PCI Mezzanine Card (PMC) Interface
A key feature of the MVME240x family is the PCI bus. In addition to the
on-board local bus devices (Ethernet, etc.), the PCI bus supports an
industry-standard mezzanine interface, IEEE P1386.1 PCI Mezzanine
Card (PMC).
PMC modules offer a variety of possibilities for I/O expansion such as
FDDI (Fiber Distributed Data Interface), ATM (Asynchronous Transfer
Mode), graphics, Ethernet, or SCSI ports. For a complete listing of
available PMCs, go to the GroupIPC WorldWideWeb site at URL
http://www.groupipc.com / . The MVME240x supports PMC front
panel and rear P2 I/O. There is also provision for stacking one or two PMC
carrier boards, or PMCspan PCI expansion modules, on the MVME240x
for additional expansion.
The MVME240x supports two PMC slots. Two sets of four 64-pin
connectors on the base board (J11 - J14, and J21 - J24) interface with 32-
bit/64-bit IEEE P1386.1 PMC-compatible mezzanines to add any
desirable function.
Refer to Appendix C for the pin assignments of the PMC connectors. For
detailed programming information, refer to the PCI bus descriptions in the
MVME2400-Series VME Processor Module Programmer’s Reference
Guide and to the user documentation for the PMC modules you intend to
use.
