Chapter 1

Introducing the PCI-DAS6071

Overview: PCI-DAS6071 features

This manual explains how to install and use the PCI-DAS6071 board.
The PCI-DAS6071 board provides either 32 differential or 64 single-ended analog inputs with 12-bit resolution.

Input ranges are software selectable as either bipolar or unipolar.

 Bipolar input ranges: ±10V, ±5V, ±2.5V, ±1V, ±0.5V, ±0.25V, ±0.1V and ±0.05V.
 Unipolar input ranges: 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 PCI-DAS6071 has eight lines of digital I/O, and provides two digital-to-analog outputs.
Each 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 3 ("Functional Details")
and Chapter 5("Specifications") for more information.

The PCI-DAS6071 provides triggering and synchronization capability. There are five trigger/strobes and a
synchronizing clock provided on a 14-pin header. The DAQ-Sync signals use dedicated pins. Only the direction
can be set. Refer to Chapter 2 ("Installing the Board") and Chapter 5 ("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 5 ("Specifications").

The PCI-DAS6071 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.

Unpacking the board

As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the PCI-DAS6071 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: [e-mail]

For international customers, contact your local distributor. Refer to the International Distributors section on our
web site at www.mccdaq.com/International.

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 www.mccdaq.com/PDFmanuals/DAQ-Software-

Quick-Start.pdf.

Installing the hardware

The PCI-DAS6071 board is completely plug-and-play. There are no switches or jumpers to set. 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. Turn your computer off, open it up, and insert your board into any available PCI slot.

2. Close your computer and turn it on.

If you are using an operating system with support for plug-and-play, a dialog box notifies you that new
hardware has been detected. If the information file for this board is not already loaded onto your PC, you
will be prompted for the disk containing this file. The MCC DAQ software contains this file. If required,
insert the MCC DAQ CD and click OK.

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.

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.

Configuring the hardware

All hardware configuration options on the PCI-DAS6071 are software controlled. You can select some of the
configuration options using InstaCal, such as the analog input configuration (64 single-ended or 32 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 www.mccdaq.com/signals/signals.pdf).

PCI-DAS6071 User's Guide Installing the PCI-DAS6071

Differential input mode

When all channels are configured for differential input mode, 32 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, 64 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.

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, 64 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

You can interconnect multiple boards in the PCI-DAS6000 series to synchronize data acquisition or data output.
To do this, order and install a CDS-14-x cable at the DAQ-Sync connectors (P2) between the boards to be
synchronized.

The "x" in the CDS-14-x part number specifies the number of connectors available on the cable, and therefore,
the number of boards you can interconnect. Using a CDS-14-2, you can connect two PCI-DAS6000 series
boards together for I/O synchronization. Using a CDS-14-3, you can synchronize three boards, and so on. You
can connect up to five PCI-DAS6000 series boards. A CDS-14-3 cable is shown in Figure 3 on page 14.

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.

D/A external reference

This product is equivalent in the specification and performance to the National Instruments™ (NI) PCI-6071E.
The Analog Output External Reference Bandwidth is specified at 1 MHz. This signal path is indeed 1 MHz;
however the performance of the D/A converter itself in multiplying mode varies with frequency and code. To
the best of our knowledge, this behavior is not fully explained in documentation presently available from NI.

If you are using the external reference feature of the analog outputs, please refer to the data sheet for the Analog
Devices AD7945. This document summarizes the performance of the D/A converter in multiplying mode.

Functional Details

Basic architecture

Figure 4 on page 17 shows a simplified block diagram of the PCI-DAS6071. This board provides all of the
functional elements shown in the figure.

The System Timing and Control (STC) is the logical center for all DAQ, DIO, and DAC (if applicable)
operations. It communicates over two major busses: a local bus and a memory bus.

The local bus carries digital I/O data and software commands from the PCI Bus Master. There are two Direct
Memory Access (DMA) channels provided for data transfers to the PC.

Primarily, the memory bus carries A/D and D/A related data and commands. There are three buffer memories
provided on the memory bus:

 The queue buffer (8K configuration memory) stores programmed channel numbers, gains, and offsets.
 The ADC buffer (8K FIFO [First In, First Out]) temporarily stores scanned and converted analog inputs.
 The DAC 16K buffer stores data to be output as analog waveforms.

Auxiliary input & output interface

The board's 100-pin I/O connector provides six software-selectable inputs, and three software-selectable
outputs. The signals are user-configurable clocks, triggers and gates.

Refer to "DAQ signal timing" on page 18 for information about these signals and their timing requirements.
The following table lists the available signals and the default signals that can be configured on the nine pins.
