The DMX512 Signal Decoder is designed for LED fixtures, converting DMX512/1990 signals into various LED driver IC formats using advanced micro-computer control. It enables non-DMX-compatible LEDs to integrate with DMX systems and supports channel and pixel merging for efficient control using just one channel for monochrome and two for dual-color strips. Pixel merging allows each DMX port to drive more fixtures, making it a powerful solution for scalable, streamlined lighting installations.
