Description
When building a server of desktop system, required interface cards may not always be available in PCI form factor, but may be
available in PMC. Adapting PMC cards to the PCI form factor is the purpose of the adaptPCI-PMC card. The adaptPCI-PMC is a
passive adapter, allowing use of the PMC card’s original software drivers with no interference from transparent or opaque bridges,
or other active bus interface devices. The board outline is a PCI variable length card with a Universal PCI edge connector and 64 bit
extension. The board will seat one PCI Mezzanine Card (PMC) card supporting PN1 through PN4 connections with both 3.3V and
5V signaling. PMC PN4 is connected to a VME P2 type connector using standardized VITA mapping.
The PCI interface conforms to the PCI 2.1 specification PCI 64. Data transfers of 32 or 64 bits at up to 66MHz are accommodated.
Both 3.3V and 5V PCI bus signaling is supported. The board has an optional 3.3V on-board power regulator for older systems that
do not have 3.3V available.
The board complies with the PCI Specification Revision 2.1, and IEEE 1386.1-2001 with the exception of signal trace length.

Installation and Removal
1. Power down the host system.
2. Open the chassis according to your system documentation.
3. Let the power supply cool down, if necessary.
4. Remove the OSS-adaptPCI-PMC from the protective bag, observing proper ESD safety procedures.
Install the PMC Module
1. Press the PMC card’s bezel into the cutout in the adaptPCI-PMC I/O panel. The gasket around the PMC bezel makes a
tight fit to ensure an electromagnetic seal. Check that the bezel and gasket are pressed firmly into the carrier I/O.
2. Press the PMC card down onto the carrier so PN1–PN4 plug into JN1–JN4 on the adaptPCI-PMC.
3. Install four screws to secure the PMC card in place.
4. You may mount a PMC card on either a 32-bit carrier or a 64-bit carrier. However, do not mount a 64-bit PMC card on a
32-bit carrier, and then install it in a 64-bit PCI slot. This violates the PCI specification in regards to REQ64# and ACK64#,
and causes indeterminate results. See PCI Specification 3.2, Section 3.8.1.
Installing the OSS-adaptPCI-PMC:
1. Insert the OSS-adaptPCI-PMC an open PCI slot. The adapter is a universal-keyed 64 bit 3.3V or 5V board.
2. Make sure that the adapter is well seated and tighten the screw.
3. Close the chassis according to your system documentation
4. Attach the ethernet cables.
5. Turn on power to the computer. Adapter installation is complete.
6. Reverse the above procedure to remove the boardSpecifications

Front Panel
The adaptPCI-PMC CompactPCI front panel has custom cut outs with the appropriate thickness to accommodate one PMC bezel
with EMC gaskets.
Bus Keying
Keying on the adaptPCI-PMC is used to prevent damage to the card and/or the backplane. There are two keying systems used on
the adaptPCI-PMC, PCI and PMC.
PCI
As defined in PCI Specification 2.1, PCI 64, the adaptPCI-PMC has the appropriate edge card connector key slots signifying
universal 64 bit PCI card. Because the PCI connector is configured as a Universal PCI card (to allow the adaptPCI-PMC to be
inserted in most PCI bus slots), it is the responsibility of the user to ensure that any mounted PCI card has the correct signaling
voltages from the PCI bus.
PMC Site
As a passive adapter, the adaptPCI-PMC will pass though whatever signaling voltages are present on the PCI bus, there for it is
necessary for the user to supply the required keying posts for a particular PMC/PTMC card. While mounting holes are provided for
the key posts, with the locations defined in IEEE 1386, the posts are not installed on the standard product. Proper key post
installation is the responsibility of the user. Care must be taken to provide the proper keying, or damage could result from
installation of an incompatible PMC or PTMC card.
PCI interface
The adaptPMC supports 32 and 64 bit data transfers up to 66MHz (See Section 2.5 regarding PCI-X). The PCI edge connector
uses universal keying (both 3.3V and 5V keyways are present). Pin assignments for the PCI connector can be found in the PCI 2.2
Specification Table 4-11
PRSNT1# and PRSNT2#
The signals PRSNT1# and PRSNT2# are selectable by installing or removing resistors R20 and R21, located near the PCI
connector pin B11. PRSNT1# and PRSNT2# are used to indicate 7.5W, 15W or 25W card power level requirements. 15W is the
default configuration.

