5.1 OVERVIEW
The AR-B1474 provides three 32-pin JEDEC DIP sockets which may be populated with up to 3MB of EPROM or
1.5MB of FLASH or 1.5MB of SRAM disk. It is ideal for diskless system, high reliability and/or high-speed access
applications, controller for industrial or line test instruments, etc.
FLASH disk function allows you to directly program the ROM disk without having to purchase any additional
programming equipment. 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 could 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-B1474.
5.2 SWITCH SETTING
We will show the locations of the AR-B1474 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.
