ITEM NAME:USB2.0 to RS-485 RS-422 DB9 pin female COM Serial Port adapter cable converte!e Commercial PL2303 chip USB to RS-485/422 converter Product Description: this section is a universal USB/RS-485/422 converter with no additional power, compatible USB, RS-422, and RS-485 standards. It can convert single end USB signals to balanced RS-422 or RS-485 signals, provide surge protection power per line, surge voltage generated on line on line and minimal electric power. Capacity ensures the high-speed transmission of RS-422/RS-485 interface, and RS-422 and RS-485 terminals are connected by connectors of RJ-45 and DB9 heads. The interior of the converter has zero delay and automatic transfer, and the unique I/O circuit automatically controls the direction of the data flow without any handshake signal (such as RTS, DTR, etc.) without the need for a jump line setting to achieve full duplex (RS-422), half duplex (RS-485) mode conversion, or plug and play. Ensure that it is suitable for all existing communication software and interface hardware. An interface converter can provide a reliable connection for point-to-point, point to multipoint communications, and points to multiple points per converter can allow connection of 32 RS-422 or RS-485 interface devices, data communication rate 300-128000bps, and USB to RS-422, USB to RS-485 conversion. Fully compatible with USB (Universal Serial Bus) Rev 2 Support RS-485/422 interface RS-422/485 interface DB9 pin connector Data (TXD) automatic flow control, zero delay design Data transmission rate above 1Mbps Support automatic handshake protocol Support remote wake-up and power management The USB bus takes power directly without external power supply +/-15KV ESD Antistatic protection Use environment: -25 C to 70 C, relative humidity 5% to 95% Support Win98/Win2000/WinXP/Vista/Win7/Linux and so on Include: 1X USB 2.0 to RS-485/RS-422 Adapter Cable 1X 6 pin Terminal Board 1X Driver CD.Ensure that it is suitable for all existing communication software and interface hardware.
