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.

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:
For information regarding DBK options refer to the DBK Options User’s Manual
(p/n 457-0905). A PDf version of the manual is included on your installation CD.

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

patch cable CA-242 (1.5 foot) or CA-242-7 (7 foot) cable is used to make the connection.

DaqLab/2000 Series & DaqScan/2000 Series 947091 Configuring the System for Operation 6-1

STEP 1 – Install the Software

1. Remove previous version Daq drivers, if present. You can do this through Microsoft’s
Add/Remove Programs feature.

2. Place the Data Acquisition CD into the CD-ROM drive. Wait for PC to auto-run the CD. This
may take a few moments, depending on your PC. If the CD does not auto-run, use the
Desktop’s Start/Run/Browse feature to locate and run Setup.exe [from the applicable
CD-ROM drive].

3. After the intro-screen appears, follow the screen prompts.

STEP 2 – Determine the type of Network Connection

To properly connect and configure the device you must determine the type of network it will
become part of. This is because the type of network used has a direct bearing on the IP
address of the device.

Briefly, the four network types are as follows:

Dedicated Network - with a direct cable connection from the PC to the

device

Dedicated Network - making use of a network hub or switch
LAN with a DHCP server

(Local Area Network with a Dynamic Host Configuration Protocol)

LAN without a DHCP server

(Local Area Network with no Dynamic Host Configuration Protocol)

Brief descriptions and illustrations follow.

Dedicated Network - with a direct cable connection from the PC to the device

In this scenario a DaqLab/2000 Series device is connected directly to an Ethernet
jack on a host computer. The following figure could just as easily portray a

6-2 Configuring the System for Operation 947091 DaqLab/2000 Series & DaqScan/2000 Series

Some network devices such as a wireless access point may act as a DHCP
server. If this is the case, follow the instructions for the LAN with a DHCP
server. For detailed information consult the documentation that is specific
to your network device.

Dedicated Network - making use of a network hub or switch

In the following figure a DaqLab/2000 Series device is connected to the Ethernet through a
network hub/switch. At least one computer is also connected to the hub. DaqScan/2000
series devices can be connected directly to the hub/switch in the same manner.

Dedicated Network using a Hub/Switch

LAN with a DHCP Server

(Local Area Network with a Dynamic Host Configuration Protocol server)

Many corporations use the LAN/Server with DHCP arrangement for their networks. In
this type of setup several computers are typically connected to a network that makes use
of a DHCP server. In addition, the primary data acquisition device, e.g., DaqLab/2001, is
connected to the network hub/switch.

Reference Note:

For information regarding connections, refer to Chapter 4, Connectors, Indicators, Cables,
& Pinouts.

Notes:

 Using a DaqLab/2000 Series or DaqScan/2000 Series device on a typical LAN may

affect the speed of the network and internet data transfer. Because of this we
recommend adding a network card to the computer and using one of the two
dedicated network configurations.

 Contact your network administrator before connecting your device to a corporate

network.

LAN with no DHCP Server

(Local Area Network with no Dynamic Host Configuration Protocol server)

This scenario looks the same as that shown in the previous illustration, except there is no
Dynamic Host Configuration Protocol (DHCP). In this type of setup, one or more computers
are connected to a network; and each computer has a static IP address.

STEP 3 – Connect the System Components

What you will need to connect your DaqLab/2000 Series or DaqScan/2000 Series

device to the Ethernet:

An available connection to the Ethernet. The connection can be either

- an Ethernet jack on a computer or

- an Ethernet jack on a hub that is connected to the Ethernet.

An Ethernet patch cable, e.g., a CA-242 (1.5 foot cable) or a

CA-242-7 (7-foot cable).

1. Connect the Ethernet cable to the Ethernet jack on the Daq device.

2. Connect the other end of the Ethernet cable to the Ethernet jack on the host
computer or network hub.

Safety Conditions ……7-2
Emissions/Immunity Conditions ……7-2
CE Enhancements for DBKs .…… 7-3
CE Compliance for System Expansion …… 7-3
Noise Considerations …… 7-4

CE-compliant products bear the “CE” mark and include a Declaration of Conformity
stating the particular specifications and conditions that apply. The test records and
supporting documentation that validate the compliance are kept on file at the
factory.

The European Union established CE standards in 1985. The standards include specifications
for safety, EMI emissions, and immunity from electromagnetic interference. Products that are
intended for placement in the European Union must meet or exceed the standards and bear
the "CE" mark.

