The company according to market demand, USB converter on the basis of the original upgrade. Especially in the industrial automation needs of the application, Zhenxin communications company launched a new quality and cheap USB to more serial port hub function products, specific products are 4, 8, 16, 32 and 64 USB switch 232 / 485/422 serial cable hub. Products have been launched by the majority of the market welcome. Especially with the peer, continue to adopt a new import industry program, better compatibility, industrial-grade optical isolation and lightning protection design, and the first use of dual power supply. The price of similar products to the market the most cost-effective.
USB to serial port hub specifically designed to solve the problem of computer serial shortcomings produced in the industrial field there are many RS-232 serial terminal need to exchange data with the computer, and the existing computer motherboard has been canceled RS-232 serial port, through the USB to serial The hub connects the computer's USB serial port with multiple RS-232 serial ports and the terminal device. The computer software communicates with the corresponding serial device connected through the virtual serial port in the operating system. USB to serial hub is mainly used in the automation of multi-serial device, monitoring system, multi-function scanner, room internal environmental monitoring and management, intelligent community, intelligent building systems, intelligent traffic control systems, industrial control automation. Especially a lot of computers gradually highly integrated. Weakened the PCI / PCIE card slot design, because the serial card is often unstable, resulting in the installation of blue screen, poor driver compatibility, bad installation management and so on. Then use a turn of the USB serial port hub can be easily resolved, stable and efficient, plug and play.
