should skip directly to chapter 2.
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, DaqBoard, DaqLab, DaqScan, or Daq PC-Card. 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.
• 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 the DBK Option
Cards and User’s Manual (p/n 457-0905).
Note: Only passive DBKs, such as the DBK1 BNC module, the DBK11A screw terminal
card, and the DBK40 BNC analog interface, can be used with a Daq PC-Cards.
Reference Note:
DBK options are discussed in the DBK Option Cards and Modules User’s
Manual (p/n 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++, and VisualBASIC.
Note that third party icon-driven software, such as DASYLab and LabView, can be used
with the Daq devices.
DaqScan/2000 Series 949595 Daq Systems 1-1
DaqView and DASYLab can only be used with one DaqScan/2000
Series device at a time.

DaqScan/2000 Series 949595 Daq Systems 1-3
Using DBK Cards and Modules for Signal Conditioning
The DBK signal-conditioning cards and modules are designed for use with DaqLab, DaqScan,
DaqBook, LogBook, and various data acquisition boards, i.e., ISA, PCI, and compact-PCI
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.
Note: Only passive DBKs, such as the DBK1 BNC module, the DBK11A screw terminal card,
and the DBK40 BNC analog interface, can be used with Daq PC-Cards.
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 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

• Scan Sequencing. Each DaqLab/2000 Series device has a scan sequencer that can
select up to 16384 channel/range combinations. Scan rates are programmable on a
per channel basis to 5 µs/channel, 10 µs/channel, or 1000 µs/channel.
Note: Inputs can be measured at the 5 µs/channel rate. However, some DBK
expansion options require more settling time and can be measured at the
slower rate of 10 µs/channel or 1000 µs/channel. All types of measurements
can be mixed within the scan group.

System Applications
In addition to basic applications that make use of a DaqScan model’s built-in I/O, a wi de
variety of signal conditioning and expansion options make additional applications possible.
Each of the following sample systems are obtained by using a DaqScan along with one or
more DBK options. The applications, which are only briefly discussed, include:
• High Channel Count Thermocouple Measurements
• High-Isolation Voltage & Thermocouple Measurements
• Isolated Digital I/O
• High Speed Voltage Measurement
• Multifunction I/O
High Channel Count Thermocouple Measurements
When combined with 56-channel DBK90 thermocouple input modules, DaqScan can measure
up to 896 channels of thermocouple (TC) input. Any TC type can be installed into any channel
using standard mini-TC connectors. DBK90’s built-in cold junction compensation (CJC)
coupled with the software’s TC conversion algorithms make temperature measurements easy.
Note that thermocouples are measured at a rate of 1 ms/channel in DBK90 based systems.
High-Isolation Voltage & Thermocouple Measurements
DaqScan units can be combined with DBK207/CJC™ options to create an isolated system
capable of measuring up to 256 channels of voltage, thermocouple, RTD and strain gage
inputs. All input channels can be scanned up to 200 kHz, and are isolated by 500V from other
channels and from system common. Any combination of input signals is possible by selecting
the appropriate 5B signal conditioning module for the DBK207/CJC.
Isolated Digital I/O System
When the DaqScan/2002 is combined with a DBK208 or DBK210, up to 256 channels of
isolated digital I/O are possible, capable of controlling AC or DC voltages up to 250V, or
sensing the presence of AC or DC voltages. All channels are isolated from one another and
from the system by up to 500V. Inputs can be scanned in 16-bit increments at speeds up to
200 Kreadings/s.
High-speed Voltage Measurement System
The DaqScan/2005 can be combined with DBK85 16-channel voltage input modules. This
creates a 5 µs/channel voltage measurement system with up to 256 channels. Each input can
have a range from 156 mV FS to 10V FS, which is programmable on a per-channel basis.
Multifunction I/O System
All of the aforementioned capabilities can be combined into one system, using one
DaqScan/2001 as the heart of the system. Such a DaqScan/2001 system could provide
56 non-isolated TC inputs, 16 isolated voltage inputs, 16 low-voltage inputs, 4 analog outputs,
4 frequency inputs, and 32 isolated discrete high-voltage outputs.
Reference Note:
