Configuring the KPCI-3140 Series
Introduction
The installation program provides general instructions for installing and configuring
DriverLINX. This manual explains the steps and special features that apply to
Keithley’s KPCI-3140 Series boards.
Installing and configuring DriverLINX for a Keithley KPCI-3140 Series board
requires three steps:
1. Install DriverLINX. Follow the instruct ions given by the installation
program. The Read Me First instructions explain the components and
drivers you can install.
2. Configure DriverLINX. This creates a Logical Device, which stores
configuration information for your board. See “Configure DriverLINX
Device Dialog” on page 12 for configuration options specific to a
Keithley KPCI-3140 Series model.
Windows NT
3. Install your KPCI-3140 hardware. Follow the instructions in your
hardware man ua l.
After configuring DriverLINX, insta l ling your b oard and rest arting Windo ws, reopen
the DriverLINX Configuration Panel to make sure that DriverLINX loaded the
Logical Device for your board. If the Logical Device is not loaded, the Event Log
may have a message from the driver that explains why. You can check the Event Log
using the DriverLINX Event Viewer on the Windows Start Menu.
Under Windows NT 4.0, a Logical Device may not load because the operating
system does not always configure Plug-and-Play PCI devices properly. To work
around this , set your computer’s BIOS to config ure Plug-and-Play devices before it
starts the operating system. On various computers the BIOS setting is called “Plugand-Play Aware OS – Disabled” or “Plug & Play OS – No”.

Configure DriverLINX Device Dialog
DriverLINX uses a standardized configuration protocol for all data-acquisitio n
hardware. Configuration assigns an identifying device number to a specific KPCI3140 Series board in your computer and allows you to enable or disable bus
mastering.
The installation program automatically starts the DriverLINX Configuration Panel.
To start it now, use the shortcut on the Windows Start Menu.
When you click the Configure… button on the DriverLINX Configuration Panel,
DriverLINX displays the Configure DriverLINX Device dialog. The dialog has a
page for each subsystem on the Keithley KPCI-3140 Series. The following sections
describe your choices in configuring DriverLINX to work with your board.

Windows 95 automatically determines the model of your board so DriverLINX
disables Model selection.
Board Id
The KPCI-3140 Series boards do not have unique serial numbers that DriverLINX
can use to match a Logical Device to a board while loading the driver. Under
Windows 95/98, DriverLINX can match a Logical Device to a board based on the
bus slot. Under Windows NT, DriverLINX matches Logical Devices in the sequence
that Windows enumerates them on the bus.

KPCI-3140 Series Hardware Features
The KPCI-3140 Series offers your data-acquisition application a wide variety of
useful features. Digital I/O ports support pre- and post-triggering. Eight of the
counter/timers are user-accessible. DriverLINX accesses these features through its
hardware independent Applications Programming Interface (API).
The following table is a cross-reference between hardware features and the
DriverLINX features that access them.

DriverLINX Hardware Model for KPCI-3140 Series
DriverLINX provides a portable, hardware-independent API for data-acquisition
boards while still allowing applications to access unique or proprietary hardware
features of specific products. To achieve this goal, DriverLINX maps a hardwareindependent, or abstract, data-acquisition model onto KPCI-3140 Series hardware
capabilities.
The following sections describe how DriverLINX implements KPCI-3140 Series
hardware features as Subsyste ms, Modes, Operations, Events, Logical Channels,
Buffers, and Messages.
DriverLINX Subsystems
The KPCI-3140 Series supports the following DriverLINX subsystems:
1. Device—refers to a KPCI-3140 Series board as a whole.
2. Digital Input—refers to the digital input ports as well as 1-bit digital
control signals and external clock inputs.
3. Digital Output—refers to the digital output ports.
4. Counter/Timer—refers to the onboard counter/timer channels for
pacing digital input/output or performing measuring and waveform
generation functions.
DriverLINX Modes
Applications use modes in Service Requests to advise DriverLINX on their preferred
hardware data transfer technique. The DriverLINX modes fall into two general
classes:
• Foreground or synchronous modes. The calling application does not
regain control until DriverLINX completes the Service Request.
DriverLINX supports this mode for simple, single value I/O operations
or software housekeeping functions that DriverLINX can complete
without a significant delay.
20 • Using the KPCI-3140 Series with DriverLINX Using DriverLINX with Your Keithley KPCI-3140 Series
• Background or asynchronous mo des. The calling application regains
control as soon as DriverLINX initiates the task. The calling
application must synchronize with the data-acquisition task using status
polling or DriverLINX’s messages (preferred). DriverLINX supports
this mode for buffered data transfers or for commands that require a
significant time to complete.
DriverLINX supports four modes with the KPCI-3140 Series for its commands
(Service Requests).
• Polled Mode—This is a foreground or synchronous operation.
DriverLINX supports this mode for simple, single-value I/O operations
that the data-acquisition board can complete without significant delay.
• Interrupt Mode—This is a background or asynchronous operation.
DriverLINX transfers data between the computer’s memory and the
data-acquisition board using hardware interrupts and programmed I/O
transfers.
• Other Mode—This is a foreground or synchronous operation.
DriverLINX supports this mode for initialization, configuration,
calibration, data conversion, and timebase operations.
The following table summarizes the data acquisition modes that DriverLINX
supports for each subsystem with the Keithley KPCI-3140 Series.

DriverLINX Operations and Events
Applications construct DriverLINX data-acquisition tasks by combining a small
number of DriverLINX operations and events in many possible ways. The following
table summarizes the operations and events that DriverLINX supports for the
Keithley KPCI-3140 Series. Later sections for each DriverLINX subsystem will
describe the operations and events in more detail.
