ONTROLLING THE

WAN

ONNECTION

At this point, the “local” NCB (the one connected to the LonMaker for Windows NSI) has been configured and
fully commissioned for use. This last step involves making a connection to the “remote” NCB via the
Telephone (WAN) channel.

If a leased-line connection has been made to the remote NCB (via the actual leased-line to be used, or via a
back-to-back test phone cable) and the remote NCB has been configured properly, the “CD” LED on both units
should be on and message packets will flow between them across the Telephone circuit. To commission the
remote NCB router and control neuron, repeat B through E of Commisioning the Router in Step 4 above.

If a dial-up circuit is being used between the local and remote NCB’s, then the local NCB must be commanded
to dial into the remote NCB in order to commission it. The simplest way to command this dialing to occur is to
use the NCB/Plug plugin. Alternatively, the Network Variable interface can be used. See the following
tutorial. Once the dial-up connection is established with the remote NCB, message packets will flow between
them. To commision the remote NCB router and control neuron, repeat B through E of Commissioning the
Router in Step 4 above.

NCB/Plug

LNS plug-ins are applications that can be started
from within an LNS application (such as the
LonMaker tool) to perform a specialized task. The
NCB/Plug plug-In implements configuration and
query commands for the NCB. The NCB/Plug
plug-In and Network Variables can be used
simultaneously. The following functions are
available if the NCB/Plug plug-In is installed:



Send a dial string to a modem



Send a ‘Call Cancel’ command to a modem



Configure the NCB Telephone Directory



A window displays ‘Connect Status’



Select Dial Mode (Manual Dial or Perpetual

Connect)



Select Auto Answer Enabled Mode



Request a soft reboot of NCB

Network Variables

Network Variable Bindings allow a device to send
and receive messages to and from other devices
on the network. All configuration and status
commands sent to the NCB module are carried on
the LonTalk network in the form of Network
Variables bound to the Control Neuron Processor
inside the NCB module. The following functions
are available if Network Variable bindings are
made:
