKS

system.
NOTE : DO NOT connect the NCB-Etherlon or NCB-Fiberlon modules to a live IP network
until they have been reconfigured with new IP addresses and subnet mask supplied by the
network manager. Network-wide problems could arise from connecting devices to a network
without coordination of addressing information. For usage with dedicated fiber segments, see
the note below.
Overall Installation Functions
Installation of an NCB-Etherlon or NCB-Fiberlon into an IP network that is shared by other IP devices (such as
workstations, servers, etc.) requires performing the following three overall functions (not necessarily in this
exact order) :
A. Configure the IP address parameters for each NCB
B. Physically install each NCB into the system
C. Commission each NCB using a
Installation of an NCB-Fiberlon into a system using
requires performing only functions B and C above, as the default factory programmed IP address parameters
can be used.
Configuration steps for function A above are performed by using the EtherPlug configuration software supplied
with the NCB units. EtherPlug is a Windows program that can use a serial COM port and/or the
network to configure the IP address parameters for each NCB. EtherPlug can be used as an LNS Plugin with
programs such as LonMaker for Windows, or in a standalone mode requiring only Windows and a serial COM
port. In preparation for function 1 above (not required for NCB-Fiberlons using dedicated fiber segments),
basic IP addressing concepts must be understood. Appendix F of this manual provides a good overview. After
determining which IP addressing mode will be used (Unicast/Replicated or Multicast), the following IP
information must be gathered