Although not required in the USA, meeting or exceeding the CE standards is considered good
engineering practice, since doing so enhances safety while reducing noise and ESD problems.

In contracted and in-house testing, most Daq products met the required specifications. In
many cases, products that were not originally in compliance were redesigned accordingly. In
noted instances, alternate product versions, shield plates, edge guards, special connectors, or
add-on kits are required to meet CE compliance.

CE Standards and Directives

The electromagnetic compatibility (EMC) directives specify two basic requirements:

1. The device must not interfere with radio or telecommunications.

2. The device must be immune from electromagnetic interference from RF transmitters,

etc.

The standards are published in the Official Journal of European Union under direction of
CENELEC (European Committee for Electrotechnical Standardization). The specific standards
relevant to Daq equipment are listed on the product’s Declaration of Conformity.

The safety standard that applies to Daq products is EN 61010-1:1993 (Safety Requirements

for Electrical Equipment for Measurement, Control, and Laboratory Use, Part 1: General
Requirements). Environmental conditions include the following:

• indoor use

• altitude up to 2000 m

• temperature 5°C to 40°C (41°F to 104°F)

• maximum relative humidity 80% for temperatures up to 31°C (87.8°F) decreasing

linearly to 50% relative humidity at 40°C (104°F)

• mains supply voltage fluctuations not to exceed ±10% of the nominal voltage

• other supply voltage fluctuations as stated by the manufacturer

• transient overvoltage according to installation categories (overvoltage categories) I, II

and III. For mains supply, the minimum and normal category is II.

• pollution degree I or II in accordance with IEC 664

DaqLab/2000 Series and DaqScan/2000 Series 959195 CE-Compliance & Noise Considerations 7-1

For clarification, terms used in some Declarations of Conformity include:

• pollution degree: any addition of foreign matter, solid, liquid or gaseous (ionized

gases) that may produce a reduction of dielectric strength or surface resistivity.
Pollution Degree I has no influence on safety and implies: the equipment is at
operating temperature with non-condensing humidity conditions; no conductive particles
are permitted in the atmosphere; warm-up time is sufficient to avert any condensation
or frost; no hazardous voltages are applied until completion of the warm-up period.
Pollution Degree II implies the expectation of occasional condensation.

• overvoltage (installation) category: classification with limits for transient

overvoltage, dependent on the nominal line voltage to earth. Category I implies signals
without high transient values. Category II applies to typical mains power lines with
some transients.

Safety Conditions

Users must comply with all relevant safety conditions in the user’s manual and the
Declarations of Conformity. This manual and Daq hardware make use of the following
Warning and Caution symbols: If you see either of these symbols on a product, carefully read
the related information and be alert to the possibility of personal injury.

This warning symbol is used in this manual or on the equipment to warn
of possible injury or death from electrical shock under noted conditions.

This warning/caution symbol is used to warn of possible personal injury
or equipment damage under noted conditions.

Daq products contain no user-serviceable parts; refer all service to qualified
personnel. The specific safety conditions for CE compliance vary by product; but
general safety conditions include:

• The operator must observe all safety cautions and operating conditions specified in the

documentation for all hardware used.

• The host computer and all connected equipment must be CE compliant.

• All power must be off to the device and externally connected equipment before internal

access to the device is permitted.

• Isolation voltage ratings: do not exceed documented voltage limits for power and signal

inputs. All wire insulation and terminal blocks in the system must be rated for the
isolation voltage in use. Voltages above 30 Vrms or ±60 VDC must not be applied if any
condensation has formed on the device.

• Current and power use must not exceed specifications. Do not defeat fuses or other

over-current protection.

Emissions/Immunity Conditions

The specific immunity conditions for CE compliance vary by product; but general immunity
conditions include:

• Cables must be shielded, braid-type with metal-shelled connectors. Input terminal

connections are to be made with shielded wire. The shield should be connected to the
chassis ground with the hardware provided.

• The host computer must be properly grounded.

• In low-level analog applications, some inaccuracy is to be expected when I/O leads are

exposed to RF fields or transients over 3 or 10 V/m as noted on the Declaration of
Conformity.

7-2 CE-Compliance & Noise Considerations 959195 DaqLab/2000 Series and DaqScan/2000 Series

CE Enhancements for DBKs

The following CE enhancements are detailed in the DBK Cards and Modules User’s Manual
(p/n 457-0905).

