INTRODUCTION
These Active Extender boards allow HOT SWAPPING or LIVE INSERTION of the Unit-Under-Test into
PCI (CompactPCI for CPCI-64) bus. 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 Unit-Under-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 (known as “Quick Switch”) for switching the signals
On and Off. These switches have feature a very low 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, falls to +3.0V. During the power up the signals stay isolated until the
main voltage is at least +3.0V.
CPCI-64 and PCIAX Rev B and higher extender boards also allow 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 a voltmeter attached 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 its 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.

OPERATION
Using these Active Extender boards is no different than using a regular extender board, except that the
Active Extenders boards offer several extra features. These are explained below:
ON-OFF
To insert or remove a Unit-Under-Test while system power is on, make sure that the Active Extender is
turned Off. There are two ways to turn the Active Extender power On and Off. 1) The mechanical toggle
switch on the card. 2) The external control signal.
PCIAX
PCIAX boards may be controlled via a parallel port interface. Turn the On-Off switch to the Off position,
plug a parallel cable between the system port and the board(s) and use the system parallel port address to
turn the board(s) On and Off.
Several PCIAX Rev B (and higher) boards in the same system may be controlled independently, if so
desired. Jumper J6 on the board may be used to configure each board to be turned On and Off by a
different bit of the parallel port. For example, board One may be set to be controlled by D0 and board Two
may be set to be controlled by D1. A Low level for each bit will turn the board On and High will turn the
board Off

Assuming the system parallel port address is set at 378:

In order to control the PCIAX using software command:
outp (0x378, 0xFF) Will turn all boards Off
outp (0x378, 0x80) Will turn only board one On
outp (0x378, 0x81) Will turn only board two On
CPCI-64
The external control input for the CPCI is at JPX. Top signal is a Ground signal and the bottom signal is
the control signal. To control On-Off by the external signal, you must have the mechanical switch in the
Off position. A Low level, less than 1.5V, will turn the board ON.
supports Global Address signals (GA0 – GA4).
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 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 hang-up. It may be a good practice to stop the software from
running, before isolating the power and the signals to the Unit-Under-Test.
