DATA FRAME
Each DMX512 transmitter sends 512
packets of 8-bit dimming values, between 0 and 255, where 0 represents the
lights off and 255 represents the maximum intensity. The DMX512 protocol
requires the transmitter to continuously repeat (at least once a second) the
transmission of a frame as shown in the timing diagram in Figure1 and Table2.
