Safety Precautions

The following safety precautions should be observed before using
this product and any associated instrumentation. Although some in­struments and accessories would normally be used with non-haz­ardous voltages, there are situations where hazardous conditions
may be present.

This product is intended for use by qualified personnel who recog­nize shock hazards and are familiar with the safety precautions re­quired to avoid possible injury. Read and follow all installation,
operation, and maintenance information carefully before using the
product. Refer to the manual for complete product specifications.

If the product is used in a manner not specified, the protection pro­vided by the product may be impaired.

The types of product users are:

Responsible body is the individual or group responsible for the use

and maintenance of equipment, for ensuring that the equipment is
operated within its specifications and operating limits, and for en­suring that operators are adequately trained.

Operators use the product for its intended function. They must be

trained in electrical safety procedures and proper use of the instru­ment. They must be protected from electric shock and contact with
hazardous live circuits.

Maintenance personnel perform routine procedures on the product

to keep it operating properly, for example, setting the line voltage
or replacing consumable materials. Maintenance procedures are de­scribed in the manual. The procedures explicitly state if the operator
may perform them. Otherwise, they should be performed only by
service personnel.

Service personnel are trained to work on live circuits, and perform

safe installations and repairs of products. Only properly trained ser­vice personnel may perform installation and service procedures.

Keithley products are designed for use with electrical signals that
are rated Installation Category I and Installation Category II, as de­scribed in the International Electrotechnical Commission (IEC)
Standard IEC 60664. Most measurement, control, and data I/O sig­nals are Installation Category I and must not be directly connected
to mains voltage or to voltage sources with high transient over-volt­ages. Installation Category II connections require protection for
high transient over-voltages often associated with local AC mains
connections. Assume all measurement, control, and data I/O con­nections are for connection to Category I sources unless otherwise
marked or described in the Manual.

Exercise extreme caution when a shock hazard is present. Lethal
voltage may be present on cable connector jacks or test fixtures. The
American National Standards Institute (ANSI) states that a shock
hazard exists when voltage levels greater than 30V RMS, 42.4V
peak, or 60VDC are present. A good safety practice is to expect

that hazardous voltage is present in any unknown circuit before
measuring.

Operators of this product must be protected from electric shock at
all times. The responsible body must ensure that operators are pre­vented access and/or insulated from every connection point. In
some cases, connections must be exposed to potential human con­tact. Product operators in these circumstances must be trained to
protect themselves from the risk of electric shock. If the circuit is
capable of operating at or above 1000 volts, no conductive part of

the circuit may be exposed.

Do not connect switching cards directly to unlimited power circuits.
They are intended to be used with impedance limited sources.
NEVER connect switching cards directly to AC mains. When con­necting sources to switching cards, install protective devices to lim­it fault current and voltage to the card.

Before operating an instrument, make sure the line cord is connect­ed to a properly grounded power receptacle. Inspect the connecting
cables, test leads, and jumpers for possible wear, cracks, or breaks
before each use.

When installing equipment where access to the main power cord is
restricted, such as rack mounting, a separate main input power dis­connect device must be provided, in close proximity to the equip­ment and within easy reach of the operator.

For maximum safety, do not touch the product, test cables, or any
other instruments while power is applied to the circuit under test.
ALWAYS remove power from the entire test system and discharge
any capacitors before: connecting or disconnecting cables or jump­ers, installing or removing switching cards, or making internal
changes, such as installing or removing jumpers.

Do not touch any object that could provide a current path to the com­mon side of the circuit under test or power line (earth) ground. Always
make measurements with dry hands while standing on a dry, insulated
surface capable of withstanding the voltage being measured.

The instrument and accessories must be used in accordance with its
specifications and operating instructions or the safety of the equip­ment may be impaired.

Do not exceed the maximum signal levels of the instruments and ac­cessories, as defined in the specifications and operating informa­tion, and as shown on the instrument or test fixture panels, or
switching card.

When fuses are used in a product, replace with same type and rating
for continued protection against fire hazard.

Chassis connections must only be used as shield connections for
measuring circuits, NOT as safety earth ground connections.

If you are using a test fixture, keep the lid closed while power is ap­plied to the device under test. Safe operation requires the use of a
lid interlock.

5/02

If or is present, connect it to safety earth ground using the
wire recommended in the user documentation.

!

The symbol on an instrument indicates that the user should re­fer to the operating instructions located in the manual.

The symbol on an instrument shows that it can source or mea­sure 1000 volts or more, including the combined effect of normal
and common mode voltages. Use standard safety precautions to
avoid personal contact with these voltages.

