6.3 JUMPER SETTING

Before installing the memory into memory sockets MEM1 through MEM3 (U31, U32 and U33 respectively), you have to configure the memory type which will be used (ROM/RAM) on the AR-B1375 and AR-B1376. Each socket is equipped with an jumper to select the memory type.

You can configure the AR-B1375 and AR-B1376 as a (FLASH) EPROM disk (ROM only), a SRAM disk (SRAM only) or a combination of (FLASH) EPROM and SRAM disk.

It is not necessary to insert memory chips into all of the sockets. The number of SRAM chips required depends on your RAM disk capacity. The number of EPROM chips required depends on the total size of files that you plan to copy onto the ROM disk and whether or not it will be bootable.

Insert the first memory chip into MEM1 if you are going to configure it as a ROM or SRAM disk. If you use a combination of ROM and RAM, then insert the (FLASH) EPROM chip starting with the MEM1, and insert the SRAM chips starting from the first socket which is configured as SRAM.

zM1:is used to configure the memory type of MEM1

zM2:is used to configure the memory type of MEM2

zM3:is used to configure the memory type of MEM3

CAUTION: When the power is turned off, please note the following precautions.

1.If your data has been stored in the SRAM disk, do not change the jumper position or data will be lost.

2.Make sure jumpers are set properly. If you mistakenly set the jumpers for SRAM and you have EPROM or FLASH installed, the EPROM or FLASH will drain the battery’s power.
