DMX 512协议是Digital Multiplex的缩写,是灯光行业数字化设备的通用信号控制协议,同时也是是一种国际协议。 USITT DMX512/1990是调光和灯光控制台数据传输标准,是娱乐灯光领域常用的控制协议。以前0-10V模拟控制用的比较多,现在DMX512是娱乐灯光行业最主要的控制协议。USITT DMX512/1990是由美国剧场技术协会USITT提出的。最原始的版本出版于1986年,在1990年做了修改。 (DMX 512 protocol is short for Digital Multiplex is light industry, general-purpose digital signal device control protocol, but also is an international agreement. USITT DMX512/1990 is dimming and lighting control data transmission standard, is commonly used in the field of entertainment lighting control protocol. 0-10V analog control previously used more, now is the entertainment lighting industry, the main DMX512 control protocol. USITT DMX512/1990 by the American Association of Theater Technology USITT s. The original version published in 1986, was revised in 1990.)
