PC/104-Plus (PCI part)
The EPIC/CE offers the PC/104-Plus bus on a quad-row female connector with a 2mm x 2mm (0.79” x
0.79”) pitch. This connector implements the standard 32-bit PCI bus signals.
7.2.1
PC/104-Plus Connector
You can only use PC/104-Plus adapter boards on top of an EPIC/CE.
The PC/104-Plus bus is available through Connector J8.
A description of signals, including electrical characteristics and timings, is beyond the scope of this
document. Please refer to the official PCI bus and PC/104-Plus specifications for more details.
Warning: EPIC-CE in 5V-only version supply the +3.3V to the PC/104-Plus connector via an onboard DC/DC
converter. The DC/DC converter is only capable to supply a maximum of 500mA to +3.3V extension
cards. As there is no protection on this +3.3V supply, the user has to make sure not to exceed this value
with his PC/104-Plus add-on cards.
7.2.2
PC/104-Plus Configuration
Add-on boards on the PC/104-Plus bus have to be associated to a “PCI-slot.” Make sure that there are no
resource conflicts in the system. Carefully choose PCI interrupts, REQ/GNT pairs, and IDSEL for the add-
on board. See the technical manual of the add-on board for more details.
The EPIC/CE’s PCI bus can be configured to optimize your system. See the PCI Configuration Submenu in
Appendix B: BIOS for more information on configuration.
