INTRODUCTION
These PCI Active Extender boards allow HOT SWAPPING or LIVE INSERTION of Unit-Under-Test into
PCI bus. The PCI extender series supports the entire range of the PCI bus (32-bit, 64-bit, 3.3V, 5V, 66 Mhz
and even PCI Mezzanine). The “HOT SWAPPING” feature of these extenders eliminates the need for turning
the PC Off and On and repeated rebooting. This feature speeds up rework, characterization and test of UnitUnder-Test in the development phase as well as production test. The elimination of the repeated power cycling
also helps prolong the system life and the hard disc operation. These Active Extenders use a new CMOS
technology for switching the signals On and Off (known as "Quick Switch"). These switches have a very fast
propagation delay, typically about 250 picoseconds, resulting in no timing degradation between the bus and
the Unit- Under-Test. The switches are also bidirectional allowing the entire address range to be supported for
both target and master type operation.
These Active Extender boards isolate all signals and voltages to the Unit-Under-Test, when the On-Off switch
is in the Off position. All voltages are ramped down and ramped up during the power down and power up in
order to eliminate any spikes. During the power down the signals to the bus become isolated as soon as the
main supply, +5V, reaches down to +3.0V. During the power up the signals stay isolated until the main
voltage is at least +3.0V.
These Active Extenders also allow for voltage margin testing of the Unit-Under-Test by allowing external
power supplies to replace the bus supplies as inputs to the Unit-Under-Test.
An on-board current-to-voltage converters allow measurement of the current drawn by the UUT at any time,
using just a voltmeter at the appropriate test points.
INSTALLATION
To install the Active Extender board, make sure to turn the PC power off. Insert the Active Extender in any
available slot and secure it's bracket to the main chassis. You are now ready to use your new extender board.
NOTE: If you are planning to use an external I/O signal to control the board, the On-Off switch must
be in the Off position and the dip switch must be in the CLOSED (ON) position.

OPERATION
ON-OFF
To insert or remove any Unit-Under-Test into and out of the Active Extender, make sure that the Active
Extender is turned Off, if the PC power is to stay On. There are two ways to turn the Active Extender power
On and Off. 1) The mechanical toggle switch. 2) External control signal connected to JP3.
External control can be used if remote controlling is desired for turning the power On and Off. Leave the
mechanical switch in the Off position, then use a CMOS or TTL level signal to control turning the power On
via JP3. The left connector of JP3 is ground and the right connector is the control signal. A Low level, less
than 1.5V , will turn the switch ON.
Software control is also possible using the external control with a custom interfacing between the parallel port
and the board. Consult the factory if you need additional help for implementing this feature.
NOTE: During the power Off, all signals become isolated between the bus and the Unit-Under-Test when the
+5V to the Unit-Under-Test becomes less than 3.0V.
NOTE: If you are running a software that relies on a response from the Unit-Under-Test, do not turn off the
Active Extender board unless the handshaking has taken place, Otherwise you may experience a system hangup. It may be a good practice to stop the software from running, before isolating the power and the signals to
the Unit-Under-Test.
POWER-ON RESET
Each time the Active Extender board is turned Off and then On, reset signal will be generated from the
extender to the Unit-Under-Test automatically. The duration of this reset is 200 milliseconds. The reset to the
Unit-Under-Test is also activated every time there is a reset from the bus.
BANK SWITCHES
In a normal operation, the bank switches should be left in the closed position. In this case when the power to
the extender is turned on, all of the bus signals will be active to and from the Unit-Under-Test. However,
when there is a problem with the signals from the Unit-Under-Test, the signals can be activated in a smaller
group.
NOTE: The bank switch number 1 controls U1, bank switch 2 controls U2, ... , and the final bank
switch 8 controls U8. For 64 bit extenders, switch 9 controls the ICs U12 and U13 (all 64 bit
signals on the B side) and switch 10 controls ICs U14 and U15 (all 64 bit signals on the A side).
For the signal names and grouping by the U number see the section on the auxiliary pinout.

