NOTE
Backplane designs should route P3 signals straight through to rear J3. Then VMIACC-7055/
ACC-7055RC boards can then be utilized. Although the two Gigabit Ethernet ports are available on the
VMIACC-7055/ACC-7055RC, they can only be used when the VMICPCI-7055/CPCI-7055RC have a value
of ‘1’ in the options’ D field, which allows for Ethernet via CompactPCI J3 (not PICMG 2.16 compatible).
Contact Sales for ordering information.
A.4 J5 Connector Pinout
The VMICPCI-7055/CPCI-7055RC J5 connector is a 2 mm “Hard Metric”
CompactPCI connector, with five rows of 22 pins each. An additional external
metal shield is also used, labeled row F. This connector is used to route the I/O
signals of PMC Site #1, and the IDE signals to the backplane I/O. This connector’s
controlled impedance minimizes unwanted signal reflections. Figure below
illustrates the J5 connector and the connector pinout.
