标题: DSI 数字照明协议介绍
数字调光接口是一个用于大面积照明的通信标准,由奥地利的Tridonic于1991年开发出来。通信原理是采用Manchester 8位编码,包括1位开始位,8位数据位(dimming value),4位停止位。DSI使用单字节进行灯光的光强控制( 0-255 or 0x00-0xFF)。DSI已经广泛的使用,并且此项技术成为DALI协议的前身。

About DSI
Digital Signal Interface (DSI) is a protocol for the controlling of lighting in
buildings (initially electrical ballasts). It was created in 1991 by the Austrian
company Tridonic and is based on Manchester-coded 8-bit protocol, data rate
of 1200 baud, 1 start bit, 8 data bits (dimming value), 4 stop bits, and is the
basis of the more sophisticated DALI protocol. The technology uses a single byte
to communicate the lighting level ( 0-255 or 0x00-0xFF). DSI was the start of
digital lighting communication technology and was the precursor to DALI.

DSI现在很少用了吧,锐高推广过一段时间,可惜遇上了DALI,被欧洲人抛弃了啊~~~
