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 RS-232, RS-422 standard, capable of converting single end RS-232 signal conversion for the balanced differential RS-422 signals, conversion device can be RS-232 communication distance extend to 1.2 km, no external power supply using a unique "RS-232 charge pump driver, do not need to rely on the initialization RS-232 serial port available power, with internal zero delay automatic transceiver conversion, unique I / O circuit automatically controls the data flow direction, without any handshaking signals (such as RTS, DTR, etc.), so as to ensure the programs written in the RS-232 full duplex mode without changing can be run in RS-422 mode, to ensure that suitable for the existing operating software and interface hardware, converter transfer rate 300-115.2Kbps. can be applied to the host computer between, between the host computer and the microcontroller or peripherals constitute a point-to-point, point-to-multipoint communication network of remote multi-machine, multi-response communication. widely used in industrial automation and control systems, card access control system, parking system, self-service banking system, bus fare collection system, canteen Shoufan system, company employee attendance management system, highway toll station system and so on.
