Overview

DaqView is a 32-bit Windows-based data acquisition program that can be used to operate DaqBooks,
DaqBoards, Personal Daq/3000 Series devices, and a variety of related data acquisition products. The
application was designed for ease-of-use; and no programming expertise is required.

When applicable to your device DaqView allows you to:

• Set up system parameters (select channels, gains, transducer types, etc) to acquire data.

• Save data to disk and transmit data to spreadsheets and databases.

• Automatically re-arm the trigger function and save data in new files as needed.

• Configure and operate DBK option modules.

• Configure the counter/timer into one of three modes for measuring frequency, totalizing, or

generating pulse trains.

• Output analog data, including waveform generation.

• Display digital I/O.

• Allow data to be viewed in a real-time Scope Mode.

A Post Acquisition Data Analysis Program, if installed, can be launched from DaqView to view, measure,
and edit data. eZ-PostView is an example of a post data acquisition analysis program.

ViewXL is a Microsoft Excel-based add-in which enables DaqView to take advantage of the features of
Excel. The application is discussed in Appendix A of this manual.

Before Using DaqView

Before using DaqView you should be aware of the following points:

The degree of DaqView functionality is dependent upon the data acquisition device. For

example, analog output channels will only be represented for devices capable of analog
output and DBK expansion will only be permitted for devices that accept DBKs. Thus it is
important that you understand your hardware’s capabilities by reviewing the applicable user
manual. PDF versions of the manuals are included on the installation CD.

In order to make DaqView more user-friendly, when a feature does not apply to your system

the affected GUI (Graphical User Interface) aspects will be grayed-out or hidden.

DaqView can only be used with one primary data acquisition device [and its associated

DBKs] at a time.

grayed-out.

Functionality Differences amongst Devices

Device functionality is paralleled in DaqView. If a device does not support a particular function the related
software feature will be disabled (grayed-out), or will not be visible. Before using any of the information
in this document you should be aware as to whether or not it applies to your specific hardware.

With very little exception the following screen images were taken from DaqBoard/2000 Series devices.
The available toolbar controls and spreadsheet information are virtually identical for other devices.

A synopsis of functional support is provided just to the right of each screen.

The DaqView main window will
appear much as it does to the left
for Daq devices that have:

Analog Input Channels
Digital I/O Channels
Counter Inputs
Timer Outputs
Analog Output Channels

When your device does not have one
or more of these functions, then
those that do not apply will be either
grayed-out or simply won’t be
displayed.

Consult your hardware user
documentation in regard to features
that apply to your specific device.

A DaqView Walk-Through

From Opening DaqView to DBK Setup

The following walk-through is intended to
provide quick familiarization with DaqView.

(1) Open DaqView. If your Daq device or DBK

signal-conditioning units are not connected you
can select Simulated Instrument as your device.

(2) From the File menu, select Authorization.

If prompted to enter an Authorization Code,
complete step 3. The code, if applicable to your
application, will be found on a separate sheet. If
you are not prompted to enter a code skip to step

4.

(3) Enter the code and then click the
<Apply Code> button.

If you have no Authorization Code you can click
the <Start 30-Day Trial> button to enable a
temporary version of DaqView. Note that you can
also order DaqView upgrades “online.”

(4) To familiarize yourself with the three tabs on

the DaqView main window, click and observe
each [Channel Setup, Acquisition Setup, and
Data Destination].

The Channel Setup tab displays a spreadsheet for
viewing and changing the configuration of analog
and scanned digital input channels. Each row is
dedicated to a single channel.

Note that your actual screens may appear slightly
different than shown in the example screen shots.

DaqView & ViewXL User’s Guide 908394 A Tour of DaqView 2-5

The Acquisition Setup tab displays a window that
includes parameters for triggering and configuring
the scan. These settings are used when an
acquisition to disk is started with the toolbar’s
<Acquire> button. When the trigger is satisfied,
scans are collected at the selected scan frequency
and stored to disk in the designated file.

Note that these parameters cannot be altered while
an acquisition is in progress.

The Data Destination tab provides a means of
designating the desired file formats and directories
for acquired data.

From the Device menu, select
Configure Hardware Settings.

The Configure System Hardware dialog box will appear. (See following figure.)

Whenever expansion cards are added you must update the
Configure System Hardware dialog box.

Configure System Hardware Dialog Box

On the left side of the box select any channel’s pull-down box to reveal the external connection options.
Besides the default [Direct Signal Connection] you can choose among the DBK option cards and
modules. The lower left-hand section of the dialog box includes an Advanced Features panel. Note
that the buttons in this panel, <Counters> and <Setpoints>, will only be enabled when applicable to your
device.

The right side of the screen sets up digital connections, if your Daq device is so equipped.
In our tour of DaqView, click <OK> at this time to return to the DaqView main window.

Reference Note:

Chapter 3 is dedicated exclusively to the Configure System Hardware dialog box and
provides examples of Analog DBK and Digital DBK setups.

DaqView & ViewXL User’s Guide 908394 A Tour of DaqView 2-7

Channel Readings, Acquire, and Post-Acquisition Buttons

Select the <Channel Readings> button. If in the Simulated Instrument mode, the
Reading column of the Analog & Scanned Digital Inputs spreadsheet will display
simulated data. Selecting the <Channel Readings> button again freezes the Reading
column display. If working hardware is connected, the readings will quantify actual
signals.

Additional information is provided in Chapter 4 under, Toolbar Items, Channel Setup

Buttons.

The Acquire selection activates an acquisition of data to file. The Event option under the
Trigger Setup portion of the Main window determines when the Acquire process is

initiated. The Event selections are detailed in the Acquisition Setup section of this
chapter. After Acquire is selected, the process is automatic beginning with the DaqView
Armed screen. This screen posts the Trigger Armed time as well as the Trigger Event
information. The Acquire process makes use of the Data File Setup parameters to
format data collection.

Once the Trigger Event occurs, the DaqView Triggered screen appears. This screen
allows you to witness the data sampling parameters you set in the Main window prior to
initiating the Acquire process as well as the progress of the d ata acquisition.

If file conversion is selected, the Acquire process concludes by converting the generated
.BIN file from binary to ASCII data. The resulting file is saved under a user-specified
directory and file name or as a default under the DaqView subdirectory as DAQV.TXT.
This .TXT file is available for data processing or analysis by various software packages
such as ViewXL.

This button is used to launch an independent post-data acquisition program, such as
eZ-PostView. For details, refer to the eZ-PostView PDF document that is included on
your data acquisition CD. You can access the document via the <View PDFs> button
located on your CD’s intro-screen.

Whenever expansion cards are added you must update Configure System Hardware.

Overview

For proper operation most of the DBK options must be configured, both physically on the DBK, and in the
Configure System Hardware dialog box.

“Analog Input” type DBKs will be under the P1 section of the screen, “Digital Input” DBKs will be under
the P2 section.

Prior to setting up a DBK you should review the applicable individual DBK section to ensure that the DBK
option is physically set as desired. Note that certain DBKs do not require configuration.

Understand your DBK’s physical configuration before attempting to set the device in
the Configure System Hardware dialog box. For example, if you were configuring a
DBK45 in DaqView, you would need to know the physical setup of rotary switch SW6
to properly set the address. To expedite the configuration, it is a good idea to have the
identity and setting information ready for each DIP-switch, rotary switch, and jumper,
as applicable.

Setting Up Analog DBKs

Complete the following steps to set up analog DBKs in DaqView.

1. From DaqView’s main screen, pull down the Device menu, and select “Configure Hardware

Settings.”

Selecting Configure Hardware Settings from the Device Pull-down Menu

DaqView & ViewXL User’s Guide 886994 Configure System Hardware 3-1

The Configure System Hardware screen appears, showing the channel assignments.

Configure System Hardware Screen

The DBKs typically have a channel address set physically on the device, by either a
switch or a header. The channel designated in software must agree with the hardware
setting. Thus, in step 2 below, Channel 0 will only be used to select a specific DBK when
that DBK is physically set for Channel 0. Refer to the specific DBK section for more
information, if needed.

