Configuring the KPCMCIA-PIO24
Introduction
This manual explains the steps and special features that apply to Keithley’s
KPCMCIA-PIO24 card.
Installing and configuring DriverLINX for the Keithley KPCMCIA-PIO24 card
requires three steps:
1. To install your KPCMCIA-PIO24 hardware, read and follow the
instructions in the hardware manual.
2. To install DriverLINX, follow the general procedure outlined in the
"Read Me First" material on the installation CD.
3. To configure DriverLINX, use the DriverLINX Configuration Panel.
Also see “Configure DriverLINX Device Dialog” on page 9 for
configuration options specific to a Keithley KPCMCIA-PIO24 model.
Configure DriverLINX Device Dialog
DriverLINX uses a standardized configuration protocol for all data-acquisition
hardware. Even though Windows 95/98/Me automatically selects the hardware base
address and interrupt channel for the KPCMCIA-PIO24, you must still follow the
configuration process to assign a DriverLINX Logical Device number to a specific
KPCMCIA-PIO24 model in your computer.
When you activate the S
DriverLINX displays the Configure DriverLINX Device dialog. The following
sections describe your choices for configuring DriverLINX to work with a Keithley
KPCMCIA-PIO24 model.

Device Subsystem Page
Note: The Configure DriverLINX Device dialog appears differently under different versions of
Windows.
Use the Device subsystem page to tell DriverLINX the model name and address of
your KPCMCIA-PIO24 card.
Vendor
The Vendor property displays “Keithley Instruments, Inc.” It is a read-only property.
Device
Windows 95/98/Me/2000
Windows NT
The Device property designates the Logical Device you are configuring. It is a readonly property. To change it, first save (OK) or quit (Cancel) the current
configuration. Then select or create a new Logical Device using the DriverLINX
Configuration Panel.
Model
The Model property selects the hardware model of the card you’re configuring.
This driver supports only model KPCMCIA-PIO24.
Address
Windows 95/98/Me/2000 automatically selects an appropriate address and ignores
this property.
The A
ddress property selects the I/O port address for the card. The default address
used by DriverLINX is 768 decimal or 0x300 hex. If you have another peripheral
card at the same address, you will have to select a free range of 8 addresses.
Detect
The Detect property enables and disables DriverLINX’s hardware detection and
testing algorithms. For maximum system reliability, always leave this check box
marked.

Calibrate
The Calibrate property enables and disables hardware auto-calibration. For best
accuracy, always leave this check box marked.

The Special… button displays a dialog for configuring any special, hardware-specific
settings. For the KPCMCIA-PIO24 , Logical Device c onfiguration doe s not require
any special settings so DriverLINX disables the S

Channels
The Channels property allows you to select a Logical Channel for configuration or
viewing the channel’s range. Only the KPCMCIA-PIO24 digital input/output
channels support programmable configuration.
DriverLINX defines the following Logical Channels for the KPCMCIA-PIO24
digital inputs:

3 External Clock INTERRUPT INPUT
Range
The Range property specifies the supported digital input range for the selected
Logical Channel. This is a read-only property.
Interrupt
For Windows 95/98/Me/2000, the operating system automatically determines the
interrupt channel for the KPCMCIA-PIO24 card. DriverLINX disables this property.
For Windows NT, select a free interrupt request level to support interrupt mode
transfers. Valid IRQ levels are: 1 - 15.
DMA level
The KPCMCIA-PIO24 does not use system DMA channels. DriverLINX disables
this property and displays it as blank.

for either input or output.
DriverLINX supports two methods for configuring a digital I/O port. The simplified
method configures the whole port, while the advanced method allows you to
configure groups of digital I/O lines. Select the channel to configure in the dropdown channel list and enter a S

2. Check the Initialize box.
3. Enter one of the following values for the S
the entire port:
• 1—configures all lines in the port as input, or
• 0—configures all lines in the port as output.
Advanced Digital I/O Port Configuration
With advanced configuration, you can divide the port into groups of 1, 2, 4 or 8 lines
and configure each group separately.
For advanced configuration:
1. Select the channel number of the port to configure in the drop-down
channel list.
2. Check the Initialize box.
3. Enter a value for the S
etup property as described below.

indicates the input/output direction of the lines in the group. The leastsignificant bit configures the first group. High-order bits to the left
configure subsequent groups.
For each bit, enter one of the following values to configure the group:
• 1—configures all lines in the group as input, or
• 0—configures all lines in the group as output.
• Group Size Field—consists of a binary 1 immediately to the left of

Channels
The Channels property allows you to select a Logical Channel for initialization or
viewing the channel’s range. KPCMCIA-PIO24 card has three digital input/output

Introduction
This chapter shows you how to set up and use KPCMCIA-PIO24 hardware features
with DriverLINX. The descriptions here use the Edit Service Request dialogs for
language and API i ndependence. For the corre ct syntax with the language you’re
using, please see the DriverLINX Technical Reference Manuals. For DriverLINX
examples in your programming language, please see the source code examples in the
subdirectories of your DriverLINX installation directory or on the original
Distribution Media.
DriverLINX Hardware Model for KPCMCIA-PIO24
By design, DriverLINX provides a portable, hardware-independent API for dataacquisition boards while still allowing applications to access unique or proprietary
hardware features of specific products. To achieve this goal, DriverLINX maps a
hardware-independent, or abstract, data-acquisition model onto KPCMCIA-PIO24
hardware capabilities.
The following sections describe how DriverLINX implements KPCMCIA-PIO24
hardware features as Subsystems, Modes, Operations, Events, Logical Channels,
Buffers, and Messages.
DriverLINX Subsystems
The KPCMCIA-PIO24 supports four of DriverLINX’s six Logical Subsystems:
1. Device—refers to the KPCMCIA-PIO24 card as a whole.
2. Analog Input—refers to the analog input channels, clocks, and control
signals. The KPCMCIA-PIO24 does not support analog input.
3. Analog Output—refers to the analog output channels, clocks, and
control signals. The KPCMCIA-PIO24 does not support analog output.
4. Digital Input—refers to the 8-bit digital input/output ports as well as
the 1-bit digital input (TTL) control signals, INTERRUPT INPUT.
