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 to the 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) On and 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.
