Duo LED Pixel Control

Supported LED IC Protocol Families

For a complete list of supported LED ICs for ProtoPixel devices, please refer to this article.

Pixel control outputs

The Duo has two independent LED pixel control outputs which can be connected to two separate fixtures or two separate chains of fixtures. Each LED pixel control output can control up to 3600 pixel control channels at 27.8FPS (frames per second), this equates to 1200 RGB pixels per output as each pixel requires 3 channels of control. It is possible to mix and match pixel types within a chain as long as the total control channel count does not exceed 3600.

The table below gives some examples of pixel types and their required control channels to calculate the total pixel control requirement for a set of Pixel fixtures.

Type	Pixel Colours	Channels Required	Max Pixels per Output
WA	White, Amber	2	1800
RGB	Red, Green, Blue	3	1200
RGBW	Red, Green, Blue, White	4	900
RGBWW	Red, Green, Blue, White, White	6	720
RGBWWA	Red, Green, Blue, White, White, Amber	6	600

 

Framerate

The maximum framerate at which the pixels are refreshed is proportional to the number of pixel control channels being driven from the pixel control output.

For example if only 3 control channels are being used for a single RGB pixel connected to the output then the frame rate will be greater than 500FPS (frames per second).

If the control output has the maximum number of pixels assigned and all 2400 control channels are being used then the maximum frame rate achievable is 27.8FPS.

Please note that the Duo controller outputs are configured to control 600 3-channel pixels with a framerate of 50FPS by default. If your installation uses more pixels, do not forget adjusting the output settings in the Duo’s WebApp before testing.