2. Under Analog I/O Option Cards External Connection, select the expansion down-arrow for the

chosen Daq Device channel, for example, P1 Channel 0. A “drop-down” will list the available
analog DBK options.

An alternative to using the expansion down-arrow to access the external connection drop­down list, is to click within the text box. For example, in the following figure, after clicking
on P1 Channel 0’s “Direct Signal Connection” text, the drop-down list appeared.

Configure System Hardware Screen Showing Analog I/O Option Cards,

External Connection, P1 Channel Pull-down List for Channel 0

3-2 Configure System Hardware 886994 DaqView & ViewXL User’s Guide

3. Select the applicable DBK card from the drop-down list.

If the card has jumper or switch setups that need to be set in DaqView, a related dialog box will
appear. Three extracted examples follow: (a) Switch Settings: S1 Sub Address, (b) Switch Settings:
SW6 (rotary), and (c) Shunt Settings: JP16 (3-pin shunt).

Examples from Setup Dialog Boxes

4. Set the software DIP-switch settings, shunt-settings, and so forth to match the hardware settings on the

actual DBK(s).

5. When all the channels and sub-addresses are set correctly, select OK to return to the DaqView main

screen.

6. From DaqView, complete the channel setup, acquisition setup, and data destination setup for each of

the new DBKs.

This completes the software setup for analog DBK options, with excep tion of th e following special case

scenario pertaining to DaqBook/2020.

It is possible to have a situation similar to that
shown at the right where we see that the
descriptive text for External Connection P1
channels 0 and 1 is grayed-out (see area “A”).
However, the P1 Channel numbers are clearly
visible.

The reason, in this instance, is that we are using a
DaqBook/2020. For that device “P1-0” is being
used by the device’s internal circuitry for 16
differential voltage channels. These are the Direct
Channels that are listed on the main spreadsheet,
i.e., CH0 through CH15.

In addition, the device’s “P1-1” is being used by
its own set of 16 thermocouple channels. These
are the TC0 through TC15 Direct Channels listed
on the main spreadsheet.

In addition to indicating pre-assigned channels, the

Configure System Hardware screen may display a
device-dedicated GUI panel similar to that shown

at the right (see area “B” in the figure). In this
example [from a DaqBook/2020] checking the box
enables channel P1-2 through P1-15 to be added to
the channel scan list as direct connect channels. In
other words, the channels will appear on the main
window spreadsheet along with the P1-0 and P1-1
direct channels.

Analog I/O Expansion Supported, and

Pre-Dedicated Channels P1-0 and P1-1

In this DaqBook/2020 example analog expansion is
supported. However, notice that the first two
channels (designated by “A” in the figure) are
grayed-out. In this case 2 channels were pre­assigned due to channel circuitry built-into the
device.

DaqBook/2020 uses P1-0 for 16 differential voltage
channels and P1-1 for 16 thermocouple channels.
These 32 channels are built-into the device, as
opposed to being obtained from an external DBK.

DaqView & ViewXL User’s Guide 886994 Configure System Hardware 3-3

Setting Up Digital DBKs

Review the applicable DBK section to ensure that the DBK option is physically set as desired. Note that
certain DBKs do not require hardware or software configuration.

Complete the following steps to set up digital DBKs in DaqView.

1. From DaqView’s main screen, pull down the Device menu, and select

“Configure Hardware Settings.”

Selecting Configure Hardware Settings from the Device Pull-down Menu

The Configure System Hardware screen appears, showing the channel assignments.

Configure System Hardware Screen

DBKs typically have a channel address set on the device, by either a switch or a header.
The channel designated in software must agree with the hardware setting. Thus, in step 2
below, Channel 0 will only be used to select a specific DBK when that DBK is physically set
for Channel 0. Refer to the specific DBK section for more information, if needed.

3-4 Configure System Hardware 886994 DaqView & ViewXL User’s Guide

2. Under Digital Option Cards, select the expansion down-arrow for the chosen Daq Device

channel, for example, P2 Channel 0. A “drop-down” will list the available digital DBK
options.