• DBK41/CE

• Edge Guard (for DBK5, DBK8, and DBK44)

• Applicable cables and connectors

CE Compliance for System Expansion

The Daq devices are CE compliant at the time they leave the factory, and will remain in
compliance providing that the conditions stated on their respective Declaration of Conformity
cards continue to be met.

You may want to expand your data acquisition system while having it retain its “CE Compliant”
status. If so, refer to the most recent Declaration of Conformity for each device, prior to
making any efforts to expand the system.

Connecting a non-CE Compliant DBK module or card to your
system will make the system non-compliant.

In order to remain CE Compliant, DaqLab/2000 Series and DaqScan/2000 Series devices
require the use of ferrite inductive collars and a ground line, which are included in an Ethernet
CE Kit. Installation instructions for the kit follow this chapter.

General rules of thumb regarding expansion, while remaining CE Compliant, are:

•

Review the most recent Declaration of Conformity for each device.

•

Use short cables.

•

When possible, use shielded cables.

•

When assembling or disassembling components, take ESD precautions, including
the use of grounded wrist straps.

•

Ensure that the host computer is CE Compliant.

•

Ensure that expansion devices are CE Compliant

•

Ensure all system components are properly grounded.

DaqLab/2000 Series and DaqScan/2000 Series 959195 CE-Compliance & Noise Considerations 7-3

Noise Considerations

Controlling electrical noise is imperative because it can present problems even with the best
measurement equipment. Most laboratory and industrial environments suffer from multiple
sources of electrical noise. For example, AC power lines, heavy equipment (particularly if
turned on and off frequently), local radio stations, and electronic equipment can create noise
in a multitude of frequency ranges.

Local radio stations are a source of high frequency noise, while computers and other electronic
equipment can create noise in all frequency ranges. Creating a completely noise-free
environment for test and measurement is seldom practical. Fortunately, simple techniques
such as using shielded/twisted pair wires, filtering, and differential voltage measurement are
available for controlling the noise in our measurements. Some techniques prevent noise from
entering the system; other techniques remove noise from the signal.

While many techniques for controlling noise in signals provide a means of removing the noise
that is already present, the preferred solution is to prevent the occurrence of noise in the
signal in the first place.

The following practices, some of which are required for CE compliance, should be employed to
minimize noise.

• Make a solid earth ground connection. Required for CE Compliance
chassis of the primary data acquisition device, e.g., DaqLab/2001 is connected to earth
ground. This practice: (a) keeps radiated emissions low by keeping the chassis
electrically quiet, (b) keeps potential common-mode voltages low, (c) improves user
safety, and (d) provides a safe path for Electrostatic Discharge energy back to earth
ground. Use a shielded Ethernet cable, e.g., CA-242, to connect the DaqLab or DaqScan
chassis to the host computer’s chassis.

• Use short Ethernet cables. The use of short Ethernet cables will reduce noise. The
shorter the cable the better.

• Use shielded cables. Loose wires are effective antennae for radio frequency pickup and
can form loops for inductive pickup. The use of properly connected shields will greatly
reduce such noise.

• Minimize ambient EMI. The lower the ambient EMI, the better. Sources of
electromagnetic interference include solenoids, motors, computer equipment, high power
distribution wiring, etc.

• Distance cables. Power supply switch transients can vary in strength and frequency.
Ethernet cables can radiate digital switching noise. For these reasons route the power
supply and Ethernet cables such that they are as far as possible from all analog lines. The
analog lines include those that connect to P1 on the front panel, as well as those that
connect to the rear panel via an expansion port, or through the P4 connector.

• Use ferrite inductive collars. A clamp-on ferrite collar can be secured at each end of
the Ethernet cable and at both ends of the power supply cable. The collars on the
Ethernet cable will reduce digital switching noise. Note that the collars will not reduce the
integrity of the Ethernet channel if the system is making use of shielded Ethernet cables,
part number CA-242. Ferrite collars on the power cable will reduce the effects of power
transients.

Introduction

With signal lines connected and a system up and running you can begin acquiring data.
Specific connector details and pinouts are provided in chapter 4. You should refer to the
software documentation applicable to your data acquisition system, for example, DaqView.

