Cable Converter Usb To Rs232 Rs485 To Ethernet Rs232 To Usb Converter Usb To Rs232
Ⅰ.Overview
With the continuous development of the PC industry, various large peripheral interfaces (such as DB9 serial port interfaces) of old-fashioned PCs are being gradually canceled, but many important devices in industrial environments need to use RS485 interfaces to achieve data communication, so many users need Use USB to RS232/422/485 converter to realize data transmission between PC and RS232/422/485 devices.
This universal USB2.0 to RS232/422/485 converter does not require an external power supply, is compatible with USB2.0, RS232/422/485 standards, and can convert single-ended USB signals into RS232/422/485 signals, providing The surge protection power of 600W, as well as the surge voltage generated on the line due to various reasons and the extremely small inter-electrode capacitance ensure the high-speed transmission of the RS232/422/485 interface, and the RS232/422/485 port is connected through a DB9 male connector . The converter has zero-delay automatic transmission and reception conversion inside the converter, and the unique I/0 circuit automatically controls the direction of data flow.
The USB to RS232/422/485 converter can provide reliable connection for point-to-point and point-to-multipoint communication, RS485 point-to-multipoint each converter can connect up to 256 RS485 devices, and the RS422/485 communication rate is 300bps Up to 3Mbps, RS232 communication rate 300bps to 115200bps. Products are widely used in industrial automation control systems, access control systems, attendance systems, card swiping systems, building automation systems, power systems, and data acquisition systems.
