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.

*Any CD ROM drive that came installed with the required computer should be satisfactory. However, if you have post-

installed an older CD-ROM drive or arrived at your present system by updating the microprocessor or replacing the
motherboard, be aware that some early CD-ROM drives do not support the long file names often used in 32-bit
Windows files.

Functional description

The KPCI-3160 is a 96-bit parallel digital interface board designed for the PCI bus. The
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.

Pentium or higher processor on motherboard with PCI bus version 2.1.
Windows® 95 or higher.
Windows® NT version 4.0 or higher.
16 MB or greater RAM when running Windows® 95 or 98.
32 MB or greater RAM when running Windows® NT.
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

KPCI-3160 board, which draws 15W maximum at 5VDC.

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 pack­ages 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 soft­ware 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 cur­rent capabilities of 15mA (source) and 64mA (sink) allow it to control many LEDs, up to 22
modules, and Keithley relay boards.

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 con­nected 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.

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.

The maximum current on each +5V and digital ground pin is 1A, limit­ing the total current to 2A.

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 sum­mary 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,

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 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.

Install the DriverLINX software befor e installing the KPCI-3160 board.
Otherwise, the device drivers will be more difficult to install.

whether they are custom-programmed applications or integrated soft­ware packages, such as TestPoint or LabVIEW.

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 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, without program­ming, 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-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.

3-4 Installation KPCI-3160 User’s Manual

Installing application software and drivers

Installing the TestPoint support

It is anticipated that, in the future, TestPoint will implicitly support the KPCI-3160 board with­out installing additional drivers. Check with the following concerning current availability of
TestPoint support for the KPCI-3160:

• 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-3160 board, you need
not install a special driver. 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-3160 board

This subsection helps you to do the following:

• Prepare for the board installation.

• Physically install the board.

CAUTION Ensure that the computer is turned OFF before installing or remov-

ing a board. Installing or removing a board while power is ON can
damage your computer, the board, or both.

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-3160 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-3160 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-3160 boards. The user must not assume that installation of the CE-marked KPCI-3160 in
a CE-marked PC will result in a system with acceptable RFI emissions.

Unwrapping and inspecting the board

NOTE Install the DriverLINX software before installing the KPCI-3160 boar d.

Otherwise, the device drivers will be more difficult to install.

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 KCPI-3160 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.”

Installing the board

Install a KCPI-3160 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.”

Connecting interface accessories

CAUTION If a cable is connected to any external circuits, make sure power to

all external circuits is turned OFF before connecting this cable to the
KPCI-3160 board. Connecting a powered external circuit to the
board can damage the board, the external circuit, or both.

Handle the board at the mounting bracket, using a grounded wrist
strap. Do not touch the circuit traces or connector contacts. If you do
not have a grounded wrist strap, periodically discharge static elec­tricity by placing one hand firmly on a grounded metal portion of the
computer chassis.

The KPCI-3160 I/O connector can be mated directly to your external circuits using locally fabri­cated cable assemblies. To mate a locally fabricated cable to an I/O connector, install a 3M type
101A0-6000EC connector on the cable.

NOTE The 100-pin mating connector is NO T available in a solder -cup version;

use of the specified connector will requir e appr opriate cable and tooling
to make a reliable insulation displacement connection.

Alternatively, the connectors can be mated to your circuits via manufactured cable assemblies
and interface accessories, such as an adapter accessory and screw terminal boards. Use of such
accessories is described in the next subsections.

Using a CONN-3160-D1 accessory

The CONN-3160-D1 is an adapter accessory for the KPCI-3160 board, as shown in Figure 3-3.
It provides four 50-pin connectors that are identical to the four 50-pin connectors of the
KPCI-PIO96 and PIO-96J boards. These four connectors allow all accessories that work with
both KPCI-PIO96 and PIO-96J boards to be used with the KPCI-3160 board. (Refer to the next
subsection.) The correspondence between the pins of the CONN-3160-D1 50-pin connectors
and the pins of the KPCI-3160 I/O connector is shown in Table 3-2, Table 3-3, Table 3-4, and

Table 3-5.

The CONN-3160-D1 accessory interfaces to the KPCI-3160 via a CAB-1800 cable. The
CAB-1800 cable is a 100-conductor cable with a 100-pin D-type connector on each end.

Using an STP-100U accessory

The STP-100U is an adapter accessory for the KPCI-3160 which simply brings all 100 pins of
the connector to screw terminals. Pin assignments are the same as for the CONN-3160-D1 P1
connector. This differs from the KPCI-3160’s P101 connector, see cabling caution below.

NOTE While the STP-100 has a similar appearance , it uses a different pin num-

bering scheme compatible with the DAS/KPCI-180xHC series, and con­nects certain signal lines together. Because of this, it cannot be used as
an accessory with the KPCI-3160 board.

Cabling caution for accessories

Note that the CAB-1800 series is not a 1-1 cable. Because of its construction, pin assignments
on one end are mirrored from that on the other end. This is why the pin numberings (and there­fore screw terminal assignments) on the accessories are not the same as those of the KPCI-3160
P101 connector. Use the provided tables (Table 3-2 through Table 3-5) to identify the correct
connection.

Wiring I/O to your external circuits

CAUTION Ensure that both the computer and the external circuits are turned

OFF before making any connections. Making connections while the
computer and external circuits are powered can damage the com­puter, the board, and the external circuits.

External circuits must properly match the input and output requirements of the board. For exam­ple, input signals often require pull-up resistors and elimination of contact bounce. The follow­ing subsection presents pull-up and de-bounce circuits and discusses using +5VDC power from
the board for these and other applications.

Monitoring contact closure at an input

To ensure that the KPCI-3160 reliably monitors an open contact as an input-high condition, con­nect a 10kW pull-up resistor between the input line and a +5VDC source. See Figure 3-5.

Eliminating contact bounce at an input

The effects of contact bounce may be eliminated by programming in your application software.
However, it is often desirable to eliminate contact bounce from the signal, using a de-bounce cir­cuit between the contacts and the KPCI-3160 input. Figure 3-6 shows a typical de-bounce circuit
that can be used with Form C contacts.

Using +5VDC from the computer power supply

CAUTION Do not connect the +5VDC outputs to an external +5VDC supply.

This may damage the external supply, the board, and the computer.

Do not draw more than 2.0A, total, from the board to power external
circuits, distributed as follows:

• Do not draw more than 1A, total, at the KPCI-3160 I/O connec­tor between pin 51 (+5VDC) and pin 100 (digital ground).

OR

at CONN-3160-D1 50-pin connectors J1 and J2 combined,
between pins 49 (+5VDC) and the even-numbered pins (digital
grounds).

• Do not draw more than 1A, total, at the KPCI-3160 I/O connec­tor between pin 01 (+5VDC) and pin 50 (digital ground).

OR

at CONN-3160-D1 50-pin connectors J3 and J4 combined,
between pins 49 (+5VDC) and the even-numbered pins (digital
grounds).

Drawing excessive current may damage the KPCI-3160 board and,
potentially, the computer.

The board extends fuse-protected power from the +5VDC computer supply to the I/O connector.
(See Figure 3-1). This power is convenient for use in light external circuits, such as pull-up resis-
tors. If you ensure that the conditions in the above CAUTION notice are maintained, this power
may also be used to energize external accessories, provided that your computer’s power supply
is capable of delivering the desired current.

External Interrupts

4-2 External Interrupts KPCI-3160 User’s Manual

Using DriverLINX, you can arrange for a piece of software code to run every time that the board
detects the rising edge and/or the falling edge of an external interrupt signal. Section 4 explains
external interrupt signal connections and summarizes interrupt usage for the KPCI-3160 board.
For more information, refer to Using DriverLINX with Your Har dwar e—K eithley 3160 and other
DriverLINX manuals.

External interrupt description

Through DriverLINX, you can alternatively configure two of the general-purpose I/O lines of
port group 3—PC7 and PC6—for the following external interrupt functions:

• INT_ENN (external interrupt enable, active low)

• INT_REQ (external interrupt request, edge triggered)

The interrupt pins on the I/O connector of the KPCI-3160 board, and the corresponding pins on
the J4 connector of the CONN-3160-D1 accessory, are identified in Table 4-1.

FunctionDescription

Through DriverLINX, you can independently configure any of the four port groups so that an
external interrupt request pulse latches the data sent to the input ports.

Through DriverLINX, you can also configure interrupts to be edge-triggered for any of the fol­lowing conditions:

• The rising (positive) edge of the external interrupt request signal

• The falling (negative) edge of the external interrupt request signal

• Both the rising and falling edges of the external interrupt request signal

NOTE Positive-edge triggering is the default upon power-up or reset.

In principle, if you configure interrupts to occur on both the rising and falling edges of the exter­nal interrupt request signal, each signal generates two interrupt requests—the on-period width of
the external interrupt request signal determining the time between these two requests. However,
in practice, be aware that the falling edge of the external interrupt signal is effective only if the

interrupt signal is on longer than the combined overhead and data processing time initiated by
the rising edge of the signal. If the falling edge of the signal occurs during data processing initi-

ated by the rising edge of the signal, then the falling edge of the signal will not be effective—it
will be missed. Refer to the next subsection, “External interrupt application,” for more informa­tion about missed interrupts.

KPCI -3160 User’s Manual External Interrupts 4-3

External interrupt application

Typically, you would use an external interrupt to ensure that the application program processes,
at a specific time (or at two specific times, if both positive-edge and negative-edge triggering are
used), specific data that are present at one or more ports. You can do this with a KPCI-3160
external interrupt, subject to the following limitations:

• A KPCI-3160 external interrupt signal indiscriminately triggers data transfer from all twelve

I/O ports: both data that does need to be processed and data that does not need to be pro­cessed. The board provides no way to assign interrupts or intrinsically detect the interrupt
status for a specific port. (However, you could potentially hardware-set and software-detect
certain I/O bits to tell a custom application program which ports to process for a given inter­rupt. Or you could compare the current and previous data sets, and then process only
changed data.)

• Conversely, if processing needs and interrupts occur too frequently, data that does need to be
processed can be missed. External interrupt signals are ignored during an interrupt service
routine (ISR) while an interrupt-pending bit is set high—except that the first interrupt miss,
only, does set an interrupt-missed bit.

Therefore, you must 1) know how fast your host computer and application software can process
data, and 2) space important data and interrupts accordingly. Of course, this requirement is not
specific to the KPCI-3160 board. It applies to any data acquisition board.

You must also ensure, at the end of interrupt-initiated processing, that the application program
resets the interrupt-pending bit, the interrupt-missed bit, and two other bits that recorded
whether the interrupt occurred on the rising or falling edge of the interrupt request signal.

DriverLINX handles this automatically.

Refer to Table 4-2 for a list of external-interrupt responses.

For an additional application illustration, refer to the “Interrupt example scenario” subsection in

Appendix B. For information on setting and configuration of external interrupts, refer to your

DriverLINX software manuals.

NOTE Do not confuse the external interrupt INT_REQ with the internal PCI

bus interrupt INTA, even though INT_REQ and INTA are linked by soft­ware. (The PCI b us shar es one interrupt line, INTA, for all boards. INTA
interrupts the host computer each time a transfer is occurring.)

KPCI-3160 User’s Manual Troubleshooting 5-3

If your board is not operating properly after using the information in Table 5-1, continue with
“Systematic problem isolation” to further isolate the problem.

Systematic problem isolation

General problem isolation procedure

If you were unable to isolate the problem using Table 5-1, then follow Figure 5-1 and the accom-
panying written procedure. The flowchart in Figure 5-1 summarizes how to systematically check
and eliminate some problem causes. The corresponding written procedure amplifies the flow­chart steps with more detail.

CAUTION Always turn OFF your computer and any external circuits con-

nected to the KPCI-3160 board before removing or replacing the
board. Removing or replacing a board with the power ON can dam­age the board, the computer, the external circuit, or all three.

Handle the board at the mounting bracket, using a grounded wrist
strap. Do not touch the circuit traces or connector contacts. If you do
not have a grounded wrist strap, periodically discharge static elec­tricity by placing one hand firmly on a grounded metal portion of the
computer chassis.

NOTE In the following procedure, the term “board” always refers to a

KPCI-3160 board. The procedure never directs you to install or remove
any type of PCI board other than a KPCI-3160 board.

In Figure 5-1, the number in brackets in each flowchart block (e.g
refers to the corresponding step number in the verbal procedure. If mul­tiple blocks in the flowchart have the same number, each of those blocks
is part of a single verbal step. Conversely, if there is a range of numbers
in the brackets (e.g . [4, 5, 6]), the block summarizes multiple verbal steps.

The logic in this procedure assumes that the problem has only one
cause. Therefore, once a cause is found and corrected, the reader is
instructed to reassemble the system and verify proper operation.

KPCI-3160 User’s Manual Troubleshooting 5-5

To further isolate the problem to the KPCI-3160 board or to the host computer, use the following
steps:

1. Check if board damage is seen on inspection. Proceed as follows:

NOTE If more than one KPCI-3160 board is installed in your computer, dis-

connect, remove, and check all KPCI-3160 boards.

a. Turn power OFF to the host computer.

b. Turn power OFF to all external circuits and accessories connected to all installed

KPCI-3160 boards.

c. From each installed KPCI-3160 board, unplug the CONN-3160-D1 accessory (or

in-house-wired 100-pin mating connector) that is wired to external circuits.

