DME Control Module Programming

DME programming is used to change a "basic control unit" into a "programed control unit" by writing operating instructions onto a blank EPROM. Programming is also used to update an existing DME program by writing additional instructions that compliment the existing software. Programming is used on DME M3.X variants.
