A.2 J2 Connector Pinout
The VMICPCI-7055/CPCI-7055RC J2 connector is a 2 mm “Hard Metric”
CompactPCI connector, with five rows of 22 pins each. J2 is required for system
slot SBCs. An additional external metal shield, labeled row F, is also used. This
connector’s controlled impedance minimizes unwanted signal reflections. Figure
below illustrates the J2 connector and the connector pinout.
