This chapter provides a brief overview of Daq devices.

Users interested in jumping straight to DaqScan information
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.

LabView can be used with multiple Daq/2000 Series devices.

Using DBK Cards and Modules for Signal Conditioning

The DBK signal-conditioning cards and modules are designed for use with DaqLab, DaqS can,
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

System Applications

In addition to basic applications that make use of a DaqScan model’s built-in I/O, a wide
variety of signal conditioning and expansion options make additional appl ications 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:

or digital I/O expansion port controlling up to 272 external lines. Programmable as input or

output. P2 can be used to connect to an optional digital DBK card.

P3 - DB37 Connector: 16-bit digital I/O port with 4 counter inputs and 2 timer outputs. In

addition, DaqScan/2001 and DaqScan/2004 each have a P3 connection to 4 analog outputs

(DAC0, DA1, DAC2, and DAC3).

POWER Switch and Power LED: A rocker-type switch with a “0” label for Power Off, and a
“1” for Power On. When the unit is on and has power, the POWER LED will light. An AC to DC
power converter resides within each DaqScan/2000 series device.

MAC Address Label: The Media Access Control (MAC) label shows the device serial number in

three formats: (1) Barcode, (2) base 10, and (3) hexadecimal. If prompted to enter a serial

number in software, use the base 10 number. Conversion to a hexadecimal number for use in

addressing will be automatic.

ETHERNET: The 10/100BaseT Ethernet jack can be used to connect to the Ethernet port of

the host PC, or to an Ethernet network. Either of two Ethernet patch cables may be used to

make the connection. CA-242 is a 1.5 foot cable. CA-242-7 is a 7-foot cable.

The Ethernet connector has two built in LEDs (Tx and Rx) that indicate traffic flow. These are

defined in the following LED section. Note that the Ethernet cable length must be <10m in

order for the system to be CE Compliant.

LEDs: There are 5 ETHERNET Status LEDS. Two rectangular LEDs, Tx

and Rx are built right into the frame of the Ethernet jack. The other

three, located just to the right of the jack, are round and are labeled L, T,

and D.

Tx – “ON” indicates traffic is being transmitted (see figure at
right).

Rx – “ON” indicates that the port is receiving traffic.
L (Link) “ON” indicates a link exists. “OFF” indicates no link.
T (Transmit) “ON” indicates 100 M-Bits, “OFF” indicates

10 M-Bits.
D (Duplex) “ON” indicates full duplex, which allows

simultaneous two-way data traffic. “OFF” indicates half­duplex, which only allows one-way data traffic at any
given time.

Tx and Rx LEDs

SYNC (Qty of 2) – Two “synchronization ports” provide a means of synchronizing up to four

DaqScan/2000 Series units in regard to post post-trigger scanning. The ports accept CA-74-1

and CA-74-5 RJ-11, 6 conductor type cables. The total combined length of the SYNC cables is

not to exceed 15 feet (4.57 m).

POWER IN: 90 to 250 VAC, 3-prong socket for power cord.
