摘要
首先对数字灯光系统中DMX(Digital MultipleX)512控制协议的数据包格式,特别是定时程序的帧结构作了简单介绍,然后借助一电脑灯的DMX通道表给出了DMX512控制协议的基本作用过程与机理,最后结合DMX512接口的电气特性,对DMX512协议的应用特点和要点,如起始地址码、单元负载及DMX512信号终端器等问题作了分析与说明。
Introduced the data packet of DMX512 control protocol in digital lighting system first, and then, by dint of the a lamp＇ s DMX channel table, analyzed the control process and principle, the final, summarize several essential matters of application, such as, start code, Units of Load and DMX512 signal terminator and so on.
