Product Description:

In order for remote data communication between different standard serial interface to the computer, an external device or smart instrument easy with standard serial interface conversion. Converter compatible with the RS-232C, the RS-485, RS-422 standard, single-ended RS-232 signal conversion for the balanced differential RS-485 or RS-422 signals, conversion is the RS-232 communication distance extend to 1.2 km no external power supply uses a unique "RS-232 charge pump" drive, do not need to rely on to initialize the RS-232 serial port available power supply, with internal zero delay automatic transceiver conversion, unique I / O circuit automatically control data flow direction, without any handshaking signals (such as RTS, DTR, etc.) without the need for jumper settings to achieve full-duplex (RS-422), half-duplex mode conversion (RS-485), in order to ensure the RS-232 full- programs written in the duplex, half-duplex mode without changing can run in RS-422/485 mode, ensure that it meets the existing operating software and interface hardware, the converter transfer rate 300-115.2Kbps. can be applied to the main control between the master microcontroller or peripherals constitute a point-to-point, point-to-multipoint communication network of remote multi-machine, multi-machine response communication. Widely used in industrial automation and control systems, card access control system, parking system, self-service banking system, bus fare collection system, the canteen Shoufan system employees attendance management system, highway toll station system and so on.
