INTRODUCTION:
The PCI-EXT64U and PCIEXT64UB are
high-speed 32/64 Bit PCI Bus Extender Cards ith
s itchable bus isolation s itches supporting 32 and
64 bit PCI Cards (referred to as Units-Under-Test,
or UUTs), as ell as 32 or 64 bit motherboard slots,
operating in either 5V or 3.3V signaling
environments. PCI signal integrity requirements
are met ith high-speed trace layout parameters
(controlled high impedance and lo ground
inductance) and active bus s itching ith lo
capacitance and delay to insure minimal effect on
board under test.
Po er monitoring and current limiting
provide a robust debug and test environment. The
PCIEXT64U/UB’s po er limiting and overload-
disconnect help protect the host system from
damage due to certain malfunctions on the UUT.
The PCIEXT64U/UB have test point
header arrays, ith all host PCI signals, for logic
analyzer hookup or piggyback connection.

Power Limit Switch:
The POWER LIMIT s itch allo s selection of a po er
limit value of 15, 25 or 35 atts. For example, if set to
25W, the PCIEXT64U or UB ill limit the +3.3V, +5V
and VIO current if the UUT dra s more than 25 atts
total on its +3.3V, +5V and VIO po er pins. Note that
the 35 W setting is above the maximum per-slot
power (25 W) allowe by the PCI specification. Also,
the +/-12V power is not protecte from overloa s.
Current Measurement Test Points:
The PCIEXT64U and UB allo real-time measurement
of po er consumption during board operation. A
voltmeter or scope can be connected ith its “+” lead to
either the 5I, 3.3I or VIO hite test points, and its “-“
lead to the black GND test point. The voltage output on
these test points has a 1:1 Volt-to-Ampere
correspondence. Hence, a reading of 2.4V on the 5I test
point indicates that the UUT is dra ing 2.4 amperes
from the 5V supply.
Live (Hot) Insertion:
The Live Insertion capability is enabled by first saving
the UUT’s configuration register contents, using the live
insertion soft are provided, and then s itching the Slot
Po er s itch off, hich removes po er and isolates all
signals to the connector of the UUT.
With the Slot Po er s itch off, a user can then remove
or insert the UUT, or insert a ne UUT of the same type,
ithout the need to po er the host system off. The plug-
in UUT may be modified or s apped ithout po ering
do n the host system.
Then, ith the modified or replaced UUT (of the same
type as the old board) in place, the slot po er s itch may
be turned on again.
S itching on Slot Po er ill require the UUT
configuration register contents to be reinitialized to
operate correctly, again using the live insertion soft are
provided, as described in the section “Live Insertion
Soft are” These configuration registers need to be
initialized prior to re-accessing the board.

