A 10-pin 0.100" planar connector provides the interface to a second
asynchronous serial debug port. The pin assignments for this connector are
as follows:
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 D, 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.
The pin assignments for the P2 connector are as follows:
