Chapter 1

Introducing the PCI-DAS6023 and PCI-DAS6025

Overview: PCI-DAS6023 and PCI-DAS6025 features

This manual explains how to install and use the PCI-DAS6023 and PCI-DAS6025 boards. These boards can be
used in a wide variety of measurement applications, including data logging, field testing and process control.

The PCI-DAS6025 provides 16 channels of 12-bit analog input, dual 12-bit analog outputs with a 10 kS/s per
channel update rate, 32 digital I/O lines and two 16-bit counter timers.

The PCI-DAS6023 provides 16 channels of 12-bit analog input, 8 digital I/O lines and two 16-bit counter
timers.

The analog inputs on each board can be configured as either eight differential or 16 single-ended channels. The
input ranges are bipolar, in four ranges of ±10 V, ±5 V, ±500 mV, and ±50 mV. The ranges are software­selectable.

Each board provides nine user-configurable trigger/clock/gate pins that are available at a 100-pin I/O connector.
Six of the pins are configurable as inputs and three pins are configurable as outputs.

Up to five PCI-DAS6000 series boards can be interconnected for I/O synchronization. Five trigger/strobes and a
synchronizing clock are available on a 14-pin header connector. Interrupts can be generated by up to seven
ADC sources and four DAC sources.

Both boards are equipped with an 82C54 counter chip that contains three 16-bit counters. Clock, gate, and
output signals from two of the counters are available on the board’s 100-pin I/O connector. The third counter is
used internally.

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

PCI-DAS6023 and PCI-DAS6025 boards are completely plug-and-play. There are no switches or jumpers to set
on these boards. 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 an available PCI slot.

2. Close your computer and turn it on.

If you are using an operating system with support for plug-and-play (such as Windows 2000 or Windows
XP), a dialog box pops up 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 will be prompted for the disk
containing this file. The MCC DAQ software contains this file. If required, insert the Measurement
Computing Data Acquisition Software 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 these boards. The high
speed components used on these boards generate 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-DAS6023 and PCI-DAS6025 User's Guide Installing the PCI-DAS6023 or PCI-DAS6025

Configuring the hardware

All of the hardware configuration options on the PCI-DAS6025/6023 are software controlled. You may 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 use these selections to
initialize the hardware according to these selections.

Following is an overview of the available hardware configuration options for the PCI-DAS6023 and PCI­DAS6025 boards. For general information regarding signal connection and configuration, refer to the Guide to
Signal Connections. This document is 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 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 second 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, 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 be measured 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. Each system can have one master and up to four slaves.

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.

By default, all DAQ-Sync connectors are configured as inputs (slave mode). In order to be useful, use software
to configure one board as the master and to define the signal sources of the slave boards. Refer to "DAQ-Sync

signals" on page 19 for more information.

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.
