52 VMIVME-7805/VME-7805RC Hardware Reference Manual
A • Appendix A: Connectors and Pinouts
The VMIVME-7805/VME-7805RC VME SBCs have several connectors for their I/O
ports. Wherever possible, the VMIVME-7805/VME-7805RC 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 VME chassis.
A.1 VME Connector Pinout (P1 and P2)
Figure A-1 shows the location of the VME P1 and P2 connectors and their
orientation on the VMIVME-7805/VME-7805RC. Table A-1 shows the pin
assignments for the VME connectors. Note that only Row B of connector P2 is
used; all other pins on P2 are reserved and should not be connected.
