light to the Dimmer. The Dimmer will control the light directly and will receive its commands from another device on the C-Bus network (for example, a wall-mounted light switch/keypad). This wall-mounted light switch would not be connected to any load whatsoever; it would be directly connected with the Dimmer with a control/signaling cable. The
Dimmers normally come as 4-, 8- or 12-channel DIN-rail mounted devices.

The wired C-Bus system uses a standard category 5 UTP (Unshielded
Twisted Pair) cable as its network communications cable and does not require end-of-line termination. Clipsal manufactures a specific category 5 cable for use within electrical distribution panels. This cable has a pink outer sheath
225:
The category 5 C-Bus network wiring uses a free topology architecture. The maximum length of cable used on a C-Bus network is 1000 metres; however, this is easily extended using C-Bus
Network Bridges. Up to 100 units can be installed on a C-Bus network and this can also be extended using Network
276:
The power control in a C-Bus system lies in a “Dimmer” or “Relay” which is installed in the DB and replaces the traditional switch used in conventional wiring. This Dimmer (or Relay) has a 120/230 V Line interconnection directly to the ceiling light and a neutral connection back from the ceiling
229:
The maximum number of C-Bus networks in one installation is 255 (note that this limitation does not apply if a C-Bus
Ethernet Interface is used, the system size is then limited to IP Addressing only). The maximum number of networks connected in series to the local network via Network Bridges is
246:
The isolation between the main supply circuitry and the 36 V DC C-Bus circuitry is greater than 3.5 kV. This is achieved using double wound transformers and opto isolators. This means the C-Bus wiring, connections and circuitry can be considered Extra Low
Voltage.
265:
In C-Bus systems, the connections between the DB and (for example) the ceiling lights, and between the DB and the junction box (wall switch) are completely separate. In addition, there are no connections between the junction box and the respective ceiling lights.
202:, C-Bus uses a dedicated low-voltage cable or two-way wireless network to carry command and control signals. This improves the reliability of command transmission and makes C-Bus far more suitable for large, commercial applications than X10.
239:
Each C-Bus network requires a network burden if there are insufficient C-Bus units on the network. This network burden can be enabled on C-Bus output units through software or a hardware burden can be connected to the network.

which is rated to ensure adequate electrical isolation between the mains voltages found in distribution panels and the extra low voltage C-Bus. Outside of distribution panels standard category 5 UTP cable can be used.

Using one of
Clipsal's C-Bus interface modules (PCI for RS232 or USB and CNI for Ethernet TCP/IP), you can interact with other home automation systems, or with applications on devices like Android, iPad or iPhone.

The C-Bus protocol was developed using the OSI 7-layer reference model. C-Bus supports several interfaces such as RS232 and TCP/IP and makes these protocols available to third-party companies.
327:), Russia and a number of other countries are now using this system. The C-Bus wireless (RF) system and wired C-Bus Occupancy Controllers can be retrofitted using the existing mains wiring.

More than one C-Bus power supply can be connected to a C-Bus network to provide sufficient power to the C-Bus units, the C-Bus power supplies will share the load evenly.

With conventional wiring, the mains power (120 / 230 V) is wired from the distribution board (DB) to the load (for example, a ceiling light) via a wall switch.
