Safety Precautions
The following safety precautions should be observed before using
this product and any associated instrumentation. Although some in-
struments and accessories would normally be used with non-haz-
ardous voltages, there are situations where hazardous conditions
may be present.
This product is intended for use by qualified personnel who recog-
nize shock hazards and are familiar with the safety precautions re-
quired 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 pro-
vided 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 en-
suring 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 instru-
ment. 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 de-
scribed 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 ser-
vice 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 de-
scribed in the International Electrotechnical Commission (IEC)
Standard IEC 60664. Most measurement, control, and data I/O sig-
nals are Installation Category I and must not be directly connected
to mains voltage or to voltage sources with high transient over-volt-
ages. 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 con-
nections 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 pre-
vented access and/or insulated from every connection point. In
some cases, connections must be exposed to potential human con-
tact. 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 con-
necting sources to switching cards, install protective devices to lim-
it fault current and voltage to the card.
Before operating an instrument, make sure the line cord is connect-
ed 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 dis-
connect device must be provided, in close proximity to the equip-
ment 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 jump-
ers, 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 com-
mon 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 equip-
ment may be impaired.
Do not exceed the maximum signal levels of the instruments and ac-
cessories, as defined in the specifications and operating informa-
tion, 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 ap-
plied to the device under test. Safe operation requires the use of a
lid interlock.

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

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 re-
fer to the operating instructions located in the manual.
The symbol on an instrument shows that it can source or mea-
sure 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 infor-
mation 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 Instru-
ments. 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 se-
lected 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 in-
structions. If the board becomes contaminated and operation is af-
fected, the board should be returned to the factory for proper
cleaning/servicing.

KPCI-3160 works in a Windows 95/98/NT environment and takes advantage of the 32-bit width.
Applications include communicating with peripherals, operating Keithley relay boards, and
reading switch inputs. All I/O lines are TTL compatible.
Standard digital I/O emulation
The 96 I/O lines emulate the I/O lines of four Intel 8255 Programmable Peripheral Interface
(PPI) chips configured for control register mode 0, as follows:
• For each emulated 8255 chip there is a PA port, a PB port, and a PC port.
• Each PA and PB port is byte-wide (8-bits) and can be set independently under software con-
trol as inputs or outputs.

KPCI-3160 User’s Manual General Description 2-3
• Each PC port is byte-wide but can be divided into two separate 4-bit ports: PC lower and PC
upper, each of which can be set up as either inputs or outputs.
Under Windows 95/98, most existing port I/O application programs and data acquisition pack-
ages designed for ISA boards work with the KPCI-3160 board. The PCI-BIOS-assigned base
address is entered in place of a user-assigned base address. (Use of such programs under
Windows NT, not recommended, is much more involved.) Refer to “Using existing port I/O soft-
ware to manipulate control and data registers,” Appendix B.
Other I/O characteristics
Additional I/O port characteristics are summarized below:
• Two of the KPCI-3160 general-purpose I/O lines can be alternatively configured via soft-
ware to be external interrupt enable input, INT_ENN, and external interrupt request input,
INT_REQ.
• The KPCI-3160 can output higher currents than the industry standard 8255 chip. Output cur-
rent capabilities of 15mA (source) and 64mA (sink) allow it to control many LEDs, up to 22
modules, and Keithley relay boards.
NOTE The maximum current on each +5V and digital ground pin is 1A, limit-
ing the total current to 2A.
• The PA, PB, and PC ports can always be read-accessed, regardless of the direction they were
initially configured for, without the external signal level being affected. For example, when a
port is configured as an output, it is still possible to execute a read of that port. The data
returned by the read is the data in the I/O register.
• On power-up or whenever the computer’s hardware reset line is asserted, all ports are cleared
and set as inputs, and interrupts are configured to start on the rising edge of the interrupt
request signal (default configuration).
• The four groups of PA, PB, and PC ports interface to user I/O connections via a standard
100-pin connector. Using a CONN-3160-D1 accessory, the KPCI-3160 board can be con-
nected to the same I/O accessories as can the KPCI-PIO96 and PIO-96J boards.
• Five volt power from the computer power supply is made available at the I/O connector, for
use in external circuits.
Software
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 pro-
gramming. LabVIEW is a fully featured graphical programming language used to create virtual
instrumentation.
Refer to Section 3, “Installation,” for more information about software.

3-2 Installation KPCI-3160 User’s Manual
Section 3 describes the following operations, in the order in which they should be performed:
• Reviewing software options and installing software (installation notes that supplement the
Read this first sheet).
• Preparing for and doing physical installation of the board.
• Configuring the installed software and board.
• Identifying I/O connector pins, connecting the board to interface accessories, and wiring the
I/O to external circuits.
NOTE Install the DriverLINX software before installing the KPCI-3160 board.
Otherwise, the device drivers will be more difficult to install.
Installing the software
Software options
The KPCI-3160 has 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 sum-
mary of the pros and cons of using integrated packages or writing custom programs is provided
in the Keithley Full Line Catalog. The KPCI-3160 has fully functional driver support for use
under Windows 95/98/NT.
NOTE DriverLINX must be installed to run any applications for the board,
whether they are custom-programmed applications or integrated soft-
ware packages, such as TestPoint or LabVIEW.
DriverLINX driver software for Windows 95/98/NT
DriverLINX software, supplied by Keithley with the KPCI-3160 board, provides convenient
interfaces to configure and set I/O bits without register-level programming.
Most importantly, however, DriverLINX supports those programmers who wish to create cus-
tom applications using Visual C/C++, Visual Basic, or Delphi. DriverLINX accomplishes fore-
ground 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

KPCI-3160 User’s Manual Installation 3-3
In addition to basic I/O support, DriverLINX also provides:
•Built-in capabilities to handle memory and data buffer management.
•A selection of starting and stopping trigger events, including pre-triggering, mid-point trig-
gering, 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-3160 board.
DriverLINX is essentially hardware independent, because its portable APIs work across various
operating systems. This capability eliminates unnecessary programming when changing operat-
ing 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, without program-
ming, 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 pro-
vides 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 instrumen-
tation. 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, con-
trol, and analysis routines. Also included are debugging tools, help windows, execution high-
lighting, 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-3160.
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 sup-
port. Both TestPoint and LabVIEW support require DriverLINX to
access the board’s hardware resources.
