4.8 BINDING COMMUNICATION BOARDS TO NETWORKS

This section describes how to carry out the configuration procedure necessary to bind a LonWorks

Communications Board to the digital network. As the board forms part of the Transmitter Unit the

component becomes a node on the network.

The procedure is necessary after fitting a LonWorks Communications Board to an Apex Transmitter

Unit and connecting the digital network wiring (also see

Chapter 3

(1)

Power-up the Transmitter Unit.

(2)