The WARNING heading in a manual explains dangers that might
result in personal injury or death. Always read the associated infor­mation very carefully before performing the indicated procedure.

The CAUTION heading in a manual explains hazards that could
damage the instrument. Such damage may invalidate the warranty.

Instrumentation and accessories shall not be connected to humans.

Before performing any maintenance, disconnect the line cord and
all test cables.

To maintain protection from electric shock and fire, replacement
components in mains circuits, including the power transformer, test
leads, and input jacks, must be purchased from Keithley Instru­ments. Standard fuses, with applicable national safety approvals,
may be used if the rating and type are the same. Other components
that are not safety related may be purchased from other suppliers as
long as they are equivalent to the original component. (Note that se­lected parts should be purchased only through Keithley Instruments
to maintain accuracy and functionality of the product.) If you are
unsure about the applicability of a replacement component, call a
Keithley Instruments office for information.

To clean an instrument, use a damp cloth or mild, water based
cleaner. Clean the exterior of the instrument only. Do not apply
cleaner directly to the instrument or allow liquids to enter or spill
on the instrument. Products that consist of a circuit board with no
case or chassis (e.g., data acquisition board for installation into a
computer) should never require cleaning if handled according to in­structions. If the board becomes contaminated and operation is af­fected, the board should be returned to the factory for proper
cleaning/servicing.

Functional description

The KPCI-PIO32IOA and KPCI-PDISO8A each contain isolated control inputs and isolated
solid-state relay switching outputs on a PCI interface board. Both cards work in a Windows
environment and take advantage of the 32-bit bus width.

Pentium or higher processor on motherboard with PCI bus version 2.1.

Windows® 95, 98, or Me.

Windows® NT (version 4.0 or higher), 2000, or XP.

16 MB or greater RAM when running Windows® 95, 98, or Me.

32 MB or greater RAM when running Windows® NT, 2000, or XP.

4 MB for minimum installation.

50 MB for maximum installation.

A CD-ROM drive*.

A free PCI bus expansion slot.

Enough reserve computer power supply capacity to power the board,
which draws 500mA from the 5V supply (maximum).

Solid-state relay switching

The KPCI-PIO32IOA’s 32 isolated I/O lines and KPCI-PDISO8A’s 16 isolated I/O lines include:

Control inputs are solid-state, opto-isolated (16 for the KPCI-PIO32IOA; 8 for the
KPCI-PDISO8A). Maximum control input voltages are: ±60V DC (logic high); ±1V DC
(logic low).

Relay outputs are solid-state, opto-isolated, N.O. form A (16 for the KPCI-PIO32IOA; 8 for
the KPCI-PDISO8A). Outputs can switch both DC voltages (±60V DC maximum) and AC
voltages (30V RMS maximum) with a maximum load current of 350mA. A relay output will
close when a logic high is applied to the corresponding control input.

KPCI-PIO32IOA and KPCI-PDISO8A User’s Manual General Description 2-3

Under Windows 98/Me, most existing port I/O application programs and data acquisition pack­ages designed for ISA boards work with the KPCI-PIO32IOA and KPCI-PDISO8A board. The
PCI-BIOS-assigned base address is entered in place of a user-assigned base address. (Use of
such programs under Windows NT/2000/XP, not recommended, is much more involved.)

Other I/O characteristics

Additional I/O port characteristics are summarized below:

Two of the KPCI-PIO32IOA and KPCI-PDISO8A general-purpose I/O lines can be alterna­tively configured via software to be external interrupt enable input, INT_ENN, and external
interrupt request input, INT_REQ.

The KPCI-PIO32IOA and KPCI-PDISO8A can switch currents up to 350mA. Output cur­rent capabilities allow the boards to control some motors, solenoids, and relays.

+5V power from the computer power supply is made available at the I/O connector, for use
in external circuits.

Software

NOTE

Control inputs and relay outputs interface via standard 36-pin connector(s). The
KPCI-PIO32IOA has two 36-pin connectors, and the KPCI-PDISO8A has one 36-pin
connector.

Output ports can always be read-accessed without switching the output states, allowing the
output states to be read at any time by the controlling program.

The user can select a fully integrated data acquisition software package (e.g., TestPoint or
LabVIEW) or write a custom program supported by DriverLINX. DriverLINX software is
included with the hardware.

