KPXI-DIO80-900-01 Rev. A / January 2007

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.

Safety Precautions

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 Instruments products are designed for use with electrical signals that are rated Measurement Category I and
Measurement Category II, as described in the International Electrotechnical Commission (IEC) Standard IEC 60664. Most
measurement, control, and data I/O signals are Measurement Category I and must not be directly connected to mains voltage or
to voltage sources with high transient over-voltages. Measurement 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.

12/06

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.

If a screw 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 symbol on an instrument shows that the surface may be hot. Avoid personal contact to prevent burns.

The symbol indicates a connection terminal to the equipment frame.

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.

The KPXI-DIO-32-80M module is an ultra-high speed digital I/O module, which consists of 32
digital input or output channels. High performance designs and the state-of-the-art technology
make this module ideal for high speed digital input and output applications.

The module performs high-speed data transfers using bus mastering DMA and scatter/gather via
32-bit PCI bus architecture. The maximum data transfer rates can be up to 80MB per second. It is
very suitable for interface between high speed peripherals and your computer system.

The module is configured as two ports, PORTA and PORTB, each port controls 16 digital I/O lines.
The I/O can configure as either input or output, and 8-bit or 16-bit. Depending on the connected
device, users can configure it to meet many high speed digital I/O requirements.

There are 4 different digital I/O operation modes supported:

1. Internal Clock: the digital input and output operations are paced by internal clock and

transferred by bus mastering DMA.

2. External Clock: the digital input operation is paced by external strobe signal ( DIREQ )

and transferred by bus mastering DMA.

3. Handshaking: through REQ signal and ACK signal, the digital I/O data can have

simple handshaking data transfer.

4. Pattern Generation: You can output a digital pattern repeatedly at a predetermined

rate. The transfer rate is controlled by internal timer.

Introduction

This section contains information about handling and installing Keithley Instruments’ KIDAQ®
KPXI series modules:

• Handling precautions

• PCI configuration

• Installation

Handling precautions

CAUTION Use care when handling the KPXI series modules. The modules contain

electro-static sensitive components that can be easily damaged by static
electricity.

When handling, make sure to observe the following guidelines:

• Only handle the module on a grounded anti-static mat.

• Wear an an anti-static wristband that is grounded at the same point as the anti-static mat.

PCI configuration

Plug-and-play

The Interrupt and I/O port address are the variables associated with automatic configuration, the
resource allocation is managed by the system BIOS. Upon system power-on, the internal
configuration registers on the board interact with the BIOS. As a plug-and-play component, the
board requests an interrupt number via its PCI controller. The system BIOS responds with an
interrupt assignment based on the board information and system parameters. These system
parameters are determined by the installed drivers and the hardware load recognized by the
system. If this is the first time a KIDAQ
system, a hardware driver needs to be installed. Refer to

Configuration

Configuration is done on a board-by-board basis for all PXI boards on your system. Configuration
is controlled by the system and software. There is no jumper setting required (or available) for
base address, DMA, and interrupt IRQ.

The configuration is not static, but is subject to change with every boot of the system as new
boards are added or removed.

Troubleshooting

If your system doesn't boot or if you experience erratic operation with your PXI board in place, it's
likely caused by an interrupt conflict (perhaps the BIOS Setup is incorrectly configured). In
general, the solution, is to consult the BIOS documentation that comes with your system.

NOTE For best module performance, install the module in a PXI slot that provides bus-

mastering capability.

KPXI Ultra-High Speed DIO Card User’s Manual Section 2: Installation

Installation

Step 1. Install driver software

Windows® will find the new module automatically. If this is the first time a KPXI series digital I/O
module has been installed, a hardware driver needs to be installed. Use the following installation
procedure as a guide.

NOTE Keithley Instruments controllers are pre-loaded with the necessary drivers.

