DMX vs ArtNet vs sACN: Which Protocol to Choose for Your Installation?

In professional DMX installations, dozens or even hundreds of luminaires, controllers, splitters, and amplifiers are connected in a shared network through which the signal is transmitted. But what happens if a high-voltage surge ⚡️, for example, due to a short circuit, connection error, or even during a thunderstorm, enters one of the sections? Without galvanic isolation, such failures can damage or destroy all equipment across the network.

Digital control of architectural lighting is becoming an integral part of urban infrastructure. This article highlights the key technologies transforming the industry, according to Sundrax engineers. These are not mere predictions but specific directions already being implemented in modern projects.

Lighting today is far more than just lamps—it encompasses complex digital systems. To control lighting fixtures, various communication protocols are employed. Using Sundrax equipment as a reference, we will examine three popular options: DMX512, ArtNet, and sACN. Each protocol has distinct features, advantages, and limitations. Which is best suited for your project? Let’s explore with a Sundrax engineer.

Digital Multiplex, is a standard for digital communication networks that are commonly used to control stage lighting and effects. Frequently asked questions (FAQ)

For implementing large-scale lighting projects such as concert venues, theatrical productions, or architectural illumination, it often becomes necessary to deploy numerous lighting fixtures. The standard DMX512 protocol has limitations on the number of devices that can be connected to a single line. When connecting many devices to one line, the signal weakens, leading to distortions and data loss. To solve this problem, DMX splitters are used, allowing for more fixtures to be connected and complex lighting compositions to be created.

LED pixel controllers unlock boundless possibilities for creating unique light installations – from stage lighting to festive decorations. Light is a crucial part of artistic expression that complements reality, creates accents, and has every opportunity to transform any space into a work of art. LED pixel controllers allow lighting artists to achieve incredible precision and detail in creating light effects.
