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.

OMB-Daq Systems 10-29-02 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-to-

channel 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

10-29-02 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-PostView

• 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-PostView, 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.

DaqBook/100, /112, /120, /200, and /216

In General

DaqBooks consist of boards enclosed in a 8.5 × 11 × 1.375 inch metal chassis; with exception of the DaqBook/260, which is 11 × 13 × 3.5 inches. DaqBooks attach to a host PC’s parallel port via a 25-wire parallel port cable and can transfer data bi-directionally at up to 170 Kbytes/s for a standard printer port (SPP) and up to 800 Kbytes/s for an enhanced parallel port (EPP). Data is stored in the PC’s memory and hard drive, not in the DaqBook.

DaqBooks can be powered from a suitable AC-to-DC power adapter, a 12 V car battery, or a rechargeable NICAD battery module. This power flexibility is ideal for portable and remote data acquisition, such as automotive and aviation in-vehicle testing.

Output power from the DaqBook’s P1 connector includes: +5 VDC via pin 1, +15 VDC via pin 21, and

-15 VDC via pin 2.

DaqBooks have capabilities which, at one time, could only be met by using several plug-in DAS boards. All DaqBooks provide 16 analog inputs, and can be expanded up to 256. In addition, each model has 2 analog outputs, and at least 4 digital I/O channels. Some models have built-in expansion slots; other models have additional digital I/O and counter/timer capabilities.

DaqBook Differences

While all DaqBook models are closely related, the following should be noted.

Performance Factors

DaqBooks are flexible when it comes to analog input capabilities. The A/D maximum sample rate is 100 kHz (divide by number of channels for scan rate) with a 16-channel multiplexer and a programmablegain 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 DaqBook’s 37-pin P1 I/O connector.

The DaqBooks can perform 100 kHz scan sequences with programmable delays from 10 µs to 10 hours. The 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. DaqBook models /100, /120, /200, and /260 can each 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 DaqBooks to instantaneously sample up to 256 channels. Scanning and timing specifications are met, even when a DaqBook system includes a full complement of expansion modules. All types of transducers are scanned within the same scan group, and with no intervention from the host PC.

DaqBooks offer a wide selection of triggering capabilities. Scans can be triggered by software, a TTL signal, or a level of analog input [including slope]. The analog input trigger is hardware-based and minimizes trigger latency to less than 10 µs.

Jumpers

Proper installation requires that several jumpers and switches be set correctly for your application. These jumpers and switches are located inside the DaqBook enclosure and possibly on your DBKs. Jumpers for the various DaqBook models are configured similarly except for the jumpers’ relative locations. Silkscreening on the motherboard identifies jumpers and switches. Note: Even if using the default settings, you should verify actual jumper positions.

The DaqBook configuration jumpers include:

• JP1 - External Analog Expansion Power; default is Analog Option Card Use

• JP2 - DAC Voltage Reference; default is DAC0 and DAC1 internal reference with SSH

• JP3 - Unipolar/Bipolar; default is bipolar (Note 1)

• JP4 - Differential/Single Ended; default is single ended (Note 1)

• JP5 - Time Base; default is 1 MHz

• JP6 - Watchdog Timer; default is Watch Dog timer disabled

• JP7 - Reserved for factory use.

Note 1: DaqBook/200, DaqBook /216, and DaqBook /260 do not have JP3 and JP4 jumpers.

For these products the related settings are made via software.

Location of DaqBook Jumpers

External Analog Expansion Power (JP1)

This 4×2 header (JP1) has 3 possible settings. If analog option cards (DBKs) are used, the JP1 pins are set to provide +15 and -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.

CAUTION

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.

DAC Reference Selection (JP2)

This 5×2 header (JP2) 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 or –10 VDC), 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.

Note: The SSH setting is used with DBK2, DBK4, DBK5, DBK7, DBK17, DBK50, and DBK51.

Bipolar or Unipolar A/D Operation (JP3)*

*Hardware Setting For DaqBook/100, DaqBook /112, and DaqBook /120 Only

The A/D converter in the DaqBook can be operated in two modes, bipolar or unipolar. In the bipolar mode (default setting), input voltages up to ±5 VDC can be applied (on the ×1 gain range). In the unipolar mode, positive voltages up to 10 VDC may be applied (×1 gain range). Refer to the table below for gain, range, and mode relations.

JP3 is a double-wide jumper that must be positioned vertically. Misplacing this jumper in a horizontal position will damage the unit.

Gain Mode Volts Range

×1 BI ±5 ×2 BI ±2.5 ×4 BI ±1.25

×8 BI ±0.625 ×1 UNI 0 to +10 ×2 UNI 0 to +5

×4 UNI 0 to +2.5

×8 UNI 0 to +1.25

JP3 Unipolar/Bipolar Operation Settings

Note: For the DaqBook/100, /112, and /120, set the jumpers to the desired position as shown in figure.

Note: For the DaqBook/200, /216, and /260 the Unipolar/Bipolar option is selected via software by the

daq200SetMode and daq200SetScan commands.

Single-ended or Differential Analog Input Channels (JP4)*

*Hardware Setting For DaqBook/100, /112, and /120 Only

CAUTION

JP4 must be positioned vertically. Positioning JP4 horizontally will damage the unit.

JP4 is a 3×2 header used to configure the 16 analog input lines as 16 single-ended channels or as 8 pairs of differential channels. In general, if the DaqBook is going to be used in the stand-alone mode (no analog expansion cards), either mode can be used. If analog expansion cards (each DBK capable of sixteen single-ended or differential inputs) are used, the single-ended mode must be used. The default setting is thus single-ended. Place the jumpers in the desired position (see previous figure).

Note: For the DaqBook/200, /216, and /260, the Unipolar/Bipolar option is selected via software by the

JP4 Single-Ended/Differential Settings

daq200SetMode and daq200SetScan commands.

3-6 DaqBook Hardware 01-23-02 OMB-DaqBook User’s Manual

Time Base Selection (JP5)

JP5 is a 2×3 header that allows you to apply 1 of 3 oscillatorderived frequencies to the 8254 timer chip. The frequencies are 100 kHz, 1 MHz, and 10 MHz. The default setting is 1 MHz.

Note: A special-version 8254 timer-chip is required for 10 MHz.

DaqView and most 3rd party software assume the 1 MHz time base.

JP5 Time Base Settings

Watchdog Timer Enable/Disable (JP6)

This 3-pin header (JP6) allows the elective use of the watchdog timer. The watchdog timer is used to assure consistent operation of the pass-through printer port during data collection and to restore pass-through printing if the computer is reset. Enable the watchdog timer if you:

• Use a printer on the pass-through printer port

• Expect the computer to be suddenly reset during DaqBook operation

• Want the DaqBook to reset itself rather than having to manually toggle the

DaqBook’s power switch. Place the shunt jumper in the desired position as shown in the figure. The default setting is Disabled.

JP6 Watchdog Timer

Settings

Connections

Note: The watchdog timer can mistake a computer pause for a reset and then impede background

measurements. For this reason, the watchdog timer should normally be disabled unless automatic restoration of pass-through printing is required.

The DaqBook connects to the computer’s DB25F parallel printer port with a DB25M to DB25F 1284 Compliant LPT cable. 2-foot and 6-foot length cables of this type can be ordered through the factory. The part numbers are CA-35-2 and CA-35-6, respectively.

Connect the male end to the computer and the female end to the DaqBook connector labeled FROM PC PARALLEL PORT. Any printer port (LPT1, LPT2, or LPT3) may be used but should be noted for software setup. When using a printer, attach the original printer cable (male DB25) into the DaqBook connector labeled TO PARALLEL PRINTER.

Note: Printing cannot occur during data acquisition.

The DaqBook may be powered with a supplied AC adapter that plugs into any standard AC wall outlet. An isolated VDC source of 1-2 amps may also be used. Power requirements are +7-20 VDC for the DaqBook/100/112/120, +10-24 VDC for the DaqBook/216, and +9-18 VDC for the DaqBook/200/260. Before plugging unit in, make sure the power switch is in the “0” (OFF) position.

• If using an AC power adapter, plug it into an AC outlet and attach the low voltage end to the jack on

the DaqBook.

• If using another VDC source, make sure leads are connected to the proper DIN terminals.

To verify connections, turn ON the power switch by flipping the rocker- switch to the “1” position, and the POWER LED should light up. If using a printer, check operation by issuing a <PRINT SCREEN> or equivalent command.

Note: Software installation is necessary before the DaqBook can perform any functions.

Parallel Port Capabilities

The DaqBook/112, /120, /200, /216, and /260 (but not the /100) models can take advantage of enhanced parallel port (EPP) communication. Standard LPT ports on an IBM-compatible PC have 4-bit and 8-bit modes to read data from the printer port. The 8-bit mode is faster than the 4-bit, but not all printer ports support this mode. EPP ports are parallel ports with additional hardware that allows the DaqBook to communicate with the PC faster (3 to 10 times) than standard parallel ports.

EPPs require special hardware, and only certain computers are EPP-capable. Most laptop computers that use the Intel 386SL or 486SL chip set (which includes the 82360 I/O controller) are EPP-capable. For computers with plug-in card slots, EPP adapter cards are available. You may wish to consult your computer documentation for details about your machine and possible adapter cards. For more information about supported EPP hardware and machine-specific issues, refer to the README file supplied with the software.

Note: The EPPs may be configured for any available I/O address but must be configured for either

interrupt 5 or 7. The DaqBook driver does not support the use of interrupts 10, 11, 12, or 15.

In addition to supporting the special hardware required for EPP capability, some computers and parallel port cards come equipped with special BIOS or device drivers which support the EPP BIOS Draft Revision 3 (and possible Draft Revision 5) standard. This standard specifies a software level interface between applications and the EPP hardware itself. The DaqBook/DaqBoard software driver supports computers and parallel ports equipped with EPP BIOS Draft Revision 3.

Connector Pinouts

To gain access to DaqBook port connectors, signals can be connected via a CA-37-x cable through a D-shell 37-pin female connector or a DBK11 screw-terminal card with component sockets. The following tables detail P1, P2, and P3 pinouts and how each line is used.

Stacking Hardware

Using Dual-Lock Tabs and Splice Plates

For systems that make use of several data acquisition modules, stacking units together conserves space and simplifies cable runs. Such stacking can be facilitated with dual-lock tabs or splice palates.

• Dual-lock tabs. Dual-lock tabs, often referred to as Velcro,

stacking modules together. The tabs provide a convenient way to quickly add modules to [or remove modules from] a system. Dual-lock tabs are often used to attach a notebook PC to a module.

• Splice Plate Kits. Optional Splice Plate Kits are available through the factory. The kits include

metal plates that screw into the sides of modules to form a vertical rack of two or more modules. This method allows the “enclosure” to size itself as needed rather than wasting space in a 1-size-fits-all type of enclosure. A handle can be attached to the plate for convenience in portable applications.

Note that even when splice plates are used, dual-lock tabs are typically used to attach a notebook PC to the top-level acquisition module.

Using T-Cables

CAUTION

Turn power OFF to the Daq devices and externally connected equipment while connecting cables and setting configuration jumpers and switches or before opening the lid. Electrical shock or damage to equipment can result even under low-voltage conditions.

T-Cables are available in different lengths and can be used for linking two or more compatible devices together via the device’s 37-pin digital I/O connectors.

The bottom-end of the T-Cable is a dual-connector, consisting of both a female connector, and a 37-pin (male) connector. As seen in the following illustration, the T-Cable’s 37-pin (male) connector can be used for “Daisy-Chain” applications.

Each T-Cable comes with three sets of screws. These are designated (in the diagram) as: short, medium, and long. Use the short screws to secure the single, female-end of the cable to the device; and use the medium length screws to secure a cable’s “dual-end” connector. Use the long screws for daisy-chain applications (when you are connecting one T-Cable to another T-Cable).

Tighten screws snug only; do not over-tighten!

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:

CAUTION

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.

• signal conditioning

• analog output

• digital I/O

• channel expansion

• supplying powering to another acquisition device

• providing an interface for different connectivity.

Reference Notes: During software installation, Adobe

PDF versions of user manuals will automatically install onto your hard drive as a part of product support. The default location is in the Programs directory, which can be accessed from the Windows Desktop. Refer to 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.

Connecting DBKs to a DaqBook

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).

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.

Daq Systems 02-19-02 OMB-DBK Basics, pg. 5

15. If you are considering system expansion, review the DBK10, DBK41, and DBK60 document

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.

16. 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 Type Power Supply

The DBKs in this column use up to 15 VDC @ 2700 mA. This switching-mode power supply receives power from a 100 to 240 VAC source, at 50 to 60 Hz, and converts it to the required value.

15 VDC @ 900 mA

Transformer/Rectifier Type, Unregulated Power Supply

The DBKs in this column use up to15 VDC @ 900 mA. This transformer/rectifier type power supply receives power from a 110 to 125 VAC source, at 60 Hz, and converts it to the required value.

The DIN5 is the system’s basic power connector (see the following figure). The CA-115 is a 6-in. cable with a plug (male) DIN5 connector on both ends. The CA-115 is used to connect DBK32As [or DBK33s] in parallel when they are to be powered by the same power supply.

Note:

DIN5 connectors for LogBook, DBK34, and DBK34A have threaded retaining rings.

Note:

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.

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.

The module’s rechargeable power supply can

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.

CAUTION

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

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.

DBK34A module – provides 12 or 24 VDC with a 5.0 or 2.5 A-hr capacity (respectively). This device is

classified as a UPS / Battery module. It is an improved version of the earlier DBK34. Like the DBK34, the DBK34A can be used for in-vehicle testing where the vehicle’s electrical system will not affect acquisition device power during power during starter-current surge, or power-off.

Calculating Your System’s Power Needs

Use the chart below and the worktable on the next page to ensure your system will have sufficient power. If the load (calculated in the worktable) exceeds available power (from the chart at the right), you must add a power card or a module such as a DBK32A or DBK33.

DBK33 7500 mW

DBK34 5 A-hr in 12 V mode; fused at 8 A

DBK34A 5 A-hr in 12 V mode; fused at 8 A

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.
