CANpro/104 User Manual

Common Memory Space Address Selections

Most System boards allow the PC/104 Bus stack to be allocated a portion of the memory address located in the 256K region of memory just below the 1-Meg address boundary (Addresses 0x0C0000 to 0x0FFFFF). Different BIOS’s allow different sized regions to the allocated. The CANpro/104 board requires 8K (8192 bytes) of memory space.

The following table shows the Jumpers required to set up the Base Memory Address within this 256K region.

In = Jumper installed (Corresponding Memory Address bit is = “1”) Out = Jumper removed (Corresponding Memory Address bit is = “0”) [xx] = Corresponding Memory Address bit number
