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
