Patent Number:	9378087
Title:	Methods for Improved DMX512 Communication While Maintaining Backwards Compatibility
Abstract:	Disclosed are methods and apparatus for improved backwards compatible DMX communications. In some embodiments, methods and apparatus related to extensions of the DMX protocol enable error detection by enhanced DMX slave devices while maintaining full compatibility with non-enhanced DMX slave devices. The methods and apparatus may utilize a packet checksum byte that is incorporated within a start code packet and that is a checksum of a plurality of bytes in the start code packet. A plurality of bytes within the start code packet may optionally be interleaved according to an interleaving scheme in some variations.
