Daq Systems, the Modular Concept
Daq equipment and software form a modular, interrelated family of products that provide great flexibility
in data acquisition system design. This flexibility allows for the development of custom systems that are
unique to the user, and which can be optimized for his or her specific application needs. With the Daq
product line, system expansion or redesign can typically be accomplished with relative ease.
Primary Acquisition Device. This is the main data acquisition device, e.g., a DaqBook or
DaqBoard. These devices provide a vital data conversion and communications link between the data
source of transducers and signal conditioners and the data processor of the host computer. Note the
DaqBoards can be one of three types: (1) ISA, (2) PCI, or (3) compact PCI (cPCI). The DaqBoards
covered in this document are of the ISA type.
DBK Option Cards and Modules. Over 35 DBK cards and modules (the number is constantly
growing) provide various types of signal conditioning and system expansion. Note that certain DBK
modules exist for the purpose of supplying power to other members of the acquisition system. The
DBK options are discussed in a DBK Basics document module and in the detailed DBK Option
Cards and User’s Manual (p/n OMB-457-0905).
Reference Note:
DBK options are discussed in the DBK Option Cards and Modules User’s Manual
(p/n OMB-457-0905). As a part of product support, this manual is automatically loaded
onto your hard drive during software installation. The default location is the Programs
directory, which can be accessed through the Windows Desktop.
Software. DaqView out-of-the-box software provides a graphical user interface with easy to read
spreadsheet formats for viewing channel data, as well as a choice of analog, digital, and bar-graph
meters. Waveform analysis can be performed, when applicable. A product support option, included
on the data acquisition CD, provides a means of performing post data analysis. More information is
included in the software-specific PDF documents that are installed on your hard-drive as a part of
product support.
In addition to the included out-of-the-box software, Daq products can be controlled via user-written
custom programs through Applications Program Interface (API). Several languages are supported,
e.g., C/C++, VisualBASIC, Delphi.
Reference Note:
Programming topics are covered in the Programmer’s User Manual
(p/n OMB-1008-0901). As a part of product support, this manual is automatically

1-2 Overview
10-29-02 OMB-Daq Systems
DaqBooks and DaqBoards
Daq products connect to one or more DBKs on their signal input side and a computer on their output side.
Each type of Daq device connects to the computer in a different way:
The DaqBook is an external module that connects to a computer’s enhanced parallel port (EPP)
interface or PC-Card link.
The DaqBoard [ISA type] board is an internal card that plugs into an ISA-bus slot within a
computer.
Features common to the Daq products include:
100-kHz channel-to-channel scan and gain switching (10 µs);
200-kHz for DaqBoard/2000 Series and DaqBoard/2000c Series Boards.
512-location sequence memory that can be loaded with any combination of channels and gains.
Ability to access up to 256 different channels of DBK signals while maintaining the channel-to-
channel scan rate. The DBK expansion options can accommodate mixed-signal inputs from
thermocouples and RTDs to isolated high-voltage inputs and strain gages.
Ability to handle 8 differential or 16 single-ended signal inputs without DBK expansion units.
Ability to handle fixed digital I/O up to 4 TTL lines in and 4 TTL lines out (accessible only if no
analog expansion cards are in use).
The following table lists various features of DaqBooks and ISA-DaqBoards.

