Lighting Scenes with Digital Multiplex (DMX)

The Digital Multiplex (DMX) protocol originated in the theatre and events industry to control intelligent lighting equipment and special effects devices. DMX is also increasingly being used in commercial buildings for applications including RGB, color and light temperature control.

In these buildings, light is frequently used as a design element, such as for effects and architecture lighting, facade lighting and to accent special architectural features. The protocol focuses on modern LED technology, which is used for special lighting effects because it is efficient and provides a dazzling array of colors.

DMX is based on the RS-485 serial interface standard. Typically, three-pole XLR plugs are used for cable connections.

DMX Master

• Writing DMX telegrams from the WAGO-I/O-SYSTEM to DMX devices (e.g., switching, dimming, LED light color control)

• DMX transmitter for 1 to 512 channels

DMX Slave

• Reading DMX telegrams for further processing in the WAGO-I/O-SYSTEM (e.g., switching hall illumination from DMX light control console)

• 21 DMX channels (process image size = 24)

• Selection of any address range from the entire DMX address range through an adjustable start channel (WAGO-I/O-CHECK as of Version 3.10.8)