DriverLINX supports programmers who wish to create custom applications using Visual C/C++,
Visual Basic, or Delphi. DriverLINX accomplishes foreground and background tasks to perform
data acquisition. TestPoint is a fully featured, integrated application package with a graphical
drag-and-drop interface, which can be used to create data acquisition applications without pro­gramming. LabVIEW is a fully featured graphical programming language used to create virtual
instrumentation.

Refer to Section 3, “Installation,” for more information about software.

The maximum current on each +5V and digital ground pin is 1A. The
+5V supply is not isolated and is available for use only when isolation is
not required by the application.

The KPCI-PIO32IOA and KPCI-PDISO8A boards have two software options. The user can
select a fully integrated data acquisition software package (e.g., TestPoint or LabVIEW). The
user can also run a custom program in Visual C/C++, Visual Basic, or Delphi using DriverLINX
(included with the hardware). A summary of the pros and cons of using integrated packages or
writing custom programs is provided in the Keithley Full Line Catalog. The KPCI-PIO32IOA
and KPCI-PDISO8A have fully functional driver support for use under Windows.

NOTE

DriverLINX driver software for Windows

DriverLINX software, supplied by Keithley with the KPCI-PIO32IOA and KPCI-PDISO8A
board, provides convenient interfaces to configure and set I/O bits without register-level pro­gramming. DriverLINX supports Windows 98, Me, NT, 2000, and XP.

Install the DriverLINX software before installing the KPCI-PIO32IOA
or KPCI-PDISO8A board. Otherwise, the device drivers will be more
difficult to install.

DriverLINX must be installed to run any applications for the board,
whether they are custom-programmed applications or integrated soft­ware packages, such as TestPoint or LabVIEW.

Most importantly, however, DriverLINX supports those programmers who wish to create cus­tom applications using Visual C/C++, Visual Basic, or Delphi. DriverLINX accomplishes fore­ground and background tasks to perform data acquisition. The software includes memory and
data buffer management, event triggering, extensive error checking, and context sensitive online
help.

More specifically, DriverLINX provides application developers a standardized interface to over
100 services for creating foreground and background tasks for the following:

Analog input and output

Digital input and output

Time and frequency measurement

Event counting

Pulse output

Period measurement

•

uilt-in capabilities to handle memory and data buffer management.

A selection of starting and stopping trigger events, including pre-triggering, mid-point trig­gering, and post-triggering protocols.

Extensive error checking.

Context-sensitive on-line help system.

Refer to your DriverLINX documentation to determine which services are supported by your
KPCI-PIO32IOA or KPCI-PDISO8A board.

DriverLINX applications can be independent of some differences in data acquisitions boards
because its portable APIs work across various operating systems. This capability eliminates
unnecessary programming when changing operating system platforms.

TestPoint

TestPoint is a fully featured, integrated application package that incorporates many commonly
used math, analysis, report generation, and graphics functions. TestPoint’s graphical
drag-and-drop interface can be used to create data acquisition applications for IEEE-488 instru­ments, data acquisition boards, and RS232-485 instruments and devices.

TestPoint includes features for controlling external devices, responding to events, processing
data, creating report files, and exchanging information with other Windows programs. It pro­vides libraries for controlling most popular GPIB instruments. OCX and ActiveX controls plug
directly into TestPoint, allowing additional features from third party suppliers.

LabVIEW

LabVIEW is a fully featured graphical programming language used to create virtual instrumen­tation. It consists of an interactive user interface, complete with knobs, slides, switches, graphs,
strip charts, and other instrument panel controls. Its data driven environment uses function
blocks that are virtually wired together and pass data to each other. The function blocks, which
are selected from palette menus, range from arithmetic functions to advanced acquisition, con­trol, and analysis routines. Also included are debugging tools, help windows, execution high­lighting, single stepping, probes, and breakpoints to trace and monitor the data flow execution.
LabVIEW can be used to create professional applications with minimal programming.

Virtual instruments (VIs) compatible with LabVIEW are available for the KPCI-PIO32IOA and
KPCI-PDISO8A.

Installing DriverLINX

Refer to the Read this first document that accompanies your board for installation instructions.

NOTE

Always install DriverLINX before installing the board or LabVIEW sup­port. Both TestPoint and LabVIEW support require DriverLINX to
access the board’s hardware resources.

Installing application software and drivers

Installing the TestPoint support

TestPoint provides an object for control of digital I/O channels based on the DriverLINX driver.
In the directory where TestPoint is installed (C:\TESTPT), find and open DLDIO.TST. The
DLINX.DIO object from this example can be copied and pasted into your custom application.

