《解析媒体矩阵(MediaMatrix)(三十四)DEVICE(路由器及PASHA外部控制协议)的原理和使用(32)》[1]中讲了PASHA外部控制协议是MWare利用串口通信连接到外部第三方设备使用的通信协议。从工业应用来说,一些程序工程师宁愿使用稳定可靠的串口通信,而不愿意使用TCP/IP网络通信类型。但现在的很多工程应用了外控设备和被控设备之间距离比较远,数据量比较大,这些都是使用串口通信最薄弱之处。另外
“The principles and use of MediaMatrix (34) DEVICE (Router and PASHA External Control Protocol) (32)” [1] states that the PASHA external control protocol is used by MWare to connect to external third-party devices using serial communication Communication protocol used. For industrial applications, some programmers prefer to use a stable, reliable serial communication rather than a TCP / IP network type of communication. But now a lot of engineering application of the external control device and the distance between the controlled device is relatively far, the amount of data is relatively large, these are the weakest place to use serial communication.
