VMEbus Connector - P1
Two 160-pin DIN type connectors, P1 and P2, supply the interface
between the base board and the VMEbus. P1 provides power and VME
signals for 24-bit addressing and 16-bit data. Its pin assignments are set by
the IEEE P1014-1987 VMEbus Specification and the VME64 Extension
Standard. They are listed in the following table.