You may also use the PCIEXT64U/UB to apply
switchable power to the UUT without turning on the
bus switches. This is done by installing the “DISABLE
BUS SWITCHES ALWYS” jumper. This feature is
useful for avoiding system crashes hile programming
FPGAs on the UUT, although the system cannot
communicate ith the UUT ith this jumper in place.
Installing the PCIEXT64U or
PCIEXT64UB into a system:
To install the PCI extender, po er do n the host
computer and install the PCIEXT64U/UB into a PCI slot.
Secure the exten er using a screw in the metal
bracket. Po er up the host computer. Note that for
proper operation, the PCIEXT64U or UB must be
installe in a PCI slot with all PCI voltages (+5, +3.3,
VIO, +12 an –12V) present.
After insuring that the computer is operating correctly,
po er do n the computer and plug in a known goo
Unit Under Test (UUT) into top of the extender card.
Repeat the po er-up process ith the Slot Power switch
in the on position to verify that the UUT is functioning
correctly. At this point, you may ish to display and
save the configuration register information from the
UUT using the supplie program PCI.EXE (For
Win ows 95, 98, ME an 3.1), or the alternate
program PCINT.EXE (For Win ows XP or 2000) so
that these values may later be re-loaded to a ne (but
identical) UUT after this board is removed.
Use care hen using hot insertion. Remember that po er
up BIOS, configuration space and registers ill not be
loaded or automatically performed on insertion of a ne
UUT unless you use the supplied live insertion soft are
to reload the UUT’s configuration space, as described in
the manual section “Live Insertion Soft are”.
-
DO NOT INSTALL THE +12V an -12V ENABLE
JUMPERS ON THE PCIEXT64U/UB UNLESS
YOUR UUT REQUIRES +/-12V (VERY FEW PCI
BOARDS DO). This ill greatly reduce the chances of
damaging the bus s itches U1 or U2 if you inadvertently
plug in your UUT ithout first turning off Slot Po er.
Such damage to Bus s itches is not covered by the
arranty.
-
DO NOT INSTALL BOARD-UNDER-TEST THAT
HAS DIFFERENT SIGNALLING ENVIRONMENT
VOLTAGE THEN MOTHERBOARD SLOT.
While the PCIEXT64U/UB has been designed to
minimize the chance of damage due to incompatible
signaling environments bet een motherboard and board-
under-test, any Universal Extender, even the
PCIEXT64U/UB, can cause a hazardous situation if the
board-under-test that is installed on the extender is
designed for a different signaling environment than the
PCI motherboard slot that the extender is plugged in to.
For example, if the PCIEXT64U/UB is plugged into a
PCI bus slot in the backplane that has a 3Vsignaling
environment, the board-under-test MUST also be
designed to use a 3V signaling environment, or
alternatively it may be a universal board. This can be
determined by examining the position of the cutouts in
the gold finger regions of the board-under-test.
If the PCIEXT64U/UB is plugged into a motherboard
slot that has a 5V signaling environment, the “LIKELY
SIG. ENV 5V” LED on the extender should light up. In
this case, you may only plug in either a boar -un er-
test esigne for a 5V signaling environment or a
universal boar -un er-test. The PCIEXT64UB’s PCI
connector prevents a 3.3V-only board from being
inserted, and the connector’s eb ensures correct socket
alignment, even ith UUTs ith out-of-spec gold finger
contact areas. It only allo s a 5V or Universal (3.3V
and 5V capable) board to be inserted. In the rare case
that you have a 3.3V-only board-under-test, the
Ultravie PCIEXT64U must be used, but that model is
not recommended for most high-volume applications, due
to the ability for some boards-under-test to be installed in
a misaligned manner.
If the PCIEXT64U or UB is plugged into a motherboard
slot that has a 3V signaling environment, the “LIKELY
SIG ENV 3V” LED should light up. In this case, you
may only plug in either a boar -un er-test esigne
for a 3V signaling environment, or a universal boar -
un er-test. In rare cases you may be also able to insert
a board ith 5V signaling environment (despite the
PCIEXT64U or UB being installed in a 3V slot), but only
in cases in hich you can be absolutely sure that the
boar -un er-test oes not use VIO internally, an
oes not connect it to any other power supply plane.
Even in that case, there is a risk of amaging the
boar -un er-test, so this should only be tried ith
prototype boards that are expendable.

External Power: (Optional and
Risky)
- USE EXTREME CAUTION! -
Slot Power switch must remain in OFF position, an
computer system must remain ON, when using this
mo e or amage to system may result.
An external po er supply can be used to provide the
plug- in UUT po er by use of the 5V, +/- 12V, VIO and
3.3V test point connectors. The Slot Po er s itch MUST
remain off hen an external po er supply is connected to
po er points. Special care must be taken ith an
external po er supply, as po er provided to the plug-in
UUT is not current limited. Also, if the external +5V
(and +3V if used) are belo +4.75V and +2.7V
respectively, the bus s itches ill not turn on, and the
UUT ill not be accessible to the system.
While the use of an external po er supply is valuable for
voltage margin testing of UUTs, it must be done ith
care. Use a multi-output external po er supply hose
voltages all turn on and off as close to simultaneously as
possible. Before removing the UUT, be sure to save the
UUT’s configuration registers using the live-insertion
soft are, and then turn off the external po er supply.
The computer must remain ON. The bus s itches on
the PCIEXT64U or UB ill automatically disconnect the
UUT from the motherboard hen the external 5V (and
3.3V, if present) fall belo the 4.7V and 2.7V thresholds,
respectively. Then, remove your UUT, and replace it
ith another, just as you ould do normally.
When you are ready to start up your ne UUT, turn on
the external po er supply (not the slot po er s itch).
Then, reinitialize the configuration registers, using the
live insertion soft are, and begin to use the ne UUT.
Remember that the SLOT POWER switch on the
PCIEXT64U or UB must always remain off when
using external power. It must never be turne on!

