5.2.10 VMEbus Connectors (P1 & P2) (PMC Mode)
The VME P1 and P2 connectors are 160-pin DINs. The P1 connector provides power and VME
signals for 24-bit address and 16-bit data. The pin assignments for the P1 connector are
specified by the VME64 Extension Standard (refer to Appendix C, Related Documentation, for
the link to this specification).
Row B of the P2 connector provides power to the MVME5500 and to the upper eight VMEbus
address lines, and additional 16 VMEbus data lines. Please read the notes below as they
pertain to the P2 connector.
1. When J28 is configured for IPMC mode, –12V is supplied to P2 pin A30. If there is an
incompatible board plugged into this P2 slot, damage may occur.
2. When J32 is configured for IPMC mode, +12V is supplied to P2 pin C7. If there is an
incompatible board plugged into this P2 slot, damage may occur.
3. J102 – J110 should be configured for PMC 2 I/O to connect PMC slot 2 user I/O from J24
to the P2 connector.
The pin assignments for the P2 connector are as follows:
