Summary:The utility model discloses a serial communication module. The serial communication module is of a two-out-of-two structure. The two-out-of-two structure comprises two mutually independent serial communication sub-modules; each serial communication sub-module comprises a main processor, a coprocessor and at least two RS422/RS485 transceivers; the main processor communicates with the coprocessor, and the coprocessor is set to realize UART controller logic; and the main processor is set to logically control the transmitting and receiving direction of one RS422/RS485 transceiver through the UART controller so as to realize an RS485 communication interface or an RS422 communication interface. 本申请公开了一种串行通讯模块，所述串行通讯模块为二取二结构；所述二取二结构包括两个相互独立的串行通讯子模块；每个串行通讯子模块包括主处理器、协处理器、至少两个RS422/RS485收发器；所述主处理器与所述协处理器通信，所述协处理器，设置为实现UART控制器逻辑；所述主处理器，设置为通过UART控制器逻辑控制其中一个RS422/RS485收发器的收发方向，以实现RS485通讯接口或RS422通讯接口。