NOTE Do not disconnect any cir cuits from the CONN-3160-D1 and associated

accessories (or from the in-house-wired 100-pin mating connector, if
you used that instead).

d. Remove all KPCI-3160 boards from the computer.

e. Visually inspect all KPCI-3160 boards for damage.

2. Based on the results of step 1, do the following:

• If all KPCI-3160 boards are not obviously damaged, continue with step 3 and check for

host computer malfunction.

• If a board(s) is obviously damaged on inspection, repair or replace the board. Refer to

“Technical support” for information on returning the board for repair or replacement.
Skip to step 27.

3. Check if the computer functions satisfactorily by itself. Proceed as follows:

a. Remove all KPCI-3160 boards from the host computer.

b. Turn ON power to the host computer.

c. Perform any necessary diagnostics to the computer hardware and operating system.

4. Based on the results of step 3, do one of the following:

• If the computer functions satisfactorily, the problem must lie elsewhere; do the following

steps:
a. If you have another KCPI-3160 board that you know is OK, i.e. works properly, then

continue with step 5.

b. If you do not have another KCPI-3160 board that you know is OK, i.e. works prop-

erly, read the instructions in “Technical support.” Then contact Keithley for help in
isolating the cause of your problem.

• If the computer does not function satisfactorily, do the following steps:

a. Diagnose and fix the computer malfunction.
b. Assume that fixing the computer malfunction has solved your problem, and skip to

step 27.

5. Prepare for PCI resource checks in step 6 by clearing any KPCI-3160 board listings from the
Windows 95/98 device manager. If any KPCI-3160 boards are listed, the computer could
falsely report as PCI resources one or more of the now-empty PCI slots that previously held
the KPCI-3160 boards.

Proceed as follows for the Windows 95/98 operating system. (A different procedure is
required for Windows NT.):

a. Right-click the My Computer icon on your desktop.

b. On the menu that appears, click Properties.

5-6 Troubleshooting KPCI-3160 User’s Manual

c. On the System Properties dialog box that appears, click the Device Manager tab. The

Device Manager appears.

d. In the Device Manager look for a DriverLINX drivers item.

• If you find a DriverLINX drivers item with a + sign to the left of the item, click the
+ sign. A second level list may appear containing one or more KPCI-3108 boards.

• If you do not find a DriverLINX drivers item, skip to step 6.

e. Delete any KPCI-3160 boards, only, from the list, by highlighting the item and clicking

the Remove button.

6. Check if the computer finds an OK board to be a PCI resource in a slot from which you
removed a KPCI-3160 board.

a. Shut down Windows 95/98/NT and turn OFF power to the host computer.
b. Perform the procedure “Checking for board as a PCI resource” found later in Section 5.

7. If you had originally installed additional KPCI-3160 boards in other PCI slots, then repeat
step 6 with the OK board in each of these other slots.

8. Based on the results of steps 6 and 7, do one of the following:
a. If the board is recognized as a PCI component in all slots tested, then there may be soft-

ware issues. Skip to step 16.

b. If the OK board is not recognized as a PCI component in all slots tested, then a PCI slot

connector(s) is suspect. Continue with step 9.

9. Make sure that the suspect slot connector and the board contacts have been wiped adequately
and are properly mated. Do the following:

a. Turn OFF power to the host computer.
b. Remove and reseat the board a few times in the suspect PCI slot connector. This creates a

wiping action to improve the probability of good contact.

c. Make sure that the board is firmly seated in the suspect PCI slot connector.

d. Replace the cover of the computer.

e. Turn ON power to the host computer.

10. Check if the computer now finds the OK board to be a PCI resource in the suspect slot con­nector. Use step 3, only, of the procedure “Checking for board as a PCI resource.”

11. If you found more than one suspect slot connector, then repeat steps 9 and 10 with the OK
board in the other suspect slot connectors.

12. Based on the results of steps 9 through 11, do one of the following:

• If the board was recognized as a PCI resource in all slots tested, then the cause of the

problem was probably high contact resistance, which apparently has been corrected by
the wiping action. Skip to step 27.

• If the OK board was not identified as a PCI resource in all slots tested, then any slots in

which it was not identified are still suspect. Continue with step 13.

13. Based on the history of steps 6 through 12, do one of the following actions,

• If, at this point, both of the following are true, then install and test the OK board in a pre-

viously unused slot to confirm that the originally tested slot(s) (rather than some other
factor) was at fault:

– The OK board was not identified as a PCI resource in any slot that you tested.
– You have a PCI slot that was unused before you started the problem isolation scheme.

Proceed as follows:

a. Turn OFF power to the host computer.
b. Move the OK KPCI-3160 board to the slot that was unused before you started the

problem isolation scheme.

c. Reinstall the cover of the computer.

KPCI-3160 User’s Manual Troubleshooting 5-7

d. Perform step 3, only, of the procedure “Checking for board as a PCI resource,” found

later in Section 5.

e. Continue with step 14.

• If, at this point, you do not have a PCI slot that was unused before you started the prob­lem isolation scheme, continue with step 14.

14. Based on the history of steps 6 through 13, do one of the following:

• If, at any point in steps 6 through 13, the OK board was identified as a PCI resource in at
least one slot on the host computer, then any slot in which it did not work is likely defec­tive. Continue with step 15.

• If you only had one slot in which to install the OK board, assume that this slot is defec­tive. Continue with step 15.

• However, if at this point you have tested the OK board in multiple slots and the board has
not been identified as a PCI resource in any slot, then the cause of your problem may be
outside the scope of these diagnostics. Read the instructions in “Technical support,” and
then contact Keithley for help in isolating the cause of your problem.

15. Replace the defective slot connector, as follows:
a. Turn OFF the computer.

b. Remove the OK board.

c. Have a qualified service person replace the defective PCI slot connector.

d. Skip to step 27.

16. Continuing from step 8, check whether DriverLINX is installed and configured properly to

work with the board and, if problems are found, try to remedy them.

a. Check whether you can start the AIO Panel. Refer to steps 1a through 1d of “Checking

the combined board and DriverLINX installations” in Section 3.

b. Based on the results of step 16a above, do one of the following:

• If the AIO Panel starts, the board and DriverLINX are installed and configured prop­erly. Skip to step 17 of the problem isolation scheme. Your problem may be caused by
faulty I/O.

• If the AIO Panel does not start, the combined board and DriverLINX are not config­ured properly, or DriverLINX is not installed properly. Continue with step 16c of the
problem isolation scheme.

c. Perform steps 2 through 4 of “Checking the combined board and DriverLINX installa-

tions” in Section 3.

d. Based on the results of step 16c above, do one of the following:

• If the AIO Panel now starts, then skip to step 27.

