Chapter 1

Introducing the PCI-DAS6402/16

Overview: PCI-DAS6402/16 features

This manual explains how to install and use the PCI-DAS6402/16.

The PCI-DAS6402/16 is a multifunction measurement and control board designed to operate in computers with
PCI bus accessory slots. The architecture of the board is loosely based on the original CIO-DAS16, the standard
of ISA bus data acquisition.

The PCI-DAS6402/16 provides the following features:

! 32 differential or 64 single-ended 16-bit analog inputs
! 100-pin high density I/O connector and a 40-pin auxiliary connector
! 200 kHz sample rate
! Two 16-bit analog outputs with update rates of up to 100 kHz
! One 16-bit counter
! 24 DIO bits on the auxiliary connector; four DI bits and 4 DO bits on the 100-pin connector
! Provides arbitrary waveform generation

Analog input ranges are selectable via software as bipolar or unipolar. Bipolar input ranges are ±10 V, ±5 V,
±2.5 V and ±1.25 V. Unipolar input ranges are 0 to 10 V, 0 to 5 V, 0 to 2.5 V and 0 to 1.25 V. The PCI­DAS6402/16 has an analog trigger input. The trigger level and direction are software configurable.

The PCI-DAS6402/16 board is completely plug and play, with no switches, jumpers or potentiometers to set.
All board addresses and interrupt sources are set with software.

Software features

For information on the features of InstaCal and the other software included with your PCI-DAS6402/16, refer
to the Quick Start Guide that shipped with your device. The Quick Start Guide is also available in PDF at

PCI-DAS6402/16 User's Guide Installing the PCI-DAS6402/16

Unpacking the PCI-DAS6402/16

As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the PCI-DAS6402/16 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]

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 PCI-DAS6402/16

The PCI-DAS6402/16 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.

Turn your computer off, open it up, and insert your board into an available PCI slot.

1.

Close your computer and turn it on.

2.

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 you installed in the previous
section. Refer to the Quick Start Guide that came with your board www.mccdaq.com/PDFmanuals/sm-

installation.pdf for information on how to initially set up and load InstaCal.

If your board has been powered-off for more than 10 minutes, allow your computer to warm up for at least
15 minutes before acquiring data. This warm-up period is required in order for the board to achieve its rated
accuracy. The high speed components used on the board 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.

Configuring the PCI-DAS6402/16

All of the hardware configuration options on the PCI-DAS6402/16 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.

PCI-DAS6402/16 User's Guide Installing the PCI-DAS6402/16

Information on signal connections

General information regarding signal connection and configuration is available in 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, 32 analog input channels are available. In this
mode, the input signal is measured with respect to the low input. The input signal is typically delivered through
three wires:

! The wire carrying the signal to be measured connects to CH# HI.
! The wire carrying the reference signal connects to CH# LO.
! The third wire, typically a system ground, 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 second wire is connected to LLGND.

Connecting the board for I/O operations

The PCI-DAS6402/16 uses a 100-pin I/O connector (refer to on page 2-4 and T on page 2-5).
The 100-pin connector provides a much greater signal density than the traditional 37-pin connector. Make
accurate notes and pay careful attention to wire connections. In a large system, a misplaced wire can create
hours of unnecessary troubleshooting.
