Meet the little box that packs a huge punch
The latest evolution of our 8-Universe, dual-output eDMX to LED pixel data converter, the OCTO Mk2 is a robust and reliable installation-grade device. This smart device connects directly to your pixels, engineered to take any architectural, commercial, or entertainment project to the next level.

Our DIN-rail LED pixel controller is designed for ultra-fast deployment of LED strips and pixel dot systems. What’s more, the OCTO Mk2 is compatible with almost every SPI LED tape due to custom protocols and an industry-leading voltage input range.

Its installer-friendly features include an identify button to check correct wiring without a data source, temperature monitoring, and an intuitive configuration and management through its localhost web interface. In addition, the flexible TS35 DIN rail or surface mount options and network chaining make the OCTO Mk2 the ultimate go-to LED pixel control device.


  • Supports a wide range of LED strips and dots
    • Each OCTO Mk2 can control up to 8 Universes of pixels (1024 RGBW / 1360 RGB / 4096 W), and more than 20 pixel output protocols in the device with and without a clock line (full list on datasheet). If you are working with a pixel protocol that is outside of this selection, custom protocols allows you to create your own protocol for the desired pixel type, anytime (two key criteria apply) without having to submit a support request for new firmware.
      If the manufacturer changes the protocol settings or you are working with lights that have a different protocol to ones supported, you simply connect to your OCTO’s interface and change the settings yourself.
      ENTTEC has created a “Custom Protocol Creation Guide” to guide you through the process which you will find in the downloadable documentation section.
      Note: This is only available on OCTOs with serial numbers 2374307 onwards
  • Perfect for tight spaces
    • The OCTO Mk2’s compact case is capable of being surface mounted in various orientations, or fitted to a TS35 DIN rail using the DIN clip accessory included in the box.
      In addition, the two network ports on the OCTO Mk2 allow multiple units to be chained together with a maximum cable length of 100m between devices to dramatically cut down the number of cable runs required. Up to 50 OCTO Mk2’s can be linked per chain, though ENTTEC recommend no more than 8 per chain for optimum visual synchronization.
  • Professional networking
    • The OCTO Mk2 supports Art-Net, sACN & KiNet™ inputs to give flexibility to your project. ArtSync to ensure all pixel and DMX outputs on projects are synchronized to stop any chance of image tearing.
      The OCTO Mk2 allows either DHCP of Static IP configuration to suit your use case.
  • Web configuration
    • The OCTO Mk2’s intuitive web-based configuration gives you access to configure, update and monitor the temperature using your preferred browser from anywhere on the network.
      And, to save the number of input channels required from your control software, the OCTO Mk2 features a grouping functionality to reduce input channel count whilst still controlling up to 8 Universes of LED pixels.
  • Wide voltage range
    • Whether you want to control 5V pixel tape or 60V pixel dots, the OCTO Mk2 can do it all. With its wide voltage input range, giving the flexibility to power it directly from the same source as your LED pixels. 
  • Smart features
    • The Test/Reset button allows installers to quickly check wiring is correct without requiring a network connection. Simply press the button for the output to be illuminated white for 10 seconds.
      What’s more, the OCTO Mk2 features a pixel grouping function perfect for reducing the control channel count of your installation whilst still controlling the same quantity of pixels.