• If the AIO Panel still does not start, then your problem may be outside the scope of

these diagnostics. Read the instructions in “Technical support,” and then contact Kei-
thley for help in isolating the cause of your problem.

17. Perform the following I/O bit tests to determine whether you can write and read all I/O bits
to and from the OK board: the I/O loop-back test and the output set test. Perform either or
both of these tests, outlined separately under the headings “I/O loop-back test” and “Output

set test.” However, only the I/O loop-back is conclusive and is therefore strongly preferred.

18. Based on the results of step 17, do one of the following:

• If you can write and read all I/O bits to and from the OK board, skip to step 21.

• If you cannot write and read all I/O bits to and from the OK board, there may be data

acquisition program errors or defective slot contacts corresponding to I/O bits; continue
with step 19.

5-8 Troubleshooting KPCI-3160 User’s Manual

19. You have arrived at this step because you cannot write and read all I/O bits to and from the
OK board. You may have already tried some data acquisition program source-code debug­ging. Do one of the following:

• If either of the following statements are true, then continue with step 20.

– You have arrived at step 19 before debugging the source code.
– You have arrived at step 19 after debugging the source code once, but you have not

yet tried to find more code bugs after two or more I/O test failures.

• If both of the following statements are true, then the cause of your problem may be out-

side the scope of these diagnostics. Read the instructions in “Technical support,” and then
contact Keithley for help in isolating the cause of your problem:

– You have arrived again at step 19 after having debugged the source code at least once

and after having failed the I/O bit tests at least a second time.

– You have tried to find more code bugs after two or more I/O test failures and cannot

find any more bugs.

20. Thoroughly check if all data acquisition program source-code lines are OK. Check the pro­gram documentation and/or use a debugger to look for programming errors that may be caus­ing the problem.

• If programming errors are found, do the following:

a. Debug and fix all known data acquisition program errors.
b. Repeat steps 17 and 18.

• If no programming errors are found after thorough debugging, then the cause of your

problem may be outside the scope of these diagnostics. Read the instructions in “Techni-

cal support,” and then contact Keithley for help in isolating the cause of your problem.

21. If you can write and read all I/O bits to and from the OK board, do the following:

• If you have arrived at step 21 after program corrections have been made, and you can

now write and read all I/O bits to and from the OK board, then the problem has appar­ently been resolved. Skip to step 27.

• If you have arrived at step 21 without making data acquisition program corrections and

can write and read all I/O bits to and from the OK board, then faulty external I/O connec­tions may have caused your problem. Continue with step 22.

22. Check for external wiring faults as follows:
a. Into the OK KPCI-3160 board, plug back one of the CONN-3160-D1 accessories (or a

in-house-wired 100-pin mating connector) that is wired to external circuits. You
unplugged one or more of these in step 1.

b. Check each external I/O connection, one at a time, for short circuits and open circuits and

immediately correct any faults as you find them.

c. If KPCI-3160 boards were installed in more than one PCI slot, repeat steps 22a and 22b

until all external circuits have been checked and all faults have been corrected.

23. Based on the results of step 22, do the following:

• If any external I/O connection faults were found and corrected, assume that your prob-

lems were caused by the faulty connections. Skip to step 27.

• If all external I/O connections were found to be normal, then, by process of elimination,

the KPCI-3160 board(s) originally installed in the computer is likely the cause of the
problem. Continue with step 24.

KPCI-3160 User’s Manual Troubleshooting 5-9

24. Replace the faulty board(s). Do one of the following:

• If only one KPCI-3160 board was installed when the problem occurred, proceed as fol­lows:

a. Leave the OK board in the expansion slot as a replacement. To repair or replace the

faulty board, contact Keithley as described in “Technical support.”

b. Skip to step 27.

• If more than one board was installed when the problem occurred, determine which one is
faulty, starting with step 25.

25. Check whether an original board—a board that you removed in step 1—is detected as a PCI
resource. Proceed as follows for the Windows 95/98 operating system (a different procedure
is required for Windows NT):

a. Turn OFF the computer.

b. Remove the OK KPCI-3160 board.

c. Reinstall the computer cover.

d. Turn ON the computer.

e. Clear KPCI-3160 boards from Windows 95/98 device manager, if any are listed. (Other-

wise, when you reboot the computer, the computer may still say that empty PCI slots that
once held the OK KPCI-3160 board are PCI resources.) Proceed as follows:

1. Right-click the My Computer icon on your desktop.

2. On the menu that appears, click Properties.

3. On the System Properties dialog box that appears, click the Device Manager tab. The

Device Manager appears.

4. In the Device Manager, look for a DriverLINX drivers item.

5. If you find a DriverLINX drivers item with a + sign to the left of the item, click the
+ sign. A second level list may appear containing one or more KPCI-3108 boards.

6. Delete any KPCI-3160 boards, only, from the list, by highlighting the item and click­ing the Remove button.

f. Perform step 1, only, of the procedure “Checking for board as a PCI resource,” found

later in this section.
g. Turn OFF the computer.
h. Install one of the original KPCI-3160 boards in a PCI slot known to be satisfactory.

i. Reinstall the computer cover.
j. Perform step 3, only, of the procedure “Checking for board as a PCI resource,” found

later in this section.
k. Based on the results of step 25j, do one of the following:

• If, in step 25j, the original board that you checked is not recognized as a PCI
resource, you have located the faulty board. Do the following:

1. Replace it with the OK board. (To repair the faulty board or obtain a new one,

contact Keithley as described in “Technical support.” )

2. Skip to step 27.

• If, in step 25j, the original board that you checked is recognized as a PCI resource,
but you have not yet checked all original KPCI-3160 boards as PCI resources, repeat
steps 25e through 25k for each additional original board.

• If you have reached this point after checking all original KPCI-3160 boards as PCI
resources, and each board has been recognized as a PCI resource, then continue with
step 26. Probably one of the boards has faulty I/O.

5-10 Troubleshooting KPCI-3160 User’s Manual

26. Determine which original board has faulty I/O. If the faulty board survived the PCI resource
test in step 25, it should fail the I/O test.

a. If an original board remains installed following step 25, then skip to step 26e.
b. Turn OFF the computer.

c. Install one of the original boards in a slot known to be satisfactory.

d. Turn ON the computer.

e. Perform the test outlined in the “I/O loop-back test” subsection. Then return to this step

(26e).

f. Based on the results of step 26e, do one of the following:

• If, in step 26e, you cannot write and read all I/O bits to and from the first original

KPCI-3160 board that you test, you have located the faulty board; replace it with the
OK board. (To repair the faulty board or obtain a new one, contact Keithley as
described in “Technical support.”) Then skip to step 27.

