DMX 512

DMX512 (Digital Multiplex) is a standard for digital communication networks that are commonly used to control stage lighting and effects, DMX512 employs EIA-485 differential signaling at its physical layer.

It is usually presented on 3 or 5 pin XLR although some LED drivers use RJ45.

Slight on Centos

Slight is a simple to use yet fairly powerful controller for straightforward stage lighting, it emulates a fader style desk. It does not support chases or automation other than scene changes with crossfades etc. This seems to have been un-maintained for many years. It used the dmx4linux driver to talk to the hardware.

Files needed to compile slight controller (slight-0.98d-sgt.tar.gz) for CentOS 5. dmx4linux-2.4-ftdi.patch.gz


yum install gcc-c++

yum install gcc-c++ compat-gcc-32 compat-gcc-32-c++

Work to do

Produce diff of changes slight needs to compile under above system.

Investigate if slight can talk to OLA rather than dmx4linux.