The live-insertion soft are supplied ith the
PCIEXT64U or UB allo s the UUT configuration
register values to be saved after the first board is inserted
into the extender, and then to be re-initialized after the
UUT board is replaced ith an identical type of board.
Installing and running PCI EXE under
Windows 3 1/ 95/98/METM
A diskette ith Windo s3.1/95/98/ME-compatible live
insertion soft are, as ell as a different version for
Windo s 2000/XP is included ith the PCIEXT64UB.
To install the Windo s 95/98/ME version, simply copy
the file A:\WIN95\PCI.EXE to your C:\WINDOWS
directory. To run the soft are, hit the RUN item on the
toolbar, type C:\WINDOWS\PCI.EXE hen asked, and
then click RUN. A good UUT must be plugged into the
PCIEXT64U or UB and the “Slot Po er” s itch on the
PCIEXT64U or UB must be on before doing this.
Finding your UUT’s configuration registers
When PCI.EXE starts up, you ill see a indo ith a
number of smaller indo s in it. Open up this large
indo as ide as possible, by dragging the lo er right
corner of the large indo . Each of the smaller
indo s displays the first 16 configuration registers of a
PCI device. Hence, if there are 8 PCI devices in your
system, you ill see eight small indo s. Note that not
all of these PCI devices are plug-in boards - some are
motherboard PCI chips. One of these win ows is the
configuration space for the UUT that is plugge into
your PCIEXT64U/UB. You ill need to find out hich
of these indo s is the UUT’s. The first register in each
indo (register 0) is the vendor ID number. Click on
each win ow until you see the one which shows the
ven or ID correspon ing to your UUT. If you do not
kno your UUT’s vendor ID, ask the manufacturer.
Saving your UUT’s configuration register
contents and restoring them in a new UUT
Once you have clicked on the small indo for your
UUT, this indo should appear on top of other
indo s. Open your UUT’s indo to expose all
registers, by dragging its lo er right corner do n ards.
You ill see the contents of your UUT’s first 16
configuration registers. A description of each register’s
function is contained in the PCI Local Bus Specification,
although for most applications, it is not necessary to note
the contents of these registers. We just ant to save the
register contents, so that e can po er off and remove
the UUT and then later restore these contents hen
inserting a ne UUT (of the same type).
To save the configuration register contents for your UUT,
and restore them on a ne UUT, do the follo ing:
1) Click on the “Cfg” button.
2) Click on “Read from Ne Bus”. This reads the current
register data from the UUT.
3) You may no turn off the slot power s itch, remove
the UUT and replace it ith a ne UUT.
4) Then, turn the slot power on and restore the ne
UUT’s configuration registers by clicking on “Cfg”
and “Write to Ne Bus”. Be sure you have not
acci entally clicke on a small win ow for a
ifferent PCI evice, or you may write to the
wrong boar an crash the system!
5) Your ne UUT should no be accessible to the
system in the same manner as the old one as.
6) You may test as many identical UUTs as you like,
ithout having to save the register contents each
time. Just turn off the slot po er s itch, plug in the
ne UUT, turn on the slot po er s itch and click on
“Write to Ne Bus” to re-initialize each ne UUT.
You may also use PCI.EXE to manually edit
configuration registers of any PCI device, although this
should only be done for specific debugging purposes.
The contents of any ritable registers may be modified
by clicking on the desired field and typing in ne
contents, and then clicking on “Write to Ne Bus”, to
send the modified data to the UUT.
Every time the system is re-boote , you must have
your UUT in the PCIEXT64U or UB an the slot
power switch turne on for correct live insertion
operation.

Finding your UUT’s configuration registers
When PCINT.EXE starts up, you ill see a indo
entitled “PCI Device List” ith a list of PCI devices in it.
Hence, if there are 8 PCI devices in your system, you ill
see eight items on the list. Not all of these PCI devices
are plug-in-boards - some are motherboard PCI chips.
One of these evices is the UUT that is plugge into
your PCIEXT64U or UB. You ill need to find out
hich of these devices is the UUT’s.
You may be able to recognize the particular device that is
on the extender by its description. Double click on the
name of this device. A ne indo entitled “Edit PCI
Configuration Space” ill appear hich displays the first
16 configuration registers of that PCI device. The first
register in each indo (register 0) is the vendor ID
number. Verify that the ven or ID you see is the
correct one for your UUT. If you do not kno the
vendor ID of your UUT, ask the manufacturer of the
UUT. If the vendor ID you see does not match the one

