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 ±1.25 V
Unipolar: 0 to 10 V, 0 to 5 V, 0 to 2.5 V and 0 to 1.25 V
The PCI-DAS1002 provides a 200 kHz sample rate.
The PCI-DAS1002 also provides two channels of 12-bit analog output. Analog output ranges are ±10 V and ±5
V (bipolar) and 0-10 V, 0-5 V (unipolar).
The PCI-DAS1002 offers 24-bits of parallel, digital I/O (two 8-bit ports and two 4-bit ports). You can configure
each port independently as input or output.
This board has an 82C54 counter chip which has three user-accessible 16-bit counters. Clock, gate, and output
signals from two of three counters are available on a 100-pin connector. The third counter is used internally.
The PCI-DAS1002 is fully plug-and-play. All addresses and interrupt channels are set with software.
Software features
For information on the features of InstaCal and the other software included with your PCI-DAS1002, refer to
the Quick Start Guide that shipped with your device. The Quick Start Guide is also available in PDF at

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. Before removing the PCI-DAS1002 from its packaging, ground yourself using a wrist strap or by
simply touching the computer chassis or other grounded object to eliminate any stored static charge.
If any components are missing or damaged, notify Measurement Computing Corporation immediately by
phone, fax, or e-mail:
Phone: [phone] and follow the instructions for reaching Tech Support.
Fax: [phone] to the attention of Tech Support
Email: [email protected]
Installing the software
Refer to the Quick Start Guide for instructions on installing the software on the Measurement Computing Data
Acquisition Software CD. This booklet is available in PDF at
Quick-Start.pdf.
www.mccdaq.com/PDFmanuals/DAQ-Software-
Installing the hardware
The PCI-DAS1002 board is completely plug-and-play. There are no switches or jumpers to set on the board.
Configuration is controlled by your system's BIOS. To install your board, follow the steps below.
Install the MCC DAQ software before you install your board
The driver needed to run your board is installed with the MCC DAQ software. Therefore, you need to install the
MCC DAQ software before you install your board. Refer to the Quick Start Guide for instructions on installing
the software.
1.
2.
3. To test your installation and configure your board, run the InstaCal utility installed in the previous section.
Refer to the Quick Start Guide that came with your board for information on how to initially set up and
load InstaCal.
If you are using an operating system with support for plug-and-play (such as Windows 2000 or
Windows XP), a dialog box opens as the system loads, indicating that new hardware has been detected. The
information file for this board should have already been loaded onto your PC when you installed the
Measurement Computing Data Acquisition Software CD supplied with your board, and should be detected
automatically by Windows. If you have not installed this software, cancel the dialog and install it now.
Close your computer and turn it on.
Turn your computer off, open it up, and insert your board into an available PCI slot.
Allow your computer to warm up for at least 15 minutes before acquiring data with this board. The high speed
components used on the board generates heat, and it takes this amount of time for a board to reach steady state
if it has been powered off for a significant amount of time.

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.
For general information regarding analog signal connection and configuration, refer to the Guide to Signal
Connections (available on our web site at www.mccdaq.com/signals/signals.pdf).
Differential input mode
When all channels are configured for differential input mode, eight analog input channels are available. In this
mode, the input signal is measured with respect to the low input. The input signal is delivered through three
wires:
The wire carrying the signal to be measured connects to CH# IN HI.
The wire carrying the reference signal connects to CH# IN LO.
The third wire, typically a system ground, connects to LLGND.
Single-ended input mode
When all channels are configured for single-ended input mode, 16 analog input channels are available. In this
mode, the input signal is referenced to the board's signal ground (LLGND). The input signal is delivered
through two wires:
The wire carrying the signal to be measured connects to CH# IN HI.
The second wire connects to LLGND.

