C-Bus Wireless System Operation
C-Bus Wireless Networks
To experience the full capabilities of wireless operation, C-Bus Wireless units must be
linked together to form a network.
To communicate with each other, units within the same network should be located
within 15 to 20 meters of each other. This distance depends on building materials used.
Up to 30 units may be connected within the same C-Bus Wireless network.
Basic Operation
Buttons on a Wireless Wall Plate or Plug Adaptor are organised in pairs that control the
output channels (local control buttons). Remaining pairs (free buttons) are used to
control outputs on other units when multiple C-Bus Wireless units are congured as
part of a network. For example, the gure below shows a 6 button, 2 channel ULTI
Wireless Dimmer unit. Its buttons perform the following functions:
• Buttons 1 and 2 control the rst channel. (A quick press on either button toggles
the channel on or o. A long press on button 1 or 2 dims down or up respectively).
• Buttons 3 and 4 control the second channel.
• Buttons 5 and 6 are unused when the unit is used as a stand-alone unit. They may
be used to control outputs on other units when part of a multi-unit network.
When a C-Bus Wireless Wall Plate or Plug Adaptor unit is rst installed, it functions as
a stand-alone unit. In this basic default mode, the unit functions as a dimmer or switch,
depending on the model.
C-Bus Wireless Plug Adaptors have one output channel (a single, 240VAC socket) and
two buttons. Wall plate units are available in one or two output channel versions, with
two, four, six or eight buttons (eight button, NEO only). Each channel controls one or
more lights or other electrical devices connected to its output.
C-Bus Wireless Network Security
C-Bus Wireless units can optionally use 128-bit encrypted messages to communicate
with each other. This results in a highly secure network.
Nearby C-Bus Wireless Networks
It is possible to have several separate networks present alongside each other without
interfering, as each separate C-Bus Wireless network has an automatically assigned,
unique ‘House Code’.

C-Bus Wireless Modes of Operation
C-Bus Wireless units have ve major modes of operation.
Mode 1
Stand-Alone Mode
In this mode, C-Bus Wireless Wall Plates and Plug Adaptors acts as stand-alone dimmers
or switches and make no use of the inbuilt wireless capabilities. No setup is required
for this mode, Plug Adaptors simply plug into the mains, and Wireless Wall Plates are
installed by a licensed electrician in place of existing wall switches. The buttons on the
units control the local dimming or switching channels of the unit only.
Mode 2
Simple Remote Controlled Mode
In this mode, a C-Bus Wireless Wall Plate acts as a standalone dimmer or switch and
a C-Bus Wireless Remote Control operates the Wall Plate from a distance. This mode is
simple to set up and is suitable for small installations where networking is not needed.
C-Bus Wireless Wall Plate or Plug Adaptor units are controlled using a C-Bus Wireless
Remote: In this mode, the buttons on the Wireless Wall Plate control the local dimming
or switching channels of the unit, and the Remote Control is linked to buttons on a
Wall Plate using a Learn Mode operation. No PC is required.
