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.

Overview 1-1

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-to­channel 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.

1-2 Overview

02-13-02

OMB-Daq Systems

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.

Daq Software

The Daq devices have software options capable of handling most applications. Three types of software are
available:

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.

•

ready-to-use graphical programs, e.g., DaqView, DaqViewXL, and post acquisition data analysis
programs such as PostView, DIAdem, and eZ-View

•

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-View, 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.

(a) Run the Daq Configuration control panel applet.

(b) Click “Add Device.”

(c) Select your DaqBoard model from the “Device Type” scroll box

and click OK.

(d) Select your DaqBoard from the “Device Inventory” window and

click “Properties.”

(e) Ensure settings are correct, and make changes if needed.

(f) Select the “Test Hardware” tab.

(g) Click the “Resource Test” button.

(h) Click the “Test” button.

Test results should be displayed within a few seconds. Note that test
results have two components: Resource Tests and Performance

Tests.

Note: Testing the DaqBoard device may, in some cases, cause the

system to hang. If test results are not displayed in 30 seconds
or the system does not seem to be responding, reboot the
system. Upon power-up, re-enter the Daq Configuration and
change DaqBoard configuration settings to those that work
properly.

Resource Tests

The 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 availability of the resource
or a possible resource conflict.

•

Base Address Test - Tests the base address for the selected

ISA bus. Failure of this test may indicate that the bus 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 ISA bus to

generate interrupts. Failure of this test may indicate that the
ISA bus may be currently unable to generate the necessary
hardware interrupt.

Performance Tests

Performance tests check various DaqBoard 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. Note that the rates
depend on selected ISA protocol and will vary according to bus
hardware capabilities.

•

ADC FIFO Input Speed - Tests the maximum rate at which

data can be transferred from the DaqBoard’s internal ADC
FIFO to computer memory, through the PC’s ISA bus.
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 DaqBoard’s Digital
I/O ports to computer memory, through the PC’s ISA bus
slot. Results are given in bytes/second.

•

Digital I/O Output Speed – Tests the maximum rate at which

DIO output data can be transferred from the computer’s
memory to DaqBoard’s Digital I/O ports, through the PC’s
ISA bus slot. Results are given in bytes/second.

The DaqBoard/100A, /112A, /200A, and /216A are 100 kHz ISA-bus plug-in boards that provide analog­to-digital conversion with a wide selection of signal-conditioning, signal expansion, and software support.
ISA-DaqBoards feature an on-board 512-location sequencer that lets you select any channel and gain
combination and configure each channel for unipolar or bipolar operation.

Analog input capabilities are flexible. 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 P1 I/O connector. Refer to the Connections section beginning on
page 3-5. The P1 DB37 interface is compatible with multiplexers and signal conditioners from several
manufacturers.

Input power for the DaqBoard comes from the host computer’s bus. Output power from the P1 connector
includes +5 VDC (pin 1) and ±15 VDC (pins 21 and 2). The section beginning on page 3-4 entitled,

External Analog Expansion Power (JP1), explains how to set JP1 based on power use in the system.

Related information is included in the Power Management section of the DBK Option Cards and Modules
User’s Manual (p/n OMB-457-0905).

Each ISA-DaqBoard provides 16 analog inputs (expandable up to 256), 2 analog outputs, and 4 digital
inputs and outputs. DaqBoard/100A and DaqBoard/200A have additional digital I/O and counter/timer
capabilities. The various DaqBoard models have either 12-bit or 16-bit resolution. 12-bit models include
DaqBoard/100A and DaqBoard/112A. 16-bit models include DaqBoard/200A and DaqBoard/216A.

Performance Factors

The DaqBoard performs 100 kHz scan sequences and provides programmable delays from 10 µs to
12 hours. The unit’s 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. The
DaqBoard/100A and DaqBoard/200A can 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
ISA-DaqBoards to sample up to 256 channels at the same instant. Scanning and timing specifications are
met even with a full complement of expansion modules. All types of transducers are scanned within the
same scan group without PC intervention.

ISA-type DaqBoards offer a wide selection of triggering capabilities. The scan can be triggered by
software, a TTL signal, or an analog input level (including slope). The trigger is hardware-based to
minimize trigger latency to less than 10 µs.

Two data transfer modes are supported:

Real-time data can be collected at 100 K readings/s.