Scanning

DaqScan/2000 Series devices have an on-board scan sequencer that permits the user to select
any combination of up to 16384 channel/range combinations. The sequencer scans all
channels contained in the sequence at the rate of 5 µs/channel, 10 µs/channel, or
1000 µs/channel, depending on the speed of the DBK expansion options; thereby minimizing
the time-skew from channel-to-channel. The user can also set the time between scan groups,
from 0 to 6 hours. In addition to scanning analog inputs, the sequencer can scan digital inputs
and counter inputs.

Digital and frequency inputs can be scanned using the same scan sequencer employed for
analog inputs, enabling the time correlation of acquired digital data to acquired analog data.

5µs, 10µs, or 1000µs
(See Note)

Note: All inputs can be measured at the 5 µs/channel rate. 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.

Triggering

Triggering can be the most critical aspect of acquiring data. DaqScan/2000 Series devices
support a full complement of trigger modes to accommodate a wide variety of applications.

Hardware Analog Triggering. Many data acquisition products claim analog triggering, but
rely on the PC to take readings and make a decision, which leads to uncertain and potentially
long latencies. DaqScan/2000 Series devices use true analog triggering, whereby the trigger
level programmed by the user, sets an analog DAC, which is then compared in hardware to
the analog input level on the selected channel. The result is analog trigger latency that is
guaranteed to be less than 5 µs, significantly shorter than most data acquisition devices. Any
analog channel can be selected as the trigger channel. The user can program both the trigger
level, as well as the edge (rising or falling).

Digital Triggering (P1).
digital trigger input line is provided, allowing TTL-level triggering, again with latencies
guaranteed to be less than 5 µs. Both the logic levels (1 or 0), as well as the edge (rising or
falling), can be programmed for the discrete digital trigger input. The digital trigger input is
labeled TTLTRG.

Digital Pattern Triggering (P2 and P3).
whereby the user can designate any of the digital input ports as the trigger port. The
programmed digital pattern, including the ability to mask or ignore specific bits, is then
compared to the actual input until a match is detected, after which the sequencer begins the
scan sequence.

Counter Triggering.
r
channels can be programmed as a trigger source.

Software-Based Triggering. Software-based triggering differs from the modes described
above because the readings [analo

that it permits triggering based on more complex situations. For example: to trigger on a
specific temperature, which was derived from the acquisition of at least two analog
measurements, plus the calculation of the measured temperature using linearization
algorithms.

Normally software-based triggering results in long latencies from the time that a trigger

circumvents this undesirable phenomenon by use of pre-trigger data. Specifically, when
software-based triggering is employed, and the PC detects that a trigger condition has
occurred, (which may be thousands of readings later than the actual occurrence of the signal),
the Daq driver automatically looks back to the location in memory where the actual trigger­causing measurement occurred. The acquired data that is presented to the user actually
begins at that point. The latency in this mode is equal to one scan cycle.

Pre- and Post-Triggering Modes. Six modes of pre- and post-triggering are supported,
providing a wide variety of options to accommodate any measurement requirement. When
using pre-trigger, the user must use software-based triggering to initiate an acquisition.

• No pre-trigger, post-trigger stop event. This, the simplest of modes, acquires

data upon receipt of the trigger, and stops acquiring upon receipt of the stop­trigger event.

• Fixed pre-trigger with post-trigger stop event. In this mode, the user

specifies the number of pre-trigger readings to be acquired, after which,
acquisition continues until a stop-trigger event occurs.

• No pre-trigger, infinite post-trigger. No pre-trigger data is acquired in this

mode. Instead, data is acquired beginning with the trigger event, and is
terminated when the operator issues a command to halt the acquisition.

• Fixed pre-trigger with infinite post-trigger. The user specifies the amount of

pre-trigger data to acquire, after which the system continues to acquire data until
the program issues a command to halt acquisition.

• Variable pre-trigger with post trigger stop event (driver support only). Unlike

the previous pre-trigger modes, this mode does not have to satisfy the pre-trigger
number of readings before recognizing the trigger event. Thus the number of pre­trigger readings acquired is variable and dependent on the time of the trigger
event relative to the start. In this mode, data continues to be acquired until the
stop trigger event is detected.

• Variable pre-trigger with infinite post trigger (driver support only). This is

similar to the mode just described, except that the acquisition is terminated upon
receipt of a command from the program.

• Stop Trigger. Any of the software trigger modes described above can be used to

stop an acquisition. Thus an acquisition can be programmed to begin on one
event, such as a temperature level, and then stopped on another, such as a digital
pattern event.

