Pixel colors or intensity are sent directly from the media server to the panels through the ArtNet protocol (DMX over Ethernet) which, if needed, can easily be converted into a standard DMX signal using simple Ethernet-DMX node.
The LED Mapper extension allows you to import your own mapping of LED devices into MediaMaster and makes it possible to control many of them from a single MediaMaster server (the only limitation being the 256 DMX universes).
To create and edit your panel configurations (mappings), the LED Mapper extension features an external editor that allows you to pick devices from an extensive library and place them interactively on the screen. While editing the mapping configuration, you can view the result of your configuration in real time as it is sent over artnet to your LED panels (supports pictures only).
Once happy with your mapping, you can save it to a file and import it into MediaMaster which broadcast its output according to your specific configuration.
