In the fast-paced world of stage lighting, where reliability can make or break a performance, True DMX ports are a critical feature on devices like DMX splitters, nodes, and controllers. These ports, often labeled distinctly on professional equipment, ensure robust signal distribution in complex lighting networks. This article explores what True DMX ports are, how they function, and why they are essential for building resilient DMX networks in theater, concerts, and live events.

In live theater, lighting does more than illuminate—it sets the mood, directs audience focus, and enhances the narrative. A reliable lighting control system is critical, and this setup, powered by Sundrax’s GigaJet20 Pro, delivers exceptional reliability, flexibility, and safety for professional productions. Designed for lighting designers, stage managers, and technicians, it ensures seamless performance in high-pressure environments.

All control signals are integrated into the GigaJet Pro, which employs merging technology with automatic priority management and data backup functions.
DMX and RDM data are transmitted over optical fiber to a second GigaJet Pro, and then to a third GigaJet Pro, enabling the connection of all equipment and the transmission of multiple DMX universes over long distances.

Lighting control in architectural and entertainment environments often involves two dominant but very different protocols: DMX512 and DALI. While DMX is preferred for dynamic, fast-changing effects, DALI excels in commercial and architectural settings where smooth dimming, status feedback, and group control are essential.

As modern lighting moves toward immersive visual design, addressable LED pixels have become essential for media façades, creative stage effects, and interactive installations. At the center of these systems is the ArtNet pixel controller – a device that receives network-based control data and distributes it precisely across thousands of individual LEDs.

When it comes to critical facilities—such as theaters, public buildings, tunnels, or architectural facades—a failure in the lighting control system can lead to serious consequences. We spoke with an engineer from Sundrax Alex Chomsky about how to properly implement emergency lighting scenarios based on DMX and what to consider for reliable operation in emergency situations.

As the number of fixtures in DMX networks increases, the load on the line grows, raising the risk of failures and signal loss. Incorrect distribution can lead to erratic operation or complete equipment failure. We consulted with an engineer from Sundrax Alex Chomsky to learn how to properly design a DMX network for large-scale projects.

Learn why incandescent and halogen lamps change color temperature when dimmed and how to maintain stable lighting using high-frequency stage dimmers.

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.