Using DBK Cards and Modules for Signal Conditioning
The DBK signal-conditioning cards and module are designed for use with DaqBooks, LogBooks, and
various types of data acquisition boards, i.e., ISA, PCI, and compact PCI (cPCI) types. The DBKs perform
best when used with an acquisition device that can dynamically select channel, gain, and range. DBK
cards and modules with dynamic channel and gain/range selection allow for high channel-to-channel scan
rates with a variety of transducers.
OMB-Daq Systems 10-29-02 Overview 1-3
DBK output signals can be bipolar, e.g., -5 to +5 V, or unipolar, e.g., 0 to 10 V. The user can select a
range of relevant values to correspond to the lowest signal (e.g., -5 or 0 V) and the highest signal (e.g., 5 or
10 V) signal. This type of range selection guarantees the highest resolution in 12-bit or 16-bit conversion.
DBK modules share the same footprint as the DaqBook and a typical notebook PCs; allowing for
convenient stacking. The majority of these modules have their own power supply; however, several
options exist for packaging and powering the DBKs.
Reference Note:
DBK options are detailed in the DBK Option Cards and Modules User’s Manual
(p/n OMB-457-0905). As a part of product support, this manual is automatically loaded onto
your hard drive during software installation. The default location is the Programs directory,
which can be accessed through the Windows Desktop.
Daq Software
The Daq devices have software options capable of handling most applications. Three types of software are
available:
ready-to-use graphical programs, e.g., DaqView, DaqViewXL, and post acquisition data analysis
programs such as PostView, DIAdem, and eZ-PostView
drivers for third-party, icon-driven software such as DASYLab and LabView
various language drivers to aid custom programming using API
Ready-to-use programs are convenient for fill-in-the-blank applications that do not require programming
for basic data acquisition and display:
DaqView is a Windows-based program for basic set-up and data acquisition. DaqView lets you
select desired channels, gains, transducer types (including thermocouples), and a host of other
parameters with a click of a PC’s mouse. DaqView lets you stream data to disk and display data
in numerical or graphical formats. PostView is a post-acquisition waveform-display program
within DaqView.
DaqViewXL allows you to interface directly with Microsoft Excel to enhance data handling and
display. Within Excel you have a full-featured Daq control panel and all the data display
capabilities of Excel.
Post acquisition data analysis programs, e.g., PostView, DIAdem, and eZ-PostView, typically
allow you to view and edit post-acquisition data.
The Daq Configuration control panel allows for interface configuration, testing, and
troubleshooting.
Each Daq system comes with an Application Programming Interface (API). API-language drivers include:
C/C++, Delphi, and Visual Basic. The latest software is a 32-bit version API.

Configuration and change the DaqBook configuration settings to those that work properly.
Test results have two components: Resource Tests and Performance Tests.
Resource Tests
Resource tests are intended to test system capability for the current device configuration.
These tests are pass/fail. Resource test failure may indicate a lack of resource
availability or a resource conflict.
Base Address Test – Tests the base address for the selected parallel port. Failure of
this test may indicate that the parallel port is not properly configured within the
system. See relevant operating system and computer manufacturer’s documentation
to correct the problem.
Interrupt Level Test – Tests the ability of the parallel port to generate interrupts.
Failure of this test may indicate that the parallel port may be currently unable to
generate the necessary hardware interrupt, while other parallel port devices may
work OK in this mode. Some parallel port devices (such as printers) do not require
interrupts to work properly. See relevant operating system and computer
manufacturer’s documentation to correct the problem.

Performance Tests
Performance tests are intended to test various DaqBook functions with the current device
configuration. These tests give quantitative results for each supported functional group.
The results represent maximum rates at which the various operations can be performed.
These rates depend on the selected parallel port protocol and will vary according to port
hardware capabilities.
ADC FIFO Input Speed – tests the maximum rate at which data can be transferred
from the DaqBook’s internal ADC FIFO to computer memory through the parallel
port. Results are given in samples/second, where a sample (2 bytes in length)
represents a single A/D value.
Digital I/O Input Speed – tests the maximum rate at which DIO input data can be
transferred from the DaqBook’s Digital I/O ports to computer memory through the
parallel port. Results are given in bytes/second.
Digital I/O Output Speed – tests the maximum