• If, in step 26e, you can write and read all I/O bits to and from the first original

KPCI-3160 board that you test, repeat steps 26b through 26e for additional original
KPCI-3160 boards until you find a faulty board. Replace the faulty board with the
OK board. (To repair the faulty board or obtain a new one, contact Keithley as
described in “Technical support.”) Then continue with step 27.

• However, if you have reached this point after trying all original boards, and the I/O on
each board has been found satisfactory, then the cause of your problem may be out­side the scope of these diagnostics. Read the instructions in “Technical support,” and
then contact Keithley for help in isolating the cause of your problem.

27. Assuming the problem has been resolved, do the following:
a. Turn OFF the computer.
b. Install the good KPCI-3160 boards in good slots.

c. Reinstall the computer cover.

d. Reconnect all external circuits as discussed in Section 3, “Installation.”

e. Turn ON the computer.

f. Verify that the system now performs satisfactorily.

28. Based on the results of step 27f, select one of the following:

• If the system now performs satisfactorily, you have successfully isolated and corrected

the problem.

• If the system still does not perform satisfactorily, then the cause of your problem may be

outside the scope of these diagnostics. Read the instructions in “Technical support,” and
then contact Keithley for help in isolating the cause of your problem.

KPCI-3160 User’s Manual Troubleshooting 5-11

Specified tests

Checking for board as a PCI resource

CAUTION The test outlined in this subsection involves handling of the

KPCI-3160 circuit board. Handle the board at the mounting bracket,
using a grounded wrist strap. Do not touch the circuit traces or con­nector contacts. If you do not have a grounded wrist strap, periodi­cally discharge static electricity by placing one hand firmly on a
grounded metal portion of the computer chassis.

Ensure that the computer is turned OFF before installing or remov­ing a board. Installing or removing a board while power is ON can
damage your computer, the board, or both.

Always reinstall the cover before turning the computer ON.

NOTE The following procedure depends on the Plug and Play capability of

Windows 95 or 98. If your computer operating system is Windows NT,
you must use a different pr ocedur e to detect the boar d as a PCI r esour ce.
Consult your Windows NT documentation.

The following procedure provides details to help you determine whether Windows 95/98 Plug
and Play finds your KPCI-3160 board as a PCI resource.

1. Determine the PCI resources that Plug and Play detects before any KPCI-3160 boards are
installed. Proceed as follows:

a. Insert a blank diskette, or any diskette that you are sure is unbootable, into the A: drive.

b. Turn ON the computer and allow it to start the boot cycle.

The boot cycle stalls at a text screen listing system characteristics and resources and say­ing at the bottom: Non-system disk or disk error. Replace and press any key when

ready.

NOTE This system characteristics and resources screen is normally displayed

only fleetingly during the boot cycle. Having an unbootable diskette in
your computer automatically stops the boot cycle at this screen, allow­ing for convenient viewing. This is not harmful to your computer. The
more common appr oach—using the P
this screen—requires fast reflexes with some systems.

c. Note the displayed list of PCI devices under a heading something like PCI device

listing… If you have a printer, print the screen by pressing the PRINT SCREEN key.

d. Remove the diskette and allow the boot cycle to finish.

2. Install a good board—a KPCI-3160 board that you know is fully functional—as follows:

a. Shut down Windows 95/98 and turn OFF power to the host computer.

b. Install the good board in a slot from which you removed a potentially faulty board. Refer

to “Installing the KPCI-3160 board” near the beginning of Section 3, for board installa­tion instructions.

c. Reinstall the cover of the computer.

AUSE key to pause the boot cycle at

5-12 Troubleshooting KPCI-3160 User’s Manual

NOTE If you removed more than one board in step 1, install only one good

board in one expansion slot.

Do not connect any external circuits to the board at this point.

3. Again determine the PCI resources detected by your computer, after the KPCI-3160 board is
installed. Windows 95/98 Plug and Play should find and configure the new board as a PCI
resource if all of the following are true:

• The board functions properly as a PCI device.

• The contacts of the expansion slot in which the OK board is installed are in good

condition.

• The OK board is seated properly in the expansion slot.

Do the following, as you did in step 1:

a. Insert an unbootable diskette.
b. Turn ON the computer and allow the boot cycle to stall at the Non-system disk or disk

error… message.

c. Again, note the displayed list of PCI devices. A new device should be listed, likely as an

unidentified peripheral. If your resource listing includes PCI slot numbers, the slot num­ber for the new device should match the number of the slot in which your board is
installed.

d. Remove the diskette and allow the boot cycle to finish.

I/O bit tests

CAUTION The tests outlined in this subsection involve handling of the

KPCI-3160 circuit board. Handle the board at the mounting bracket,
using a grounded wrist strap. Do not touch the circuit traces or con­nector contacts. If you do not have a grounded wrist strap, periodi­cally discharge static electricity by placing one hand firmly on a
grounded metal portion of the computer chassis.

Ensure that the computer is turned OFF before installing or remov­ing a board. Installing or removing a board while power is ON can
damage your computer, the board, or both.

Always reinstall the cover before turning the computer ON.

The I/O bit tests check whether the input and output functions of the board are operating prop­erly. They also act as backup tests for a defective slot connector. Of the two tests outlined below,
only the I/O loop-back test is conclusive and is therefore strongly preferred.

These tests are intended to be used when requested in the “General problem isolation proce-

dure.” However, they may also be used for general performance checks.

KPCI-3160 User’s Manual Troubleshooting 5-13

I/O loop-back test

The I/O loop-back test checks input and output bit performance.

You prepare a specially wired loop-back connector that, for each of the four port groups that you
test, connects the bits of port A to the corresponding bits of ports B and C. (Alternatively, you
wire the screw terminals of an STP-50 or STA-50 accessory and connect a CACC-2000 cable.)
The loop-back connections are summarized in Table 5-2.

Table 5-2

Loop-back connection summary

Connect these bits
configured as an output

to these bits configured
as inputs

After connecting a CONN-3160-D1 accessory to your KPCI-3160 board, you insert the
loopback connector into connector J1 of the CONN-3160-D1 accessory. Then, you use a
DriverLINX graphical interface (AIO Panel) to configure the bits of port group 0, port A as
outputs and the bits of port group 0, ports B and C, as inputs. Thereafter, you use this same
DriverLINX graphical interface to set two different bit patterns at port A and to check in each
case for corresponding bit patterns at ports B and C.

If all bits correspond for the first port group, you repeat the loop-back test for each of the other
three port groups. The board is performing satisfactorily if all 96 bits respond appropriately.

