Description
The GM-1042E-B converter is compatible with RS-232C, RS-485/422 standards. It converts RS-232 signals into balanced differential RS-485 or RS-422 signals. The transmission distance of RS-232 communication can be extended to 1.2km. It adopts a unique “RS-232” charged signal to drive the system and gains power without initializing the RS-232 serial port. Featuring 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 full-duplex or half-duplex mode, it will run smoothly under RS-485/422 mode, ensure to suitable for 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 industrial automation control systems, all-in-one controller cards, access control systems, parking systems, ATM systems, bus charging systems, canteen ticketing systems, attendance systems, and toll station systems, etc.
