USB to 485 converter RS485rs422 to USB serial port module usb to rs485 serial db9 cable driver

The CA-890 is a universal USB/RS-485/422 converter that converts single-ended USB signals to balanced differential RS-422 or RS without the need for an external power supply, USB compatible, RS-422, and RS-485 standards. -485 signal, providing surge protection power per line, and surge voltage generated on the line for various reasons and extremely small inter-electrode capacitance to ensure high-speed transmission of RS-422/RS-485 interface, RS-422, RS- The 485 terminal is connected through the connectors of the RJ-45 and DB9 male connectors. The converter has zero delay automatic transmission and reception conversion, and the unique I/O circuit automatically controls the data flow direction without any handshake signal (such as RTS, DTR, etc.) without jumper setting to achieve full duplex (RS- 422), half-duplex (RS-485) mode conversion, plug and play. Make sure it is suitable for all existing communication software and interface hardware.
    The CA-890 interface converter provides reliable connections for point-to-point, point-to-multipoint communications. Each point-to-multipoint converter allows 32 RS-422 or RS-485 interface devices to be connected, with a data rate of 300. -128000bps with power indicator and data flow indicator to indicate fault conditions. Supported communication methods include USB to RS-422 and USB to RS-485 conversion.
