[QUOTE="Martin Mueller, post: 136227, member: 28228"] DMX has a data rate of 256000 bits per second. WS2811 use 800000 bps. Lets say you use a frame rate of 40fps (25ms). That means you have 256000 / 40 = 6400 bits per frame available to send to the pixel string. 64000 bits available / 24 bits per pixel = 260 pixels per string. Whoops, DMX has its own frame that limits us to a maximum of 512 bps. That means you only get 170 pixels per frame with an impressive 500 frames / second. There are DMX to Pixel controllers, but they are not going to get you any density and that results in a higher per port cost. I have a really bad cold so I suspect I am rambling a bit here. [/QUOTE]

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
