Pixel Protocol Overview: UCS512B

This pixel protocol was designed by Lianxinke in China. It uses a non-differential DMX512 protocol to drive pixel chips. The control circuit comes in a SOP8 package, allowing for more flexibility with LED choice.

PixLite Support

Are you looking for UCS512B pixel drivers that work with Art-Net or sACN? All PixLite Mk2 and Mk3 products support UCS512B as an available Pixel IC type, so get in touch with us to find out how the lighting specialists at Advatek can support you in your pixel lighting project.

Note: In the Advatek Assistant, select 'DMX512' as your Pixel IC Type. This is the equivalent protocol that will allow you to use UCS512B pixels.

UCS512B Advantages

UCS512B Disadvantages

  • Data-only restricts refresh rates to be limited by the speed of the protocol, which will generally be slow
  • Only 8 bits of data for each color makes dimming curves less smooth
  • No redundancy in data
  • Operation relies on addressing of the pixels to be correct from the factory (See Operational Behavior below)

Operational Behavior

UCS512B will work with the generic DMX512 protocol as is, but this assumes correct factory set addressing of the individual pixels (addressing is usually pre-set at the factory in the pixels themselves). There is also an external addressing line which could allow the team at Advatek to change the addressing via custom firmware development if required - contact the Advatek Support team to find out more.
