The tSH-735i module is a serial port sharer with 3 RS-485 ports that provides a number of functions, including "Baud Rate Conversion", "Modbus RTU/ASCII Conversion" and "Two Masters Share One Slave". It has a built-in web server that provides a configurable interface. No console commands are required.
This device has Baud Rate and Modbus RTU/ASCII Conversion features. The Baud Rate Conversion makes it possible communication between master and slave devices. It allows for differences in baud rates and data formats to be sent. Modbus RTU/ASCII Conversion allows for a single Modbus RTU master device to communicate with Modbus RTU/ASCII slave devices through different protocols, baud rates, and formats.
