ISA to USB ISA interface to USB interface Switching card used for industrial control devices1. Product function introduction:
The U disk interface card independently developed by the shop owner, ISA to U disk, ISA to USB ISA interface to USB interface, suitable for XT, 286, 386, 486 and other computers without USB interface external USB disk memory, perfect solution to the ancient computer without native USB port, can not exchange files with modern computers trouble, It can replace the floppy drive to complete the file copy function, and can also replace the CD-ROM to install the CD-ROM software, and facilitate the transfer of important data in the early computer to the new computer. The default I/O port address of the USB flash drive expansion card is 2c0H, and 280H is used after inserting the jumper cap (280H is used when inserting the jumper cap I/O address outside the factory). You need to load the driver in the config·sys file and then it can work normally. If the 280 and 2c0 addresses are not available, you can contact the shopkeeper to change to another address before shipping. ISA to USB card inserted into the iSA expansion slot of the computer, in the DOS operating system to add its DOS device driver, you can drive the U disk as a hard disk, in the DOS system will add a logical disk (usually D disk), the use of similar to the ordinary hard disk and electronic disk and RAM memory disk, the method also supports the U disk with electric plug. Very easy to exchange data.
The updated version V2.4 expands the second USB port for external power supply, and optimizes the circuit to make the operation more stable and reliable.
2, use and characteristics:
1, used for non-real-time data exchange between the computer and the industrial computer/embedded system. 2, used to back up important data in industrial computer/embedded system. 3, the use of common U disk on the market, than flash memory and electronic disk is easy to purchase, unlimited capacity. 4, support DOS 3.X to 7.X versions, support WINDOWS 3.X, WINDOWS 95/98 and other operating systems. 5, support the operating system can support all file systems, such as DOS 7.X can support FAT12/FAT16/FAT32. 6, only need a driver file CH375DOS.SYS, the length is less than 5K, only need about 4K RAM memory after loading. 7, the driver only works when the application reads and writes the U disk, and does not affect the operation of the original DOS system and industrial computer when idle. 8, support U disk electric plug, easy to use, U disk can only be inserted when needed.
3. Product configuration:
The basic version of the product is configured with ISA interface U disk interface card 1 piece, the U disk and other expansion devices and computers used in the product introduction picture are for function introduction, non-commodity standard content. The USb flash drive Boot package is configured as one USB interface card, one memory chip of the boot firmware of the system is started from the USB flash drive (which has been inserted into the adapter card when delivery), and one USB flash drive is supported. The DOC disk boot package is configured with one USb interface card, one 28-core to 32-pin adapter board (welded to the adapter card when delivered), and one DOC disk (8-meter capacity).
4, common problems:
4.1 Can this product be used in the ISA expansion slot extended by book8088 computer or Pocket386 computer? A, this card can be directly used in the ISA expansion slot extended out of the Book8088 or Pocket386 computer, because the original built-in USB expansion port (U disk expansion port) uses 260H, and this card uses 280H or 2C0H, so the IO address does not conflict, after inserting this card, the machine expands out of 2 hard disks. Very easy to test and use. The configuration of the driver in the computer in Config.sys is as follows:
In the picture above, the native USB port address of the book8088 machine is 260, and the port ISA to USB card uses 280H address.
4.2, What are the characteristics of the basic version plus DOC disk? A: The DOC chip onboard the basic +DOC disk is equivalent to the hard disk of the original computer, and the operation characteristics are the same as that of the native hard disk, supporting the DOC read and write operation through INT13. If the machine has its own hard disk, the DOC disk is enumerated as the second hard disk of the computer. The USB interface on this board can be used as a removable disk by loading the driver under DOS after the system is started. 4.3 What are the characteristics of the basic version plus USB Boot boot package? A: The basic version plus USB boot system package is suitable for testing machine functions when the computer has no hard disk and no floppy drive. After the boot system is installed on the USB disk, the system will start from the USB disk when powered on. When booting from a USB flash drive, the locally installed hard disk cannot be enumerated at the same time, and the local hard disk cannot be accessed
