Introduction to RS485 RS232 , RS422 , RS423 and RS485 are serial communication methods for computers and devices. RS232 is without doubt the best known interface, because this serial interface is implemented on almost all computers available today. But some of the other interfaces are certainly interesting because they can be used in situations where RS232 is not appropriate. We will conce

煤矿RS485监控线路复用技术
对于煤矿安全来说,监控技术很重要,当前煤矿监控有一部分以RS485总线为基础。由于监控的参数不同,设备制造商的不同,这些RS485很难结合起来。基于此,提出了一种以以太网线路为基础,在不破坏原有RS485的情况下,把原有RS485结合起来,通过一条以太网线路传输的技术,这样可以避免多条RS485线路同时存在,线路维护难的特点。