Synchronous I/O Operations

Synchronous Input Operations

The DaqScan/2000 Series devices allow synchronous scanning and acquisition of Analog Input
[for those models with a P1 connector], Digital Input and Counter Input Data at up to 200 kHz
aggregate scanning rates. When applicable, the Analog Input data can be either main unit
(DaqScan/2001 or DaqScan/2005) or expansion modules from P1-compatible analog input
modules. The Digital Input data can be main unit 8-bit P2 (8255) digital input or from P2
compatible DBK digital input expansion modules.

Analog Input Channels

P1 – Channels 0 through 15 (DaqScan/2001 and DaqScan/2005 only)

DaqScan/2001 and DaqScan/2005 allow analog input configuration of themselves, as well as
for any connected P1 compatible DBK analog input expansion modules.

Channel Selection and Mode Settings

DaqScan/2001 and DaqScan/2005 have P1 connectors that allow for expansion of up to 256
high-speed channels, or 896 TC channels. In regard to system expansion, refer to the DBK
Option Cards & Modules User’s Manual (p/n 457-0905).

Channel Range and Polarity

The analog input channels of DaqScan/2001 and DaqScan/2005 can be programmed for gain
settings of 1, 2, 4,

DaqScan/2000 Series 898195 Taking Measurements 8-3

8, 16, 32, and 64.

Channel Sampling Interval

In regard to analog input, DaqScan/2001 and DaqScan/2005 allow for programmable
sampling i

ntervals of 5 us, 10 us, or 1000 us on a per channel basis. This mode allows some
DBK expansion channels [that change slowly for a higher degree of accuracy] to be sampled at
a longer interval, and channels that change more rapidly to be sampled at a shorter interval.
Each 5 µs, 10 µs, or 1000 µs interval reduces the maximum aggregate acquisition rate for the
entire scan by that amount.

Digital I/O Channels

There are 40 Digital I/O channels available to DaqScan/2000 Series devices. The channels are
grouped as follows:

8 Channels, A0 through A7 from P2 Port A
8 Channels, B0 through B7 from P2 Port B

8 Channels, C0 through C7 from P2 Port C
16 Channels, Digital 0 through Digital 15 from P3

The devices allow for either synchronous scanning of digital input channels or asynchronous

Counter Input Channels

Counter 0, 1, 2, 3 (CTR0, CTR1, CTR2, CTR3)

DaqScan/2000 Series devices allow synchronous scanning of four16-bit counter input
channels. The 4 channels can be cascaded into two 32-bit counter channels. For either
cascaded or non-cascaded counter channels each channel can be configured for:

fie

• Pulse Counting Mode – speci

s that each counter should be cleared upon being

read and placed into the input scan.

• Totalize Counting Mode – specifies that each counter is to free-run and not be
cleared during the input acquisition.

Synchronous Input Acquisition Clocking

A /I Clock

DaqScan/2000 Series devices allow clocking of the synchronized inputs either by an internal,
programmable pacer clock or by external clocking. These products use a sequencer to
implement a multiplexing approach to gathering the input data. This means that with either
internal or external clocking the entire channel scan (including the samplin g time for each
channel) may not exceed the maximum aggregate rate of 200 kHz.

Synchronous Output Operations

DaqScan/2001 and DaqScan/2004 allow synchronous output of any available D/A channels
at up to 100 kHz for each channel. All D/A channels may have output clocked out
synchronously.

Asynchronous I/O Operations

Each DaqScan/2000 Series device allows asynchronous input of any counter or digital channel
that is not currently configured for synchronous acquisition. The circuitry allows for
asynchronous output to any D/A channels that are not currently configured for waveform
output. Likewise, the digital port can be used for both asynchronous input and output
operations. In addition, the timer outputs can be programmed at any time regardless of the
current state of synchronous or asynchronous operations on other channels.

Synchronizing Multiple Units

Up to four DaqScan/2000 Series devices can be synchronized to each other via their rear
panel SYNC connectors and associated cables. Each device has two identical SYNC ports;
either [or both] can be used to connect units. The DaqScan units can be scan-synchronized
and triggered from any other SYNC-connected unit. Note that cables CA-74-1 and CA-74-5
are 1-foot and 5-foot in length, respectively. The total combined cable length of the Sync
cables is not to exceed 15 feet (4.57 m).

