1. Data Exchange: This ISA to USB card is used for non-real-time data exchange between a computer and an industrial computer and embedded system. 2. Widely Compatible: This ISA to USB card supports DOS versions from 3.x to 7.x. Suitable for Win 3.X, for Win 95/98/ME, and other operating systems. 3. Less Than 5K: Only one CH375DOS.SYS driver file is needed, the length is less than 5K, and only 4K is required after loading. 4. Hot Swappable: This ISA to USB industrial card supports hot-swappable U-disks, easy to use, U-disk can only be connected when needed. 5. Stable Performance: The driver program only runs when the application program reads and writes the U-disk, and it does not affect the operation of the original DOS system and the industrial control computer when it is idle.
