RS232-RS485/422 Converter

Transmission stability: The baud rate is 300BPS-115200BPS, twisted pair or shielded cable, no external power supply is required.
Transmission distance: 15M (RS232), 1200M (RS-485), baud rate: 300BPS-115200BPS.
Asynchronous half-duplex operation: Convert the TXD and RXD signals of the RS-232 serial port into a two-wire balanced half-duplex RS signal, without an external power supply, through the serial port
Remote data communication between computers, external devices, or smart instruments for different standard serial interfaces
