DMX stands for DMX512

The USA Institute of Stage Lighting has proposed the DMX512 protocol. It is a data-dimming protocol that allows lighting controllers and fixtures to communicate.

DMX512 is a digital dimming protocol, it will be light level from 0 to 100% ,is divided into 256 levels. The control system can realize R, G, B 256 levels of gray scale.

DMX is used to control a series of lamps or lanterns that support the DMX512 protocol. Examples include computerized moving headlamps, LED Downlights and LED atmosphere lights.

DMX512 Key Features:

DMX512 stage lighting control can be transplanted to the touch screen or tablet PC, you can do scene presets, simplify the operation, etc.;

can directly control the use of the same agreement with any dimmer, composed of digital dimming control system;

can control all kinds of DMX512 protocols dimmers, silicon boxes, controllers, and even the cold flame machine, smoke machine, computer lights and other effects equipment;

can store the lighting scene, can be edited to go to the lights program, and at the same time to support dimming desk to run a manual dimming scene, set of control scenes, to go to the lights program.

DMX512 Wiring:

DMX512 eight-port inline controller. If you need online control (that is, computer control). First use the network cable to connect the controller and computer. Controller model is not the same that the connection is not the same.

Make a network of computers and controllers.

control the output. Output signal port, (signal output has a network cable port, terminal port, XLR head port) ,directly connected to the lamp signal signal with a signal line ,(signal line is divided into D + D- GND that is, the signal is positive, the signal is negative, shielded ground).

there are offline way, that is, not connected to the computer, the computer is changed to offline master control is ok.

DMX512 control divided into 2.

(1) internal control is no external controller, the designers designed the control system in the LED external control line light inside, the degree of effect can not be changed.

(2) external control is the external controller, the effect can be adjusted through the main control button and change the effect.
