Preface

x Preface KPCI-3110 and KPCI-3116 User’s Manual
This manual describes the features of the KPCI-3110 and KPCI-3116 boards, the capabilities of
the DriverLINX software, and how to configure the KPCI-3110 and KPCI-3116 board using
DriverLINX. Troubleshooting and calibration information is also provided.
Intended audience
This document is intended for engineers, scientists, technicians, or others responsible for using
and/or programming the KPCI-3110 and KPCI-3116 boards for data acquisition operations in
Microsoft Windows 95, Windows 98, or Windows NT. It is assumed that you have some famil-
iarity with data acquisition principles and that you understand your application.
NOTE Unless noted otherwise, this manual refers to both models collectively
as KPCI-3110.
This manual focuses primarily on describing the KPCI-3110 boards and their capabilities, set-
ting up the boards and their associated software, making typical hookups, and troubleshooting.
There are also sections that discuss calibration and summarize characteristics of DriverLINX
test-panel software.
What you should learn from this manual
This manual provides detailed information about the features of the KPCI-3110 and KPCI-3116
boards and the capabilities of the KPCI-3110 and KPCI-3116 Device Driver.
• Section 1 describes the major features of the board, as well as the supported software and
accessories for the board.
• Section 2 describes all of the board’s features and how to use them in your application.
• Section 3 describes how to install DriverLINX software, install the KPCI-3110 boards, wire
accessories, and configure the software to work with the boards.
• Section 4 describes the use of the DriverLINX Analog I/O Panel for testing board functions.
• Section 5 describes how to calibrate the analog I/O circuitry of the board.
• Section 6 provides information that you can use to resolve problems with the board, com-
puter, or DriverLINX should they occur.
• Appendix A lists the specifications of the board and data acquisition subsystems and the
associated features accessible using DriverLINX for the KPCI-3110 and KPCI-3116 boards.
• Appendix B shows the pin assignments for the connectors on the board and for the STP300
screw termination panel.
• Appendix C describes how to systematically isolate problems with the board, computer, soft-
ware, and programming.
• Appendix D provides information on special considerations when using your own screw ter-
minal panel.
• An index completes this manual.