CURRENT MEASUREMENT
When using the PCI532, the user can measure the +5V current being drawn by the Unit-Under-Test, by just
connecting a voltmeter to J3.
When using the PMC2PCI and PCIX6432 (Rev. C and below), the user can measure the +5V current being
drawn by the UUT using a voltmeter at J3, the current draw for the +12V can be measured by using a voltage
meter at J4 and the current draw for the +3.3V can be measured using voltmeter at J5.
When using the PCIX6432 (Rev. D or higher), the user can measure the current draw on the +5V using a
voltmeter between J3.1 and J3.2. To measure the current draw on the +3.3V measure using a voltmeter
between J3.1 and J3.3, and the measure the current draw on the +12V, measure using a voltmeter between
J3.1 and J3.4.
Every Volt read by the meter represents One Amp. So if the voltmeter reads 0.35, it represents that the UnitUnder-Test is drawing 350 milliamps of current from +5V supply.
NOTE: If the VIO and +5V are on the same plane on your board, you need to remove JP10 jumper, located
on the extender board, in order to get an accurate current measurement.
CURRENT LIMIT CIRCUITRY
Red LEDs, when illuminated, indicate a short or a very low voltage at the output for their corresponding
voltages. Green LEDs when illuminated, indicate voltages at their corresponding outputs. In the case of the
+5V short from the Unit-Under-Test, the Active Extender will automatically switch the current limit down to
about 200 milliamps and will continue to deliver this current for troubleshooting purposes. On the PCIX-6432
and PMC2PCI boards this feature is extended to cover the +12V and +3.3V as well. In the case of shorts or
excessive current draw for the other voltages the resetable fuses will open up until the problem is corrected.
The current limit value for the +5V is set to 5 Amps with JP8 not installed and 1 Amp with JP8 installed.
CURRENT LIMIT ADJUSTMENTS
FOR PCI532/PCI332
To increase the +5v current limit you must reduce the gain of the current measurement circuitry.
Perform the following reworks:
• To change the current limit to 7.5A install a 200k Resistor on top of R19 and R22, this will cause
the current measurement circuit gain to be reduced by a factor 0.66 (I.e. 1 volt will represent 1.5
A current draw.)
• To change the current limit to 10A install a 100k Resistor on top of R19 and R22, this will cause
the current measurement circuit gain to be reduced by a factor 0.50 (I.e. 1 volt will represent 2 A
current draw.)
To increase the +3.3v current limit you must place an additional fuse across F4 which will increase
the current limit to 2A.

FOR PCIX6432/PCIX6466-3 (Rev. C and below)
To increase the +5v current limit you must cut the trace between the pads of R23 and perform the
following reworks:
• To change the current limit to 8A install a 10k resistor at location R22 and a 6.2k resistor at location
R23. This does not affect the current measurement reading.
• To change the current limit to 10A install a 10k resistor at location R22 and R23. This does not
affect the current measurement reading.
To increase the +3.3v current limit must supply the +3.3v from the mother board or an external power
supply, and reduce the gain of the current measurement circuitry. Perform the following rework:
• To change the current limit to 5A install a 100k Resistor on top of R33 and R34, this will cause the
current measurement circuit gain to be reduced by a factor 0.50 (I.e. 1 volt will represent 2 A current
draw.)
FOR PCIX6432/PCIX6466-3 (Rev. D and above)
To increase the +5v current limit you must remove R23 and perform the following reworks:
• To change the current limit to 8A install a 10k resistor at location R22 and a 6.2k resistor at location
R23. This does not affect the current measurement reading.
• To change the current limit to 10A install a 10k resistor at location R22 and R23. This does not
affect the current measurement reading.
To increase the +3.3v current limit must supply the +3.3v from the mother board or an external power
supply, and reduce the gain of the current measurement circuitry. Perform the following rework:
• To change the current limit to 5A remove resistor installed at R60, install a 40K resistor, This
does not affect the current measurement reading.
FOR PMC2PCI-64
To increase the +5v current limit you must remove the resistor at R29 and perform the following
reworks:
• To change the current limit to 8A install a 10k resistor at location R30 and a 6.2k resistor at location
R29. This does not affect the current measurement reading.
• To change the current limit to 10A install a 10k resistor at location R30 and R29. This does not
affect the current measurement reading.
To increase the +3.3v current limit you must supply the +3.3v from the mother board or an external
power supply, and reduce the gain of the current measurement circuitry. Perform the following reworks:
• To change the current limit to 5A install a 100k Resistor on top of R39 and R38, this will cause the
current measurement circuit gain to be reduced by a factor 0.50 (I.e. 1 volt will represent 2 A current
draw.)
