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.

Interface software

DriverLINX interface software provides convenient interfaces for configuring and setting I/O
bits without register-level programming. DriverLINX also allows the user to run a custom pro­gram in Visual C/C++, Visual Basic, or Delphi.

TestPoint and LabVIEW are full-featured graphical data acquisition software packages that
work well with KPCI-3130 Series boards.

A summary of the pros and cons of using integrated packages (such as TestPoint or LabVIEW)
rather than writing custom programs (using DriverLINX) is provided in the Keithley Full Line
Catalog.

The KPCI-3130 Series has fully functional driver support for use under Windows 95/98/NT/2000.

NOTE DriverLINX drivers must be installed to run any applications for the

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

DriverLINX for Windows 95/98/NT/2000

DriverLINX Application Program Interface (API) software is supplied by Keithley with the
KPCI-3130 Series board. DriverLINX is essentially hardware independent. Its portable APIs
work across various operating systems, eliminating the need for additional programming when
changing operating system platforms.

In addition, 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. The software includes memory and data buffer management,
event triggering, extensive error checking, and context sensitive online help.

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

In addition to basic I/O support, DriverLINX provides:

• Built-in capabilities to handle memory and data buffer management.

• A selection of starting and stopping trigger events, including pre-triggering, mid-point

triggering and post-triggering protocols.

• Extensive error checking.

• Context-sensitive on-line help system.

Refer to the DriverLINX documentation to determine which services are supported by the
KPCI-3130 Series boards.

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-and­drop interface can be used to create data acquisition applications, without programming, for
IEEE-488 instruments, data acquisition boards, and RS232/RS485 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-3130 Series
boards.

Installation

3-2 Installation KPCI-3130 Series User’s Manual

Overview

This section provides instructions for the following procedures:

• Installing the software (DriverLINX drivers and interface software).

• Installing KPCI-3130 Series boards into the system.

• Configuring the installed software and board.

NOTE The KPCI-3130 hardware is designed to be installed after the device

drivers are installed. Be sure to install the DriverLINX software before
installing the KPCI-3130 board.

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.

Installing application software and drivers

Installing the TestPoint support

It is anticipated that, in the future, TestPoint will implicitly support the KPCI-3130 Series boards
without installing additional drivers. Check with the following concerning current availability of
TestPoint support for the KPCI-3130 Series:

• 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-3130 Series 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.

KPCI-3130 Series User’s Manual Installation 3-3

Installing the KPCI-3130 Series boards

This subsection helps you to do the following:

• Prepare 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 the 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.

Checking resources for the board

Ensure that your computer has sufficient resources, particularly power resources, to run your
KPCI-3130 Series 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.

Unwrapping and inspecting the board

NOTE Install the DriverLINX software before installing a KPCI-3130 Series

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

After you remove the wrapped board from its outer shipping carton, unwrap it 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 wrist strap. A grounded wrist strap discharges
static electricity from the wrapped board as soon as you hold it. Keep the wrist strap on until
you have finished installing the board.

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

3. Inspect the board for damage. If damage is apparent, arrange to return the board to the fac­tory. Refer to Appendix B, “Technical support.”

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

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

Connecting interface accessories

CAUTION The two I/O connectors of the KPCI-3130 board, labeled “Analog”

and “Digital”, are mechanically identical. Ensure that you connect
interface accessories, and, indirectly, external circuits to the correct
I/O connector. Connecting interface accessories or external circuits
to the wrong connector may result in damage to the KPCI-3130
board, the host computer, your external circuits, or all three.

The STP-36 accessory provides basic screw terminal wiring to the I/O connector of a
KPCI-3130 Series board. All of the screw terminals are connected to the same-numbered pins of
a KPCI-3130 “Analog” or “Digital” I/O connector. Figure 4-3 shows how the accessory con­nects to the KPCI-3130 or KPCI-3132.

Wiring I/O to external circuits

Wiring analog output signals

This section provides a few guidelines for wiring the analog outputs from the DACs (digital-to­analog converters) that are available on the KPCI-3130 Series boards. Each DAC can be
configured to output a range of ±10V. Performance characteristics and drive capabilities for
these DACs are listed in Appendix A. Eight DACs are available on the KPCI-3130 while two
DACs are available on the KPCI-3132.

WARNING Do NOT intersperse data acquisition connections with AC line con-

nections. Keep data acquisition cables and connections away from
any AC line connections. Interconnections or shorting between data
and power lines can result in personal injury or death or extensive
damage to your computer. To prevent this problem, ensure that all
connections are tight and sound, so that signal wires are unlikely to
come loose and short to hazardous voltages.

Ensure that there is not a short circuit at the output for any length of
time; maintaining a short circuit at the output causes the board to
become very hot and may result in personal injury.

CAUTION Ensure that both the computer and 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 circuit.

NOTE

Make all analog output connections to the “Analog” I/O connector of the board through the
screw terminals of an STP-36 screw terminal accessory. To connect an STP-36 accessory to your
board, refer to “Connecting interface accessories” earlier in this section. The appropriate STP-36
screw terminals are identified in Figure 4-1.

Avoid large capacitive loads at the analog outputs. Capacitive loads
higher than 100µF destabilize the analog outputs and make them sus­ceptible to ringing (transient oscillations).

KPCI-3130 Series boards contain separate ground connections for ana­log and digital signals. Use the analog ground (GND) for analog sig­nals and analog power; use the digital ground (DGND) for digital
signals and other power supply returns. Do this to avoid interference
from digital switching noise currents on sensitive analog signals. How­ever, be aware that both analog and digital grounds are tied together at
the board PCI connector and are ultimately connected to the building
system ground via the mains.

4-8 Connecting the Hardware KPCI-3130 Series User’s Manual

Making two-wire and four-wire mode connections

The KPCI-3130 Series can be configured for two-wire (local sense) or four-wire (remote sense)
mode connections. The selected mode determines whether the KPCI-3130 Series eliminates
voltage drops due to the lead wire resistance between the STP-36 and the load terminals.

NOTE

The STP-36 Screw Terminal accessory interfaces the KPCI-3130 Series
analog connector to screw terminals that are numbered identically to
the pins.

Two-wire mode (local sense)

For two-wire mode connections, the KPCI-3130 Series boards sense at the channel output and
the channel ground at the terminals of the STP-36.

Two jumpers are required for connections in the two-wire mode. As shown in Figure 4-4, one
jumper is placed between Sense High and Channel Output. Another jumper is placed between
Sense Low and Channel Ground. Failure to install both of these jumpers for each channel will
result in an alarm flag for the specific channel and an overvoltage on the channel’s output if the
channel is enabled. See Figure 4-5 for an example schematic.

For example, to configure CH0 for two-wire mode:

1. Install a jumper between pins 1 and 2 of the STP-36.

2. Install a jumper between pins 19 and 20 of the STP-36.

3. Connect the load between pins 1 and 19 or pins 2 and 20 of the STP-36.

NOTE

Terminate all unused channel sense lines (Sense HI to Output and Sense
LO to GND/return).

Four-wire mode (remote sense)

For four-wire mode connections, the Sense High and Sense Low wires are connected between
the STP-36 and the load terminal, eliminating voltage drops due to lead (wire) resistance. The
desired output voltage appears at the load terminals. See Figure 4-6 and Figure 4-7.

Note that for four-wire mode connections, there should not be any jumpers installed at the
STP-36 terminals.

For example, to configure CH0 for four-wire mode:

1. Connect the load between pins 1 and 19 of the STP-36.

2. Connect Sense High (pin 2 of the STP-36) to the (+) terminal of the load.

3. Connect Sense Low (pin 20 of the STP-36) to the (-) terminal of the load.

Overload detection

Each DAC features an overload protection circuit that monitors inaccuracies in the potential
range of the DAC. Overload detection occurs when one or more of the following conditions
exist:

Nothing is connected to the Analog I/O Connector.

