Programming Principles
All C-Bus
TM
devices require programming, with
the exception of power supplies. Programming is
achieved with proprietary software using a PC. Unit
programming is performed to achieve the following
objectives:
• Create and dene units on the C-Bus network
• Identify each unit using the C-Bus addressing
convention
• Create, dene and edit control relationships
between inputs and outputs
• Edit unit operating parameters
The operating parameters vary from unit to unit,
depending on its type.

Addressing Conventions
Once a preliminary list of hardware requirements has been
created, planning of the programming requirements may begin.
The C-Bus network uses a simple addressing scheme to
identify units, groups, areas and networks. The purpose of each
parameter will be discussed in the next section.
Alphanumeric Characters
Legal Alphanumeric Character Set: 0-9, a-z, A-Z, ‘ ‘, ‘_’
All descriptive addresses accept the above legal
characters. Other characters may be accepted, but are not
recommended.
Project Names and Part Names will force capital letters.
Hexadecimal Symbols
Hexadecimal Symbol Set: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F
At a physical level, the programming information downloaded to C-BusTM Units consists of a two digit hexadecimal number,
represented be a combination of the above 16 symbols. Valid addresses include 12, AB, FE, 5E. The descriptive addressing is not downloaded.
This information is stored in a database on your PC. A programmed C-Bus network can be scanned using the C-Bus Installation Software. If
a Version 7.1 Project Database has not been dened by the user, the software will use the hexadecimal addressing uploaded to represent all
unknown addressing. Users should note that these hexadecimal addresses are automatically assigned. The Project and Topology Managers
may be used to reference or manipulate hexadecimal address as required.
Group Addressing
The Group Address is usually related to the load physically connected to the terminal of the output unit. Therefore, the group address
should accurately describe the load being controlled. Typically, numerical designators are used to describe lighting circuits. Up to 255
group addresses may be dened on a single network less any dened area addresses.Valid groups include: Ofce Lights, Hall Lights,
L4-2B, A4-2L-3 The default group is “unused.”
