Some DMX slave devices have built-in terminators that can be manually activated with a mechanical switch or by software, or by automatically sensing the absence of a connected cable. A DMX512 network is called a "DMX universe". [4] Each OUT connector on a DMX512 controller can control a single universe.
Remote Device Management (RDM) is an addition to the DMX512 control protocol for stage lighting equipment, introduced in 2006. DMX512 was developed in the late 1980s as a standard protocol for lighting consoles to communicate with dimmers, but has since been used for more complex applications, including the control of intelligent lighting fixtures.
These lighting console solutions use software with a feature set similar to that found in a hardware-based console. As dimmers, automated fixtures and other standard lighting devices do not generally have current standard computer interfaces, options such as DMX-512 ports and fader/submaster panels connected via USB are commonplace.
The major advantage of a lighting control system over stand-alone lighting controls or conventional manual switching is the ability to control individual lights or groups of lights from a single user interface device.
A common dual dimmer module used in stage lighting A dimmer. A dimmer is a device connected to a light fixture and used to lower the brightness of the light.By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output.
Digital Addressable Lighting Interface (DALI) is a trademark for network-based products that control lighting.The underlying technology was established by a consortium of lighting equipment manufacturers as a successor for 1-10 V/ 0–10 V lighting control systems, and as an open standard alternative to several proprietary protocols.
AMX192 (often referred to simply as AMX) is an analog lighting communications protocol used to control stage lighting.It was developed by Strand Century in the late 1970s. Originally, AMX192 was only capable of controlling 192 discrete channels of lightin
DMX, Inc., formerly Audio Environments, Inc., and later AEI Music Network, Inc., [1]: 19 was a "multi-sensory" branding agency based in Austin, Texas. [2] [3] DMX also provided music for cable and satellite television networks worldwide, including DSTV in Africa. It was the first company to offer music by satellite.
