ISA To USB Card Computer ISA-2USB Card ISA to U disk ISA interface to USB interface adapter card for industrial control

1.Product function introduction:

ISA to USB, ISA to USB ISA interface to USB interface, suitable for external USB storage of computers such as XT, 286, 386, 486 without USB interface, perfectly solves the trouble that old computers do not have native USB ports and cannot exchange files with modern computers, and can replace floppy drives to complete file copying, software installation, and important data transfer functions.

The default IO port address of the USB expansion card is 2c0H, and 280H is used after the jumper cap is inserted (the IO address is set to 280H when the jumper cap is inserted in the factory).The user needs to load the driver in the config·sys file to work normally.

If the 280 and 2c0 addresses are not available, you can contact the shopkeeper to change them to other addresses before delivery.

After the ISA to USB card is inserted into the computer's iSA expansion slot, add its DOS device driver under the DOS operating system to drive the U disk as a hard disk.A logical disk (usually D disk) will be added in DOS.The usage method is similar to that of ordinary hard disks, electronic disks and RAM memory disks.This method also supports hot plugging of U disks with power on, which is more convenient for exchanging data.

2.Uses and features:

1.Used to exchange data between computers and industrial computers/embedded systems in non-real time.

2.Used to back up important data in industrial computers/embedded systems.

3.Use common U disks on the market, which are easier to purchase than flash memory and electronic disks, and have unlimited capacity.

4.Support DOS 3.X to 7.X versions, support WINDOWS 3.X, WINDOWS 95/98/ME and other operating systems.

5.Support all file systems supported by the operating system, for example, DOS 7.X can support FAT12/FAT16/FAT32.

6.Only one driver file CH375DOS.SYS is needed, which is less than 5K in length and only requires about 4K of RAM memory after loading.

7.The driver only works when the application reads and writes the USB flash drive, and does not affect the operation of the original DOS system and industrial computer when idle.

8.Supports hot plugging of USB flash drives, which is convenient to use.The USB flash drive can be plugged in only when needed.

3.Product configuration:

This product is configured with 1 ISA interface USB flash drive interface card.The USB flash drives and other expansion devices and computers used in the product introduction pictures are for function introduction and are not standard product content.

4.Frequently asked questions:

4.1.Can this product be used on the ISA expansion slot expanded by the book8088 computer or Pocket386 computer?

Answer: This card can be used directly on the ISA expansion slot of Book8088 or Pocket386 computer. Because the built-in USB expansion port (U disk expansion port) of the original machine uses 260H, and this card uses 280H or 2C0H, there is no IO address conflict. After inserting this card, the machine expands 2 hard disks, which is very convenient for testing and use.