Perform the loop-back test as follows:

1. Prepare a loop-back test connector, using a female 50-pin connector that mates with any of
the 50-pin connectors on the CONN-3160-D1 accessory. This can be purchased as 3M part
no. 3425-6050. Wire the connector as shown in Figure 5-2.

Alternatively, wire an STP-50 or STA-50 screw terminal accessory as shown in Figure 5-2.
The screw terminal numbers and assignments for the STP-50 or STA-50 accessory are the
same as the pin numbers and assignments for the 3M 3425-6050 connector. After connecting
a CACC-2000 cable, you can use the wired STP-50 or STA-50 in the same way as a loop­back connector. (See Figure 3-4.)

NOTE Resistors in the loops are specified for safety. During the loop-back pro-

cedure, some of the interconnected bits could temporarily or inadvert­ently be configured both as outputs, and the board could be easily
damaged. These 1K ohm resistors limit the currents between bits to
below 15mA, which is within the source and sink current specifications
for the board. If you wish to use a different resistance value, the substi­tute resistance value must be at least 700 ohms.

2. Turn OFF the host computer.

3. Connect a CONN-3160-D1 accessory to your KPCI-3160 board. Refer to “Using a CONN-

3160-D1 accessory” in Section 3.

4. Insert the loop-back test connector, which you prepared in step 1, into the CONN-3160-D1
connector designated in Table 5-3. (For connector locations, see Figure 3-3.)

Alternatively, if you wired an STP-50 or STA-50 accessory instead of the 3M 3425-6050

Output set test

The output set test checks whether logic levels measured at all KPCI-3160 output pins agree
with output bit patterns set by software, using a DriverLINX graphical interface (AIO Panel).

NOTE This test is performed without user circuits being connected to the

outputs.

Perform the output set test as follows:

1. Ready the following equipment:

• A digital voltmeter (DVM) or a digital multimeter (DMM) set to measure voltages, or a
logic probe capable of reading TTL logic levels.

• A CONN-3160-D1 accessory and CAB-1800 cable.

• A means to reliably and safely connect the DMM/DVM or logic probe input to each

KPCI-3160 I/O point. The following alternatives are suggested, both of which mate with
the CONN-3160-D1 accessory:

– An STA-50 screw terminal accessory with attached CACC-2000 cable (refer to

“Using additional accessories” in Section 3).

– A 50-pin mating connector (3M part no. 3425-6050) with installed ribbon cable,

such that the meter or logic probe can be clipped to exposed conductors at the end of
the cable.

2. Turn OFF the host computer.

3. Connect the CONN-3160-D1 accessory to your KPCI-3160 board. Refer to “Using a

CONN-3160-D1 accessory.”

4. Into one of the CONN-3160-D1 50-pin connectors that is designated in Table 5-5, insert
either of the following:

• The CACC-2000 cable that is attached to the STA-50

• The cabled 50-pin mating connector.

• Measure the voltage between signal ground and each bit of ports A, B, and C with a

DMM or DVM. Make measurements at the STA-50 terminals or the cabled mating con­nector that is connected to the selected CONN-3160-D1 50-pin connector.

• Check the logic level for each bit of ports A, B, and C bit with a TTL logic probe. Make

measurements at the STA-50 terminals or the cabled mating connector that is connected
to the selected CONN-3160-D1 50-pin connector.

14. Each bit set to ON in the AIO Panel should output a logic-high signal at the corresponding
I/O terminal, corresponding typically to 4 volts (minimum of 2.2 volts) at a DMM/DVM.
Each bit set to OFF in the AIO Panel should output a logic-low signal at the corresponding
I/O terminal, corresponding typically to 0 volts (maximum of 0.8 volts) at a DMM/DVM. Do
one of the following:

• If the bit patterns set on the AIO Panel do not agree with the logic levels measured at the

I/O terminals, the board is not functioning properly. Stop here, and return to the step in

I/O Address Mapping

B-2 I/O Address Mapping KPCI-3160 User’s Manual

NOTE A typical user of the KPCI-3160 board does not need to read this appen-

dix (except perhaps for the supplementary interrupt illustration under
“Interrupt example scenario”). Register level programming of the
KPCI-3160 board is neither practical nor necessary for most users.
Register level interfacing with the PCI bus is more complex than with
the ISA bus. PCI board addresses are mapped automatically in I/O
space or memory, whereas ISA board addresses are assigned manually
by the user in I/O space.

However, under Windows 95/98 only, you may be able to reuse an exist­ing port I/O application program—if it was designed to work with the
industry-standard 8255 and 82C55 chips—by substituting the automati­cally-mapped address for the user-assigned address. Refer to “Using

existing port I/O software to manipulate control and data registers” at

the end of Appendix B.

The DriverLINX driver shipped with your board provides a user-friendly Application Program­ming Interface (API) that supports Visual C++, Visual Basic, and Delphi programming lan­guages under Windows 95/98 and Windows NT 4.0. You are encouraged to use the capabilities
of DriverLINX and ignore the rest of the information in this chapter (except perhaps the subsec­tion “Interrupt example scenario,” which may help you to understand how external interrupts
work).

However, there are circumstances in which advanced users may desire or need to bypass Driver­LINX entirely and write their own drivers. Alternatively, advanced users may wish to program
the KPCI-3160 at the register level using an ActiveX hosting language. Finally, some users may
wish to reuse an existing application program that makes port I/O calls to an ISA-bus digital I/O
board.

Appendix B discusses the following:

• General PCI address assignments

• Control and data register address assignments inside the I/O space, as follows:

– Assignments for a control and data register map that emulates the assignments of the

8255 and 82C55 chips

– Assignments for five bits of a special interrupt control/status register, including an exam-

ple scenario showing how the bits are used

• Some general requirements for manipulating control and data registers

• Reuse of an existing port I/O application program with the KPCI-3160 board

General PCI address assignments

The PCI specification allows each PCI-bus board to be assigned up to five distinct address
regions for general use at the discretion of the hardware designer. The first region, at base
address BADDR0, is mandatory per the PCI specification, as published by the PCI Special
Interest Group (PCISIG). The other four address regions, located at base addresses BADDR1,
BADDR2, BADDR3, and BADDR4, are optional. The PCI BIOS or the Plug and Play operating
system automatically allocates BADDR0 through BADDR4 at power-up, based on the PCI
boards that it finds installed at that time. After power-up, computer software can read PCI
configuration space to determine the location of BADDR0 through BADDR4. (The term
“computer software” hereafter in Appendix B refers to the combination of the application
programming interface (API)/driver—normally, DriverLINX—and the application program. For
information about application programming through DriverLINX, refer to your DriverLINX
documentation.)