An accessory board is connected to the Analog I/O Connector; however, the accessory board
is not connected for two-wire or four-wire sensing.

The Analog I/O Connector is connected for two-wire or four-wire sensing but the wiring is
incorrect or there is a missing or bad connection.

There is a voltage output discrepancy due to a short circuit.

Use the following procedure to determine if an overload condition exists on a DAC:

1. Open the AIO Test Panel.

2. Click on the DIO tab.

3. On the Input Panel, select Channel 4. An overload is indicated by a one in the applicable bit
(bit 7 represents DAC7, bit 6 represents DAC6, etc.).

If applicable, clear the overload(s) by writing a “1” to the appropriate Channel 4 bit(s).

Wiring digital input and output signals (KPCI-3130 only)

This section provides a few guidelines for wiring Digital I/O signals that are available on the
KPCI-3130 board.

WARNING Do NOT connect data acquisition inputs to the AC line. Keep data

acquisition cables and connections away from any AC line
connections. Interconnections or shorting between data and power
lines can result in personal injury or death or extensive damage to
your computer.

CAUTION Ensure that both the computer and 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 circuit.

NOTE

KPCI-3130 boards contain separate ground connections for analog and
digital signals. Use the analog ground (GND) for analog signals and
analog power; use the digital ground (DGND) for digital signals and
other power supply returns. Do this to avoid interference from digital
switching noise currents on sensitive analog signals. However, be aware
that both analog and digital grounds are tied together at the board PCI
connector and are ultimately connected to the building system ground
via the mains.

Monitoring contact closure at an input

To ensure that the KPCI-3130 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 4-8.

Eliminating contact bounce at an input

The effects of contact bounce may be eliminated by programming in the 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-3130 input. Figure 4-9 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.

Drawing excessive current may damage the KPCI-3130 board and,
potentially, the computer.

The board extends fuse-protected power from the +5VDC computer supply to the I/O connector.
This power is convenient for use in light external circuits, such as pull-up resistors. If the condi­tions noted in the above CAUTION are maintained, this power may also be used to energize

Calibration

5-2 Calibration KPCI-3130 Series User’s Manual

Introduction

The KPCI-3130 Series board was initially calibrated at the factory. Keithley advises that the cal­ibration is checked every six months and the board re-calibrated when necessary. This section
provides KPCI-3130 Series calibration information.

Objectives

This procedure calibrates the analog outputs by attempting to independently zero the offset and
adjust the gain for each of the digital-to-analog converters (DACs) on the KPCI-3130 Series
board.

Calibration summary

Analog outputs are calibrated using a DVM/DMM, and the DriverLINX Calibration Utility.
(The DriverLINX Calibration Utility is installed when the DriverLINX software is installed.)

NOTE KPCI-3130 Series calibration is accomplished by adjusting two internal

registers inside the DAC through the Calibration Utility software. Con­nection to the board test points is via a screw terminal accessory con­nected to the I/O connector. There are no calibration potentiometers to
adjust or test points to monitor.

Equipment

The DAC calibration values are stored in on-board nonvolatile RAM (NVRAM), which retains
its contents even when the board is unpowered. During bootup (only), DriverLINX reads these
values and stores them in the DAC’s internal offset and gain registers.

The following equipment is needed to calibrate the KPCI-3130 Series board:

• A digital voltmeter (DVM) or digital multimeter (DMM) accurate to 6½ digits, such as a
Keithley Model 2000.

• An STP-36 screw terminal accessory to make analog connections to the board.

• A Keithley CAB-1284CC series cable or a standard IEEE-1284 Type C-C mini-Centronics

cable to connect the screw terminal accessory to the “Analog” I/O connector of the
KPCI-3130 Series board. To achieve factory calibration results, use a cable length of
2 meters.

