INTRODUCTION:
The PCI-EXT64U and PCIEXT64UB are
high-speed 32/64 Bit PCI Bus Extender Cards with
switchable bus isolation switches supporting 32 and
64 bit PCI Cards (referred to as Units-Under-Test,
or UUTs), as well as 32 or 64 bit motherboard
slots, operating in either 5V or 3.3V signaling
environments. PCI signal integrity requirements
are met with high-speed trace layout parameters
(controlled high impedance and low ground
inductance) and active bus switching with low
capacitance and delay to insure minimal effect on
board under test.
Power monitoring and current limiting
provide a robust debug and test environment. The
PCIEXT64U/UB’s power 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, with all host PCI signals, for logic
analyzer hookup or piggyback connection.

Power Limit Switch:
The POWER LIMIT switch allows selection of a power
limit value of 15, 25 or 35 watts. For example, if set to
25W, the PCIEXT64U or UB will limit the +3.3V, +5V
and VIO current if the UUT draws more than 25 watts
total on its +3.3V, +5V and VIO power pins. Note that
the 35 W setting is above the maximum per-slot
power (25 W) allowed by the PCI specification. Also,
the +/-12V power is not protected from overloads.
Current Measurement Test Points:
The PCIEXT64U and UB allow real-time measurement
of power consumption during board operation. A
voltmeter or scope can be connected with its “+” lead to
either the 5I, 3.3I or VIO white 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 drawing 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 software provided, and then switching the Slot
Power switch off, which removes power and isolates all
signals to the connector of the UUT.
With the Slot Power switch off, a user can then remove
or insert the UUT, or insert a new UUT of the same type,
without the need to power the host system off. The plug-
in UUT may be modified or swapped without powering
down the host system.
Then, with the replaced UUT (of same type as old)
installed, the slot power switch may be turned on again.
Switching on Slot Power will require the UUT
configuration register contents to be reinitialized to
operate correctly, again using the live insertion software
provided, as described in the section “Live Insertion
Software” These configuration registers need to be
initialized prior to re-accessing the board.

You may control the Slot Power via a software driven
parallel port signal, or other TTL control signal, by
simply installing a small N-channel FET (such as BS170)
as shown in the photo on the previous page. The FET’s
source terminal should be connected to the ground
connection (left terminal of switch) and the drain
terminal connected to the center connection (center
terminal of switch). The TTL control signal should be
applied to the gate terminal of the FET – a HIGH level
on this signal will turn the slot power on, a LOW level
will turn it off. The mechanical SLOT POWER switch
must be left in the OFF position for the external FET to
work properly.
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 while programming
FPGAs on the UUT, although the system cannot
communicate with the UUT with this jumper in place.
Installing the PCIEXT64U or
PCIEXT64UB into a system:
To install the PCI extender, power down the host
computer and install the PCIEXT64U/UB into a PCI slot.
Secure the extender using a screw in the metal
bracket. Power up the host computer. Note that for
proper operation, the PCIEXT64U or UB must be
installed in a PCI slot with all PCI voltages (+5, +3.3,
VIO, +12 and –12V) present.
After insuring that the computer is operating correctly,
power down the computer and plug in a known good
Unit Under Test (UUT) into top of the extender card.
Repeat the power-up process with the Slot Power switch
in the on position to verify that the UUT is functioning
correctly. At this point, you may wish to display and
save the configuration register information from the
UUT using the supplied program PCI.EXE (For
Windows 95, 98, ME and 3.1), or the alternate
program PCINT.EXE (For Windows XP or 2000) so
that these values may later be re-loaded to a new (but
identical) UUT after this board is removed.
Use care when using hot insertion. Remember that power
up BIOS, configuration space and registers will not be
loaded or automatically performed on insertion of a new
UUT unless you use the supplied live insertion software
to reload the UUT’s configuration space, as described in
the manual section “Live Insertion Software”.
-
DO NOT INSTALL THE +12V and -12V ENABLE
JUMPERS ON THE PCIEXT64U/UB UNLESS
YOUR UUT REQUIRES +/-12V (VERY FEW PCI
BOARDS DO). This will greatly reduce the chances of
damaging the bus switches U1 or U2 if you inadvertently
plug in your UUT without first turning off Slot Power.
Such damage to Bus switches is not covered by the
warranty.
-
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 between 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 board-under-
test designed for a 5V signaling environment or a
universal board-under-test. The PCIEXT64UB’s PCI
connector prevents a 3.3V-only board from being
inserted, and the connector’s web ensures correct socket
alignment, even with UUTs with out-of-spec gold finger
contact areas. It only allows 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
Ultraview 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