KPCI-3160 User’s Manual I/O Address Mapping B-3

The KPCI-3160 uses BADDR0 and BADDR1 mapped in I/O space. These addresses are usable
only in the programmed I/O mode (register access through the CPU).

Register assignments

The KPCI-3160 registers are mapped in I/O space as follows:

• It uses locations offset from BADDR1 for its port I/O control and data registers

• It uses a location offset from BADDR0 (BADDR0 + 0x38) for a special interrupt control/sta-

tus register (The prefix 0x designates hexadecimal.)

It uses Base Address 0 + 0x34 for the firmware revision: 32-bit ASCII “A0xx.”

All offsets from the base address are specified as multiples of four bytes (modulo 4 addressing),
because each offset specifies a four-byte (32-bit) wide register.

NOTE The term “base” addr ess, as used in the following subsections, does not

have the same meaning for a PCI board, such as the KPCI-3160, as for
an ISA board. The base addr ess for your KPCI-3160 boar d is an addr ess
BADDR1 that is mapped in I/O space or memory and is assigned at
power-up by the PCI BIOS or the Plug and Play operating system. It
remains constant only as long as the computer is powered. It is not a
fixed, user-assigned I/O address such as 0x300 or 0x310 set on a DIP
switch, nor is it a fixed address such as is assigned for a printer.

Control and data registers

The control and data register map emulates the register map of the 8255A standard, for the 8255
and 82C55 chips in mode 0, with some additional features to implement interrupt control and
latching. The KPCI-3160 separates its 96 I/O lines into four port groups (0 through 3). There­fore, each port group has 24 I/O lines, which are divided into three 8-bit ports (A, B and C).

The data bits and control bits of each of the four port groups occupy a single 32-bit register. For
each port group, the register bits are assigned as follows:

Bits of each control
and data register

Contents

In the 8255 and 82C55 chips, the contents of data and control registers must be transferred eight
bits at a time. However, in the KPCI-3160 the contents of data and control registers may be
transferred either 8 bits or 32 bits at a time.

B-4 I/O Address Mapping KPCI-3160 User’s Manual

Control and data register addressing

The four I/O port groups use a total of four combined data-plus-control registers. The address of
each register is offset from BADDR1 at a separate 32-bit boundary. Refer to Table B-1; the pre-
fix “0x” in Table B-1 designates hexadecimal.

For safety, the values of bits 0, 1, 3, and 4 default to “1” upon computer reset or power-up, so that all ports start out as inputs.

2

If control bit 6 is set to “0” for one or more port groups and is set to “1” for the remaining port groups, all port groups are configured for both rising
(positive) edge and falling (negative) edge interrupt polarity.

Interrupt control/status register

The firmware of the KPCI-3160 board implements a 32-bit interrupt control/status register. This
register is located at BADDR0 + 0x38 offset, where 0x designates hexadecimal. A control bit of
the interrupt control/status register is used to configure the board for interrupt-based data trans­fer and processing. Two status bits are used to determine whether one or more interrupts are
pending or were missed during data processing. Two control bits provide for the selection of
interrupt polarity (falling or rising edge) and the enabling/disabling of the interrupt signal.

Interrupt control/status bit descriptions

The four interrupt control/status register bits are described in detail in Table B-3.

Interrupt example scenario

The following example is one possible scenario that may help you to understand and use the
KPCI-3160 interrupt feature. (This example is simplified, and some details may not apply to
your specific system or to your requirements.) It illustrates the workings of the interrupts and
bits 6, 12, 17, and 23 of the interrupt control/status register. (Refer also to Section 4, “External

Interrupts.”)

1. At some point, computer software sets interrupt-enable bit 12 of the interrupt control/status
register to logic-high. (The term “software” here refers to the combination of the application
programming interface (API)/driver—normally, DriverLINX—and the application program.
To understand how to program interrupt-triggered data acquisition through DriverLINX,
refer to your DriverLINX documentation.) This status, detected by board firmware, enables
the board to process data using external interrupts. It changes general-purpose inputs PC6
and PC7 of port group 3 into external interrupt request and external interrupt enable inputs
INT_REQ and INT_ENN

2. At some point, computer software sets latching polarity bit 6 for port group 0 to determine
whether that data at port group 0 latches on the rising or falling edge of INT_REQ. This
action is repeated for port groups 1, 2, and 3.

3. Prior to sending data, a user circuit sets INT_ENN to logic low. Board firmware detects that
INT_ENN is low and allows the edges of interrupt signals at INT_REQ to be detected.

4. When data is ready to be transferred and processed, the user circuit sends an external inter­rupt request signal to INT_REQ.

5. Board firmware detects the rising or falling edge of the INT_REQ signal, depending on
interrupt polarity settings in the port-group control registers (Table B-2).

6. Software sets bit 6 of the interrupt control/status register high or low depending on whether
the user wants a PCI interrupt to be triggered by the falling or rising edge of INT_REQ.

7. If inputs are configured to latch, board firmware latches these input ports. (See bits 5 and 6 in

Table B-2.)

8. The interrupt-received status in board firmware causes interrupt-pending bit 17 of the inter­rupt control/status register to be set to logic high.

9. The interrupt-received status in board firmware causes a computer CPU interrupt to start,
stopping execution of the current CPU task.

10. Computer hardware detects an interrupt request signal and transfers control to an interrupt
service routine (ISR).

11. Computer software starts the ISR, which takes control of the CPU and starts processing the
KPCI-3160 input data.

12. The ISR proceeds.

13. Ideally, for a well-planned data acquisition session, both of the following conditions are met
while the ISR is in progress and the interrupt-pending bit is set:

• No new external interrupt requests occur during this time.

• If the board is set to detect both the rising and falling edges of an interrupt request signal,

AND the rising edge started the ISR, then the falling edge does not occur during this
time.

However if either or both of the above conditions are not met while the interrupt-pending bit
is set, the following occurs:

a. The rising and/or falling edges of interrupt signals have no effect; these interrupts are

missed.

.

KPCI-3160 User’s Manual I/O Address Mapping B-7

b. When the first rising or falling edge is missed, the problem is recorded as follows:

1. Board firmware detects the missed interrupt, causing interrupt-missed bit 23 of the
interrupt control/status register to be set to logic high.

2. Computer software, if appropriately programmed, detects that bit 23 has been set and
notifies the user of the missed interrupt.

c. If additional rising or falling edges are missed (edges 2, 3, ...., n), the problems are not

recorded, as follows:

1. No additional interrupt-missed bits are set (there is only one interrupt-missed bit).

2. Computer software cannot further notify the user.

14. The ISR, if appropriately programmed, writes ones (Acknowledge) to clear the interrupt­pending bit 17 and interrupt-missed bit 23 in the interrupt control/status register to logic low,
which clears interrupt-pending status and interrupt-missing status in board firmware.