KPCI-3130 Series User’s Manual Calibration 5-3

Calibration procedure

This section describes the steps required to calibrate the analog outputs of the KPCI-3130 Series
board.

Preparing for the calibration

Prepare the system for calibration as follows:

1. Warm up the DVM/DMM.

2. Turn OFF the host computer.

3. Set up STP-36 screw terminal accessory with all channels sense lines (even unused)
configured.

4. Connect the STP-36 screw terminal accessory to the KPCI-3130 Series board.

5. Turn ON the host computer.

6. Allow 20 minutes for the system (board) to warm up.

7. Start the calibration utility as follows:
a. Click on the Windows Start tab.

b. In the Start menu, click Programs.

c. Find the DriverLINX folder and click the Test Panels → KPCI-3130 Calibration

Utility entry. The Select DriverLINX Device dialog box appears.

d. In the Select DriverLINX Device dialog box, select the device number for the board and

click OK. The KPCI-3130 Calibration Utility dialog box appears.

Calibrating the analog outputs

The KPCI-3130 Series boards have independent analog outputs provided by digital-to-analog
converters (DACs or D/A converters). In this part of the procedure, offset and gain adjustments
for the DACs are made. Do the following:

NOTE The KPCI-3130 has eight analog outputs (and 8 DACs) while the

KPCI-3132 has two analog outputs (and 2 DACs).

1. In the KPCI-3130 Calibration Utility dialog box, click the D/A Calibration tab. The D/A

Calibration dialog box appears.

2. Refer to DriverLINX’s on-line help for a detailed description of the Calibration Utility.

3. If none of the board(s) removed in step 1 appear damaged, check for host computer malfunc­tions, as follows:

a. Place the board(s) removed in step 1 in an electrostatically safe location. Do not reinstall

them at this time.

b. Turn ON power to the host computer.

c. Perform system diagnostics as required to determine if the computer hardware and oper-

ating system are functioning properly.

4. If the computer or operating system malfunctions in step 3:

a. Determine the cause of the computer hardware or operating system malfunctions.

b. Fix the computer hardware or operating system malfunctions.

c. Go to “Problem isolation Scheme G: verification of problem solution.”

5. If the host computer seems to be operating on its own without problems, locate a KPCI-3130
Series board that is known to work properly.

NOTE If a working KPCI-3130 Series board is not available, refer to the

instructions in “Technical support” and contact Keithley for help in iso-
lating the cause of the problem.

B-4 Advanced Troubleshooting KPCI-3130 Series User’s Manual

6. Determine the PCI resources detected by the computer, as follows:

a. Shut down Windows 95/98/2000/NT and turn OFF power to the host computer.

b. Insert a blank diskette, or any unbootable diskette, into the A: drive.

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

d. The boot cycle stalls at a text screen listing system characteristics and resources with the

following message displayed at the bottom of the screen: Non-system disk or disk error.
Replace and press any key when ready.

NOTE Having an unbootable diskette in the A: drive automatically pauses the

boot cycle at the system characteristics and resources screen. Another
method of pausing the boot cycle (e.g., pressing the PAUSE key) may be
used.

e. Note and record the displayed PCI device listing… (If a printer is attached to the system,

press the PRINT SCREEN key to print a copy of the screen.)

f. Remove the diskette, press any key, and allow the boot cycle to finish.

7. Install the known good KPCI-3130 Series board into the system, as follows:

a. Shut down Windows 95/98/NT/2000 and turn OFF power to the host computer.

b. Install the known good KPCI-3130 Series board in the slot from which the potentially

faulty board was removed in step 1. Refer to Section 3, “Installing the KPCI-3130 Series

boards,” for board installation instructions.

NOTE The purpose of this step is to verify that the PCI slot from which the sus-

pect board(s) was removed is not faulty. One slot is verified at a time;
therefore, if more than one board was removed in Step 1, this step will
need to be repeated (Step 8).

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

8. Repeat Step 5 to determine the PCI resources detected by the computer with the KPCI-3130
Series board installed. Windows 95 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 board is installed are in good condition.

• The board is seated properly in the expansion slot.

9. If more than one KPCI-3130 Series board was removed (from other PCI slots) in step 1,
repeat steps 6 and 7 with the good board installed in each of the other slots.

10. If the good board is recognized as a PCI component in each slot tested, the PCI slot(s) can be
eliminated as the cause of the problem. Go to “Problem isolation Scheme B: installation” to
verify DriverLINX installation and board configuration.

11. If the good board is not recognized as a PCI component in one of the slots tested, the PCI
slot connector may be causing the problem. Go to “Problem isolation Scheme D: expansion

slot connectors.”

11. Reinstall the board(s), as follows:

CAUTION Wear a grounded wrist strap to avoid electrostatic damage to the

board. Do not touch board components or conductors when han­dling the board.

NOTE If Scheme B is being performed independently as an installation check,

reinstall all boards removed in step 9. If Scheme B is being performed as
part of the systematic problem isolation procedure, reinstall only the
known good board (refer to Scheme A).

a. Shut down and turn OFF the computer.

b. Install the board(s) in its expansion slot(s) using the procedure outlined in Section 3,

“Installing the KPCI-3130 Series boards.”

c. Turn ON and reboot the computer.

d. Configure the board and software using the procedure outlined in Section 3,

“Configuring the software and board.”

e. Return to step 1 and run the installation check again.

12. DriverLINX and the KPCI-3130 Series board(s) are installed correctly.

a. If starting the I/O panel was performed as an installation check, return to Section 4 and

finish installing the data acquisition system, starting with Section 4, “Identifying I/O con-

nector pin assignments for KPCI-3130 Series.”

b. If starting the I/O panel was performed as part of the systematic problem isolation proce-

dure AND the board has been reconfigured and/or DriverLINX has been re-installed, go
to “Problem isolation Scheme G: verification of problem solution.”

c. If starting the I/O panel was performed as part of the systematic problem isolation proce-

dure AND the board and DriverLINX software were not re-configured or re-installed to
allow the test panel to start, then the problem must lie elsewhere. Go to “Problem isola-

tion Scheme C: application software” to check for application software issues.

Scheme C:

• Checks custom application software source code.

• Checks compatibility and installation of commercial application software.

A flow chart is provided in Figure B-6.

NOTE The known good board installed in Scheme A should still be installed.

This eliminates possible board I/O problems during Scheme C.

NOTE This is not a stand-alone procedure and should only be used when called

for by another procedure.

1. Perform the procedure outlined in the “Analog output software test” found later in this
Appendix.

NOTE If the software appears not to be working properly with the analog out-

puts, go to step 4.

2. Perform the procedure outlined in the “General-purpose digital I/O software test (KPCI-

3130 only)” found later in this Appendix.

NOTE If the software appears not to be working properly with the digital I/O,

go to step 4.

3. If the software appears to be working with both the analog outputs (3130 Series) and the
digital I/O (KPCI-3130 board only), go to “Problem isolation Scheme E: user wiring” and
check the external connections.

4. If the applications program is a proven program (i.e., a commercial program that cannot be
modified), the software may be installed incorrectly or may be incompatible with Driver­LINX. Contact the program manufacturer and verify that the current version of the program
is installed, that it is installed correctly, and that it is compatible with DriverLINX.

a. If the program is the current version and is installed correctly and is compatible with

DriverLINX, refer to “Technical support” and contact Keithley.

b. If the program is not the current version or is not installed correctly:

1. Correct program installation as required.

2. Repeat the “Analog output software test” and the “General-purpose digital I/O

software test (KPCI-3130 only)” found later in this Appendix.

3. If the software appears to be working, go to Scheme G to verify the problem solution.

4. If the software still does not work, refer to “Technical support” and contact Keithley.

5. If the applications program is a custom program that can be modified:

a. Check and debug the source code as necessary.

b. Repeat the “Analog output software test” and the “General-purpose digital I/O software

test (KPCI-3130 only)” found later in this Appendix.