M66EN
The M66EN signal is used to determine the bus transfer speed (33 or 66 Mhz). The M66EN signal is connected directly to the PMC
module. The PMC module controls the M66EN level, and thus controls the bus transfer speed.
PCI JTAG Interface
The TDI and TDO JTAG signals at P1- A4 and P1-B4 are connected to a zero ohm jumper R19. This jumper is installed to continue
the JTAG chain when the card is installed in a PCI slot. This jumper must be removed if the user’s testing requires the need to
break the JTAG chain. All other JTAG signals are no connects
PMC Interface
The adaptPMC supports 32 and 64 bit data transfers up to 66MHz. The PMC site has mounting locations for keying post (both 3.3V
and 5V, not installed). Pin assignments for the PMC connectors Jn1 – Jn3 can be found in the IEEE Specification 1386.1-2001,
Table 1.
PMC JTAG Interface
There is a JTAG TAP connector (J1) as well as an Altera Byte Blaster connector (J2) to provide an interface to the JTAG chain and
device programming on a PMC module. Latest JTAG practice requires that the /TRST signal be pulled low for normal device
operation. The /TRST signal is connected to pin 8 of the Byte Blaster connector through a zero ohm jumper. Install this jumper R8 to
pull up /TRST when programming devices that pull /TRST low. Headers for J1 and J2 are not installed on the standard product.
A modified Byte Blaster cable is required to pull up / TRST.
BUSMODE Signals
The adaptPMC supplies BUSMODE[4:2]# signals to the PMC card. Zero ohm resistor stuffing options for BUSMODE[4:2]# allow for
alternate mode selection. The standard stuffing for BUSMODE# is BUMSMODE4# = 0 , BUSMODE3# = 0 and BUSMODE2# = 1.
BUSMODE1# from the PMC module is observable by an LED. Zero ohm jumpers R9 –R14 configure the mode.

for the mapping by signal name.

Power Supply
5v power is always supplied from the PCI connector. The adaptPCI-PMC may get its 3.3v power from one of two sources, the PCI
bus, or the optional on-board 3.3v regulator which draws its power from PCI +5v. See Error! Reference source not found..
When choosing to draw 3.3V power from the PCI Bus, dual jumper JP1A/B is installed, JP2 A/B is removed. This connects the 3.3V
PCI source voltage directly to the board's 3.3v plane.
The optional on-board 3.3v switching power supply is provided to draw 3.3v power from the 5.0v source that is provided by the PCI
Bus. When choosing this option jumper JP2A/B is installed and JP1A/B removed. With this option selected, 3.3 volts is supplied by
a LT1772B switching buck regulator and support components. The board is capable of supplying up to 12 Watts from the on-board
regulator.
Ground / Frame Ground connection
Zero Ohm Jumper R1 is provided as a means to connect Signal (Digital) Ground and Frame Ground. R1 is not installed in the
default configuration. In practice signal ground and frame ground are normally not connected. The user has the option to connect
the signal and frame grounds if needed by the application.
LEDs and test points
LEDs and test points are provided on the adaptPCI-PMC card to indicate status and to facilitate troubleshooting.
Power LEDs
Green Power Indication LEDS and test points are provided for –12V, +12V, 5V, 3.3V and VIO. The LEDs are located at the top
edge of the card above the PMC connectors and are clearly marked.
BUSMODE#1 LED
The BUSMODE#1 signal is connected to a green LED that lights when BUSMODE#1 is driven low to indicate that a PMC card is
present and PCI capable. A test point is also provided, directly above the BUSMODE#1 LED.
Ground test points
Two test points for ground are also provided. Both test points are located at the top edge of the board, one at the front (GND1), and
the other (GND2) at the rear of the card
Power test points
Power test points are provided directly above the associated power LED
