What is Art-Net?

Art-Net is actually a data communication protocol, a method of signal transmitting (DMX512 and RDM) over an ethernet network. Generally speaking, it is made use of communicating between smart DMX/RDM controllable lighting and computer operating lighting control software. DMX was developed to control as much as 512 channels, and Art-Net is a simple application of DMX512 protocol over User Datagram Protocol (UDP) through which relevant lighting control info is conveyed in IP packages. It is widely used to transmit and receive lighting data, to detect and upgrade lighting fixture.

Versions of Art-Net

During the course of the past 2 decades, DMX lighting fixtures increased by leaps and bounds, the market was in great need of a lot more channels, the limit of DMX universes became problematic. Art-Net has undergone 4 versions to address the issues.


Art-Net I

The very first version of Art-Net was developed and released in 1998, it is now called Art-Net I. Art-Net I substantially used broadcast data for all communications, but it had a universe limit giving approximate 40 universes. However, with the trending DMX RGB lighting fixture emerged in the market, Art-Net I could not meet the demand of growing channel quantity, the broadcast topology was finally eliminated after years of the competition in the lighting industry.


Art-Net II

Art-Net II was developed to solve the problem of 40 limited universes, releasing in 2006 by using unicast packets with effective limit of 256 universes. Art-Net II decreased enormous network loading, enabling Art-Net II systems to level as much as transmission capacity of the network


Art-Net III

In 2011, Art-Net III was released to address problems in managing larger amounts of universes. The quantity of universe can be addressed from 8 bit to 15 bit, making it possible to address as many as 32,768 universes.

The lighting designer can develop gateway with more than 4 ports by using Art-Net III. Nevertheless, a unique IP address is a must for logical block of 4 ports, making it difficult to deal with large scale lighting jobs.


Art-Net IV

In 2016, a further updated version Art-Net IV was released, the up-to-date version solved the problem of multiple IP addresses by integrating a brand-new approach of managing gateways that support a number of DMX ports. This solution allows a gateway with only one IP address to support 1,000-plus DMX ports.

Besides, Art-Net IV make it possible for the technicians to use sACN along with Art-NET as well as RDM to deliver enhanced lighting control solution.
