ID Addressing
ID Addressing is a sub-addressing method by which each fixture, apart from its starting
address, can also have an “ID” address in the 1~66 range. This allows users to multiply
the number of fixtures they can control with a single DMX controller.
Many fixtures have at least one DMX personality or mode that enables ID addressing.
In this case, one of the channels of such DMX mode is in charge of selecting an ID
address. When using ID addressing, setting the value of the ID addressing channel to
“0” allows for the simultaneous control of all the fixtures with the same starting address,
regardless of their particular ID address.
ID addressing is also a tool for creating special lighting effects by having several
fixtures sharing the same starting DMX address and ID address, as indicated below.
Single Row
Connection
The figure below shows a simple DMX layout that uses four fixtures, all with the same
DMX address and a unique ID address for each fixture. This allows the user to control
simultaneously the whole group of units at that DMX address by setting the ID
Addressing channel to
0
. Similarly, the user can control each fixture at that DMX
address independently by first selecting the DMX address and then using the ID
Addressing channel to locate the target ID address.

Standard Block
Connection
In the Standard Block connection, the fixtures appear in repeated rows of the same
length to form a block. For instance, three rows of fixtures with three fixtures per row
to form a 3 x 3 block. Each of the fixtures has unique, sequential ascending ID
addresses for the controller to control each fixture individually.
Repeated Row
Block Connection
In this type of connection, the fixtures appear in repeated rows or columns of the same
length to form a block. For instance, there may be three columns of fixtures with three
fixtures per column to form a 3 x 3 block. In this case, the fixtures form groups, each
with its own sequential ascending ID addresses. This way, the controller will control
each group of fixtures individually.

Repeated Block Connection
Other Effects
For other types of effects, you may group the fixtures in diagonal lines or place them in
random positions within a single block.
