A • Connectors and Pinouts
The CPCI-7806/CPCI-7806RC CompactPCI Universal SBC has several connectors
for its I/O ports. Wherever possible, the CPCI-7806/CPCI-7806RC uses 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 CPCI-7806/CPCI-7806RC utilizes a high-density 110-pin, low inductance, and
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
A-1 below depicts the J1 connector and the connector pinout.