KPCI-3130 Series User’s Manual Advanced Troubleshooting B-19

Specified hardware I/O tests

The tests in this section check performance of the KPCI-3130 Series board’s analog and also the
KPCI-3130’s digital I/O.

The tests use proven DriverLINX utilities, thereby bypassing any unresolved application soft­ware issues.

These tests are intended to be used when specified in the preceding “Systematic problem isola-

tion” procedure. However, they may also be used at any time for general functional checks of the

KPCI-3130 Series board.

NOTE During these tests, disconnect all user circuits from the board, except as

specified in individual test procedures.

Analog output hardware test

The analog output test checks whether the digital-to-analog converters (DACs) of the board are
working correctly. Zero voltages are set at the analog outputs, using the on-screen level control
utility supplied with DriverLINX. The two output voltages are then measured with a digital volt­meter to verify reasonable DAC offsets. Similarly, a mid-range voltage is set for each of the ana­log outputs and the procedure is repeated to verify proper digital to analog conversion.

NOTE During this test, ensure that no user circuits are connected to the

KPCI-3130 Series board, via the required screw terminal accessory,
except for analog output connections specified for the test.

The analog output test is primarily a functional test, not a calibration
check, although measured outputs from a properly calibrated board
should correspond to DAC settings, within the accuracy specifications of
the board. To check and adjust accuracy, refer to Section 5,
“Calibration.”

Equipment

The following equipment is required to perform the analog output test:

• A Digital Voltmeter (DVM) or a Digital Multimeter (DMM) set to the 10V range.

• An STP-36 screw terminal accessory, to which the DVM/DMM is connected as indicated

in Table B-1.

NOTE If possible, use a screw terminal accessory that is reserved for I/O tests.

Using the screw terminal accessory normally connected to the external
circuits may lead to potential wiring errors involved in disconnecting
and later reconnecting the external circuits.

• Using a DriverLINX graphical interface, configure the channel 0 and 1 bits as outputs and

the channel 2 and 3 bits as inputs.

• Using the same DriverLINX graphical interface, set the channel 0 and 1 outputs in a particu-

lar bit pattern and check channels 2 and 3 inputs for the same bit pattern. Repeat, using a sec­ond bit pattern.

The digital I/O of the board is performing satisfactorily if all bits respond appropriately. The
specified bit patterns check both for direct ON/OFF response and for shorts between bits.

Equipment

All I/O is set and read using the DriverLINX Digital Input/Output test panel; no instruments are
required. However, an STP-36 screw terminal accessory must be wired in the loop-back config­uration shown in Figure B-14.

NOTE If possible, use a screw terminal accessory that is reserved for I/O tests.

Using the screw terminal accessory normally connected to the external
circuits may lead to potential wiring errors involved in disconnecting
and later reconnecting the external circuit.

Procedure

1. Turn OFF the host computer.

2. If a screw terminal accessory is attached to the upper “Analog” I/O connector of the

On-screen digital I/O controller

KPCI-3130 Series User’s Manual Advanced Troubleshooting B-27

NOTE The on-screen digital I/O controller works as follows:

• Channel 0 refers to the twelve multi-function digital I/O bits. These

bits may be manipulated with the digital I/O controller only when the
multi-function bits are configured as general-purpose bits.

• Channels 1 to 4 refer to the four 8-bit general-purpose registers in

the KPCI-3130. Bits displayed on the Digital Input Panel and the
Digital Output Panel are numbered 0-7 for every channel—instead
of 0-7 for channel 0, 8-15 for channel 1, 16-23 for channel 2, and
24-31 for channel 3 as for the KPCI-3130 “Digital” I/O connector.
Refer to Table B-4.

• Invalid channels and settings appear as dark gray squares. For

example:

– Non-existent channels always appear as dark gray squares.