User Manual ~ UNIVERSAL PCI BUS EXTENDER Model PCIEXT64U and PCIEXT64UB
1/18/2007- REV F COPYRIGHT C 2007 ULTRAVIEW CORP. [phone] www.ultraviewcorp.com
SIG ENV 3V” LED should light up. In this case, you
may only plug in either a board-under-test designed
for a 3V signaling environment, or a universal board-
under-test. In rare cases you may be also able to insert
a board with 5V signaling environment (despite the
PCIEXT64U or UB being installed in a 3V slot), but
only in cases in which you can be absolutely sure that
the board-under-test does not use VIO internally, and
does not connect it to any other power supply plane.
Even in that case, there is a risk of damaging the
board-under-test, so this should only be tried with
prototype boards that are expendable.
External Power: (Optional and Risky)
- USE EXTREME CAUTION! -
Slot Power switch must remain in OFF position, and
computer system must remain ON, when using this
mode or damage to system may result.
An external power supply can be used to provide the
plug- in UUT power by use of the 5V, +/- 12V, VIO and
3.3V test point connectors. The Slot Power switch
MUST remain off when an external power supply is
connected to power points. Special care must be taken
with an external power supply, as power provided to the
plug-in UUT is not current limited. Also, if the external
+5V (and +3V if used) are below +4.75V and +2.7V
respectively, the bus switches will not turn on, and the
UUT will not be accessible to the system.
While the use of an external power supply is valuable for
voltage margin testing of UUTs, it must be done with
care. Use a multi-output external power supply whose
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
software, and then turn off the external power supply.
The computer must remain ON. The bus switches on
the PCIEXT64U or UB will automatically disconnect the
UUT from the motherboard when the external 5V (and
3.3V, if present) fall below the 4.7V and 2.7V thresholds,
respectively. Then, remove your UUT, and replace it
with another, just as you would do normally.
When you are ready to start up your new UUT, turn on
the external power supply (not the slot power switch).
Then, reinitialize the configuration registers, using the
live insertion software, and begin to use the new UUT.
Remember that the SLOT POWER switch on the
PCIEXT64U or UB must always remain off when
using external power. It must never be turned on!

Live Insertion Software for Windows
3.1, 95, 98, ME, 2000 and XP
TM
:
The live-insertion software supplied with the
PCIEXT64U or UB allows 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 with an identical type of board.
Installing and running PCI.EXE under
Windows 3.1/ 95/98/ME
TM
A diskette with Windows3.1/95/98/ME-compatible live
insertion software, as well as a different version for
Windows 2000/XP is included with the PCIEXT64UB.
To install the Windows 95/98/ME version, simply copy
the file A:\WIN95\PCI.EXE to your C:\WINDOWS
directory. To run the software, hit the RUN item on the
toolbar, type C:\WINDOWS\PCI.EXE when asked, and
then click RUN. A good UUT must be plugged into the
PCIEXT64U or UB and the “Slot Power” switch on the
PCIEXT64U or UB must be on before doing this.
Finding your UUT’s configuration registers
When PCI.EXE starts up, you will see a window with a
number of smaller windows in it. Open up this large
window as wide as possible, by dragging the lower right
corner of the large window. Each of the smaller
windows displays the first 16 configuration registers of a
PCI device. Hence, if there are 8 PCI devices in your
system, you will see eight small windows. Note that not
all of these PCI devices are plug-in boards - some are
motherboard PCI chips. One of these windows is the
configuration space for the UUT that is plugged into
your PCIEXT64U/UB. You will need to find out which
of these windows is the UUT’s. The first register in each
window (register 0) is the vendor ID number. Click on
each window until you see the one which shows the
vendor ID corresponding to your UUT. If you do not
know 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 window for your
UUT, this window should appear on top of other
windows. Open your UUT’s window to expose all
registers, by dragging its lower right corner downwards.
You will 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 want to save the
register contents, so that we can power off and remove
the UUT and then later restore these contents when
inserting a new UUT (of the same type).
To save the configuration register contents for your
UUT, and restore them on a new UUT, do the following:
1) Click on the “Cfg” button.
2) Click on “Read from NewBus”. This reads the current
register data from the UUT.
3) You may now turn off the slot power switch, remove
the UUT and replace it with a new UUT.
4) Then, turn the slot power on and restore the new
UUT’s configuration registers by clicking on “Cfg”
and “Write to NewBus”. Be sure you have not
accidentally clicked on a small window for a
different PCI device, or you may write to the
wrong board and crash the system!
5) Your new UUT should now be accessible to the
system in the same manner as the old one was.
6) You may test as many identical UUTs as you like,
without having to save the register contents each
time. Just turn off the slot power switch, plug in the
new UUT, turn on the slot power switch and click on
“Write to NewBus” to re-initialize each new 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 writable registers may be modified
by clicking on the desired field and typing in new
contents, and then clicking on “Write to NewBus”, to
send the modified data to the UUT.
Every time the system is re-booted, you must have
your UUT in the PCIEXT64U or UB and the slot
power switch turned on for correct live insertion
operation.

