Ethernet DMX Controller rev. 4.0

Hardware

The hardware underwent a fairly large update for this new revision. Notable additions and improvements are:

• a second, fully-independent, XLR5 port for two separate universes of input or output
• support for full PoE operation, requiring no external USB-C power
• full galvanic isolation between PoE power, USB-C power, and DMX outputs
• external-facing button supporting different actions based on short press or long hold

Software & Firmware

The firmware and configuration software updates for this revision were mostly focused on the fundamental operation of the device: things like the users ability to configure custom network settings, or low-level architecture improvements. While the device already supports standard day-to-day artnet functionality (ArtDMX, ArtIPProg, ArtCommand packets, etc), a more complete implementation of the Art-Net spec will be implemented in a future revision.

A list of the main changes:

• rearchitected the firmware to support a variable number of DMX input and output ports
• refactored the ethernet and DMX processing pipeline for much safer and faster operation
• added device configuration through local webpage hosted at device IP, no external internet connection needed
