Product Features
The IPMC712 and IPMC761 are optional modules that provide backward compatibility with
earlier Emerson products using the MVME761 or MVME712M rear transition modules.
General Functionality
Both models are designed around a PMC form factor and both modules incorporate a PCI-to-
ISA bridge, Ultra-wide SCSI adapter, and Super I/O functionality. Both modules are single wide,
standard length, standard height PMC boards. They attach to the host board PCI bus via the
PMC P11, P12, P13, P14, and P15 connectors.
■
One single-ended ultra-wide SCSI port
■ One parallel port
■
Four serial ports (2 or 3 asynchronous and 1 or 2 synchronous/asynchronous, depending
on the module)
With this PMC card configuration, the memory mezzanine, one PMC slot, and the PMCspan
are still available, providing support for additional product customization.
IPMC Mode
In IPMC mode, the MVME 6100, MVME5500, and MVME5100 support legacy MVME761 or
MVME712M rear transition modules (with limited PMC I/O) when an IPMC712 or IPMC761
module is installed in PMC slot 1. In this configuration, signals used by wide (16-bit SCSI
conflict with signals that are used by PMC slot 2 rear I/O.
Design Features
The following sections describe the basic features that are incorporated in the design of both
IPMC modules.
PCI Bus Interface
Both modules contain four EIA-E700 AAAB connectors, which provide a 32-bit PCI interface to
an IEEE P1386.1 PMC-compliant host board such as the MVME6100, MVME5500, or
MVME5100.
Connectors P11-P13 on each module provide the 32-bit PCI interface while P14 provides an
I/O path from the module to the host board.
