FEATURES
PCIBX is a Hot Swap PCI, PCI-X extender card, compliant with PCI 2.2 specification. This extender card is able to isolate
voltages and signals to the UUT for Hot Swapping purposes via software control or the on-board mechanical switch. The
software interface is done with the system parallel port in order to not add any additional loading on the PCI signals and to
be able to control the extender from a different system than the one testing the UUT.
All PCI signals are switched during On/Off operation, except the JTAG signals which are routed straight through without
any isolation.
The On-Off may be controlled via mechanical switch or the software. The power control domination between the switch and
software is explained here:
On power up ofthe extender card, the extender can be controlled by the mechanical switch in the case where
software control is not available. Once the first software instruction is issued, the mechanical switch is disabled,
and the control of the extender is passed tothe software.
In typical auto test applications it is suggested to leave the mechanical switch in the On position, so when the
system is powered up the BIOS can configure the PCI registers on the UUT. After the system has completed
booting user may issue SW commands (or continue to use the switch) to turn the power to the extender Off and
back On.
In addition to Hot Swapping the main voltages and signals, the PCIBX cards have the following features:
1) Short circuit protection
2) Software controllable +3.3Vaux.
3) Register to allow to reading of the status of the PME# signal.
4) On-board 3.3V source, 3 Amps
5) 5V ó3V signal translators for DUT óSystem, jumper selectable
6) I-to-V converters for +5V, +12V and +3.3V
7) ADC converter to read DUT voltages and currentmeasurement
8) Board select jumper for multiple boards operation, 2 boards per system.
9) Selectable RST#, fixed 150 ms or programmable reset width from 2.5 us to 5 seconds
10) Registers to read the status of the RST#, 66 MHz enable, 32 bit or 64 bit operation and status of the UUT
power
11) Frequency counter for measuring the slot clock speed
12) Selectable power up+5V ramp, 50 us or 10 ms
13) Detection of the DUT not being fully asserted in the extender. This detection works by detecting if both pins
B3 and B57 are connected to GND. If both signals are connected to GND it is assumed that the UUT is seated
correctly in the top connector.
14) PCI-X power up initialization. This feature allows the user to define how the PCI-X signal is handled by the
extender. Options are UUT determines, forced to 66 MHz PCI-X or disabled. These option are selected by the
position of JP17.

INTRODUCTION
PCIBX Active Extender board isolates 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.
This board also allows voltage margin testing of the UUT, by allowing external power supplies to replace the system power
supplies as inputs to the Unit-Under-Test.
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. On-board A/D also allows various current and voltage measurement via software
commands, see programming guide.
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.
OPERATION
In order to use the hot swap capability of these board you must use Catalyst software utility (PCIUD or PCIUW) available
our web site, http://www.getcatalyst.com,to read and write configuration registers. This software is available free of charge.
For an overview of these software packages see the Hot Swapping Utilities section of this manual.
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 system power is to stay On. There are two ways to turn the Active Extender power On and Off. 1) The mechanical
toggle switch. 2) Software control.
Note: Once the software control is used the mechanical switch becomes disabled until next power cycle tothe extender card.
The software control to the PCIBX boards is done via parallel port interface. Plug a parallel cable between the system port
running the software and the extender board(s) to turn the board(s) Onand Off. Up to 2 PCIBX boards in a system may be
controlled independently, if so desired.
POWER-ON RESET
Each time the Active Extender board is turned Off and then On, a reset signal will be generated from the extender to the
Unit-Under-Test automatically. The duration of this reset is about 150 milliseconds. This reset time may be changed by
software up to 5 seconds. The reset to the Unit-Under-Test is also generated every time there is a reset from the bus.

CURRENT MEASUREMENT
Measurement may be taken using software commands or external voltmeter.
Voltmeter: To measure the current being drawn by the Unit-Under-Test, just connect a voltmeter to J3. Every Volt read by
the meter represents one Amp. So if the voltmeter reads 0.35, it represents that the Unit-Under-Test is drawing 350
milliampere of current. J3 terminals are marked for Ground, +5I, +3.3I and +12I.
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, inorder to get an accurate current measurement for the +5V.
Software: The voltage and current to the UUT may also be measured by software, please see instructions in the
"Programming Guide".
CURRENT LIMIT CIRCUITRY
Red LEDs, when illuminated, indicate a short or a very low voltage. Green LEDs when illuminated, indicate voltages at their
corresponding outputs. +5V, +12V, +3.3Vare electronically protected. +VIO and-12V are protected by resetable fuses.
INCREASE CURRENT LIMIT
1-To increase the +5V currentlimit remove the resistor at location R23 and follow the steps below.
A: To change the current limit to 8 Amps install a 10K resistor at location R22 and 6.2K resistor at location R23.
B: To change the current limit to 10 Amps install a 10K resistor atlocation R22 and 10K resistor at location R23.
2-To increase the +3.3V current limit the system must be supplying the +3.3V and not the on board regulator.
A: To change the current limit to 8 Amps install a 4.7K resistor on top of existing R57.

EXTERNAL POWER SUPPLY
An external power input terminal, J5, is used 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 JP5. The list below identifies
which jumper is for which supply:
JP4 = -12V
JP5 = +5V
JP6 = +12V
JP7 = +3.3V
JP7 1-2 installed è3.3V from on-board regulator
JP7 2-3 installed è3.3V from the bus
JP7 not installedè3.3V from the external supply
The following diagram indicates the interconnection of the Unit-Under-Test voltages to the bus voltages and the external
voltages:
+5VE ON-OFF 5V out to UUT
Circuitry
VIO to UUT
JP5 JP10
ON-OFF
Circuitry
+5V from the bus +VIO from bus
As indicated, there will be 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 between the system and the
supply. 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 phase/level with respect to a common point, before
connecting the GND signal.
If making current measurements in +5V, be sure to remove JP10 if the VIO and +5V on your
board are on the same voltage plane.

LEDs
There are two sets of LED on the board, green and red. Each LED has a label which Voltage it represents. The green LED,
when lit, indicates presence ofthe corresponding voltage. The red LED, when lit, represent a short on the corresponding
voltage at the output. Please note that the green LEDsindicate presence of some voltage and do not necessarily indicate if
the exact voltage is at the expected level.
LED Purpose of LED
D10 -12V is present
D11 +12V is present
D12 +5V is present
D13 +3.3V is present
D18 +VIO is present
D9 -12V has a short or low voltage condition
D15 +12V has a short or low voltage condition
D14 +3.3V has a short or low voltage condition
D16 +5V has a short or low voltage condition
5V ó3.3 V Translation
PCIBX is capable of allowing 5V UUT to work with 3.3V system and vice versa, without any timing degridation. Therefore
cards or components needing 3.3 V signaling can be tested or operated on a 5-volt system using these extender cards.
+5V cards can operate in +3.3V systems provided that +5V is provided to the UUT cards.
If JP3 is installed the UUT signals will be the same as the bus signals, most likely +5V.
If JP3 is not installed the signalsbetween the bus and the UUT will be translated.
