Description
USB to RS485/RS422-Serial Port Adapter
USB to RS485/RS422-Serial Port Adapter 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.