A detailed description of each register’s function is
contained in the PCI Local Bus Specification, although
for most production applications of the PCIEXT64U/UB,
it is not necessary to note the contents of these registers.
We just save the contents of these registers, so that e
can po er off and remove the UUT and then later restore
these contents hen inserting a ne UUT (of the same
type as the one removed) on the PCIEXT64U or UB.
Saving a UUT’s configuration registers
and restoring them into a new UUT
Once you are in the correct indo (entitled “Edit PCI
Configuration Space”) for your UUT, the contents you
see of the first 16 configuration registers of your
UUT have alrea y been save in a memory buffer,
and you can no turn off the slot power for your UUT,
remove the UUT and replace it ith another UUT.
Then, turn the slot power on and restore the ne
UUT’s registers by clicking on “Write to Device” and
then clicking “OK” in the Write Confirmation indo .
Your ne UUT should no be accessible to the system
in the same manner as the old one as.
You may test as many identical UUTs as you like ithout
having to save the registers each time. Just turn off the
slot power switch, plug in the new UUT, turn on the
slot power switch an click on Write to Device an
then “OK” in the Write Confirmation menu, to initialize
each ne ly inserted device.
Saving the UUT configuration registers to a
file on disk (Optional)
Saving UUT configuration registers to disk is only
necessary if you ill be exiting the PCINT.EXE program
before you s ap UUTs. You may optionally save UUT
configuration register contents to disk (after first clicking
on Probe PCI List and selecting your UUT from the list),
by leaving the “Edit PCI Configuration Space” indo ,
clicking on OK, then clicking on File and then “Save as”.
Then, type in a file to store the configuration data to.
Restoring UUT configuration registers from
a file on disk (Optional)
It is normally not necessary to save information to disk,
although any configuration setup previously saved to disk
may be recalled by clicking “File”, then “Open” and then
selecting the name of the file into hich you had
originally stored your data. A device list should appear.
Click on the evice name for your boar . The “Edit

that the Ven or ID is the correct one for your UUT
and then click on “Write to Device”. If you reboot
your system, o not restore configuration register
contents to a new UUT from the save file, as the
registers are not al ays configured ith the same base
address and other parameters on each boot-up. Each time
you boot up a system, you must freshly save the UUT’s
configuration registers, and use this ne information to
restore the registers on subsequent insertions of the same
type of UUT in that slot.
You may also use PCINT.EXE to manually edit config
registers of any PCI device, although this should only be
done for debugging purposes. The contents of any

User Manual ~ UNIV RSAL PCI BUS XT ND R Model PCIEXT64U and PCIEXT64UB
Every time the system is re-boote , you must have
your UUT in the PCIEXT64U /UB an the slot power
switch turne on for correct live insertion operation.
In Case of Trouble
The most common problems that are occasionally
encountered ith live-insertion extenders are as follo s:
1) System crashes/hangs when slot power turne on.
Some PCI boards do not come up ith all of their PCI
bus lines tristated, as is required by the specification.
These boards may not ork on live insertion extenders.
The PCIEXT64U or UB hold RESET lo until at least
50 PCI clock cycles have been fed to the UUT. Then,
the PCIEXT64U or UB turns on its bus s itches,
connecting the UUT ( hich should still be tristated) to
the motherboard’s PCI bus. Finally, the PCIEXT64U or
UB removes the RESET# signal to the UUT. This
allo s correctly designed PCI bus boards to operate
properly on po er-up on our live insertion extender.
If the system hangs or crashes hen the slot po er s itch
is turned on, the board-under-test may be driving the bus
immediately after its po er is brought up ( hile RESET#
is still asserted) hich is illegal. One ay to remedy the
problem is to redesign the board-under test.
2) System resets when slot power switch is turne on
The po er supplies in some systems have inadequate
reserve capacity to handle the inrush current of some
boards-under-test hen they are s itched on in an active
extender. This may cause the system’s +5V or +3.3V
supplies to dip, causing the system to reset or reboot.
This problem is rare, as the PCIEXT64U or UB has sle -
rate limiting circuitry, causing the supplies to the UUT to
come up smoothly over a 200 us period, reducing UUT
inrush current. If you suspect this problem is
occurring, try the PCIEXT64U or UB in a ifferent
system.
3) System resets or hangs when Configuration
registers are written to by live-insertion software
Some boards-under-test use CPLDs or FPGAs that fail to
initialize correctly due to the controlled sle po er
ramping on the PCIEXTU/UB.
