Onchdbfhuu USB to RS485/RS232 Communication Module Bidirectional Half-Duplex Serial Line Converter

Product type: Industrial grade USB to RS485/232 converter; Communication rate: 50bps~1000000bps; Host interface: USB; Device interface: RS485/RS232 (switched by DIP switch) The on-board self-restoring fuse and protection diode can stable output of current and voltage, prevent overcurrent and overvoltage, and improve impact resistance.There are three LED indicators on the board for easy viewing of the power signal sending and receiving status. Support USB to RS485/RS232 communication (switched through DIP switch). Using the new CH343G chip, plug and play, compatible with series, MacOS series, Linux and other systems.The on-board (transient voltage ) can effectively suppress surge voltages in the circuit, instantaneous voltages, and protect against static electricity. USB interface:Working level: 5V, Interface form: USB-A type interface, Interface protection: 200MA recovery fuse, ESD static protection, Transmission distance: about 5 meters
