During the past two decades, following the trend of increased use of LEDs in entertainment lighting, there has been a shift to visual design that incorporates pixel mapping, which is a method of creating arrays of individual light sources that can be programmed to create dynamic visual surfaces, shapes, patterns and images.
Because pixel-mapped lighting tends to require a large quantity of DMX addresses, new communication protocols have been developed to support its deployment. ArtNet is an industry-standard lighting control protocol that makes it possible to configure and manage multiple DMX universes using standard ethernet LAN and WLAN networking conventions, cable and hardware (routers, switches, bridges, hubs, etc.) by integrating DMX frames into Art-Net frames. ArtNet distributes DMX and RDM data through an ethernet network using UDP-based packets. In such networks, ArtNet nodes (ArtNet-to-DMX converters) are used to send DMX values to lighting

Chromateq software and hardware solutions are designed to facilitate the process of designing and programming ArtNet-based lighting systems. Becoming familiar with the terminology used when describing ArtNet systems will be helpful to understanding the functionality and features of Chromateq control solutions, which are based on industry-standard rules for ArtNet implementation.
