    DMX-512 Stack

    Control stage lighting effects for your theatrical productions and concerts

  • softDMX
  • Overview

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

    It is widely used to control stage lighting and 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’s DMX-512 receive and transmit stack enables lighting end-points and transmit devices to achieve compliance with the DMX-512 standard. The stack operates with minimal memory footprint and supports custom configuration.

    Value-added services include porting of DMX-512 stack to device platforms, integration with device applications and complete product testing.
