VME bus compatible backplane and shelf arrangement

摘要

A VME Bus Compatible backplane and shelf arrangement is provided which incorporates a connectorized backplane arrangement which provides for direct mating to both industry standard VME bus cards as well as VME transition cards. A backplane is provided that is double-sided. On a first face, access to two VME busses (P1 & P2) is provided via rows of first and second connectors. The connector of each row are evenly spaced along the bus and the connectors of one row are vertically aligned with the connectors of the second row. On the second face a third row of connectors is provided, directly behind the second row with each connector offset with respect to a corresponding second connector. The first and second rows of connectors accept standard VME bus cards. The third connectors accept directly, industry standard transition cards. Some of the conductors in the second connectors are connected to the second bus, while others are connected directly to conductors in the third connectors.
