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.

4

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.)

PMC BUS MODE SIGNALS

The 4 bus mode signals for the PMC bus are selectable on the PMC2PCI-64 extender board. These signals
BUSMODE1, BUSMODE2, BUSMODE3 and BUSMODE4 are connected to 3 push-on jumpers JPN2, JPN3
and JPN4 respectively. These jumpers are pulled up to VCC with a 10K resistor each. If the jumper is not in
place the signal will go HI, and if the jumper is in place the signal will be grounded and represents a LOW.

BUSMODE1 is an output signal, represented by an LED which indicates when this output is low, asserted.
When the PMC card asserts this output the LED will illuminate.

For the PMC2PCI-64, the signals PRSNT1# and PRSNT2# on the PCI bus side of the extender board,
are hard wired to represent 25 Watts of power requirement, PRSNT1# = GND and PRSNT2# = OPEN.

EXTERNAL POWER SUPPLY

On the PCI532/332 the terminal VINEX is used and J6 terminal is used on other cards for the external power
supply input. However remember never to connect any supply to these inputs so long as you have JP4, JP5,
JP6 and JP7 installed.

In case you want to use the external supply as an input you must remove these 4 jumpers in order not to cause
any conflict with the bus voltages. These jumpers are, however, independent from each other.

For instance if you would want to bring in only a +5V from the external supply and continue to use the bus
voltages for +12V, -12V, and +3.3V, you would only need to remove JP6. The list below identifies which
jumper is for which supply:

JP4 = +12V, Next to Q5 pin 3 (left side of the board).
JP5 = -12V, Next to Q7 pin 3 (left side of the board).
JP6 = +5V, Next to Q6 pin 3, also JP10 for +VIO, if connected to +5V on your board.
JP7 = +3.3V, Next to Q9 pin 3.

The following diagram indicates the interconnection of the Unit-Under-Test voltages to bus voltages and the
external voltages:

+5VE to Unit-Under-Test

ON-OFF
Circuitry +5BV

+VIOB

JP6

+5V from the Bus ON-OFF
Circuitry

+VIO from bus (+5v plane)

As you can see, there will be a conflict in case the external supply is connected while the jumper is still in
place. This circuit is repeated for each of the 4 voltages.

If you are using external power supplies do not forget to connect the Ground (GND) signals. If your external
power supply outputs are not isolated, make sure the ground of the PC (containing the extender board) and the
ground of the power supply are at the same voltage level with respect to a common point, before connecting
the GND signal.

Note: Be sure to remove JP10 if the VIO and +5V on your board are on the same voltage plane.

PCI HOT SWAP UTILITIES

The purpose of the utilities is to provide the user with the knowledge and application of Hot Swap utility software
and extender cards for purposes of swapping PCI cards while the system power stays on. These utilities will allow
the user to perform various functions with the Catalyst Enterprises, PCI Active extenders. The software allows the
user to read, save and reload the configuration space data and allow the user to control the power of to the UUT
during testing via the test program. For more information see the Hot Swapping PCI Cards document, located on
our web site http://www.catalyst-ent.com under the documents page.

5V=>3V TRANSITION

The PCIX6432/PCIX6466-3 and PMC2PCI-64 Active Extender cards are capable of translating the incoming
5-volt signals to 3.3 volts for the UUT without any timing degradation. Therefore cards or components
needing 3-volt environment can be tested or operated on a 5-volt system using these extender cards.

If JP9 (PCIX6432/PCIX6466-3) or JPX (PMC2PCI-64) is installed the UUT signals will be the same as the
bus signals, most likely 5V. If not installed the signals to the UUT will be translated down to 3.3V.

To use this feature with the PCI532, performing the follow reworks:

• Remove R32

• Install a 191 Ohm resistor at R32

3.3V INPUT

The PCIX6432/PCIX6466-3 Active Extender cards have an on-board 3.3 volt regulator (PCIX6432 Rev C and
higher).

JP7 selects the source of the 3.3V to the UUT.
JP7 1-2 3.3V from the on-board regulator.

JP7 2-3 3.3V from the system bus.

JP7 no shunts 3.3V from the external supply.

AUXILIARY POWER CONNECTOR PIN-OUT

PCI532 and PCI332 power connector for the external power supply is different than the one used for
PMC2PCI and PCIX-6432. The PCI532 connector is marked as indicated, but the other connectors are
intended for use with ribbon cable and are not marked on the board. The following pin-out can be used if the
user wants to arrange his own interface. Please note that each signals is divided and placed symmetrically on
both sides of the connector, this will allow the connector to be plugged in either direction and make proper
connection.

The EV signals are the voltage signals, remember not to bring in any external voltages until you reconfigure
the jumpers for external supply mode. The VS signals are sense signals for compensating any voltage lose in
the cable. The SW is an open collector signal and it is the sane as the switch or jumper JP3 to turn the board
on and off.
