文档介绍：多媒体网络中控效劳器说明
several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate si应代码亦需经中控效劳器上传到触屏。中控效劳器设为TCP效劳端，各网络中控为TCP客户端，主动连接中控效劳器，中控效劳器将实时记录连接的网络中控MAC地址。触屏与中控效劳器的通信可以下面两种方式：
为触屏每一串控制代码打包上要控制的网络中控MAC地址的指定受控端和主控端
several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured

。中控效劳器根据每一数据包的MAC地址查询连接其中的网络中控，将数据转发。
增加一个新的协议数据包〔指定受控端和主控端〕，用该协议包指定触屏即将操作的网络中控。当触屏首先发送这一数据包时，中控效劳器利用数据包中的MAC查询连接其中的网络中控，将该中控作为当前操作中控，以后触屏发的所有控制代码均由中控效劳器发往
