2.2.1 DMX512

Data transmission in the field of lighting equipment refers to
transmitting control information from the lighting console via the
dimmer to the headlights, scanners and similar equipment. This
process takes place by using the digital DMX512 control signal
that was developed at the USITT (United States Institute for
Theatre Technology). Information is no longer represented through
analog voltage values; instead, digital data sets are used. In
contrast to analog data transmission, digital signals can simply
be “patched” together: each “piece” of information has an address
to which it belongs. Additionally, the following goes for digital
signals: when they arrive at their destination, they have the
correct value since there is no loss of quality associated with
analog signals.
Of course, problems may arise here as well. Very often, the
reason for faulty transmissions lies in deploying wrong
connectors or connectors other than those prescribed by the
norm. Using wrong cables also may lead to faulty data
transmission. We therefore only recommend using cables that
are intended for use with digital audio technology.
The DMX standard contains 512 digital light channels that are
controlled using a common data cable. However, a maximum of
32 different pieces of equipment can be connected to any one
cable since the cable at some point becomes overburdened
(due to shared controlling of all end equipment). Still, each piece
of equipment can evaluate as much data as you wish. To connect
additional pieces of equipment, you need a so-called splitter or a
booster to amplify or to regenerate the DMX signal.
DMX512 is a compatible norm and requires only one data cable
since all signal recipients are freely addressable, so you avoid
having “cable salad” issues. Once all pieces of equipment are
correctly connected and addressed, a DMX system typically
works completely trouble-free.

2.3 ANALOG mode

In addition to the digital DMX mode, your EUROLIGHT LD6230
dimmer pack also lets you work in ANALOG mode. You get to
this mode by pressing the MODE key while the CONFIG key is
pressed (the ANALOG LED lights up). The analog control signal
(0 - 10 V) is transfered to the dimmer pack via an 8-pole DIN
connector located on the rear panel. This way, you can use the
LD6230 with analog control equipment.
In ANALOG mode, each dimmer channel has a control cable
(or a core pair) of its own. The control signal runs through this
cable. The output voltage of the dimmer is proportionate to the
control cable signal. As a rule, 0% is represented by a voltage of
0 V, 50% is represented by a voltage of 5 V and 100% is
represented by a voltage of 10 V.

2.4 MANUAL mode

To power up your lighting equipment, the EUROLIGHT dimmer
pack can be used even without an external lighting console
when in MANUAL mode (MANUAL LED lights up). In this mode,
all settings are automatically saved every two seconds and can
be recalled even after powering the LD6230 off and then on
again. As with other operating modes, you get to MANUAL mode
by pressing the CHANNEL key while the CONFIG key is kept
pressed.
The left display digit indicates the channel selected with the
CHANNEL key. The next two digits to its right indicate the level of
the control signal, with values from 0 to 99. Use the UP and
DOWN keys to adjust the control signal value.

Lighting equipment is an integral part of almost every
performance event and venue. Be it concerts, theatre or musical
acts, clubs or even presentations and exhibits, they all benefit
from good visuals in order to leave a lasting impression on the
audience.
In general, lighting either creates a certain feeling or emphasizes
the mood created through music or dramaturgic composition.
Creating a lighting setup is a demanding and creative endeavour,
since it is much more than merely making a set of lights go on and
off. To do this, you need a dependable, multi-functional set of
tools. The EUROLIGHT LD6230 offers a maximum on functionality
and is the perfect expansion for a lighting console, preferably
the BEHRINGER EUROLIGHT LC2412.
Thanks to digital DMX controlling, using multiple dimmer packs
lets you implement demanding lighting setups, since you can
control up to 32 components with only one DMX connection.
These components don’t necessarily have to be headlights; in
switch mode, you can also control fog machines, pyrotechnic
equipment or motors. This makes the LD6230 much more than
just a piece of lighting equipment.
The following illustration shows a connection example with
two EUROLIGHT LD6230s, a BEHRINGER EUROLIGHT LC2412
and BEHRINGER ULTRAPAR UP1000 headlights, whereby 12
light channels can be run. The first dimmer pack is controlled
with the digital DMX control signal, the second one with an analog
signal. If both dimmer packs are controlled with the DMX control
signal, the second dimmer pack needs to receive the control
signal via the first dimmer pack:

and the ULTRAPAR UP1000 headlights
If you need more light channels, connect extra dimmer packs
for processing your control signals.