Switches and Jumpers

y

To ensure that the desired mode of operation is obtained, the ISA-type DaqBoards must be configured.
This is accomplished via on-board jumpers and a DIP-switch. Although the configuration of all four
DaqBoard-ISA models is similar, jumper locations differ, as can be seen in the following figures.

DaqBoard/100A/112A Motherboard

The following DIP-switch and jumpers must be properly set to ensure the desired mode of operation:

•

•

•

•

•

Base Address (SW1)

The computer must know the DaqBoard’s base address. Check the base address setting (3-digit hex) on
SW1, the Base Address switch. The factory default is 300 hex (within the standard range for a prototype
card; see table). If the default value does not work, you must select an address within 200 to 3FF (256 to
1023 decimal). In addition, the address must be on a 4-byte boundary, and it must not conflict with
addresses already in use.

External Analog Expansion Power (JP1)

Def

The JP1 4×2 header has 3 possible settings.
If analog option cards (DBKs) are used, the
JP1 pins are set to provide ±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.

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.

Reference Note:

Refer to the Power Management section of the DBK Option Cards and Modules User’s
Manual (p/n OMB- 457-0905), as needed.

DAC Reference Selection (JP2)

The JP2 5×2 header allows you to select internal or external voltage references for the two separate analog
outputs. If the internal -5 VDC reference is selected, either DAC can output from 0 to +5 VDC as the
register count varies from 0 to 4095 (12-bit). If an external voltage reference is desired (up to 10 VDC in
either polarity), the shunt jumpers must be set accordingly. There is also a provision to allow the outputting
of a simultaneous Sample-Hold command signal on the DAC1-REFIN pin with the DAC1 set up for an
internal reference.

OMB-DaqBoard-ISA User’s Manual

DMA and Interrupt Selection (JP8)

The JP8 11×2 header determines both the interrupt IRQ level and the Direct Memory Access (DMA)
channel for control of background data transfers. The preset default is for DMA channel 5 and for
Interrupt 10 (see figure).

•

Interrupt Selection. The DaqBoard may be set to interrupt the PC when certain hardware conditions
occur. The main board interrupt may be set to IRQ level 10, 11, 12, 14 or 15. The DaqBoard’s IRQ
level cannot be shared with any other device. Setting the JP8 interrupt jumper to OPEN can disable
interrupt assistance and background transfers.

•

DMA Selection. Direct Memory Access allows high-speed data transfer either from the ADC FIFO
or to the DAC FIFO. Only DMA channels 5, 6, and 7 (of an ISA AT machine’s seven channels) are
available for the DaqBoard. Set both the DRQ and DACK jumpers to the desired DMA channel (the
DaqBoard does not share DMA channels). Set the DMA jumpers to OPEN when other devices use
DMA channels 5, 6 and 7.

Connections

Expansion cards connect to the ISA-type DaqBoards via one externally accessible P1 DB37 I/O connector,
or by two on-board 40-pin headers [for P2 and P3 connections] on the DaqBoard/100A and the
DaqBoard/200A. The DBK option cards can be used without an enclosure, or can be installed in a multi­card enclosure such as the DBK10, DBK41, or DBK60. The multi-card enclosures can be stacked, making
it possible for a system to accommodate a large number of cards.

DaqBoard [ISA type] Multi-Card Cabling

OMB-DaqBoard-ISA User’s Manual

02-14-02

Hardware 3-5

The P1 connector on the DaqBoard and on each DBK is a DB37 male connector. Connecting DBKs to a
DaqBoard is accomplished with a CA-131-x cable, where the x is the number of option cards to be
connected; for example, a CA-131-3 cable would be used to attach three DBK option cards to a DaqBoard.
Such connections are often referred to as a “daisy-chain.” Note that the CA-131-x cables consist of female
DB37 connectors.

&$87,21

Before connecting DBKs to the DaqBoard, power-down all connected units.
Failure to do so could result in damage to the DBK or DaqBoard.

&$87,21

Do not confuse connectors. Ensure that you only connect P1 I/Os to P1,
P2 I/Os to P2, and P3 I/Os to P3. Improper connection may result in equipment
damage.

In addition to P1 ports, DaqBoard/100A and DaqBoard/200A devices have P2 and P3 ports. For these
devices a CA-60 cable is required to connect the DaqBoard 40-pin headers with a DB37 connector outside
the PC, and then to the DBK option card.

