    DMX-512 (Digital Multiplex) is an open, serial RS-485 standard communication protocol is used for controlling lighting dimmers and fixtures. It is designed to provide seamless communication between lighting end-points, regardless of their manufacturer.

    It is widely used for controlling stage lighting and to create theatrical effects such as moving lights, color changing LED applications, fog machines, etc. DMX is also used in non-theatrical interior and architectural lighting.


    Softdel offers a ready-to-use, royalty-free DMX-512 receive and transmit stack. The stack enables lighting end-points and transmits devices to achieve compliance with the DMX-512 standard.

    We also offer services such as porting of DMX-512 stack to device platforms, integration with device applications, and complete product testing.
