Will a Network Management

Tool Be Used?

If NO, and the NCB will be used
with its factory default settings
(Repeater Mode), skip the rest of
this section. The NCB is ready to
function in a network.

If NO, and the DOS NCBCON
program will be used to access
and configure the Control Neuron
Processor, then see Technical
Note TN023.

If YES, and LonMaker For
Windows will be used, be certain
that ‘OPTION A Switch 5 is in
the DOWN position,
and see
Commissioning the NCB with
LonMaker for Windows
later in
this section.

If YES, and another Network

Management Tool will be used, be
certain that ‘OPTION A Switch 5
is in the DOWN position,
then see
Technical Note TN026.

Commissioning the NCB with LonMaker for Windows

Commissioning each NCB in a network with LonMaker for Windows involves commissioning two different
network devices, both contained in the single NCB enclosure: a standard LonWorks router, and the control
neuron
.

Since the standard LonWorks router portion of an NCB router interfaces a LonWorks channel to a Telephone
(WAN) channel, it requires connection to two channels on the LonMaker drawing. A standard LonWorks
channel will be connected to Side B of the router shape, and a CUSTOM (Telephone, WAN) Channel will be
connected to Side A of the router shape.

Commissioning the NCB control neuron requires that the .XIF file be available. The simplest way to do this is
to install the NCB/Plug plugin, as this process copies the required .XIF file to the proper directory.

Why is a Network Management Tool
needed?

Factory Default Settings

An NCB could be placed in a network using the
configuration as it was shipped from the factory
(Repeater Mode, fixed Subnet/Node address). All
messages would simply be passed through the NCB.
This may suffice for small networks where channel
bandwidth and message timing issues are of no
concern.

Use of a Network Management Tool

If a larger network is planned, and channel bandwidth
limitations require segmentation of message traffic,
then a Network Management Tool should be used to
perform some or all of the following functions:

Assign unique addresses to each NCB Router

and Control Neuron

Configure domain address tables in routers

Optimally set Transaction Timers based on

Channel Delays

Configure forwarding tables in routers for traffic

segmentation
