RS232 to RS485 Industrial Converter DB9 Bidirectional

RS232 to RS485 Industrial Converter DB9 Bidirectional Description

Product Introduction The bidirectional interface converter between RS232/RS485 converters, connected to the main control unit. Between machines, the main control computer forms point-to-point or point-to-point connections with microcontrollers or peripheral devices remotely. Multi machine network communication, achieving multi machine response communication, is widely used in industrial automation. Chemical control system, single card, access control system, parking system, self-service banking system, public Car toll system, self-service restaurant food sales system, company employee attendance management system, highway. RS232-RS485 converter, capable of converting TXD and RXD signals from the RS-232 serial port into two and a half duplex RS-485 signals. No external power supply is required, and it can directly steal power from the three pins of the RS-232 port. At the same time, the request is sent by the seven pins (Rts), and the four pin data terminal is ready (DTR) to provide power to the RS 232/RS 485 auxiliary. Automatic flow control eliminates the need to reset, and the hardware and installation software are very simple to use.
