EUROLIGHT LC2412

9.1 Cables recommended for DMX512

The cables should be manufactured according to EIA-485 or EIA-422 specifications. Using shielded, twisted, double-stranded data transmission cables is recommended. For example, these are the same cables used for transmitting digital audio data in the AES/EBU format. You can also implement lines with a second wire set, used as a replacement in case of a malfunction.

Using high-quality mic cables is also possible, but their length shold be limited to 500 m due to the high cable capacity near a data line.

9.2 Terminal resistor (bus termination)

Using a termnal resistor at the end of the line is an additional condition needed for glitch-free data transmission. To this end, a 120-Ohm resistor is located between both conductors (Pin 2 and Pin 3) in an extra connector. Connect this connector to the DMX out connector of the last piece of equipment in the DMX chain. Shorter connections (up to several meters/roughly 15 ft) do require termination.

9.3.1DMX512 connections

The DMX512 norm mandates the use of 5-prong XLR connectors. The correct layout is shown in fig. 9.1.

9.3.3 MIDI connection

Coonect to other MIDI equipment or another EUROLIGHT LC2412 by using common MIDI cables. The cables should never be longer than 15 m (45 ft).

9.3.4 Audio connections

To control the EUROLIGHT LC2412 via an audio signal, please use a mono jack connector with standard configuration.

9.3.5 Footswitch

You can use a footswitch to trigger chase steps. This way, both of your hands remain free, letting you control additional settings of your LC2412.

Fig. 9.3: Footswitch connector

As long as a footswitch is kept pressed, the connection of both contacts is closed. Therefore, a footswitch does not act as a switch.

9.4 Rack mounting

Your EUROLIGHT LC2412 is factory-equipped with rack- mounting brackets. You can screw these on to the side of your LC2412 on a per-need basis.

+Always make sure that your LC2412 is provided with sufficient ventilation to avoid overheating of the unit!
