All 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 (connected to Side A of the internal router). This section details the
Functional Blocks (objects) and the network variables of each. The Modem
Controller Objects and Directory Objects will be functional only if a modem is attached to the “PORT”
connector.
The Modem Controller Object is typically used in conjunction with the Directory Object and some other event-
generating object which causes connection control information to be given to the Modem Controller Object.
This information initiates modem dialing so that, once a connection is established, transfer of data can be
accomplished via the modem.
Figure 6 is an example of typical network variable bindings.