For Windows XP/2000:

1. Insert the CD shipped with the module. The CD should auto load. From the base menu
install the KDIO-DRVR. This is the hardware driver that recognizes the KPXI series
modules. If the CD does not auto load run, then under x:\KDIO-DRVR\DISK1\, you will find
SETUP.EXE (x is the drive letter of your CDROM). This will run the CD menu. On the CD
menu, click the driver for your model to install.

2. When you complete driver installation, turn off the system.

Step 2. Inspect the module

Keeping the “Handling precautions” information in mind, inspect the module for damage. With the
module placed on a firm flat surface, press down on all socketed IC's to make sure that they are
properly seated.

If the module does not pass the inspection, do not proceed with the installation.

CAUTION Do not apply power to the module if it has been damaged.

The module is now ready for installation.

Step 3. Install the module

Remove power from the system and install the KPXI card in an available slot.

The PXI connectors are rigid and require careful handling when inserted and removed. Improper
handling of modules can easily damage the backplane.

To insert the module into a PXI chassis, use the following procedure as a guide:

1. Turn off the system.

2. Align the module's edge with the card guide in the PXI chassis.

3. Slide the module into the chassis until resistance is felt from the PXI connector.

4. Push the ejector upwards and fully insert the module into the chassis. Once inserted, a
"click" can be heard from the ejector latch.

5. Tighten the screw on the front panel.

6. Turn on the system.

To remove a module from a PXI chassis, use the following procedure as a guide:

1. Turn off the system.

2. Loosen the screw on the front panel.

3. Push the ejector downwards and carefully remove the module from the chassis.

Step 4. Verify installation

When the system is turned on for the first time with a new module present (or a module in a new
slot), Windows Add New Hardware Wizard attempts to locate the correct driver. If it cannot find
the correct driver, even after you have loaded the driver above in Step 1, then force the Add New
Hardware Wizard to look in Windows system32 directory. The driver files should be in this
location. If they are not, shutdown the system, remove the module, and restart the installation
process.

When the Add New Hardware Wizard finishes, the window will verify whether or not installation
was successful. To confirm if the module is installed correctly at a later time, use Windows Device
Manager. In the Device Manager under KIDAQ Boards, look for a device name matching the
model number of the newly installed board (see
installation is complete. If the board appears with a exclamation point or warning in Device
Manager, the installation was unsuccessful. If unsuccessful, use Device Manager to update the

Wiring and Termination

Transmission line effects and environment noise, particularly on clock and control lines, can lead
to incorrect data transfers if you do not take care when running signal wires to and from the
devices.

Take the following precautions to ensure a uniform transformation line and minimize noise pickup:

1. Use twisted-pair wires to connect digital I/O signals to the device. Twist each digital I/O sig­nal with a GND line.

2. Place a shield around the wires connecting digital I/O signal to device.

3. Route signals to the devices carefully. Keep cabling away from noise sources, such as
video monitor.

For KPXI-DIO-32-80M, it is important to terminate your cable properly to reduce or eliminate signal
reflections in the cable. This module supports active terminator on board. You can enable or
disable the terminator by software selection. This is a good way to include termination on the
signal transmission.

Additional recommendations apply for all signal connections to your KPXI-DIO-32-80M, and are
listed as follows:

1. Separate KPXI-DIO-32-80M device signal lines from high-current or high-voltage line.
These lines are capable of inducing currents in or voltages on the KPXI-DIO-32-80M if they
run in parallel paths at a close distance. To reduce the magnetic coupling between lines,

KPXI-DIO80-900-01 Rev. A / January 2007 Return to Section Topics 3-3

Section 3: Connection and Operation KPXI Ultra-High Speed DIO Card User’s Manual

separate them by a reasonable distance if they run in parallel, or run the lines at right angles
to each other.

2. Do not run signal lines through conduits that also contain power lines.

3. Protect signal lines from magnetic fields.

Operation

This section provides the detailed operation information for the KPXI-DIO-32-80M, including I/O
configuration, block diagram, input/output FIFO, bus-mastering DMA, scatter/gather, clocking
mode, starting mode, termination, I/O transfer mode, and auxiliary digital I/O.

Configuration
