Expansion Bus
Expansion Bus
The
EPM-CPU-10
will accept up to four PC/104 and/or four PC/104-Plus expansion modules. Both
3.3V and 5.0V modules are supported.
PC/104-P
LUS
PC/104-Plus modules can be secured directly to the underside of the
EPM-CPU-10
The first added
module (closest to CPU) is called "Slot 0", the next module is "Slot 1". Make sure to correctly
configure the "slot position" jumpers on each PC/104-Plus module appropriately.
The BIOS automatically configures the I/O ports and Memory map allocation, including
allocation of interrupts.
PC/104
PC/104 modules are stacked under the
EPM-CPU-10
(under any PC/104-Plus modules); 16-bit
modules first followed by 8-bit PC/104 modules. If necessary, a 40-pin and 64-pin ISA
feedthrough connector "extender", and long standoffs may need to be used to provide adequate
clearance between the PCI connector and the components on the top side of the PC/104 module.

ONFIGURATION
PC/104–
Plus
Modules
No configuration is necessary except to jumper the expansion module for the correct slot number.
PC/104 Modules
PC/104 I/O modules should be addressed in the 100h – 3FFh address range. Care must be taken
to avoid the I/O addresses shown in the On-Board I/O Devices table on page 39. These ports are
used by on-board peripherals and video devices.
