PowerDAQ™ PD2-AO boards.
About the PowerDAQ™ Analog Output
series board
Thank you for purchasing a PowerDAQ™ Analog Output
series board. The board you received is either a PD2-AO PCIbus board or a PDXI-AO CompactPCI bus board. These
boards differ in certain hardware respects however the
software is the same.
The PDXI series Analog Output boards utilize all advantages
of the PXI/cPCI form-factor.
The associated PowerDAQ™ Software Suite (PD-SDK) has
been written specifically for these products.
Overview
The PowerDAQ analog output boards are configured as 8,
16, 32 or 96 channels. The PDXI versions are available in 8,
16 and 32 channel versions. The PowerDAQ Analog Output
board uses 16-bit DACs and allows you to configure the
start up states for each channel (200ms maximum delay
between system reset and power-on value loading). The onboard DSP/PCI interface allows you to use up to three 24bit counter timers, high-speed IRQ/External Clock lines,
eight digital inputs and eight high-drive (-32/64ma) digital
outputs. Additionally each board has a special calibration
subsystem, which is used to calibrate each analog output
channel.

Screw the bracket and replace the cover.
Turn the PC on.
PDXI board installation:
1. Turn off your PC.
2. Remove the slot cover.
3. Insert the PowerDAQ PDXI-AO board into a slot.
4. Screw the bracket.
5. Turn the PC on.
The PowerDAQ AO board is now installed. All board
configurations are controlled via software using the PDSUITE.
Note For the Windows 95/98/Me/2000/XP platforms, you
should install PowerDAQ Software Suite prior the board
installation.
Installing Multiple Boards
You can install multiple PowerDAQ AO boards in one PC.
You are limited to the number of PCI/PDXI slots in your PC.
Software
PowerDAQ Software Suite CD contains drivers and software
(example code with source code) for Windows, Linux and
QNX (optional). You can always download the latest
software suite from www.PowerDAQ.com/download.
Installation
From the CD, run the SETUP.exe program. The setup
program will take you through the installation process. If
you downloaded the PowerDAQ software from the web you
just need to run the file downloaded and follow the setup
instructions.
9
Page 18
Chapter 2: Installation and Configuration
As the installation process modifies your Windows registry,
you must only install or uninstall the software using the
appropriate programs.
Note Never delete the PowerDAQ software from you PC
directly. Always use Uninstall program from PowerDAQ folder
or Control Panel/Add-Remove Programs applet.
Note Once the installation is complete, the PC must be
rebooted for proper operation.
Note Windows NT/2000/XP users must be logged in as an
administrator or have equivalent access.
Base address, DMA, Interrupt settings
The PowerDAQ AO boards are configured automatically by
the computer BIOS on power up. Usually you do not have to
set any base address, DMA channels or interrupt levels. The
PowerDAQ driver is designed to share interrupts over PCI
devices but very rarely will the BIOS assign same interrupt to
mass-storage devices such as a SCSI controller or video card
and a PowerDAQ board. In this case it could be significant
latency between the time when board fires an interrupt and
the time the PowerDAQ driver actually receives it. In this
case we recommend changing your BIOS settings and
assigning a dedicated interrupt for the PowerDAQ board.
Please refer to your motherboard/computer manual for the
BIOS settings change procedure.
Diagnostics
In order to confirm board operation, install the PowerDAQ
Suite. This automatically installs the PowerDAQ application
control panel diagnostic program that will display all
available PowerDAQ boards in your system.

Screw Terminal Panels
The PD2-AO-STP-16/32 is a 16/32-channel screw terminal
panel, which also includes connections for the counter
timers, high speed interrupt/synchronization lines and DIO
ports. Using the jumpers, each sense line can be connected
to the appropriate output directly on the screw terminal.
Note For the all PDXI-AO boards, the sense to force line
jumpers are located directly on the board. All jumpers should
be removed from the PD2-AO-STP panel in this case.
Because of compatible pin-outs, the PD-BNC-xx terminals
can be used with PD2-AO-8[16][32] boards. Custom terminal
panels are available. Please contact the factory for more
details.

The PowerDAQ II analog output boards are configured as 8,
16, 32 or 96 sixteen-bit output channels. On the PD2-AO8[16][32] each channel has an optional sense line to provide
16-bit accuracy at rated output current. The PDXI-AO board
allows the use of sense lines on the first sixteen channels by
installing on-board jumpers. The PD2-AO-96 does not
provide the sense line option.
Note The default sense line option is not available on PD2AO boards because of noise considerations – high currents
going through the cable induce more noise) and sense lines
carry the same signal as corresponding output lines inside the
cable. Please take this into consideration when configuring the
sense lines (if required).