Installing and running PCINT.EXE under
Windows 2000
TM
or Windows XP
TM
To install the Windows XP/2000 version of live insertion
software, copy diskette files A:\WINNT\PCINT.EXE
and PCIEXT64.SYS to a directory that is in your path
statement, such as your C:\WINNT directory. If you
wish to run the software under the older Win NT OS,
copy the file PCIEXT64.OLD onto PCIEXT64.SYS,
However, this old version will not run under Win XP. To
run the software, 1) Be sure a good UUT is plugged into
the PCIEXTU, and 2) the “Slot Power” switch is on, and
then open a DOS window and type CD C:\WINNT and
then type PCINT. Or, alternatively, hit the RUN item on
the toolbar, and type C:\WINNT\PCINT.EXE when
asked what file to open. Then click RUN.
Finding your UUT’s configuration registers
When PCINT.EXE starts up, you will see a window
entitled “PCI Device List” with a list of PCI devices in it.
Hence, if there are 8 PCI devices in your system, you will
see eight items on the list. Not all of these PCI devices
are plug-in-boards - some are motherboard PCI chips.
One of these devices is the UUT that is plugged into
your PCIEXT64U or UB. You will need to find out
which 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 new window entitled “Edit PCI
Configuration Space” will appear which displays the first
16 configuration registers of that PCI device. The first
register in each window (register 0) is the vendor ID
number. Verify that the vendor ID you see is the
correct one for your UUT. If you do not know the
vendor ID of your UUT, ask the manufacturer of the
UUT. If the vendor ID you see does not match the one
known to be for your board, exit this window by clicking
on OK, and then get back to the list by clicking on File
and then clicking on Probe PCI List. Then select a
different board, and verify that it displays the vendor ID
known to be correct for your UUT.
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 we
can power off and remove the UUT and then later restore
these contents when inserting a new 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 window (entitled “Edit PCI
Configuration Space”) for your UUT, the contents you
see of the first 16 configuration registers of your
UUT have already been saved in a memory buffer,
and you can now turn off the slot power for your UUT,
remove the UUT and replace it with another UUT.
Then, turn the slot power on and restore the new
UUT’s registers by clicking on “Write to Device” and
then clicking “OK” in the Write Confirmation window.
Your new UUT should now be accessible to the system
in the same manner as the old one was.
You may test as many identical UUTs as you like without
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 and click on Write to Device and
then “OK” in the Write Confirmation menu, to initialize
each newly inserted device.
Saving the UUT configuration registers to a
file on disk (Optional)
Saving UUT configuration registers to disk is only
necessary if you will be exiting the PCINT.EXE program
before you swap 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” window,
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 which you had
originally stored your data. A device list should appear.
Click on the device name for your board. The “Edit
PCI Configuration Space” window will appear. Verify
that the Vendor ID is the correct one for your UUT
and then click on “Write to Device”. If you reboot
your system, do not restore configuration register
contents to a new UUT from the saved file, as the
registers are not always configured with 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 new

User Manual ~ UNIVERSAL PCI BUS EXTENDER Model PCIEXT64U and PCIEXT64UB
1/18/2007- REV F COPYRIGHT C 2007 ULTRAVIEW CORP. [phone] www.ultraviewcorp.com
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
writable registers may be modified by clicking on the
desired field, typing in new contents, and clicking on
“Write to Device”, to send the modified data to the UUT.
Every time the system is re-booted, you must have
your UUT in the PCIEXT64U /UB and the slot power
switch turned on for correct live insertion operation.
In Case of Trouble
The most common problems that are occasionally
encountered with live-insertion extenders are as follows:
1) System crashes/hangs when slot power turned on.
Some PCI boards do not come up with all of their PCI
bus lines tristated, as is required by the specification.
These boards may not work on live insertion extenders.
The PCIEXT64U or UB hold RESET low until at least
50 PCI clock cycles have been fed to the UUT. Then,
the PCIEXT64U or UB turns on its bus switches,
connecting the UUT (which should still be tristated) to
the motherboard’s PCI bus. Finally, the PCIEXT64U or
UB removes the RESET# signal to the UUT. This
allows correctly designed PCI bus boards to operate
properly on power-up on our live insertion extender.
If the system hangs or crashes when the slot power switch
is turned on, the board-under-test may be driving the bus
immediately after its power is brought up (while RESET#
is still asserted) which is illegal. One way to remedy the
problem is to redesign the board-under test.
2) System resets when slot power switch is turned on
The power supplies in some systems have inadequate
reserve capacity to handle the inrush current of some
boards-under-test when they are switched 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
slew-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
different 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 slew power
ramping on the PCIEXTU/UB.
