DMX address and protocol
The DMX address, also known as the start channel, is the first channel used to receive instructions from the
controller. For independent control, each fixture must be assigned its own control channels. Two
smartMACs may share the same address, however, if identical behavior is desired. Address sharing can be
useful for diagnostic purposes and symmetric control, particularly when combined with the inverse pan and
tilt options.
Depending on the selected DMX mode, the smartMAC requires 12 or 15 DMX channels. 8-bit mode uses 12
channels and provides coarse control of all effects. 16-bit mode uses 15 channels and provides the 8-bit
mode features plus fine control of gobo rotation, pan and tilt.
DMX addressing is limited to channels 1-501 in 8-bit mode and 1-498 in 16-bit mode. This makes it
impossible to set the DMX address so high that you are left without enough control channels for the fixture.
To set DMX address and 8-bit or 16-bit mode
1. Press [Menu] to enter the main menu.
2. Press [Up] or [Down] until

is displayed. Press [Enter]. To snap to channel 1, press [Enter] and
[Up]. Scroll to the desired channel and press [Enter]. Press [Menu] to return to the first level of the main
menu.
3. Press [Up] or [Down] until

is displayed. Press [Enter]. Select

for 8-bit mode or

for
16-bit mode. Press [Enter]. 16-bit mode uses 3 additional DMX channels to provide fine control of
rotating gobo, pan and tilt.
Tailoring performance
Movement
The smartMAC provides several options for optimizing movement for different applications.
• The pan and tilt invert (

) menu swaps and/or inverts pan and tilt.
• The pan/tilt speed (

) menu provides 2 settings:

and

. The

(normal) setting
gives smoothest pan/tilt movement during slow scene changes and quietest operation. It is best for most
applications and is the default setting.

provides better performance in applications where speed is
most important.
• The effects speed (

) menu provides 3 settings:

,

and

.

If set to

(pan/tilt
speed slave), effects speed follow the pan/tilt speed set in the

menu. This is the default setting. As
with pan/tilt speed,

gives smoothness and silence.

gives extra speed.
• The pan/tilt and effects speed settings described above are overridden and set to ‘slow’ if silent mode is
selected in the

→

menu.
• The shortcuts (

→

) setting determines whether effects take the shortest path between two
positions, crossing the open position if necessary, or always avoid the open position.
Display
The display on/off setting (

→

) determines whether the display remains on constantly (

) or
goes into sleep mode 2 minutes after the last key press (

) or 10 minutes after the last key press
(

). The display can also be set so that it is activated if the fixture diagnoses an error.
The display intensity (

→

) setting controls display brightness. Select

for automatic
display or manually set the intensity to a level from

to

.
To invert the display when the fixture is installed base up, press [Up] and [Down] simultaneously.
DMX reset
The DMX reset (

→

) setting controls the behavior of the reset command. When set to

, the
command is fully enabled. When set to

, the command is disabled to prevent accidental resets. When
set to

, the command must be sent for five seconds. The special combination of DMX values listed
under channel 1 on page 37 allows you to execute a reset even when the command is disabled.