A DaqBoard with CA-60 Cables for P2 and P3

•

P1 Analog I/O. Provides sixteen analog input channels, two analog output channels, a 16-bit
counter/timer, four TTL inputs and outputs, and various signals for driving expansion cards.

•

P2 Digital I/O. Provides three 8-bit TTL programmable I/O ports and external interrupt
input.

P2 expansion cables must be kept relatively short to ensure reliable operation. Do not
exceed 14 inches per attached DBK card.

•

P3 Frequency I/O. Provides five16-bit counters and sixteen high-speed digital inputs and
external interrupt input.

To gain access to the DaqBoard port connectors, signals can be connected via CA-131-x cable through a
D-shell 37-pin female connector or a DBK11 screw-terminal option card with component sockets.

Reference Notes: You must set up DaqView for the particular DBKs in your system. If you
are unfamiliar with the method of setting up DBKs in DaqView, or if you need a refresher,
refer to one or more of the following:

➣

Notes

:
(1) Software configuration commands determine P1 digital I/O pin functions.
(2) Actual shunt-jumper placement is required to provide ±15 VDC to expansion cards or disconnect internal DAC references to

allow externally selected DAC references.

(3) Digital I/O is not available with DBKs due to line use for addressing. “/” indicates the pin can be used for either function but not

both at the same time.
(4) DaqBoard [ISA-Type] P1 is compatible with Metrabyte DAS-16.
(5) The pinout is for ISA-type DaqBoards. It does not apply to PCI or cPCI type DaqBoards.

Introduction

The term “DBK” typically refers to a card or module that is used to expand or enhance a primary data
acquisition device, such as a DaqBook, DaqBoard, or LogBook. As will be seen in the upcoming DBK
identification tables, DBKs provide a wide variety of data acquisition functions. Depending on the DBKs
used, one or more of the following can be realized:

Turn off power to all devices connected to the system before connecting cables or
setting configuration jumpers and switches. Electrical shock or damage to
equipment can result even under low-voltage conditions.

&$87,21

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.

the PDF documentation, especially the DBK Option Cards and Modules User’s Manual
(p/n OMB-457-0905) for details regarding both hardware and software in relevant to DBKs.

A copy of the Adobe Acrobat Reader

is included on your CD. The Acrobat Reader
provides a means of reading and printing the PDF documents. Note that hardcopy versions
of the manuals can be ordered from the factory.

How Do DBKs Connect to the Data Acquisition Device?

Each DBK connects to the primary data acquisition device; e.g., a DaqBook, DaqBoard, or LogBook,
through one of three 37-pin ports, which are designated as follows:

•

P1 – Analog I/O

•

P2 – Digital I/O

•

P3 – Pulse/Frequency/High-Speed Digital I/O

Depending on the primary data acquisition device, connectivity issues differ slightly. This will be made
clear by the figures and accompanying text that follow.

For DaqBooks, ISA-Type DaqBoards, and LogBooks, DBK connections are not made directly to the port,
but through a CA-37-x ribbon cable, where “x” indicates the number of expansion devices that can be
connected. For example, in addition to providing a DB37 connector to interface with the primary data
acquisition device, a CA-37-3 cable includes three additional DB37 connectors. These provide a means of
adding three DBKs to one port. Use of a CA-37-16 cable will allow up to 16 DBKs to be added. The
CA-37-x cable system is excellent for DaqBooks, LogBooks, and ISA-type DaqBoards.

The above figure applies to LogBooks, DaqBooks, and ISA-type DaqBoards. As will be seen elsewhere in
the documentation, some models do not include all three connectors (P1, P2, and P3).

Analog Signal Conditioning DBKs

The DBKs that are used for analog signal conditioning attach to transducers and condition their outputs into
analog voltages. An A/D converter, located in the primary acquisition device, measures the analog
voltages. There are many signal-conditioning solutions available (and more are in development). Note that
DBK high-capacity modules require more circuitry than can fit on a compact card.

Power Supply DBKs

Power supply type DBKs are typically used in laboratory, automotive, and field applications. Input power
can come from any +10 to +20 VDC source, or from an AC source by using an appropriately rated AC-to­DC adapter. The DBK30A rechargeable power supply can power DBK modules where AC mains are not
available (the DBK30A outputs 28 V for powering transducers). For a large number of DBK cards, the
DBK32A or DBK33 can be installed into an expansion slot. The DBK33 is used when +5 V is required in
addition to ±15 VDC. The DBK34 provides a steady 12 or 24 VDC while working with vehicle electrical
systems that may be turned on or off during testing.

Tips on Setting up a Data Acquisition System

A successful installation involves setting up equipment and setting software parameters. In addition to this
manual, you may need to consult your Daq device or LogBook user’s manual.

DBKs should be configured before connections are made and power is applied. This sequence can prevent
equipment damage and will help ensure proper operation on startup. Many DBKs have on-board jumpers
and/or DIP switches that are used for setting channels and other variables. You will need to refer to the
individual DBK document modules to ensure that the DBKs are properly configured for you application.

Prior to designing or setting up a custom data acquisition system, you should review the following tips.
After reviewing the material you can write out the steps to setup a system that will best meet your specific
application needs.

pg. 4, OMB-DBK Basics

02-19-02

Daq Systems

1. The end use of the acquisition data should be used to determine how you set up and program your
acquisition system. Prior to creating the system you should understand its layout and know how you
are going to assign the channels. If you can answer the following questions you are off to a good start.
If not, you need to find the answers.

•

What engineering units, ranges, sampling rates, etc. are best for your data?

•

Will the data be charted graphically, statistically processed, or exported to other programs?

•

How will the data be used?

•

How will the data be saved?

•

What are your system’ power requirements? Using several DBKs or transducers that
require excitation current may require an extra power supply, e.g., a DBK32A.

2. Assign channel numbers.

3. Plan the location of transducers, cable runs, DBKs, the acquisition device [LogBook or Daq device],
and the computer. Label your transducers, cables, and connectors to prevent later confusion.

4. When configuring your LogBook or Daq device(s) consider the following:

•

LogBook calibration is typically performed automatically through LogView software;
however, some DBKs may require manual calibration.

•

The DaqBook and DaqBoard (ISA type) have internal jumpers and switches that you
must set manually to match your application.

•

Some DaqBook models are partially configured in software.

•

Daq PC-Cards are configured entirely in software.

•

You may need to refer to other documentation, such as Quick Starts, Installation Guides,
User’s Manuals, and pertinent DBK document modules.

5. Perform all hardware configurations before connecting signal and power. Remember to configure all
the DBK cards and modules for your application. Several jumpers and DIP switches may need to be
set (channel, gain, filters, signal mode, etc).

6. Setting up channel parameters often requires both hardware and software setup.

7. Route and connect all signal and power cables while all power is turned OFF.

8. To minimize electrical noise, route all signal lines away from any RF or high-voltage devices.

9. Follow your device’s specific installation instructions. For certain devices software should be installed
first; for others, hardware should be installed prior to software installation.

10. After software is loaded, remember to set the software parameters as needed for your

application. The software must recognize all the hardware in the system. Measurement units
and ranges should be checked to verify that they meet your application requirements.

11. Remember to set all channels to the proper mode for your DBK or other signal source.

12. After your system is up and running, verify proper data acquisition and data storage.

13. Verify system accuracy; adjust ranges or calibrate as needed.

14. Device specific information regarding system setup and expansion can be found in the Daq and
LogBook User’s manuals; and in the applicable DBK document modules of this manual.

modules. The best option depends on the number of DBK cards in your system. For just a few cards,
use the stackable 3-slot DBK10 low-profile expansion enclosure. For more than six cards, use the
10-slot DBK41. DBK41s can be daisy-chained to one-another to handle a large number of DBKs.

In regard to power management, you should review the DBK30A, DBK32A, and DBK33 document

modules. For portable applications, the compact DBK30A rechargeable power supply can provide
power to the DBK10 or DBK41. The DBK30A also includes a 28 V output for powering 4 to 20 mA
transducers. For applications with many DBK cards (initially or in future expansion), the DBK32A or
DBK33 can be installed into any expansion slot. The DBK32A provides ±15 VDC and the DBK33
provides ±15 VDC and +5 VDC.

Power Supplies and Connectors

Power supplies convert the raw power they receive into a lower DC voltage and/or current for use by
devices with various power demands. Many of the power supplies that are used to power data acquisition
equipment are of the switching-mode type. These devices provide a regulated output whether the power
supply’s input is, for example, 60 Hz, 120 VAC as in the United States or, 50 Hz, 220 VAC as found in
European countries. Small power supplies, that do not switch, consist of simple transformer/rectifiers and
filtered capacitors; and operate over a smaller voltage range.

LogBooks - The switching-mode power supply commonly used with LogBook systems uses an input
range of 100 VAC to 240 VAC at 50 Hz to 60 Hz. The power supply’s output [to the LogBook] is
15 VDC @ 2.7 amps via a DIN5 connector.

DaqBooks - Power supplies that are used with DaqBooks are typically of the transformer/rectifier type.
They supply the DaqBook with 15 VDC @ 900 mA via a DIN5 connector.

DBKs – The following table indicates the type of power supply that is typically used with certain DBKs.

15 VDC @ 2700 mA

Switching-Mode

An Introduction to Power-Related DBKs

The power-related DBK options are the DBK30A, DBK32A, DBK33, DBK34, and DBK34A. From the
standpoint of providing reliable power, these DBKs have proven convenient in laboratory, automotive, and
field applications.

Input power for these devices can come from any 10 to 20 VDC source, or from an AC source via an
appropriate AC-to-DC adapter.

A brief synopsis of the DBK power options follows. Refer to the respective document modules for
complete information.

DBK30A

The DBK30A’s 28 V output will power 4 to 20 mA transducers.

module - provides power at 14 and 28 VDC with a rated capacity of 3.4 A-hr @ 14 VDC.

The module’s rechargeable power supply can power

DBK modules in situations where AC mains are not available.

Note: Some transducers (e.g., 2-wire 4-20 mA transmitters, bridge-configured sensors, etc) require an

excitation voltage in order to work properly. The DBK30A supplies 14 and 28 VDC. Consult
transducer documentation before applying power.

Daq Systems

02-19-02

OMB-DBK Basics, pg. 7

DBK32A

- provides ±15 VDC @ 500 mA.

DBK33

- provides ±15 VDC @ 250 mA and +5 VDC @ 1000 mA.

The DBK32A and DBK33 power cards attach directly to the P1 analog expansion bus where they supply power
to DBK analog expansion cards. The DBK32A and the DBK33 can be powered from an included AC adapter,
an optional DBK30A battery module, or from a +10 to +20 VDC source such as a car battery.

When installed in a DBK10

three-slot expansion chassis, the DBK32A or DBK33 supplies power to

the analog DBK [that is to receive power] via a CA-37-x cable.

If used with the DBK41

ten-slot expansion enclosure, the DBK32A or DBK33 installs into one of the analog
expansion slots on the DBK41’s backplane. A power card in any DBK41slot (other than the leftmost, when
viewed from the rear) will power the other cards that are connected to the DBK41’s backplane.

&$87,21

If using a DBK32A or a DBK33 with a DaqBook or DaqBoard [ISA type], you must
entirely remove the shunt jumpers from JP1. Failure to do so will result in damage to the
8254 timer chip. Refer to the power card document modules and to the Daq device
Hardware sections of the DaqBook and DaqBoard [ISA] user’s manuals for JP1 location
and configuration.

DBK34

Uninterruptable Power Supply (UPS) that can be used for in-vehicle testing where the vehicle’s electrical
system will not affect acquisition device power during starter-current surge, or power-off.

module – provides 12 or 24 VDC with a 5.0 or 2.5 A-hr capacity (respectively). This module is an

DBK34A

classified as a UPS / Battery module. It is an improved version of the earlier DBK34. Like the DBK34, the

Use the following procedure and table to calculate the required system power.

1. In the Quantity column (5th), list the number of DBKs of that type in your system.

2. In the Sub Total column (7th), enter the product of column 5 and column 6 (mW).

3. Add the Sub Total column, and enter the sum at the bottom right of the table.
This result is your power requirement in mW.

DBK32, DBK32A, and DBK34 cannot supply +5 VDC.
In cases that require +5 VDC, if the +5 VDC requirement exceeds 500 mW from a
LogBook or Daq device, then a DBK33 must be used. Note that DBK33 can supply
1000 mW at +5 VDC.

Note:

The DBK34 has an 8 amp fuse, and has a capacity of 5 A-hr when in the 12V mode,
and a capacity of 2.5 A-hr when in the 24V mode.