DaqBook/260, which is 11 × 13 × 3.5 inches. DaqBooks attach to a host PC’s parallel port via a 25-wire
parallel port cable and can transfer data bi-directionally at up to 170 Kbytes/s for a standard printer port
(SPP) and up to 800 Kbytes/s for an enhanced parallel port (EPP). Data is stored in the PC’s memory and
hard drive, not in the DaqBook.
DaqBooks can be powered from a suitable AC-to-DC power adapter, a 12 V car battery, or a rechargeable
NICAD battery module. This power flexibility is ideal for portable and remote data acquisition, such as
automotive and aviation in-vehicle testing.
Output power from the DaqBook’s P1 connector includes: +5 VDC via pin 1, +15 VDC via pin 21, and
-15 VDC via pin 2.
Reference Notes:
The section, External Analog Expansion Power (JP1), explains how to set JP1, based on
power use in the system.
DaqBooks have capabilities which, at one time, could only be met by using several plug-in DAS boards.
All DaqBooks provide 16 analog inputs, and can be expanded up to 256. In addition, each model has 2
analog outputs, and at least 4 digital I/O channels. Some models have built-in expansion slots; other
models have additional digital I/O and counter/timer capabilities.
DaqBook Differences
While all DaqBook models are closely related, the following should be noted.
DaqBook/112 and DaqBook/216 provide 1 slot for an expansion DBK card.
DaqBook/100, DaqBook/120, and DaqBook/200 do not have an expansion slot, but do have
24 general-purpose digital I/O channels (expandable up to 192), 16 high-speed digital inputs,
and 5 frequency/pulse I/O channels.
DaqBook models /120, /200, and /260 have EPP (Enhanced Parallel Port) capability.
DaqBook/260 has 3 expansion slots for DBK cards.
DaqBook/100, DaqBook/112, and DaqBook/120 are 12-bit.
DaqBook/200, DaqBook/216, and DaqBook/260 are 16-bit.

Performance Factors
DaqBooks are flexible when it comes to analog input capabilities. The A/D maximum sample rate is
100 kHz (divide by number of channels for scan rate) with a 16-channel multiplexer and a programmable-
gain input amplifier. Users can expand channel capacity to 256 analog inputs via expansion modules for
multiplexing RTDs, thermocouples, strain gages, anti-aliasing filters, and simultaneous sample and hold
amplifiers.
Expansion cards and modules attach to the DaqBook’s 37-pin P1 I/O connector.
Reference Note: Connector Pinouts begin on page 3-8.
The DaqBooks can perform 100 kHz scan sequences with programmable delays from 10 µs to 10 hours.
The 100 kHz conversion rate fixes the time skew between channels at 10 µs. The 512-location scan
sequencer allows selection of the input amplifier gain for each channel. DaqBook models /100, /120, /200,
and /260 can each scan 16 digital inputs in the same sequence used for analog inputs; such inputs are thus
time-correlated. Optional simultaneous-sample-and-hold (SSH) cards enable DaqBooks to instantaneously
sample up to 256 channels. Scanning and timing specifications are met, even when a DaqBook system
includes a full complement of expansion modules. All types of transducers are scanned within the same
scan group, and with no intervention from the host PC.
DaqBooks offer a wide selection of triggering capabilities. Scans can be triggered by software, a TTL
signal, or a level of analog input [including slope]. The analog input trigger is hardware-based and
minimizes trigger latency to less than 10 µs.

Jumpers
Proper installation requires that several jumpers and switches be set correctly for your application. These
jumpers and switches are located inside the DaqBook enclosure and possibly on your DBKs. Jumpers for
the various DaqBook models are configured similarly except for the jumpers’ relative locations. Silk-
screening on the motherboard identifies jumpers and switches. Note: Even if using the default settings,
you should verify actual jumper positions.
The DaqBook configuration jumpers include:
JP1 - External Analog Expansion Power; default is Analog Option Card Use
JP2 - DAC Voltage Reference; default is DAC0 and DAC1 internal reference with SSH
JP3 - Unipolar/Bipolar; default is bipolar (Note 1)
JP4 - Differential/Single Ended; default is single ended (Note 1)
JP5 - Time Base; default is 1 MHz
JP6 - Watchdog Timer; default is Watch Dog timer disabled
JP7 - Reserved for factory use.
Note 1: DaqBook/200, DaqBook /216, and DaqBook /260 do not have JP3 and JP4 jumpers.
For these products the related settings are made via software.
Location of DaqBook Jumpers
External Analog Expansion Power (JP1)
This 4×2 header (JP1) has 3 possible settings. If analog option cards (DBKs) are used, the JP1 pins are set
to provide +15 and -15 VDC to the cards. If such cards are not used, the counter/timer CTR0 is available,
and JP1 must be set accordingly. The default setting is for use of analog option cards.
CAUTION
If using a DBK32A Auxiliary Power Supply or a DBK33 Triple-Output Power Supply
Card, the JP1 shunt jumpers must be entirely removed. Placing the jumpers on
-OCTOUT and -OCLKIN will damage the 8254 timer chip.
