Chapter 1
Introducing the PCI-DAS6052 Series Board
Overview: PCI-DAS6052 features
This manual explains how to install and use the PCI-DAS6052 board.
The PCI-DAS6052 board has eight lines of digital I/O, and two digital-to-analog
outputs. It provides either eight differential or 16 single-ended analog inputs with 16 bit
resolution. Input ranges are either Bipolar or Unipolar. Bipolar input ranges are ±10V,
±5V, ±2.5V, ±1V, ±0.5V, ±0.25V, ±0.1V and ±0.05V. Unipolar input ranges are 0 to
10V, 0 to 5V, 0 to 2V, 0 to 1V, 0 to 0.5V, 0 to 0.2V and 0 to 0.1V. The input ranges are
software-selectable.
The board has nine user-configurable trigger/clock/gate pins that are available at a
100-pin I/O connector. Six pins are configurable as inputs and three are configurable as
outputs. Refer to Chapter 4 ("Functional Details") and Chapter 6 ("Specifications") for
more information.
The PCI-DAS6052 provides triggering and synchronization capability. There are five
trigger/strobes and a synchronizing clock provided on a 14-pin header. Refer to Chapter
2 ("Installing the Board") and Chapter 6 ("Specifications") for more information on
these signals.
Interrupts can be generated by up to seven ADC sources and four DAC sources.
Interrupt sources are listed in Chapter 6 ("Specifications").
The PCI-DAS6052 board contains an 82C54 counter chip, which consists of three 16-bit
counters. Clock, gate, and output signals from two of the three counters are available on
the 100-pin I/O connector. The third counter is used internally.

Software features–InstaCaland Universal Library
The PCI-DAS6052 ships with the InstaCalsoftware utility package. InstaCal is a
complete installation, calibration and test program for data acquisition and control
boards. Complete with extensive error checking, InstaCal guides you through
installation and setup of your data acquisition board and creates the board configuration
file for use by your program or application software package. The procedure for
installing InstaCal is explained in the Software Installation Manual (available on our
web site at http://www.mccdaq.com/PDFmanuals/sm-installation.pdf).
The optional Universal Libraryfully supports the PCI-DAS6052 board. The Universal
Library is a complete set of I/O libraries and drivers for all MCC boards, and for all
Windows-based languages. When using the Universal Library, you can switch boards or
even programming languages and the syntax remains constant.

Unpacking the board
The PCI-DAS6052 boards are shipped in an antistatic container to prevent damage by an
electrostatic discharge. To avoid such damage, perform the following procedure when
unpacking and handling your board.
1.
2.
3.
Before opening the antistatic container, ground yourself with a wrist-grounding
strap or by holding onto a grounded object (such as the computer chassis).
Touch the antistatic container to the computer chassis before removing the board
from the container.
Remove the board from the container. Never touch the exposed pins or circuit
connections on the board.
Installing the software
Install the InstaCal software included with your board before you install the hardware. If
you ordered the Universal Library software, install that software instead. InstaCal is
installed at the same time as the Universal Library.
Installing the software first ensures that the information required for proper board
detection is installed and available at boot up. The procedure for installing InstaCal is
explained in the Software Installation Manual included with your board (and also
available on our web site at www.mccdaq.com/PDFmanuals/sm-installation.pdf).
If you ordered the Universal Library…
If you ordered the optional Universal Library, use that CD to install both InstaCal and
the Universal Library.

PCI-DAS6052 User's Guide Installing the Board
Installing the hardware
The PCI-DAS6052 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 InstaCal before you install your board
The driver needed to run your board is installed with InstaCal. Therefore, you need to
install InstaCal before you install your board. Follow the directions for installing
InstaCal in the Software Installation Manual shipped with your board.
1.
2.
3.
Turn your computer off, open it up, and insert your board into an available PCI slot.
Close your computer and turn it on.
If you are using an operating system with support for plug-and-play (such as
Windows 95 or Windows 2000), a dialog box displays as the system loads,
indicating that new hardware has been detected.
If the information file for this board is not already loaded onto your PC, you are
prompted for the disk containing this file. The InstaCal software supplied with your
board contains this file. If required, insert the disk or CD and click OK.
To test your installation and configure your board, run the InstaCal utility you
installed in the previous section. Refer to the Software Installation Manual that
came with your board (www.mccdaq.com/PDFmanuals/sm-installation.pdf) for
information on how to initially set up and load InstaCal.
4. If your board has been powered-off for more than 10 minutes, in order for it to
achieve its rated accuracy, 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-DAS6052 User's Guide Installing the Board
Configuring the hardware
All hardware configuration options on the PCI-DAS6052 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), the edge used for
triggering when using an external pacer, 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.
Following is an overview of the available hardware configuration options for this board.
There is additional general information regarding analog signal connection and
configuration in the Guide to Signal Connections (available on our web site at
http://www.measurementcomputing.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 is connected to LLGND.
Differential input mode is the preferred configuration for applications in noisy
environments, or when the signal source is referenced to a potential other than PC
ground.
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 other wire is connected to LLGND.
2-5

PCI-DAS6052 User's Guide Installing the Board
Non-referenced single-ended input mode
This mode is a compromise between differential and single-ended modes. It offers some
of the advantages of each mode. Using non-referenced single-ended mode, you can still
get noise rejection, but not the limitation in the number of channels resulting from a
fully differential configuration. The possible downside is that the external reference
input must be the same for every channel. It is equivalent to configuring the inputs for
differential mode and then tying all of the low inputs together and using that node as the
reference input.
When configured for non-referenced single-ended input mode, 16 analog input channels
are available. In this mode, each input signal is not referenced to the board’s ground, but
to a common reference signal (AISENSE). The input signal is delivered through three
wires:
The wire carrying the signal to measure connects to CH# IN HI.
The wire carrying the reference signal connects to AISENSE.
The third wire is connected to LLGND.
This mode is useful when the application calls for differential input mode but the
limitation on channel count prevents it.
DAQ-Sync configuration
Multiple boards in the PCI-DAS6000 series may be interconnected to synchronize data
acquisition or data output. To do this, order and install a CDS-14-xcable at the
DAQ-Sync connectors (P2) between the boards to be synchronized.
The “x” in the CDS-14-x part number identifies the number of connectors available on
the cable and therefore, the number of boards that may be interconnected. Using a
CDS-14-2, two PCI-DAS6000 series boards may be connected together for I/O
synchronization. Using a CDS-14-3, three boards may be synchronized and so on up to
five PCI-DAS6000 series boards. A CDS-14-3 cable is shown in Fi on
page 2-11.
gure 2-3
By default, all DAQ-Sync connectors are configured as inputs (slave mode). In order to
be useful, one board must be set through software to serve as the master and the signal
sources of the slave boards must be defined. Detailed information regarding software
configuration of these functions is available in the STC Register Map for the PCI-DAS
6000 Series. This document is available from our web site at
www.mccdaq.com/registermaps/RegMapSTC6000.pdf.
