One of the most common LED/image display devices is the VersaTube (or the LED workhorse, as I like to call it)…VersaTubes work by allowing pixels from an image to be mapped directly to the pixels in the tube. The tubes are connected to one of two types of image processors called a VersaDrive. VersaDrive C1 is more of a stand-alone image processor with content onboard. VersaDrive D2/D3 is the more commonly used processor and allows an external video source to be mapped to the array of Tubes connected to the output ports of the drive. A pixel map must be created using proprietary software called RasterMapper, and it is easily uploaded to the D2/D3 via RS232. Once the map has been loaded, the D2/D3 accepts an incoming video signal and then displays it across the VersaTubes according to how the pixels in the tubes have been mapped.