The AO subsystem also includes input modes, channel
queue, trigger and clocking control.
Interrupt (event) generation: You can use events to provide
gap-free updates of the analog outputs.
Chapter 3: Architecture
There are three update modes for the analog subsystem
• Single update
• Event (interrupt) – based waveform mode
• Continuous pulled-IO waveform mode and auto-
regeneration waveform mode.
The user can define the power-on value of each channel
(the default start-up value is set to zero). The included
utility application “Start-Up Configuration Wizard”
(StartUpState.exe) is installed by the SDK can be used to
modify the start-up states.
Note The Power-On state will be loaded into the DACs with
200 ms maximum delay after the system reset. The calibration
values will be loaded only when PowerDAQ driver is loaded
and up to +/-30 mV offset is possible on the outputs during
the system boot process.
21
Page 30
Chapter 3: Architecture
Note The quad output DACs has current limitations. Only
one output of each quad can be continuously shorted to
ground. Two, three and even four channels shorted to ground
MUST NOT exceed five seconds.
Analog Output Mode
Single Update
The PowerDAQ AO boards operate with either a singleupdate or streaming (waveform) output configuration.
Single-update mode allows direct write access to any of the
16-bit DACs of the PowerDAQ AO board. The update
frequency is at least 1kHz for the single update mode and
can be as high as 15KHz in real-time operating
environments. The single update speed is dependent on your
PC system speed.
Note There is a special sub-mode of the single update mode
when all or selected DAC’s outputs are updated
simultaneously.
22
Event-based Waveform
Event-based waveform mode allows continuous waveform
generation and is not limited by the amount of data. Each
time the DSP based FIFO is ½ full an interrupt is fired to
request additional data to be sent to the board. The
PowerDAQ advanced buffering mechanism hides those
interrupts from the user and allows you to work with big
output arrays logically divided by frames. The end of each
frame can generate an event, which will request more data
from the application. Complete information on the
PowerDAQ advanced circular buffer (ACB) can be found at
www.POwerDAQ.com
Note If the on-board FIFO is empty or the last value is
outputted, the board will continue outputting the last DC
value.
Page 31
Chapter 3: Architecture
Auto-regeneration Waveform (circular waveform)
Auto-regeneration waveform mode can be used to create
fixed length waveforms without any host intervention of
user software after the subsystem has initialized. An
application writes data to the buffer of the PowerDAQ AO
board and each time the end of buffer is reached, it starts
to resend the same buffer again. Note, that 2048 samples
can fit into the on-board DSP memory and auto
regeneration of up to 2048 samples will not require any
intervention of the host PC.
Channel List
There are two ways do define a Channel List for the
PowerDAQ AO board. First, when the output data and
channel number are combined together to provide the
output channel selection. In this situation, the lower 16 bits
are data, the following upper 8, the channel number and
special flags (see the picture below).
This mode supports update rates up to 455KS/sec
31 23 15 0
Not used 16-bit output data
Bits 16-20 are used to define the output channel number on
a PD2/PDXI-AO-8[16][32] board.
Bit 21, when set is used as a Write and Hold Flag – this is
used to write data to the DAC WITHOUT updating it on a
PD2/PDXI-AO-8[16][32] board.
Bit 22, when set is used as an Update All Flag – all DAC’s
will be updated by the previously written data on a
PD2/PDXI-AO-8[16][32] board.
PD2-AO-96 board only:
Bits 16-22 are used to define the output channel number on
PD2/PDXI-AO-8[16][32] boards.
Flags,
23
Page 32
Chapter 3: Architecture
Bits 21,22,23 when all set together are used as a Write and
Hold Flag – written to DAC’s data with this bit set will not
update output.
Bits 23, when set is used as Update All Flag – all DAC’s will
be update by previously written data.
This is the default configuration, which provides an
unlimited channel list length.
Another way to define the channel list is a series of
continuous channel numbers(1/2/4/8/16/32/64), up to the
number of ports available on the AO board, starting at any
channel. For example, the PD2-AO-32, channels 0 through
15 can be specified as a channel list of channels to be
updated in Event-based Waveform Mode and the remaining
channels can be used in Single Update Mode.
This mode is called DMA-based update mode and supports
output rates up to 1.6 MS/sec.
Note There is a dedicated function in the PowerDAQ API
called _PdAO32SetUpdateChannel which can be used to
specify the update channel number. Any write to this channel
will force the update of all DAC’s.