15. The ISR, if appropriately programmed, clears the rising/falling edge of bit 6 in the interrupt
control/status register to logic low.

16. The ISR finishes.

17. The ISR dispatcher of the operating system detects that the ISR has finished and sends an
end-of-interrupt instruction to the CPU.

NOTE The end-of-ISR behavior depends on the operating system being used.

18. The CPU returns to the task that it was executing at the time of the interrupt.

19. At some point, the user circuit may disable interrupts and latching by setting INT_ENN to
logic high.

20. Board firmware detects that INT_ENN is high and rejects interrupt signals at INT_REQ.

B-8 I/O Address Mapping KPCI-3160 User’s Manual

Manipulating control and data registers

Be aware that software programming for a PCI board, such as the KPCI-3160, is more involved
than for an ISA board. As mentioned in the Appendix B introduction, DriverLINX eliminates the
need for user interaction with control and data registers. However, control and data registers can
be manipulated in the following special situations:

• You are an advanced user needing to use the KPCI-3160 with an operating system other than
Microsoft Windows 95/98 or Windows NT 4.0 or greater. In this situation, you must write a
new driver. This task requires an in-depth knowledge of PCI-bus interfacing and your devel­opment operating system.

• You want to program the KPCI-3160 at the register level using an ActiveX hosting language.
In this situation, you may use the “Direct I/O ActiveX Automation Object” that comes with
DriverLINX. The Direct I/O ActiveX Automation Object allows you to set the control and
data registers directly and bypass the DriverLINX API, yet avoids the full complexities of
PCI bus interfacing. Refer to your DriverLINX manual for more information.

• You want to reuse, with the KPCI-3160, an existing application program that makes port I/O
calls to an ISA-bus digital I/O board such as the PIO-96 or PIO-24. (If so, skip to “Using

existing port I/O software to manipulate control and data registers” at the end of
Appendix B.)

General approach to manipulating control and data registers

This subsection outlines some general program tasks needed to use the data and control registers
of the KPCI-3160 board.

The control registers must first be set by software statements to configure each group of A, B,
and C ports for the desired direction (input or output) and to prepare interrupt control/status bits.

• For register map A, port directions are set by writing to the combination data and control reg­isters located at BADDR1 + 0x0, BADDR1 + 0x4, BADDR1 + 0x8, and BADDR1 + 0xC
(where 0x designates hexadecimal).

• Use of register map B is not recommended or supported. Use only register map A.

• If the board is to transfer and process data upon receipt of external interrupts, the following

are set:
– Bit 12 of the interrupt control/status register, located at BADDR0 + 0x38, is set to 1 to

configure the board for interrupt service.

– The interrupt-pending bit and the interrupt missed bit in BADDR0 are initialized to the

cleared condition by writing 1s to interrupt control/status register status bits 17 and 23 at
BADDR0 + 38. The polarity select bit is initialized to the clear condition by writing a 0
to the interrupt control/status register control bit 6.

In most applications all eight data bits of each port will be set as either inputs or outputs. How­ever, the upper four bits and lower four bits of port C can be configured separately as either
inputs or outputs.

KPCI-3160 User’s Manual I/O Address Mapping B-9

Thereafter, data can be input to or output from the data registers.

• Data ports configured as outputs are set by writing ones and zeros to these registers with
software statements.

• Data ports configured as inputs are set by applying logical high and low signals to the input
terminals. These set values are retrieved by one of the following methods:

– The set input values are retrieved via polling or software commands if the KPCI-3106

I/O bits are configured as general-purpose I/O bits (no external interrupt service).

– The set input values are retrieved and processed via external interrupts if interrupt con-

trol/status-register bit 12 is set high. Refer to Section 4, “External Interrupts,” and to the
previous subsection, “Interrupt control/status register.”

• If you retrieve data using interrupts, the interrupt-pending bit and interrupt-missing bit must
be cleared by software at the conclusion of each interrupt-service (ISR) by writing ones
(Acknowledge) to interrupt control/status register bits 17 and 23 at base address 0 + 0x38.
The interrupt enable bit and interrupt polarity select bit of the interrupt control/status register
are cleared by writing zeros to bits 12 and 6.

Using existing port I/O software to manipulate control and data registers

If you have a port I/O application program that was designed to work with the industry-standard
8255 and 82C55 chips, you may be able to reuse it without program modifications—under Win­dows 95/98 only—as follows:

1. Leave the REG-MAP-SEL jumper unconnected (the default), so that the board operates in
the 8255/82C55 emulation mode under control and data register map A.

2. Using the Windows Device Manager, locate the Windows-assigned base address for your
board as follows:

a. Right-click the My Computer icon on your desktop.

b. On the menu that appears, click Properties.

c. On the System Properties dialog box that appears, click the Device Manager tab. The

Device Manager appears.

d. In the Device Manager look for a DriverLINX drivers item.

e. Under the DriverLINX drivers item, click the + sign to the left of this item.

A second level list should appear that includes the KPCI-3160 board.

f. Select the KPCI-3160 board.

g. Click on the Properties button. A Keithley KPCI-3160 Board Properties dialog box

appears.

h. In the Keithley KPCI-3160 Board Properties dialog box click the Resources tab. A

Resource Settings list appears.

i. In the Resource Settings list, two I/O space ranges should appear, each labeled Input/

Output Range. Record the starting address of the Input/Output Range that contains
32 bytes—typically the second of the two Input/Output Range ranges. This is the
BADDR1 base address. (Refer to “General PCI address assignments.”)

For example, if one Input/Output Range is FCC0 - FCFF and the other is
FCA0 - FCBF, then FCA0 is the BADDR1 base address, because:

(FCBF minus FCA0)

hex

= 1F

hex

= 31

(32 bytes, counting the base-address byte)

decimal

The other Input/Output Range, starting at BADDR0, always contains 64 bytes. Follow­ing the above example, (FCFF minus FCC0)

hex

= 31F

hex

= 63

decimal

.

B-10 I/O Address Mapping KPCI-3160 User’s Manual

3. In your existing application program, where you are asked to enter the base address of the
board, enter the BADDR1 base address that you found in step 2i (in place of the base address
that you would have manually assigned to an ISA board using a DIP switch).

4. Run your existing application program in Windows or DOS mode, as appropriate.

If your operating system is Window NT, you need to provide a special driver and probably need
to revise your existing port I/O application program before it can manipulate KPCI-3160 port
I/0. (You then find the needed PCI BIOS-assigned base address using Windows NT Diagnostics,
instead of the Windows 95/98 Device Manager). Keithley does not recommend or support such
efforts.
