Overview:
In order to facilitate with the different standard serial interface computer external equipment or intelligent instrument between the long-distance data communication, must carry on the standard serial interface mutual transformation. The converter is compatible with RS-232 and RS-485 standards and can convert single-ended RS-232 signals to balanced differential RS-485 signals. The converter can extend the RS-232 communication distance to 1.2 km without external power supply."RS-232 charge pump"drive, does not need to rely on the initialization RS-232 serial port available power supply, internal with zero delay automatic transceiver conversion, some I / O circuit automatically control the data flow direction, without any handshake signal (Such as RTS, DTR, etc.) to ensure that the program written in RS-232 half-duplex mode can be run without changing RS-485 mode to ensure that the existing operating software and interface hardware, converter transfer rate of 300 -115.2Kbps can be applied between the host computer, the host computer and peripherals between the point-to-point, multi-point multi-point remote multi-machine communication network to achieve multi-machine response communication, widely used in industrial automation Control system, card, access control, parking system, self-service banking system, bus toll system, canteen charging system, employee attendance management system, highway toll station system and so on.