24
Page 33
Digital Output Subsystem
There are eight static digital outputs on the PowerDAQ
analog output board. They are TTL/CMOS output level
compatible, 2000V ESD protected. Due to the static nature
of the outputs they can be updated at any time without any
limitations. Digital outputs provide high current compatibility
(-32/64 ma), which support drive relays or these lines can
be used for control applications.
Digital Input Subsystem
There are eight static digital inputs on the PowerDAQ analog
output board. They are TTL/CMOS input level compatible,
2000V ESD protected. Due to the static nature of the inputs
they can be read at any time without any limitations.
Chapter 3: Architecture
Counter/Timer Subsystem
Depending on your PowerDAQ AO operation mode, the
board can support up to the three DSP based 24-bit
counter/timers with a maximum count rate up to 33 MHz
for 66MHz DSP and 50MHz for 100MHz DSP (PDXI-AO
only) for an internal base clock and 16.5 MHz/25MHz for
the external clock. The minimum count rate is 0.001 Hz for
the internal clock and no low limits for the external clock.
Note For all waveform modes, only Timer0 and Timer1 are
available for use.
Programming of the counter/timer subsystem of the PD2AO board requires a minimal understanding of the Triple
Timer Module of the Motorola 56301 DSP. For this
information please refer to the
Manual
(Motorola P/N DSP56301UM/AD).
Motorola DSP 56301 User
25
Page 34
Chapter 3: Architecture
Each timer can be used for internal or external clocking and
can interrupt the on-board DSP after a specified number of
events (clocks) or signal an external device after counting
internal events. Each timer can also be used to trigger DMA
transfers after a specified number of events (clocks) have
occurred. Each timer connects to the external world through
one bi-directional pin TIO that is 7kV ESD protected. When
TIO is configured as input the timer functions as an external
event counter or can measure external pulse width/signal
period. When TIO is used as output, it functions as a timer,
watchdog or Pulse Width Modulator.
Some common timer/counter/output functions that
microprocessors require are:
Real time clock,
Event counter
Digital one-shot
Programmable rate generator
Square wave generator
Binary rate multiplier
Complex digital wave form generator
Complex motor control
26
Note Each counter is a 24-bit count-up counter
After power-up, the count value and output of all counters
are set to zero
Each counter must be programmed before it can be used
Unused counters need not to be programmed
Use the PowerDAQ API to program counters.
Each counter is fully independent of the others. Only
prescaler, when used, is a common part of the counter-timer
subsystem. Each counter may operate in a different mode
Page 35
Calibration Subsystem
The calibration subsystem is used to calibrate each analog
output zero offset (with 150-microvolt accuracy) and output
range (PD2-AO only). The calibration data is stored in the
on-board EEPROM. Additionally a PowerDAQ AO board
provides an application for the user to configure the startup output value of the any DAC. This value will be loaded
immediately after a system reset or power-on with 200 ms
maximum latency.
DSP Processor
All PowerDAQ AO boards are based on the Motorola 56301
DSP. This is a 24-bit 66/100 MHz processor with an
integrated PCI interface. The PCI interface implements the
PCI Local Bus Specifications so the board is fully autoconfigured (base address, interrupt).
When the PowerDAQ software is loaded, the PowerDAQ AO
firmware is downloaded to the DSP via the PCI bus. This
firmware contains all the code necessary to communicate
with the board subsystems and the host PC driver.
Chapter 3: Architecture
Note The drivers from the PowerDAQ web site always
contain the latest versions of the DSP firmware.
Note Custom programming of the DSP is not available with
the standard PowerDAQ AO product. However, should you
require DSP processing, please contact the factory.
PCI Bus Interface
The PowerDAQ AO boards communicate via the PCI bus. The
PCI bus interface is embedded in the Motorola 56301 DSP.
On power up, the host PC automatically configures the
boards base address and interrupt resources.
27
Page 36
Timing and Control
The PowerDAQ AO clocking and triggering features are
extensive and can be configured in various different ways.
Analog Output Clocking
Clocking comprises of two input signals:
1. Clock In – used to clock analog output channels in
channel list.
2. Trigger In – used to start/stop acquisition
.
You must load the channel list prior to starting this
operation.
Clocking can be controlled by:
Software Strobe
Internal Clock (DSP)
External Clock
Chapter 3: Architecture
28
Universal External Interrupt/Clock/Synchronization Inputs
Note You can only use these lines for Analog Output
Clocking OR Triggering
Triggering is configured as follows:
Use the IRQB pin to asynchronously update all DACs.
Use the IRQC pin to supply your external trigger source.
Trigger modes:
Start trigger (acquisition starts on rising edge of the trigger
signal)
Stop trigger (acquisition stops on rising edge of the trigger
signal)
Trigger lines should be pulled-down to ground via 4.7Kohm
resistors.