– In the Digital I/O Configuration Panel, Channel 0, corresponding to the

twelve multi-function digital I/O bits, appears as dark gray squares. The
configuration of the twelve bits is fixed; six are always inputs and six are
always outputs.

• Valid channels and settings appear as white squares when OFF and

green squares when ON. (When the manual is printed in black and
white, valid channels and settings appear as white squares when
OFF and as light gray squares when ON).

• The two-digit numeric displays under Input Bits and Output Bits

show the hexadecimal values of the adjacent bit patterns.

• To configure a valid channel either for input or output, use the

Digital Channel Configuration Panel. Click on either the Input or
Output square below the channel number.

• To turn ON output-channel bits, use the Digital Output Panel. First

select the channel number of the bits to be turned ON by clicking on
the appropriate square under Channels. Then, turn ON a bit by
clicking the appropriate square under Output Bits. Turn OFF a bit
in the same way.

• To read an input-channel bit, use the Digital Input Panel. First

select the channel number to be checked by clicking the appropriate
square under Channels. Then, read the numbered bit under Input
Bits. OFF input bits appear as black dots and ON input bits appear
as green dots. (When the manual is printed in black and white, OFF
input bits appear as black dots and ON input bits appear as light
gray dots.)

NOTE When the multi-function bits are configured as general-purpose bits, a

similar test of the twelve multi-function digital I/O bits can be performed
with the on-screen digital I/O controller. Wire loop-back connections at
an STP-36 accessory between same-numbered input and output bits. (If
the outputs are always wired only to inputs, no protective series resistors
are required. If two output bits are wired together and both are turned
ON without adequate current limiting, damage will result.) Turn input
bits 0, 2, and 4 ON and look for an identical output bit pattern. Repeat,
turning input bits 1, 3, and 5 ON.

Specified software I/O tests

The tests in this section check whether the application software correctly performs analog and
digital I/O tasks. The I/O are tested using a KPCI-3130 Series board known to work properly,
thereby bypassing potential board problems. These tests are intended to be used when specified
in the preceding “Systematic problem isolation” procedure.

NOTE During these tests, disconnect all user circuits from the board, except for

connections specified in individual test procedures.

Analog output software test

This basic analog output test checks whether the application software correctly sets direct cur­rent (DC) analog output voltages. Zero volts is set at the analog outputs, using the application
software. The output voltages are then measured with a digital voltmeter to verify reasonable
DAC offsets. Similarly, a mid-range voltage is set for each of the analog outputs and the proce­dure is repeated.

NOTE During this test, ensure that no user circuits are connected to the

KPCI-3130 Series board, via the required screw terminal accessory,
except for analog output connections specified for the test.

The analog output software test is a software function test, not a
calibration check. To check and adjust the accuracy, refer to Section 5,
“Calibration.”

The analog output software test is only a basic check of the application
software.

B-30 Advanced Troubleshooting KPCI-3130 Series User’s Manual

Equipment

The following equipment is required to perform the analog output test:

• A Digital Voltmeter (DVM) or a Digital Multimeter (DMM) set to the 10V range.

• An STP-36 screw terminal accessory, to which the DVM/DMM is connected as indicated in

Table B-5.

NOTE If possible, use a screw terminal accessory that is reserved for I/O tests.

Using the screw terminal accessory normally connected to the external
circuits may lead to potential wiring errors involved in disconnecting
and later reconnecting the external circuit.

Target mode

A PCI bus mode in which data from a data acquisition board is transferred indirectly to the
computer memory in the foreground, via the host computer CPU, instead of directly, via Bus
mastering. Sometimes referred to as pass-through operation. See also bus mastering and
foreground task.

Trap

(verb)

To intercept an action or event before it occurs, usually in order to do something else.

TTL

Abbreviation for transistor-transistor-logic. A popular logic circuit family that uses multiple­emitter transistors. A low signal state is defined as a signal 0.8V and below. A high signal state is
defined as a signal +2.0V and above.
