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)

IPMC Block Diagram

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-
