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.
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.
