I/O Compatibility
Historically, MCG has offered two tracks in its PowerPC VME
portfolio. The first track (which includes the MVME2600/
2700) provides typical single-board computer I/O features
including Ethernet, SCSI, multiple serial ports, a parallel port,
and a single PMC slot. The on-board I/O is routed to P2 and
made available to the user via MCG’s MVME761 or
MVME712M transition boards. The second track (which
includes the MVME2300/2400) offers limited on-board I/O
(Ethernet and a single serial port both via the front panel) but
provides dual PMC slots enabling maximum user I/O custom-
ization.
The MVME5100 merges the best features of both tracks
enabling the OEM to support varying I/O requirements with
the same base platform, simplifying part number mainte-
nance, technical expertise requirements, and sparing.
P2 I/O Modes
The MVME5100 supports two, jumper-configurable P2 I/O
modes, PMC mode and IPMC mode.
PMC mode is backward compatible with the MVME2300/
MVME2400. In PMC mode, 64 pins from PMC Slot 1 and 46
pins from PMC Slot 2 are available on P2 for PMC rear I/O.
In IPMC mode, the MVME5100 supports legacy MVME761 or
MVME712M I/O modules (with limited PMC I/O) when an
IPMC761 or IPMC712 PMC card is populated in PMC Slot 1.
In this configuration, PMC Slot 2 contains some signals that
are reserved for extended SCSI.
IPMC Modules
The IPMC761 and IPMC712 are optional add-on PMC mod-
ules that provide backward compatibility with previous-gener-
ation MCG products (such as MVME2600 and MVME2700)
using the MVME761 or MVME712M transition board. IPMC
modules provide rear I/O support for
• one single-ended Ultra Wide SCSI port
• one parallel port
• four serial ports (2 or 3 async and 1 or 2 sync/async,
depending on module)
With this PMC card configuration, the memory mezzanine,
one PMC slot, and the PMCspan are still available, providing
support for OEM product customization.

MVME761
The MVME761 transition module provides industry-standard
connector access to the IEEE 1284 parallel port, a 10BaseT
or 100BaseT port via an RJ-45 connector, two DB-9 connec-
tors providing access to the asynchronous serial ports config-
ured as EIA-574 DTE, and two HD-26 connectors providing
access to the sync/async serial ports. These serial ports,
labeled as Serial 3 and Serial 4 on the faceplate of the
MVME761, are individually user-configurable as EIA-232,
EIA-530, V.35, or X.21 DCE or DTE via the installation of
Motorola Serial Interface Modules (SIMs).
A P2 adapter provides interface module signals to the
MVME761 transition module. The 3-row P2 adapter can be
used for 8-bit SCSI. A 5-row P2 adapter supports 16-bit SCSI
and PMC I/O.
MVME712M
The MVME712M transition module provides industry-stan-
dard connector access to the Centronics
®
parallel port, a nar-
row SCSI port, and four DB-25 connectors providing access
to the asynchronous/synchronous serial ports jumper config-
urable as EIA-232 DCE or DTE. A P2 adapter provides inter-