Synchronization Concept Block Diagram

The preceding diagram shows how a DaqScan/2000 Series device can input or output
synchronization timing and trigger events on either SYNC connector. A more detailed block

Synchronization Model for DaqScan/2000 Series Devices (see note)

Note: DaqScan/2002 and DaqScan/2004 have no P1 connector; thus the pin 20

and pin 25 lines do not apply to those two devices.

8-6 Taking Measurements 898095 DaqScan/2000 Series

In regard to synchronization, the following applies:

• One of three signals can be used to drive the DaqScan/2000 Series acquisition scan

rate. These are:

− the internal acquisition pacer clock

− an external acquisition pacer clock (for DaqScan/2001 and /2005 only)

− the global sync (G-SYNC) input from the SYNC ports

• Both the SYNC connector input and the external clock input can be divided down.

• When a DaqScan is in the Master Mode, both the trigger condition and the scan timing

are output on the SYNC port. The global trigger (G-TRIG) is selected instead of the
TTL Trigger Input.

Whether the DaqScan is using its internal scan clock, or external clock input, it can be
programmed to output the clock on the SYNC connector. In either case, the unit is behaving
like a synchronization master. Other DaqScan units [that are connected to the master, via
a SYNC port] should be programmed as synchronization slaves.

When a DaqScan is programmed as a synchronization slave, it will derive its scan period from
the SYNC port. If the slave unit must be triggered at the same time as the master unit, then
the slave unit should use TTL Trigger as its trigger source.

Sync Notes:

• When a DaqScan/2000 Series device is programmed as a synchronization slave, the TTL

trigger source is automatically derived from the SYNC port.

• When a DaqScan/2000 Series device is programmed as a synchronization master, it will

output its trigger condition on the SYNC port.

• When synchronizing two or more DaqScan/2000 Series devices, the slave units should have

at least 0.1 µs of dead time in the scan period. By “dead time,” we mean a duration in
which no channels are sampled. This accommodates fundamental differences in the clocks
[for each DaqScan].

• All DaqScans that are connected via SYNC cables can be scan-synchronized to within

0.1 µs of each other.

• A maximum of 4 units can be synchronized; scan-synchronous (post-trigger).

• Sync cables are not to exceed a total combined length of 15 feet (4.57m).

Multi-unit synchronization via the SYNC ports does not support pre-trigger
data. Only post-trigger data can be collected and time correlated between
the units.

Using DBK Cards and Modules for Signal Conditioning

The DBK signal-conditioning cards and module are designed for use with DaqLabs, DaqScans,
DaqBooks, LogBooks, and various types of 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.

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, the manual is automatically loaded
onto your hard drive during software installation. The default location is the

Calibration 9

Overview …… 9-1
Using DaqCal.exe …… 9-1

Overview

Daqscan/2000 Series devices are digitally calibrated at the factory. The di gital method
involves storing a correction factor on the circuit board for each range at the time of
calibration. Whenever a particular range is selected, the appropriate calibration constant is
automatically applied to a compensating DAC, thereby calibrating the specific range. The
result is that readings generated by the A/D are already calibrated, and do not require
additional processing.

This is significantly better than the calibration method in which readings are adjusted in
software after they are transferred to the host
the A/D

Electrostatic Discharge (ESD), Handling Notice

The discharge of static electricity can damage some electronic components. Semiconductor
devices are especially susceptible to ESD damage. You should always handle components
carefully, and you should never touch connector pins or circuit components unless you are
following ESD guidelines in an appropriate ESD-controlled area. Such guidelines include the
use of properly grounded mats and wrist straps, ESD bags and cartons, and related
procedures.

Product Care

Daq products and DBK options are essentially maintenance free and require a minimal amount
of care. They should be treated much like any other high-tech equipment. In general:

• Keep them clear of harsh chemicals and abrasive elements.

• Avoid exposing the products to extreme heat, for example, avoid setting up a Daq system

near a boiler or furnace.

• Avoid extreme shock and vibration.

• Avoid subjecting the units to liquids and extremely fine air particulate, such as silica dust.

• Never touch circuit boards without proper ESD (Electrostatic Discharge) measures in

place.

A “common-sense” approach to handling your data acquisition equipment will go a long way in
protecting it from inadvertent damage.

Note that you can use lint-free rags and Isopropyl Alcohol
(Rubbing Alcohol) to clean the outer plate surfaces of Daq
devices and optional DBK modules.
