IPMC7126E/7616E I/O Module Installation and Use (6806800A45B)
1Product 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-toISA 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
1
■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.
IPMC7126E/7616E I/O Module Installation and Use (6806800A45B)

Chapter 1 Product Features
Signals routed to P14 include: narrow SCSI, parallel port, COM1 and COM2 synchronous serial
ports, COM3 and COM4 synchronous serial ports, power, and P2 mux signals. The remaining
SCSI data lines are routed to P15.
The on-board PCI devices on each module are as follows:
■Winbond PCI-to-ISA Bridge (PIB)
■LSI SCSI device (SYM53C895A)
Configurable Switches
S1 Switch
A 1x4 switch (S1) is provided on each module for configuring GPIO pins 2 and 3. The factory
default setting is for Ultra-Speed and Ultra-Wide SCSI. Refer to Table 3-1 on page 16 for the
GPIO pin assignments and to Figure 3-1 on page 16 for the default switch settings.
S2 Switch
There is a 1x2 switch (S2) on each module that is in line with the PCI-to-ISA bridge for selecting
either AD[11] IDSEL or IDSELB for connection to the Winbond chip, depending on the IPMC
module you are using.
Note The S2 is not dependent on either IPMC module. It is dependent on either the
MVME5100, MVME5500, or MVME6100 host board. The IPMC modules are shipped
configured for these boards.
Details on IDSEL mapping and PCI arbitration assignments for these SBCs can be found in
Chapter 3, Programming. An illustration showing the S2 switch settings can be found in Figure
3-2 on page 17.
PCI-to-ISA Bridge (PIB)
The PIB provides the bridging functions between PCI local bus and the ISA local resource bus.
The following are a few of the features of the PIB.
SCSI
The SCSI controller is an LSI Logic SYM53C895A device. The SCSI clock frequency is 40 MHz.
The SCSI controller features:
■32-bit PCI Interface with 64-bit addressing
■8KB internal SCRIPTS RAM
■Improved PCI caching design (improves PCI bus efficiency)
The SCSI device maintains backward compatibility with the MVME761 rear transition module
and P2 adapter card. It is also Ultra-wide capable and has a performance of 40MB/s
synchronous transfer rate across a 16-bit bus.

Note SCSI signals leading to connector P15 go through zero ohm resistors (R92-R100) before
terminating at P15. When the host board’s PMC slot 2 is populated, and there is an IPMC
module in slot 1, there exists a possibility for contention on these signals.

Chapter 1 Product Features
ISA Local Resource Bus
PCI-to-ISA Bridge (PIB)
The PIB (W83C554F) contains the ISA Bridge I/O Registers necessary for various functions.
These registers are also accessible from the PCI bus.
Super I/O
The Super I/O device (PC97307) provides the following functions on the IPMC:
■Two synchronous serial ports (COM1 and COM2)
■Parallel printer port
ESCC
Two DTE synchronous/asynchronous serial ports are provided by the ESCC device (Z85230).
Since the Z85230 device does not have all modem control lines, a Z8536 CIO device (described
below) is used to provide the missing lines.
A PAL device is used to perform decode for the Z85230 and the Z8536 for register accesses
and pseudo interrupt acknowledge cycles in the ISA I/O space. DMA supports for the Z85230
is provided by the PIB.
The clock input to the Z85230 PCLK pin is a 10 MHz clock. The Z85230 supplies an interrupt
vector during a pseudo interrupt acknowledge cycle. The vector is modified based upon the
interrupt source within the device.
All modem control lines from the ESCC are multiplexed/demultiplexed through connector P2 by
the P2MX function due to pin limitation of the connector.
CIO
The CIO device (Z8536) is used to provide the modem control lines not provided by the Z85230
ESCC. In addition, the device has three independent 16-bit counters/timers. The clock input to
the Z8536 PCLK pin is a 5 MHz clock.
Static ROM (SROM)
Both modules contains one +3.3V, 256 x 8 serial EEPROM device (AT24C02) onboard. This
device provides for Vital Product Data (VPD) storage of the module hardware configuration. The
serial EEPROM is located on the baseboard’s I
2
C bus at address $A4.
8
IPMC7126E/7616E I/O Module Installation and Use (6806800A45B)
Input/Output Modes
Both modules are designed to be plugged into PMC slot 1 of the base board. As stated earlier,
these SBCs have two P2 I/O modes (IPMC and PMC) that are user configurable. The user
should configure the baseboard for the IPMC module being used.
The jumpers route the on-board Ethernet port 2 to row C of connector P2. When used, both
modules are backwards compatible with the MVME761 rear transition module and P2 adapter
card (excluding PMC I/O routing) used on the MVME2600/2700. The rear panel Ethernet is not
available when using the IPMC712.
LEDs
Both modules use two LEDs to provide PMC status.
■The module’s green SCSI LED is lit when the SCSI device is Master
■The module’s green PIB LED is lit when the PCI bus grant to the PIB is asserted
Chapter 1 Product Features
PCI Signaling Voltage Level
Both modules will operate with only +5V signaling levels.
RS232 Interface
On the IPMC712 module, the four serial ports are used to communicate at RS232 voltage levels
(P14). The first three ports are fixed asynchronous ports, while the remaining port can be
configured as either a synchronous or an asynchronous port.
For additional handshaking signals, the IPMC712 module has the following features:
■Port 1 has RTS and CTS
■Ports 2, 3, and 4 have RTS, CTS, DTR, DCD
■Port 4 has configurable serial clock signals RTxC and TRxC
Jumpers J2, J3 and J5 determine the sources for these two signals, refer to Figure 1-5 on
page 7.

