Out-of-the-Box Software
I/O Support
In addition to analog input, DaqView lets
you easily set up and configure analog output, digital I/O, and counter/timers prior
to beginning an analog scan sequence.

Digital I/O
Each of the three 8-bit digital I/O ports canbe configured for input or output. DaqView
also allows you to set up and configure up
to 192 channels of digital I/O expansion if
DBK digital options are installed in yoursystem. Signals are updated each time theexecute button is pressed.

Counter/Timers
You can set 5 counter/timers to measurefrequency, totalize pulses, or generate periodic digital outputs. Signals are updated
each time the execute button is pressed.

Analog Output
You can set up the analog outputs as simple
voltage levels or as waveforms. DaqViewlets you draw waveforms, load files containing waveforms, or choose from a variety of
pre-loaded waveform types. The maximum
waveform update rate is dependent upon
maximum rate attainable by the hardware.

Signal Conditioning & Expansion I/O Support
DaqView supports a wide variety of input and output signals
via IOtech’s DBK signal conditioning and expansion hardware
options. These DBK products support various analog and digital
I/O signals from thermocouples and RTDs to accelerometers andstrain gages. DaqView automatically converts readings from theDBK options into real-world parameters such as temperature,displacement, ­frequency, and many other engineering units.
For example, DaqView automatically performs cold-junction

Setpoint Configuration Dialog
DaqView has a new setpoint configuration dialog that allows theuser to configure setpoints for their /3000 Series hardware. The
setpoint configuration dialog allows up to 16 individual setpoints
to be configured. Each setpoint can utilize any valid voltage,digital, or counter input as an input source, and can evaluate thatchannel against configured limit conditions as follows:•Input channel greater than limit•Input channel equal to limit•Input channel less than limit•

Input channel inside high and low limits•

Input channel outside high and low limits•

Input channel satisfies hysteresis criteria

The setpoint configuration dialog also allows configurationof output actions when the input criteria has been met. The
output action can be to drive any of the valid analog, digital,
or timer output ports to a value configured by the user. Referto the /3000 Series for further information on setpoint featuresand operation.

The Setpoint configuration dialog allows the user to configure up to
16 setpoints for their /3000 Series products

Scope & Strip Chart Display
DaqView now has greatly enhanced
scope and strip chart displays including
Analog, Logic, and Counts display modes.
The Analog display modes allow users todisplay analog channels such as voltage,
temperature, and other analog measurements in either a scrolling strip chart orscope format. In a like manner, digital andcounter values can be displayed in strip
chart or scope format by using the Logic
and Counts display modes respectively.

Multiple Analog, Logic, and Counts displays can be viewed concurrently on the same display page

Each display can allow up to 16 channel
traces and up to 4 displays can be added
to the standard display page. An unlimited
number of display pages can be created.
Channels are easy to add to each display bysimply dragging and dropping them onto
the display of choice. A main toolbar allows
easy display manipulation and operationthat includes button controls for acquisition
starting, triggering, and stopping as well
as overall cursor and gridline controls. Inaddition, each display has it’s own toolbarcontrols allowing independent operation

A main status bar indicates overall acquisition status as well as data representation of the ­currently selecteddisplay and cursor.

different fashions so users can compare the results of previous tests
with real-time or newer data to fine-tune their process.
Multiple file sets previously recorded with any particular configuration tree may be brought into the DaqView scope display. Users
can then observe all the channels that were in the file, and eachchannel can be individually selected and put into any plot of theusers choice. DaqView users also may compare data recorded in
the frequency domain with data recorded in the time domain.
Regardless of the domain in which the data was recorded, thelatest version of DaqView converts the time-domain data into
the frequency domain to let users observe the comparison.

The latest version of DaqView now contains features that let users
overlay real-time data with previously recorded data. The data may
have from either recent or older Daq product files, or any other IOtech
product, such as the WaveBook. The overlays may be presented in

Analog Display
The Analog display allows users to display
analog measurement data such as temperature, voltage, strain, and accelerationin an easy to understand format. A statusbar indicates current cursor information as
well as overall Average, Minimum, Maximum, and RMS values for the data in thedisplay. Cursor annotations are available
for easy data interpretation. If dual cursors
are enabled, annotations for differences ofX and Y values are displayed.
The Analog Scope allows users to easily display and analyze analog data such as temperature,
voltage, strain, acceleration, or other analog data

Logic Display

The Logic display allows users to display and analyze digital data in a Logic Analyzer format

digital data that is measured in a synchronous manner to be displayed in a logic
analyzer format. Each bit of the digital port
is displayed as a separate trace allowing users to easily analyze digital data. It’s value
is indicated as either High or Low. A statusbar indicates current cursor informationfor each bit as well as overall value of theport in a Hex format. Duty cycle information is also included. Cursor annotations
are available for easy data interpretation.
If dual cursors are enabled, annotations
for duty cycle between the cursor values
are displayed.

Excel® Integration

There are several types of display modes available for the Analog,Logic, and Counts display types.

DaqView provides complete data acquisition functionality andis seamlessly integrated into Excel’s tool palette. Excel is an ideal
tool for test engineers because it provides a variety of graph andcharting functions for presenting data in a graphical format, as
well as mathematical and analysis functions such as FFTs. Excel’s
ability to retrieve and manipulate previously acquired data in aspreadsheet format and DaqView’s advanced data acquisitionfunctions form a comprehensive data acquisition solution.

•Scrolling Strip Chart continuously scrolls new data to theright while old data falls off the display to the left•

Scrolling Overlay Chart will continually overlay the oldest
data with newest data on the display•Scrolling Block Chart will add new data from the left until thedisplay is filled and then clear the display and begin again
displaying new data from the left•

Scope Display will not display data until the entire acquisition
is complete and then render all the data on the display

Scrolling chart displays allow data to be displayed as the acquisition runs. This mode allows real time interpretation of slower
moving signals such as temperature. The Scrolling chart displays
each have settings allowing the total display time as well as history
settings to allow the user to scroll back and view previously collected data. The Scope display can be used to analyze fast moving
or transient signals in display frames. The Scope display mode isutilized for advanced signal analysis found in DaqView.

DaqView seamlessly executes from within Excel’s tool paletteWith DaqView there is no limit to the number of displays or­display pages that can be added thus allowing hundreds ofacquired channels to be displayed and analyzed. The uniquedisplay page design allows numerous display pages to be added
and managed. In addition, each display page can have a nearly
unlimited number of displays that can be scrolled through by
the user.
