The C-Bus Network

The C-Bus Network Bus is the communications wiring for the system,

consisting of an unshielded twisted pair (UTP) ‘Cat 5’ cable. The

Network Bus also provides the small amount of power needed to

operate the circuitry within C-Bus units. The C-Bus Network operates

at safe extra low voltage levels (36V dc).

Free Topology Structure

C-Bus devices are wired to any point on the Network by a twisted

pair cable. The C-Bus connections may be looped from unit to unit,

or a branch can be made at any point. This ‘free topology’ structure

provides a flexible system layout. New units can be added anywhere,

at any time, without system re-configuration.

Unlimited Capabilities

A large installation is usually divided into Networks of 100 C-Bus

Units, with a total cable length of 1000m per Network. This allows a

C-Bus system to be divided into manageable sections, simplifying

design, limiting potential fault propagation and aiding in any trouble-

shooting.

Peer-To-Peer Communication

Every C-Bus Unit is assigned a unique name, so that all the devices

on the C-Bus Network can communicate directly. Every device on

the C-Bus Network issues and responds to commands directly from

the Network, rather than requiring a central computer or controller.

Clipsal C-Bus was the first Australian designed and manufactured building and home

management system released on the Australian market in 1994. Since that time it has

reached unprecedented success in both the Australian and international market. C-Bus

has provided energy savings and unsurpassed control flexibility in commercial buildings

and residences.

Whether providing simple ON/OFF control of a lighting circuit, or variable control such

as dimming electronic fluorescent ballasts, C-Bus is used to easily control virtually any

type of electrical load.
