DMX mode
The L7 offers, depending on the model, up to 15 DMX modes.
Use the 8 bit modes with basic DMX controllers like dimmer
consoles. The most common modes for operation via DMX are
mode 1 and mode 2.
ARRI recommends the use of the 16 bit modes in combination
with DMX controllers supporting 16 bit resolution to obtain best
results. The high resolution provides smooth dimming and pre-
cise color adjustments.
The coarse/fine modes utilize two DMX channels for most pa-
rameters and provide higher resolution compared to the 8 bit
modes in combination with DMX controllers that do not support
16 bit resolution. One channel sets the coarse value of the
function which is divided in 256 increments using the fine chan-
nel.
The setting can be changed any time using the rotary knobs of
the fixture menu.
White and RGBW
This mode provides control of intensity, color temperature, +/-
green and individual channels for controlling the red, green,
blue and white color.
White
Simple white-only mode. It is used when the number of avail-
able channels of the DMX controller is very limited. It provides
control of intensity, color temperature and +/- green.
White & HSI
Provides control of intensity, color temperature, +/- green, hue
and saturation (HSI = hue, saturation, intensity). In HSI mode
the color and intensity is very even over the fixtures as it is con-
trolled using color algorithms which take the tolerances of the
light engines into account during calculation.
RGBW
Simple mode for controlling the overall intensity and the red,
green, blue and white intensity when only a limited number of
DMX channels is available.
HSI
Simple mode for controlling hue, saturation and intensity when
only a limited number of DMX channels is available.
Please find a detailed description of all modes in chapter
“DMX Protocol” on page 34.
Note: Depending on the selected DMX mode the channels re-
quired for each product should be allocated in the DMX control-
ler to provide independent control of all products connected to
the controller. Please allocate the maximum number of chan-
nels, which is 14 in DMX mode 6.
