[QUOTE="i13, post: 121985, member: 21708"] If your display is entirely pixels then you will use E1.31 and not DMX512. I have seen a display of ~100,000 pixels using E1.31 and multiple controllers on the same network. The Falcon and Advatek controllers use E1.31 and the BeagleBone based controllers can be set up to use it in bridge mode. BeagleBones can also send out E1.31 signal to other controllers but they need USB audio. I understand that another option is to use an attachment to a Raspberry Pi for a small number of pixels but it is not my area of expertise. The Raspberry Pi can send out E1.31 signal to other controllers too along with audio. You will need a controller of some description in order to run pixels. Pixel controllers are different to controllers which control traditional LED strings. Each pixel is powered continuously and the pixel controller sends data to the pixels so that they know when to turn themselves on and off. If you power a typical pixel controller with a 12V power supply, this will allow you to power 12V pixels through the controller. Once you exceed the limit of the number of pixels that can be powered at one end (around 100 pixels if they are 12V), you will need to connect the string of pixels directly to a power supply so that voltage drop doesn't cause a problem. If you power a pixel controller with 12V, you can't power 5V pixels directly through the controller. You can still use the same 12V controller to supply data to 5V pixels but you'll need to connect the 5V pixels directly to their own power supply. Here's a diagram with pixel strips but it would be the same with nodes: [URL]https://auschristmaslighting.com/attachments/powering-example-png.16394/[/URL] In this diagram, the controller and the two power supplies can be different voltages. The pixels get their data from the controller and their power from the power supplies. I look forward to seeing your shopping list. [/QUOTE]

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