DMX Address Menu
The DMX start address is the most important parameter
to be defined when setting up your lights. By default the
fitting will be set to 00 .
The addressing will depend on the current selected
personality. For example if the light is set to RGBAW
mode (5 channels), the DMX address range will be 00 –
508.
Personality Menu
The ALEPH2 ET Mk2 has six different personalities or
operational modes, which can either be selected remotely
from any standard RDM controller tool or locally using
the control panel. The light behaves differently in each
mode, since the DMX channel distribution changes
according to the desired working personality. Set the
desired personality before patching your lights in any
lighting desk or control system.
– 8BIT RGBAW MODE (5 Channel)
This basic mode will turn the ET into a 5 channel light,
allowing to drive each available colour as an independent
dimmer. Each DMX channel uses 8 bits resolution where
000 is OFF, 255 is Full intensity, as described in the
following chart.
2 – 8BIT RGBW MODE (4 Channel)
As some lighting control systems do not support RGBAW
lights, we have implemented a RGBW mode so the fitting
can be used with any controller. Each DMX channel uses 8
bits resolution where 000 is OFF, 255 is Full intensity, as
described in the following chart.
3 – 8BIT (6CHANNEL) MODE
This basic mode will allow you to drive each colour using
8 bits resolution, setting the values from one of the 6
DMX channels where 000 is OFF, 255 is Full intensity, as
described in the following chart.
Example : to turn all the channels to full intensity, set all the
channels to 255 value:
Example 2: to turn only the red group colour to full intensity,
set the first channel to 255 value:
The smart dimming in this personality follows an “s” curve
resulting in a smooth LED output all along the 8 bits range.
4 - 6BIT ( 2 CHANNEL) MODE
This mode will allow you to drive each colour using 6 bits
resolution; setting the values from one of the 2 DMX
channels from 000 to 255 where the first channel of each
group will be (HIGH) and the following channel the (LOW)
one, as described in the following chart.
This personality gives the user full control on the output
dimming, so any colour combination can be generated.
5 - EXTENDED (9 CHANNEL) MODE
This extended mode offers a wide variety of output effects,
turning the ALEPH2 ET Mk2 into a very versatile unit, using 9
DMX channels, as described in the following chart.
COLOUR GROUP INTENSITY (CH1-CH5) operate as
described in the RGBAW personality plus they can be
modified or affected by the strobe function or master
dimmer channel, as described further in this section.

Although these 6 channels have no effect when the true
CCT mode is activated (9th channel > 0 0)
STRO E DURATION (CH6) this channel works in
conjunction with the strobe frequency from CH7. It will
only take any effect if the channel 7th > 0.
It defines the duration of the ON state and linearly
increases the time from 2.5 milliseconds when 000 to 650
milliseconds when 255.
NOTE: Strobe duration time must be lower than Strobe
frequency for flashing. If duration time is equal or greater
than frequency, the light will be continuously ON.
STRO E FREQUENCY (CH7) will turn the ALEPH2 ET Mk2
bar into a versatile multi-colour strobe with user
adjustable frequency. The strobe feature can be activated
by setting the channel to a value between 0 and 255. In
the same range, the strobe frequency can be adjusted by
varying the channel value, with 0 the lowest frequency
(about 0.3 flashes per second) and 255 the highest one
(25 flashes per second).
The strobe channel can be used in conjunction with all the
other channels, so you can change the current output
colour or the master intensity whilst strobing at the
selected frequency, all at the same time.
MASTER DIMMER (CH8) drives the general intensity,
multiplying with all other current output channels, with 000
the lowest intensity 0% (light will be OFF, regardless of other
channel values) and 255 the highest, allowing 00%
whatever other channels are demanding.
TRUE CCT MODE (CH9) will turn the ALEPH2 ET Mk2 bar
into a true colour temperature adjustable fitting, simulating a
tungsten light behaviour.
The white colour feature can be activated by setting the
channel to a value greater than 0 0. CH9=0 will produce
the warmest white and 255 the coolest one. Values between
000-0 0 will stop the true CCT feature.
The true CCT mode channel can be used in conjunction with
strobe and master dimmer features, so you can strobe
and/or dim the current white output set by this channel.
The ALEPH2 ET Mk2 has been laboratory calibrated to
closely follow the black body Locus curve. With 8 bits
resolution allowing the light to travel from TRUE warm to
cool whites ( 2000K to 800K) keeping a high CRI for natural
colours.
6 – 8BIT CHANNEL MODE
This mode turns the Aleph 2 ET Mk2 into a single colour,
single channel dimmer.
The output colour is not any specific kind of white and this
mode is not tuned up to produce balanced output. It is only

meant to produce as much light as possible using only
one control channel.
This mode is often used to control custom built A2 lights
where only white LEDs are populated instead of coloured
LEDs.
Presets Menu
The Aleph2 ET Mk2 has 64 available slots where the user
can record custom colours from DMX. These can later be
activated from the menu. Presets turn the ET into a stand-
alone fitting, where 64 different colours can easily be
triggered on-site, without the need of DMX.
It is also possible to record user personalised presets on
any of the 64 memory slots, overwriting the default ones.
RECORDING CUSTOM PRESETS:
To record your own colours, please scroll to the desired
slot (from 0 to 64), feed the desired data through the
DMX port until you are happy with the look. Then press
the SET key to overwrite the preset.
IMPORTANT NOTES:
When the light is powered on, it will automatically take
preset 0 as the default power on value, if the Lamp On
Mode setting is ON. This feature is handy for the user to set
up the desired colour combination for the fitting to start
every time it is powered up.
Note that the strobe feature is not a supported preset.
Any incoming DMX data will override the presets, so ensure
that there is no DMX data coming in before navigating this
menu intending to playback the different colours.
Running the Factory Defaults RDM command will restore all
the presets to the original values and user recorded presets
will not be recoverable.
Lamp On Mode Menu
This setting instructs the ET about what to do after a power
up sequence.
If DMX or OFF settings are chosen, the ET will stay off and
will wait for DMX instructions.
When Lamp On Mode = ON the ET will power up and then
output whatever drop has been recorded in slot 0 of the
presets. Please notice that any incoming DMX will override
this preset, as DMX takes the highest precedence.
PWM Frequency Menu
The PWM driving frequency can be adjusted. This might
have an impact on the way some cameras respond to the
light emitted by the A2 ET Mk2.
Backlight Menu
The NORMAL setting will turn the display green back light
on after any key operation. It will turn it off after a 5
seconds of in-activity. The ON setting will keep the back light
always on. The OFF setting will keep the back light always
off, regardless of any operation.
Factory Defaults Menu
Running the Factory default sequence will reset all the user
configurable parameters, including DMX address, presets,
Personality, Lamp On mode, Etc.
