说明：  DMX512协议最先是由USITT（美国剧院技术协会）发展成为从控制台用标准数字接口控制调光器的方式，但是传统上的信号传输依赖于485接口方式的双绞线，在使用灵活上大打折扣！而基于TCP/IP的无线传输由于时延大，控制数据实时性差等，也很难满足需求
(DMX512 protocol is the first USITT (United States Association of Theater Technology) to develop into from the console using a standard digital interface control dimmers way, but traditionally dependent on the signal transmission means 485 of the twisted pair, the reduced flexibility in the use of ! And based on TCP/IP wireless transmission delay due to large, poor real-time control data, it is difficult to meet demand)