Check with the following concerning driver updates with TestPoint support for the
KPCI-PIO32IOA and KPCI-PDISO8A:

The TestPoint technical support page of the Keithley web site (www.keithley.com).

The TestPoint manufacturer, Capital Equipment Corporation (CEC).

Installing the LabVIEW software and driver

If you plan to use only run-time LabVIEW applications with your KPCI-PIO32IOA or
KPCI-PDISO8A board, you need not install DriverLINX’s LabVIEW support package.
LabVIEW run-time support is automatically installed when you install and configure
DriverLINX.

However, if you plan to develop custom applications using the LabVIEW Integrated
Development Environment, you must install the DriverLINX Virtual Instruments (VIs). These
VIs are provided on your DriverLINX CD-ROM but do not install automatically when you
install DriverLINX and your board. You must first install the LabVIEW application program and
DriverLINX, then install the DriverLINX VIs.

If you do not install the VIs during the same session in which you install DriverLINX (refer to
your Read this first document), you may install them later as follows:

1. Start setup.exe on the DriverLINX CD-ROM. The DriverLINX Browser introduction screen
appears.

2. Click Next on the DriverLINX Browser introduction screen (or wait a few seconds). The
DriverLINX CD Navigator screen appears.

3. On the DriverLINX CD Navigator screen, click Install DriverLINX . An Install These
DriverLINX Components screen appears.

4. On the Install These DriverLINX Components screen, click LabVIEW™ Support .

5. Follow the series of on-screen instructions that appear.

Installing the KPCI-PIO32IOA and KPCI-PDISO8A boards

This subsection helps you to do the following:

Prepare for the board installation.

Physically install the board.

WARNING Turn off the computer power and disconnect all external circuits

from the board to avoid a possible shock hazard.

CAUTION Handle the board in a static-controlled workstation; wear a

grounded wrist strap. Discharge static voltage differences between
the wrapped board and the handling environment before removing
the board from its protective wrapper. Failure to discharge static
electricity before and during handling may damage semiconductor
circuits on the board.

Handle the board using the mounting bracket. Do not touch the cir­cuit traces or connector contacts when handling the board.

KPCI-PIO32IOA and KPCI-PDISO8A User’s Manual Installation 3-5

Checking resources for the board

Ensure that your computer has sufficient resources, particularly power resources, to run your
KPCI-PIO32IOA or KPCI-PDISO8A board. Check the capacity of the computer power supply
and the power requirements of your computer and presently installed boards. Then check the
additional power requirements for this board. (Refer to Appendix A, “Specifications.”) If neces­sary, free resources by uninstalling other boards.

System responsibility

The system integrator has final responsibility for the EMC of a system containing Keithley
KPCI-PIO32IOA and KPCI-PDISO8A boards. The user must not assume that installation of the
CE-marked KPCI-PIO32IOA or KPCI-PDISO8A in a CE-marked PC will result in a system
with acceptable RFI emissions.

Unwrapping and inspecting the board

NOTE

After you remove the wrapped board from its outer shipping carton, unwrap and inspect it as
follows:

1. Your board is packaged at the factory in an anti-static wrapper. Do not remove the anti-static
wrapper until you have discharged any static electricity voltage differences between the
wrapped board and the environment. Wear a grounded wrist strap. A grounded wrist strap
discharges static electricity from the wrapped board as soon as you hold it. Keep the wrist
strap on until you have finished installing the board.

2. Remove the board from its anti-static wrapping material. (Store the wrapping material for
future use.)

3. Inspect the board for damage. If damage is apparent, arrange to return the board to the fac­tory. Refer to Section 5, “Troubleshooting.”

4. Check the remaining contents of your package against the packing list and immediately
report any missing items.

5. If the inspection is satisfactory, proceed to “Installing the board.”

Install the DriverLINX software before installing the KPCI-PIO32IOA
or KPCI-PDISO8A board. Otherwise, the device drivers will be more
difficult to install.

Installing the board

Install a board in a PCI expansion slot on your computer as follows:

1. Turn power OFF to the computer and to any external circuits attached to the board.

2. Remove the computer chassis cover.

3. Select an unoccupied PCI expansion slot in the rear panel, and remove the corresponding
dummy mounting plate.

4. Insert the PCI connector of the board into the selected PCI slot of the computer. Take care
not to interfere with neighboring boards. Ensure that the board is properly seated in the slot.

5. Secure the mounting bracket of the board to the chassis, using the retaining screw that you
removed when you removed the dummy mounting plate.

6. Continue with the next subsection, “Configuring and checking the board and DriverLINX

installations.”