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.
Programming languages
Measurement Computing’s Universal Library®provides access to board functions from a variety of Windows
programming languages. If you are planning to write programs, or would like to run the example programs,
refer to the Universal Library User's Guide (available on our web site at www.mccdaq.com/PDFmanuals/sm-
ul-user-guide.pdf).
Packaged applications programs
Many packaged application programs now have drivers for your board. If the package you own does not have
drivers for the board, please fax or e-mail the package name and the revision number from the install disks. We
will research the package for you and advise how to obtain drivers.
Some application drivers are included with the Universal Library package, but not with the application package.
If you have purchased an application package directly from the software vendor, you may need to purchase our
Universal Library and drivers. Please contact us by phone, fax, or e-mail:
Phone: [phone] and follow the instructions for reaching Tech Support.
Fax: [phone] to the attention of Tech Support
Email: [email protected]
Register-level programming
You should use the Universal Library or one of the packaged application programs mentioned above to control
your board. Only experienced programmers should perform register-level programming.
If you need to program at the register level in your application, refer to the Register Map for the PCI-DAS1000
Series (available at www.mccdaq.com/registermaps/RegMapSTC1000.pdf).

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.
Calibration theory
The PCI-DAS1002 is shipped fully calibrated from the factory with calibration coefficients stored in nvRAM.
When using Universal Library at run time, these calibration factors are loaded into system memory and are
automatically retrieved each time a different DAC/ADC range is specified.
The analog input circuits are calibrated for both offset and gain ( ).Figure 3
Figure 3. Analog input circuit calibration
Offset calibration for the analog input is performed directly on the input amplifier (PGIA) with coarse and
fine trim DACs acting on the amplifier.
For input gain calibration, a precision calibration reference is used with coarse and fine trim DACs acting
on the ADC.

Offset adjustments are made in the output buffer section. The tuning range of this adjustment allows for
max DAC and output buffer offsets.
Gain calibration is performed via DAC reference adjustments.

Accuracy
Accuracies are listed for a 200 kHz sampling rate, 100 sample average, single channel operation, a 15 minute
warm-up, and operational temperatures within ±2 °C of internal calibration temperature. The calibrator test
source high side is tied to Channel 0 In and the low side is tied to AGND.

0 to 2.500 V ±2.5 LSB max
0 to 1.250 V ±2.5 LSB max
Each PCI-DAS1002 is tested at the factory to assure the board’s overall error does not exceed accuracy limits
described in Table 2 above.
Table 3. Calibrated accuracy components (in LSB)
Range Gain Error Offset Error DLE ILE
All ranges ±1.0 max ±1.0 max ±0.75 max ±0.5 max
As shown in Table 3, total board error is a combination of gain, offset, differential linearity and integral
linearity error. The theoretical worst-case error of the board may be calculated by summing these component
errors. Worst case errors are realized only in the unlikely event that each of the component errors are at their
maximum level, and causing error in the same direction.
Crosstalk
Crosstalk is defined here as the influence of one channel upon another when scanning two channels at the
maximum rate. A full scale 100 Hz triangle wave is input on channel 1; Channel 0 is tied to analog ground at
the 100-pin user connector. The table below summarizes the influence of channel 1 on channel 0 with the
effects of noise removed. The residue on channel zero is described in LSB’s.

Condition Crosstalk Per channel Rate ADC Rate
All ranges 2 LSB pk-pk 100 kHz 200 kHz
Noise performance
Table 5 below summarizes the noise performance for the PCI-DAS1002. Noise distribution is determined by
gathering 50 K samples at 200 kHz with inputs tied to ground at the user connector.

Each PCI-DAS1002 is tested at the factory to assure absolute accuracy.
Total analog output error is a combination of gain, offset, integral linearity and differential linearity error. The
theoretical worst-case error of the board may be calculated by summing these component errors. Worst case
error is realized only in the unlikely event that each of the component errors are at their maximum level, and
causing error in the same direction. Although an examination of the chart and a summation of the maximum
theoretical errors shows that the board could theoretically exhibit a ±3.5 LSB error, our testing assures this error
is never realized in a board that we ship.
