Preface About this User's Guide What you will learn from this user's guide This user's guide explains how to install, configure, and use the PCI-DAS1002 so that you get the most out of its analog, digital, and timing I/O features. This user's guide also refers you to related documents available on our web site, and to technical support resources.
Chapter 1 Introducing the PCI-DAS1002 Overview: PCI-DAS1002 features This manual explains how to install and use the PCI-DAS1002. This board is a multifunction analog and digital I/O board designed for the PCI bus. The PCI-DAS1002 provides either 16 single-ended or eight differential analog inputs. Input ranges are software-selectable as either bipolar or unipolar. Analog input ranges for the PCI-DAS1002 are software programmable for the following ranges: Bipolar: ±10 V, ±5 V, ±2.5 V, and ±1.

Chapter 2 Installing the PCI-DAS1002 What is included with your PCI-DAS1002 As you unpack your board, make sure each of the items shown below is included: Hardware PCI-DAS1002 Additional documentation In addition to this hardware user's guide, you should also receive the Quick Start Guide (available in PDF at www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf).
PCI-DAS1002 User's Manual Installing the PCI-DAS1002 Signal termination and conditioning accessories MCC provides signal termination and conditioning products for use with the PCI-DAS1002. Refer to the "Field wiring and signal termination" section for a complete list of compatible accessory products. Unpacking the PCI-DAS1002 As with any electronic device, you should take care while handling to avoid damage from static electricity.
PCI-DAS1002 User's Manual Installing the PCI-DAS1002 Configuring the hardware All hardware configuration options on the PCI-DAS1002 are software controlled. You can select some of the configuration options using InstaCal, such as the analog input configuration (16 single-ended or eight differential channels), and the source for the two independent counters. Once selected, any program that uses the Universal Library will initialize the hardware according to these selections.

Chapter 3 Programming and Developing Applications After following the installation instructions in Chapter 2, your board should now be installed and ready for use. Although the board is part of the larger DAS family, in general there may be no correspondence among registers for different boards. Software written at the register level for other DAS models will not function correctly with your board.
Chapter 4 Calibrating the Board Introduction Calibrate the board using the InstaCal utility after the board has fully warmed up. The recommended warm-up time is 15 minutes. For best results, calibrate the board immediately before making critical measurements. The high resolution analog components on the board are sensitive to temperature. Pre-measurement calibration ensures that your board is operating at optimum calibration values.
