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
