VMEbus Connector – P2
Row B of the P2 connector provides power to the MVME240x, the upper
eight VMEbus lines, and additional 16 VMEbus data lines as specified by
the VMEbus specification
. Rows A, C, Z, and D of the P2 connector
provide power and interface signals to a transition module, when one is
used. The pin assignments are as follows:
25 Not Used VA6 VIRQ6∗ VA13 Not Used 25
