Overview

BMT-KM3S1 is a multi master one slave serial converter that supports communication between three RS485 master stations and data exchange between one RS485/232 slave station. This device is mainly used to solve the problem of data timing conflicts caused by communication between multiple master stations and slave stations, thereby achieving simultaneous communication between multiple master stations; For example, PLC, computer, and touch screen human-machine interface all need to collect temperature measurement data from multi-channel temperature inspection instruments.
