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 
loaded onto your hard drive during software installation.  The default location is the 
Programs directory, which can be accessed through the Windows Desktop.