Page 37
Chapter 3: Architecture
Synchronizing two or more boards
Note Using the PowerDAQ AO control panel application,
please ensure the software driver recognizes the two or more
PowerDAQ AO boards. No custom synchronization cables are
required – all connections can be made directly on the screw
terminal. PDXI-AO boards provides a special configuration
program PDXICFG.EXE that allows synchronize boards via the
PXI bus extension. This feature is not available in standard
Compact PCI chassis.
If internal connection between multiple boards is required,
the following connections should be made (PD2-AO boards
only):
The PowerDAQ PD2-AO J2 internal connector has a TMR2
Clock I/O pin. You can connect this pin to the TMR2 pin of
the next board you wish to synchronize acquisition. It is
preferable to use a 100-200 Ohm series resistor for the clock
connection.
For a custom cable contact the factory.

API and Third-Party Software
Examples
The PowerDAQ Software Suite API and third party software
drivers support all PowerDAQ AO board features. This
chapter provides an overview on how to use the API calls
and examples using third-party software.
API Function calls
Please refer to PowerDAQ SDK and programmer manual for
the details about Analog Output board programming.
Generally Analog Output subsystem works in the same way
as all other paced subsystems. The following command
sequence should be used to program the PowerDAQ AO
board in a low-level language such as C/C++/VB/Delphi:
• Open Driver. This allows you to check that the driver
is installed properly and started and also gets a
number and parameters of the PowerDAQ boards
installed in the system.
32
• Open Adapter. After the adapter is opened the
PowerDAQ SDK return a special handle that should
be used for all calls referring to a specific
PowerDAQ board installed. This call locks the
specific PowerDAQ board by the specific application.
• Open Subsystem. This call grants access to one of
the available PowerDAQ board subsystems. The
following subsystems can be accessed on a
PowerDAQ Analog Output board: Analog Output,
Digital Input, Digital Output, DSP Counter and
Calibration.
• Work with subsystem. There are two different ways
to use a subsystem – in synchronous and
asynchronous mode.
Page 41
Chapter 4: API and Third-Party Software
• In Synchronous Mode (known as Single Update on
the AO subsystem) there is a set of calls available
which gives direct and immediate access to the
DACs (DIO ports and DSP Timers). Timed access can
be made using the operating system based timing
loops.
• In Asynchronous Mode (which has two sub-modes
on PowerDAQ AO boards – event-based and
regenerate mode) , a dedicated acquisition buffer is
allocated in host PC memory. This buffer is divided
by the number of logical blocks called frames,
usually between 4 and 16 frames should be
allocated. The following steps should be considered
when Asynchronous acquisition mode is used:
# User application uses API calls to allocate the
acquisition buffer and fill it with initial data for all
output subsystems.
# Subsystem configuration word should be assembled
using the API constants provided.
# The user application should define a set of events
from the board. A typical set of events include data
availability events and error events
# Start of asynchronous operation
# WaitForSingleObject operating system function call
or an equivalent should be used to check for events
from the board. It is preferable to put this call into
a separate thread. After an event, the application
should re-initialize it and process the data.
# Terminate asynchronous operation
# Auto-regenerate mode user application can allocate
one or more frames in the buffer, fill it with data
and start acquisition. The PowerDAQ driver will
control event handling and supply more data into
the on-board FIFO as requested. Note, that frame
size cannot exceed 64Mbytes. The size of the
buffer itself is limited by the amount of Physical
memory installed on your PC.
33
Page 42
Chapter 4: API and Third-Party Software
• Close subsystem. When the application closes the
subsystem it’s frees-up resources.
• Close adapter. After the adapter is closed it is
accessible from other applications.
• Close driver.
API Examples
The PowerDAQ Software Suite contains a complete set of selfdocumented examples dedicated to PowerDAQ AO boards
programming. The best way to write your own program is to use a
ready-to-run example and modifiy it as required by your application.
The examples are available in the following languages:
C/C++/Delphi/VisualBASIC:
• Single Update Example (Separate example available for the
PD2-AO-96/16 board)
• Buffered output Example (Event-based)
Please refer to the example sources for extensive programming details.
All examples are located in
<Program Files
Dir>\PowerDAQ\SDK\Examples\<Language>\<Example>
Third-party examples
All third-party drivers, supplied by OMEGA include a set of examples,
which support all of the PowerDAQ Analog Output board features.
They are usually installed during the SDK installation process into the
folders defined by third-party software vendors. Please refer to the
readme file of the SDK version to find an exact location of the
examples you need.
