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

1-2 Overview

02-13-02

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

02-13-02

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-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.

OMB-DaqBoard-ISA User’s Manual

(1) Configure the ISA-DaqBoard

(Set Jumpers and Configure the DIP-Switch)

JP1 - External Analog Expansion Power

&$87,21

Placing the jumpers on JP1’s 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

the user documentation for more information.

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 figure.

JP1 Configurations

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

&$87,21

In regard to JP2, the SSH jumper must be removed if you are using EXT DAC0 or EXT

DAC1. See the user’s manual for details.

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 the JP2 jumpers at their factory default setting

(see figure at right). Refer to the JP2 material in chapter 3 prior to making

changes.

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.

Overview

The DaqBoard/100A, /112A, /200A, and /216A are 100 kHz ISA-bus plug-in boards that provide analog-

to-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:

•

DMA

•

Fast I/O to data memory via block move instruction REP INSW.

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