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.

◊ 

When the dimmer pack receives a zero signal level at the input end, 
the output signal level should correspondingly be at its minimum. 
When the dimmer pack receives a maximum signal level at the input 
end, the output signal level should be at its maximum.   

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.

3.  Applications

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:

If you need more light channels, connect extra dimmer packs for processing your 

control signals.