2Installing the IPMC Module
This chapter discusses the configuration and installation of IPMC modules on an MVME6100,
MVME5500, or MVME5100 SBCs.
For additional information pertaining to the MVME51005E, refer to the information contained in
the MVME51005E Single Board Computer Installation and Use manual before proceeding with
these instructions contained in this chapter.
Packaging
As a precautionary measure, IPMC modules are sealed in an anti-static package to protect
them from static discharge. Observe standard handling practices of static sensitive equipment.
2
Configuring the IPMC Modules
There are two user configurable switches on the IPMC712 and IPMC761 I/O modules. Switches
S1 and S2 are described in Chapter 3, Programming.
Installing IPMC Modules on Host Board
Both the IPMC712 and the IPMC761 modules are installed on PMC slot 1 of the host board. As
a general reminder, IPMC modules must be installed on the host board prior to installing it into
the VME chassis.
To install an IPMC module, refer to the following figure and proceed as follows:
1. Inspect the host board and the IPMC module for evidence of any damage to the PCB itself or
for evidence of any damage on the mating connectors.
2. If the host board is installed in a VMEbus card slot, carefully remove it and place it with
connectors P1and P2 facing you.

Wrist Strap
3. Remove the filler plate from the host board’s front panel. Position the IPMC module over the
center area of the slot 1 connectors as follows:
Figure 2-1. IPMC Installation
4. Line up the IPMC module’s front panel into the IPMC filler cutout slot on the host board’s front
panel.
5. Align connectors P11, P12, P13, P14, and P15 on the IPMC module with the mating connectors
on the host board and press firmly into place.
6. Insert the appropriate number of Phillips screws (typically 4) from the bottom of the host board
into the standoffs on the IPMC module and tighten the screws.
The host board is now ready to be installed into a VME chassis.
Before You Install or Remove a Board
Boards may be damaged if improperly installed or handled. Please read and follow the
guidelines in this section to protect your equipment.
Observe ESD Precautions
ESD
Emerson strongly recommends that you use an antistatic wrist strap and a conductive
foam pad when installing or upgrading a system. Electronic components, such as disk
drives, computer boards, and memory modules, can be extremely sensitive to
electrostatic discharge (ESD). After removing the component from its protective
wrapper or from the system, place the component flat on a grounded, static-free
surface (and, in the case of a board, component side up). Do not slide the component
over any surface.
12
If an ESD station is not available, you can avoid damage resulting from ESD by wearing
an antistatic wrist strap (available at electronics stores) that is attached to an active
electrical ground. Note that a system chassis may not be grounded if it is unplugged.

Caution
Watch for Bent Pins or Other Damage
Chapter 2 Installing the IPMC Module
Caution
Bent pins or loose components can cause damage to the board, the backplane, or
other system components. Carefully inspect your board and the backplane for both pin
and component integrity before installation.
ECC and our suppliers take significant steps to ensure there are no bent pins on the backplane
or connector damage to the boards prior to leaving our factory. Bent pins caused by improper
installation or by boards with damaged connectors could void the warranty for the backplane or
boards.
If a system contains one or more crushed pins, power off the system and contact your local
sales representative to schedule delivery of a replacement chassis assembly.
Use Caution When Installing or Removing Boards
When first installing boards in an empty chassis, we recommend that you start at the left of the
card cage and work to the right when cards are vertically aligned; in horizontally aligned cages,
work from bottom to top.
When inserting or removing a board in a slot adjacent to other boards, use extra caution to avoid
damage to the pins and components located on the primary or secondary sides of the boards.
Preserve EMI Compliance
Caution
To preserve compliance with applicable standards and regulations for electromagnetic
interference (EMI), during operation all front and rear openings on the chassis or board
faceplates must be filled with an appropriate card or covered with a filler panel. If the
EMI barrier is open, devices may cause or be susceptible to excessive interference.

Recognize Different Injector/Ejector Lever Types
The modules you install may have different ejector handles and latching mechanisms. The
following illustration shows the typical board ejector handles used with ECC payload cards: (A)
Elma Latching, (B) Rittal Type II, (C) Rittal Type IV. All handles are compliant with the
CompactPCI specification and are designed to meet the IEEE1101.10 standards.
Figure 2-2. Injector/Ejector Lever Types
Each lever type has a latching mechanism to prevent the lever from being opened accidentally.
You must press the lever release before you can open the lever. Never force the lever. If the lever
does not open easily, you may not have pressed firmly enough on the release. If the lever does
not close easily, the board may not be properly seated in the chassis.
To open a lever, press the release and move the lever outward away from the faceplate.
To close a lever, move the lever inward toward the faceplate until the latch engages.
Verify Slot Usage
Caution
Prevent possible damage to module components by verifying the proper slot usage for
your configuration.

