Описание товара
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.