TIP: An alternative to using the expansion down-arrow to access the external connection drop-
down list, is to click within the text box. For example, in the following figure, after clicking on
P2 Channel 5’s “None,” a drop-down list will appear, like the one shown for Channel 0.

3. Select the applicable digital DBK card.

If the card has jumpers or switches, a related window will appear. Two examples follow. The first is
for DIP-switch and jumper settings for a DBK208. The other is for a DBK25 DIP-switch.

Examples from Setup Dialog Boxes (These vary according to the DBK)

4. If applicable, set the software DIP-switch and other settings (such as jumpers) to match the

hardware settings on the actual DBK(s).

5. After all the settings are confirmed correct, select OK to return to the DaqView main screen.

6. From DaqView, complete the channel setup, acquisition setup, and data destination setup for

each of the new DBKs.

This completes the software setup for digital DBK options.

Enhanced Counter Configuration

If your Daq device supports enhanced counter configuration, for example, your device is a DaqBoard/3000
Series or a Personal Daq/3000 Series device, you can click on the <Counters> button [located in the
“Advanced Features” panel] at the lower left of the Configure System Hardware screen. This brings up the
“Enhanced Counter Configuration Settings” dialog box. From this dialog you can set several different
parameters, independently, for each of the enhanced counters.

pertaining to very fast data acquisition, large data acquisition, high averaging, and
auto-rearm is likely to degrade the performance of meters and the spreadsheet
“readings” display.

Column Description

CH

On

Type

Polarity

The channel number (cannot be changed from this window). This number includes the main channel
number and the expansion board number and channel (if used). Expansion channels are configured
using the Hardware Configuration window described later in this module.

This column allows you to select whether data will be collected from that channel. When a cell or
block of cells in this column is selected, a selection box will appear that allows “Yes” to enable or “No”
to disable the channel. Double-clicking a cell in this column will toggle the channel status. The Edit
menu allows you to Make All Channels Active or Make All Channels Inactive.

This column allows you to set the gain or input type for each channel. The gains and types will vary
among the option cards. A block of cells in this column can be selected for multiple channels with the
same type of option card. Double-clicking a cell will select the next available gain or type.

Note: If one of the P3 counters is active in the scan, and Type is selected for frequency
measurement, low frequency input signals will require a slow scan rate setting for accurate
measurement. For example, for a frequency of 200 Hz, set the Scan Rate (in the Acquisition Setup
window) for 1 scan per second or 6 scans per minute.

This column shows the channel polarity (unipolar or bipolar) for each channel. The polarity can be
programmed here on a per channel basis when using a DaqBook/200, /216, /260 and any DaqBoard
[ISA or PCI type], or a DBK15 Universal Current/Voltage expansion card. When using any other
Daq*s, this column is set in the Hardware Setup window. For selected cells that can be changed, a
selection box will display “Unipolar” or “Bipolar”. Double-clicking in a cell will toggle the polarity. If
the hardware cannot program the polarity, no selection box will be displayed.

Label

Units

This column contains a descriptive name for the input channel. The default label is the channel
number, but it can be changed to any 8 characters and must be unique. This label is used when
selecting a channel in the analog trigger and chart selection lists.

When a Units-cell [or block of cells] is highlighted, unit options can be selected from a pull-down box.

Double-clicking in a Units-cell cycles through the available choices for each of the channel types, as

follows:

o Voltage: V, mV, Mx + b
o Temperature: °C, °F, °R, °K, Mx + b
o Frequency (Enhanced Counter): Hz, Counts, Mx + b
o Period, Pulsewidth, and Timing (Enhanced Counter): Seconds, Counts, Mx+ b

Reading

This column displays the device’s analog or scanned digital input readings. This column cannot be
altered by the user and is enabled by selecting Enable Input Reading Column under the Data menu
or by selecting “Start/Stop All Indicators” under the window menu. This column will update the
readings as fast as the computer will allow. The spreadsheet cannot be altered while the input
reading column is enabled.
