l DiskOnChip Installation
6.1 OVERVIEW
The AR-B1462 provides three 32-pin JEDEC DIP sockets which may be populated with up to 4MB of EPROM or
2MB of FLASH or 2MB of SRAM disk. It is ideal for diskless systems, high reliability and/or high speed access
applications, controller for industrial or line test instruments, and etc.
If small page (less or equal 512 bytes per page) 5V FLASHs were used, you could format FLASH disk and copy
files onto FLASH disk just like using a normal floppy disk. You can use all of the related DOS command (such as
COPY, DEL …etc.) to update files on the 5V FLASH disk.
The write protect function allows you to prevent your data on small page 5V FLASH or SRAM disk from accidental
deletion or overwrite.
Data retention of SRAM is ensured by an on-board Lithium battery or an external battery pack that could be
connected to the AR-B1462.
6.2 SWITCH SETTING
We will show the locations of the AR-B1462 switch, and the factory-default setting.
CAUTION: The switch setting needs to adjust with the jumpers setting, make sure the jumper settings and the
switch setting are correct.
