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.

Reference Note:

Programming topics are covered in the Programmer’s User Manual

(p/n OMB-1008-0901). As a part of product support, this manual is automatically

1-2 Overview

10-29-02 OMB-Daq Systems

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.

OMB-Daq Systems 10-29-02 Overview 1-3

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 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.

Daq Software

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

available:

• 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.

(1) Set Jumpers

(a) Place the unit on a flat, stable surface. Ensure no power or signal lines are connected.

(b) Remove cover screw(s), and slide the top cover plate free of the device. All jumpers are

accessible from above the board, and no further disassembly is required.

(c) Set jumpers JP1 through JP4 as needed for your application. Jumper configuration options

follow shortly. Note that jumpers are clearly labeled on the actual motherboards.

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

related settings are made via software.

(d) Leave JP5, JP6, and JP7 in their default positions. JP5 (Time Base Selection) default position

is for 1 MHz. JP6 (Watchdog Timer Enable/Disable) default position selects “disabled.”

JP7 concerns calibration. See user’s manual prior to changing the settings of these three

jumpers.

(e) Replace and secure the cover before applying power and signals.

Motherboard Jumper Locations

Note: DaqBook/112 and DaqBook/216 boards are physically smaller than the other boards.

JP1 – External Analog Expansion Power

If analog option cards (DBKs) are used, JP1 jumpers are set to provide +15 and -15 VDC to the cards.

If using a DBK32A or DBK33 Power Supply Card, remove all jumpers from JP1.

If no cards are being used, the counter/timer CTR0 is available, and JP1 must be set as shown in the

following figure.

CAUTION

Placing the jumpers on -OCTOUT and -OCLKIN could damage the 8254 timer chip! If either

a DBK32A Auxiliary Power Supply or a DBK33 Triple-Output Power Supply Card is used, the JP1

shunt jumpers must be removed, otherwise timer chip damage will occur. Refer to the DBK32A,

DBK33, and Power Management sections of your user’s manual for more information.

OMB-DaqBook User’s Manual 10-29-02 Setup and Startup 2-3

JP2 – DAC Reference Voltage and SSH (Simultaneous Sample and Hold)

JP2 selects an Internal (default) or External reference voltage for the two separate

analog outputs.

JP2 also selects SSH (default) for applications using one or more of the following:

DBK2, DBK4, DBK5, DBK7, DBK17, DBK50, or DBK51.

We recommend that you leave these jumpers at the factory default setting

Configuration and change the DaqBook configuration settings to those that work properly.

Test results have two components: Resource Tests and Performance Tests.

Resource Tests

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 resource

availability or a resource conflict.

• Base Address Test – Tests the base address for the selected parallel port. Failure of

this test may indicate that the parallel port 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 parallel port to generate interrupts.

Failure of this test may indicate that the parallel port may be currently unable to

generate the necessary hardware interrupt, while other parallel port devices may

work OK in this mode. Some parallel port devices (such as printers) do not require

interrupts to work properly. See relevant operating system and computer

manufacturer’s documentation to correct the problem.

10-29-02 OMB-DaqBook User’s Manual

Performance Tests

Performance tests are intended to test various DaqBook 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.

These rates depend on the selected parallel port protocol and will vary according to port

hardware capabilities.

• ADC FIFO Input Speed – tests the maximum rate at which data can be transferred

from the DaqBook’s internal ADC FIFO to computer memory through the parallel

port. 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 the DaqBook’s Digital I/O ports to computer memory through the

parallel port. 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 the DaqBook’s Digital I/O ports through the

parallel port. Results are given in bytes/second.

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.

Reference Notes:

The section, External Analog Expansion Power (JP1), explains how to set JP1, based on

power use in the system.

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.

• DaqBook/112 and DaqBook/216 provide 1 slot for an expansion DBK card.

• DaqBook/100, DaqBook/120, and DaqBook/200 do not have an expansion slot, but do have

24 general-purpose digital I/O channels (expandable up to 192), 16 high-speed digital inputs,

and 5 frequency/pulse I/O channels.

• DaqBook models /120, /200, and /260 have EPP (Enhanced Parallel Port) capability.

• DaqBook/260 has 3 expansion slots for DBK cards.

• DaqBook/100, DaqBook/112, and DaqBook/120 are 12-bit.

• DaqBook/200, DaqBook/216, and DaqBook/260 are 16-bit.

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 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 DaqBook’s 37-pin P1 I/O connector.

Reference Note: Connector Pinouts begin on page 3-8.

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.

Indicators

POWER This LED lights when power is applied to the DaqBook and the power switch is in

the “1” (ON) position.

P1-P2-P3 ACTIVE This LED lights when the DaqBook is in an active state. This LED is off when

the DaqBook is disabled or in the printer-pass-through mode. P1, P2, and P3

are software accessible from the computer.

BUFFER OVERRUN This LED lights for a buffer overrun error. This occurs when A/D signals are

converted faster than the PC collects the data. Depending on the application,

this indication may not be an error.

A/D ACTIVE This LED lights during an A/D scan sequence. If the sequence has a low

number of steps and occurs infrequently, this indicator will only flash briefly.

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. Silk-

screening 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.
