A • Connectors and Pinouts
The VMICPCI-7055/CPCI-7055RC CompactPCI Universal SBCs have several
connectors for their I/O ports. Wherever possible, the VMICPCI-7055/
CPCI-7055RC use connectors and pinouts typical for any desktop PC. This
ensures maximum compatibility with a variety of systems.
Connector diagrams in this appendix are generally shown in a natural orientation
with the controller board mounted in a CompactPCI bus chassis.
A.1 J1 Connector Pinout
The VMICPCI-7055/CPCI-7055RC utilize a high-density 110-pin, low inductance,
controlled impedance connector. This connector meets the IEC-1076 international
standard for CompactPCI connectors. An additional external metal shield is
required. The large number of ground pins ensures adequate shielding and
grounding for low ground bounce and reliable operation in noisy environments.
The key prevents misalignment of the board when installing in the chassis. Figure
below depicts the J1 connector and the connector pinout.
