OCTO MK3
eDMX to SPI pixel controller with Standalone Mode & Overdrive feature capable of transmitting up to 32 universes of SPI data in a compact 4-module DIN-rail form factor.
Unleash unprecedented power with 32 universe capacity and flexible port configuration
The OCTO MK3 is a powerful quad-output eDMX to LED pixel converter with overdrive mode, transmitting up to 32 universes. Robust and reliable, it connects directly to LED lights, elevating architectural, commercial, and entertainment projects. Designed for fast deployment, it supports Art-Net, sACN, ESP, and KiNet protocols, and works with over 20 industry-standard SPI LED strips.
It features flexible output configuration with up to 8 universes per port—2 outputs with Clock support or up to 4 outputs when repurposing Clock as additional data ports. The intuitive localhost web interface enables easy gradient effects via the inbuilt FX engine, with standalone shows on power-up—no DMX needed.
With installer-friendly features like Port Sync for synchronized output, network daisy-chaining, custom protocol creation, and flexible mounting options, the OCTO MK3 delivers professional LED pixel control for demanding installations.
The OCTO MK3 delivers double the capacity with 32 universes (vs 16U in MK2) and introduces NEW Port Sync technology for perfectly synchronized multi-port output. It offers flexible configuration with up to 4 data outputs via split port mode (vs 2 fixed in MK2), enhanced standalone FX with real-time preview—all in the same compact, DIN-rail form factor.

The OCTO MK3 delivers up to 32 universes of output—double the capacity of its predecessor. Supporting up to 5,440 RGB or 4,096 RGBW pixels, it’s the ideal solution for large-scale installations demanding maximum data throughput and performance.
Configure your outputs exactly how you need them. Each port supports up to 6U + 2U in overdrive mode, and when you don’t need Clock-compatible fixtures, simply enable “split port” to convert Clock outputs to additional Data ports—expanding your data output capacity. Mix and match configurations across individual ports to perfectly match your project requirements.
When using multiple ports with different protocols or DMX universes, timing mismatches can create visual inconsistencies. The OCTO MK3’s Port Sync feature ensures all ports stay synchronised, preventing inconsistencies and ensuring smooth operation across your entire installation.
Create stunning gradient effects without any external DMX source. The OCTO MK3’s inbuilt FX engine allows users to create gradient effects with real-time previews directly through the web interface. Configure the device to run standalone upon power-up—perfect for permanent installations or testing outputs on-site without requiring a dedicated DMX source.
With an industry-leading 5-60V DC input range, the OCTO MK3 can be powered directly from your LED pixel strips or dots via either port. This eliminates the need for additional power supplies and cabling, streamlining installations and reducing installation time and costs.
Every aspect has been engineered for ease of installation. The Identify/Reset button enables quick wiring verification without a network connection—when pressed, all 8 output universes are set to output the highest value (255) for 10 seconds. Dual RJ45 Ethernet connectors support efficient daisy-chaining (chains of up to 8 devices give optimum synchronisation between outputs). Choose between surface mounting or TS35 DIN rail installation with included accessories.
The user-friendly web interface provides intuitive device configuration, firmware updates, real-time universe buffer inspection, and comprehensive network statistics—making troubleshooting effortless.
The OCTO MK3 supports over 20 industry-standard pixel protocols including APA-102, WS2812B, SK6812, TM1814, and many more. Can’t find your pixel protocol in the pre-listed library? The OCTO MK3 enables custom pixel protocol creation for specialised applications (refer to the Custom Protocol Creation Guide for eligibility requirements).
