With the continuous development of the PC industry, USB interface is substituting the old industrial and low speed PC interface, but there are so much important equipment still use the RS422 or RS485 interface in the industrial environment. So many users have to use the USB to RS422 or RS485 converter to realize the data transfer between PC and RS422 or RS485 equipment.
USB to RS422 or RS485 is auniversal converter of USB to RS422 or RS485 which is without addition power supply, compatible with USB, RS422, RS485 standards, It can convert USB signals to a balanced differential RS422 or RS485 signals. Each line has surge protection, and various surge voltage protections. The tiny capacitance distance RS422 or RS485 interface of high-speed transmission. RS422, RS485 connect by RJ45 and DB9 interface. Converter with zero delay automatic transceiver inside, unique I/O circuit automatically control data flow direction, without any handshake signals (such as RTS, DTR, etc.) and jumpers set realize full-duplex, half-duplex mode conversion, plug and play. Ensure the product fix for all existing communication software and hardware interface.
USB to RS422 or RS485 converters for point-to-point, point-to-mujlti point reliable communlcations. Provides the point to more each converter allows connecting 32 RS422 or RS485 devices, data rate of 300 to 921600bps. The power and data flow indicator light will show fault if any breakdown. Support of com-munication has USB to RS422 USB to RS485.
