The ETC Net3 4-Port Gateway is a DMX and RDM data distribution device designed to integrate seamlessly into Ethernet-based lighting networks using industry-standard protocols such as sACN and ACN. It supports up to four configurable ports—DMX input, DMX output, RJ45, or terminal strip—in any combination, allowing flexible deployment across a variety of applications, including theaters, convention halls, touring rigs, and control booths. The gateway can transport up to 2,048 channels of DMX over Ethernet and features a modular design for easy port customization and replacement. An onboard LCD provides labeling, status, and configuration feedback, while LED indicators show power and network activity. The unit is powered via Power over Ethernet (PoE) or an external DC supply and can be configured using ETC’s Net3 Concert software or directly through ACN protocols.
