Abstract
A system and method distributes data and power in a robust manner for a large scale LED display. Master modules of the display are capable of receiving a data stream on any one of four data ports. The master modules extract the data for its module and an associated group of slave modules from a data stream received on one port and send the received data stream to three other master modules via the other three data ports. Unregulated D.C. power is distributed from one or more power hubs to the master modules which in turn distribute regulated D.C. power to their associated slave modules.