The on-board PCI devices on the IPMC712 and the IPMC761 are the PCI-to-ISA Bridge and
the SCSI controller.
The PCI-to-ISA Bridge (PIB)
The PCI-to-ISA Bridge (PIB) provides the bridging functions between PCI local bus and the ISA
local resource bus. Other features contained in the PIB are:
■8259 Interrupt Controller
■ISA DMA support
■Timers and counters
The SCSI Controller
The SCSI controller’s clock speed is 40 MHz. The presence of the SCSI device can be positively
determined by reading the Device ID PCI Configuration Register 0x02 - 0x03. The Device ID is
0x0012.

IDSEL Address Assignments for PCI Local Bus
Legacy IDSEL assignment for the PCI-to-ISA Bridge (PIB) is maintained to ensure software
compatibility between MVME2700 and MVME5100 while functioning in IPMC mode. The
IPMC712 and IPMC761 boards have a switch (S2) that allows you to configure the board for
the correct IDSEL connection to the Winbond chip, as described below:
■Connection to IDSEL, AD[11] on PMC connector pin P11-48 is selected when using the
IPMC 712/761 with ECC VME boards MVME5100 and MVME5500 (boards released prior
to the MVME6100)
■Connection to IDSEL, AD[16] on PMC connector pin P12-34 is selected when using the
IPMC712/761 with the MVME6100 board
■Connection to IDSELB varies according to the base board:

PCI Arbitration Assignments on Host Boards
The IPMC module PCI arbitration is provided by the host board.
MVME5100
The MVME5100 PCI arbitration is performed by the Hawk ASIC on the host board which
supports eight external PCI masters. Included is the Hawk itself and seven external PCI
masters. The arbitration assignments for the IPMC712 and IPMC761, when installed on the
MVME5100, are as follows:

The MVME5500 IPMC module PCI arbitration is performed using logic implemented in
Programmable Logic Devices (PLDs). These arbiters use a rotating priority scheme for fairness
and bus parking and will always be on the GT-64260B. There are no software programmable
modes to these arbiters.
IPMC7126E/7616E I/O Module Installation and Use (6806800A45B)
MVME6100
The MVME6100 IPMC module PCI arbitration is performed by the MV64360 ASIC. The internal
PCI arbiter REQ#/GNT# signals are multiplexed on the MV64360 MPP[31:0] pins. The internal
PCI arbiter is disabled by default (the MPP pins function as general purpose inputs). Software
will configure the MPP pins to function as request/grant pairs for the internal PCI arbiter.
The IPMC module arbitration pairs for the MVME6100 are assigned to the MPP pins as follows;
■MPP pin 8, PCI Bus Grant (PIB device on IPMC module)
■MPP pin 9, PCI Bus Request (PIB device on IPMC module)
■MPP pin 12, PCI Bus Grant (SCSI device on IPMC module)
■MPP pin 13, PCI Bus Request (SCSI device on IPMC module)
Interrupt Assignments
The interrupt architecture for the IPMC712 and IPMC761 is fully compliant with the PowerPlusII
Programming Specification for a single processor board configuration.
Chapter 3 Programming
MVME5100 IPMC Module Interrupt Assignments
Legacy interrupt assignment for the PCI-to-ISA Bridge (PIB) is maintained to ensure software
compatibility between MVME5100 and IPMC761 while in IPMC mode. This is accomplished by
using the on-board IPMC761 connector to route the PIB’s interrupt to external interrupt 0 of the
Hawk’s MPIC.
The MVME5100 Ethernet port 2 is routed to the PIB’s IRQ10 input. The SCSI interrupt on the
IPMC761 is also routed to the PIB at IRQ14. The SCSI device is connected to the INTA# pin
J11-04 of PMC Slot 1. Interrupts are routed to the Hawk from on-board resources as specified
by the module’s programming.
The Hawk interrupt assignments are shown below:

INTA#, PMC2 INTB#, or PCIX INTA#.
MVME5500 IPMC Module Interrupt Assignments
Legacy Interrupt assignments were not maintained on the MVME5500 due to the vastly
different host bridge device (GT-64260) used. The MVME5500 uses the GT-64260 interrupt
controller to handle interrupts internal to the GT-64260 as well as the external interrupt sources.
The GT-64260 us's general purpose pins that are configured by software to act as interrupt
inputs. The following are the IPMC module-related interrupt assignments.

device.
MVME6100 IPMC Module Interrupt Assignments
Legacy Interrupt assignments were not maintained on the MVME6100 because of the vastly
different host bridge device (MV64360).
The MVME6100 uses the interrupt controller integrated into MV64360 to manage the MV64360
internal interrupts as well as the external interrupt requests. The IPMC module interrupts are
routed to the MV64360 MPP pins as follows;
