DMX-512 Master component
A serial based communications protocol designed for controlling theatrical equipment such as dimmers, fog machines and intelligent lights. DMX-512 Slave devices are daisy chained together with a final 180R terminating resistor at the end of the chail. DMX requires the signal to be level shifted from VCC and GND to +2.5V and -2.5V.
