Chapter 1

Introducing the PCI-DAS64/M2/16

Overview: PCI-DAS64/M2/16 features

The PCI-DAS64/M2/16 board offers a combination of high speed, channel count and resolution on a single
PCI-bus data acquisition board. It offers:

! 64 single-ended or 32 differential 16-bit analog inputs
! 2 MHz sample rate
! Two 16-bit analog outputs
! 100 kHz D/A update rate (16 K FIFO)
! 32 bits of digital I/O
! One 16-bit down-counter
! A variety of analog and digital trigger modes with software-selectable trigger levels and direction

The PCI-DAS64/M2/16 board is designed with Measurement Computing’s powerful System Timing Controller
(STC) chip. The STC chip controls all A/D sampling and D/A update rates as well as controlling the 8K A/D
FIFO, the 8K gain/channel queue and the 16K D/A FIFO buffer. This functionality is based on the STC chip’s
use of an on-board 32K x 16 SRAM. The STC chip assigns functions to various parts of the SRAM, such as the
A/D FIFO buffer, and provides full-speed control and arbitration among the various functions using the various
sections of the SRAM buffer.

The STC allows simultaneous full speed A/D sampling, D/A updating and gain/channel queue sequencing, with
variable inter-sample timing if desired. The STC chip performs these functions up to 5 MHz, and is available as
an OEM component for use in your own designs. The board provides bus-mastering and scatter-gather
functionality to assure the desired system timing is maintained.

The PCI-DAS64/M2/16 is completely plug-and-play, with no switches, jumpers or potentiometers on the board.
All board addresses, interrupt channels, etc., are set by your computers plug-and-play software. Calibration is
performed via software by using on-board trim D/A converters.

Software features

For information on the features of InstaCal and the other software included with your PCI-DAS64/M2/16, 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 products for use with the PCI-DAS64/M2/16. Refer to the "Field wiring,

signal termination and conditioning" section on page 2-7 for a complete list of compatible accessory

products.

Unpacking the PCI-DAS64/M2/16

As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the PCI-DAS64/M2/16 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-DAS64/M2/16

The PCI-DAS64/M2/16 board is completely plug-and-play, with 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.

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.

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

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 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
60 minutes before acquiring data. This warm-up period is required 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.

OK.

PCI-DAS64/M2/16 User's Guide Installing the PCI-DAS64/M2/16

Calibrate the PCI-DAS64/M2/16 after it has warmed up and immediately before making critical
measurements

Use the InstaCal utility to calibrate the PCI-DAS64/M2/16 after it has fully warmed up. For best results,
calibrate the board immediately before making critical measurements. The high resolution analog components
on the board are somewhat sensitive to temperature. This pre-measurement calibration insures that your board is
operating at the optimum calibration values.

Configuring the PCI-DAS64/M2/16

All hardware configuration options on the PCI-DAS64/M2/16 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), and the edge used for triggering when using an external pacer.

Once configured, any program that uses Measurement Computing’s Universal Library will initialize the
hardware according to these selections.
