Chapter 1: Introduction
About the PowerDAQ board
This chapter describes the basic features of the PowerDAQ boards.
Overview
Thank you for purchasing a PowerDAQ board. The PowerDAQ board
was designed from the ground-up to overcome the problems associated
with previous ISA-based data acquisition boards.
The associated PowerDAQ software has been written specifically for
these products, using advanced software design.
Features
The major features of the PowerDAQ board are:
• 24-bit 80/100 MHz Motorola 56301 DSP (Digital Signal
Processor)
• PCI Bus Host PC Interface (PCI 2.1 Compliant)
• Custom designed programmable gain amplifier
• Analog Input - 16/64 channels- 12, 14 or 16 bit AD
resolutions
• Analog Output - 2 channels - 2K DSP based FIFO
• Digital In – 16 inputs (24 on PDL-MF)
• Digital Out – 16 outputs (24 on PDL-MF)
• Three Counter/Timers (8254) – 3 Clock In/Gate control
• Auto calibration (3 24-bit DSP shared counters on PDL-
MF)
• Extensive triggering and clocking of Analog Input
• Extensive triggering and clocking of Analog Output
• Simultaneous Analog In, Analog Out, Digital In, Digital
Out and Counter/Timer operations

Note The PDXI-MFS series have onboard sample and hold
amplifiers for each channel. These are part of the boards
hardware design and do not require any software programming
to be enabled.

Installation and
Configuration

Chapter 2: Installation and Configuration
Before You Begin
Before you install your PowerDAQ board, you should read and
understand the following information.
System Requirements:
To install and run your PowerDAQ board, you must have the following:
• A PC with PCI slots, a Pentium-class processor, and a
BIOS that is compliant with
Revision 2.1
• Windows 95, 98, NT 4.0, 2000/XP
• Linux, QNX, RTLinux
or greater
Packing List
In your PowerDAQ package you should have received:
• A PowerDAQ board
• A user manual
• A CD containing the PowerDAQ software development kit
(SDK) and documentation
PCI Local Bus Specification
Note The CD label shows the version number of the SDK.
• A calibration certificate
Precautions
PowerDAQ boards contain sensitive electronic components. When
handling your PowerDAQ board, you should:
• Ensure that you are properly grounded.
• While holding the board in its antistatic bag, discharge
any static electricity by touching the metal part of your
PC.

Chapter 2: Installation and Configuration
Installing PowerDAQ
Installing the Board:
To install your PowerDAQ board:
1. Turn off your PC and remove the cover from your PC.
2. Locate an empty PCI slot and remove the slot cover on
the back panel of your PC. Save the screw.
3. Insert the board into the PCI slot.
4. Fasten the board’s mounting bracket to your PC’s back
panel with the screw that held the slot cover.
5. Inspect the board and ensure that it has been properly
inserted in the slot.
6. Replace the cover of your PC and turn on the power.
Note The PowerDAQ PCI interface must be set to 32-bit, 5V
power and signaling (the default setting for most PCs).

Installing the Software
To install the PowerDAQ SDK:
1. Start your PC and, if you are running Windows NT, login as an
administrator.
2. Insert the PowerDAQ CD into your CD-ROM drive. Windows should
automatically start the PowerDAQ Setup program. If you see the
OMEGA logo and then the PowerDAQ welcome screen, go to step
6.
3. If the Setup program does not start automatically, select Run from
the Start menu.
4. Enter D:\Setup.exe in the Open: textbox. (Substitute the correct
letter if D is not the drive letter of your CD-ROM drive.)
5. Click OK.
6. As the Setup program runs, you will be asked to enter information
about your PowerDAQ configuration. Unless you are an expert user
and have specific requirements, you should select a Typical
installation and accept the default configuration.

7. If the Setup program asks for information about third-party
software packages that you do not have installed on your PC, leave
the textbox blank and click the Next button.
8. When the installation is complete, you should restart your PC when
prompted.
Confirming the Installation
Once you have installed the PowerDAQ board and software on your PC,
you should confirm the installation:
• Select Programs ! PowerDAQ !
the Start menu. If the Control Panel applet is displayed
and correctly identifies your PowerDAQ board, the
installation is correct.

Input Modes:
The analog input section multiplexes the active input channels (64/16
single-ended or 32/8)differential) to a single 12- or 16-bit successive
approximation analog-to-digital converter (ADC).
Single-Ended:
PowerDAQ boards can be configured to operate with either a singleended or differential input. Single-ended inputs allow up to 64 channels
and share a common return path connected to analog ground (AGND).

Figure 5: Single-ended Inputs and pseudo-differential
inputs
Note Unused channels should be shorted to ground using 0-
to 1-KΩ resistor. In pseudo-differential mode ground reference
level is taken from remote system.
Differential Inputs:
Differential inputs allow up to 32 channels. Each differential channel
uses two analog channels — one analog channel connects to the positive
input of the programmable gain amplifier, and the other to the
negative.
