   In order to facilitate with different standard serial interface of computer and external equipment or remote data communication between intelligent instrument, must carry out the standard serial interface transformation.Converter is compatible with the RS - 232 - c, RS - 485, RS - 422 standard, can be an RS - 232 signal is converted to a balanced differential of RS - 485 or RS - 422 converter to extend the RS - 232 communication distance of 1.2 kilometers, adopt unique without external power supply "RS - 232 charge pump drive, don't need to rely on initialization of the RS - 232 serial port available power supply, internal with zero delay transmit-receive automatically, the automatic I/O circuit control data flow direction, without any handshake signals (such as the RTS, DTR, etc.), do not need to jump line Settings to achieve full-duplex (RS - 422), half duplex mode conversion (RS - 485), to ensure that the RS - 232 full duplex, half duplex mode program without change, you can run under RS - 422/485 way, to ensure that suitable for the operation of the existing software and hardware interface, converter transfer rate of 300-115.2 Kbps. Can be used in between the main control machine, controller and single chip microcomputer constitutes a point-to-point or peripherals, point to multi-point remote multimachine communication network, realize the machine response communication.Widely used in industrial automation control system, IC card, access control systems, parking systems, self-service banking system, charge system, the dining hall meal system bus, company employee attendance management system, highway toll station systems and so on.

The performance parameters:
