Mini RS-232 to RS-485 Converter

GM-10211-B converter is compatible with RS-232C and RS-485 standards. It converts RS-232 signals into balanced differential RS-485 signals. The transmission distance of an RS-232 communication can be extended to 1.2km. It adopts unique “RS-232” signals to drive the system and gains power without initializing the RS-232 serial port. Built-in zero delay auto receiving and transmitting conversion and unique I/O circuit auto control data flow direction without any handshake signal (RTS, DTR); this guarantees that there is no need to modify the programming under RS-232 half-duplex mode, it will run smoothly under current software and hardware. The transmission rate is 300-115.2kbps. It can be used between hosts, host and SCM, which building a point to point, point to multipoint long-distance communication networking. It is widely applied in an industrial automation control system, all-in-one card, access control systems, parking systems, ATM systems, bus charging systems, canteen ticketing systems, attendance systems, and toll station systems, etc.
