Introduction

1. Introduction

Congratulations on your purchase of the DI-718B data logger/data acquisition system or DI-718Bx data logger/data

acquisition system. The DI-718B is designed specifically to accept DI-8B modules — the world’s smallest fully func-

tional isolated analog signal conditioner.

Features

Common features of the DI-718B and the DI-718Bx are:

• 4,800 Hz maximum sampling rate—14,400 Hz when in Stand-alone data logger operating mode.

• 0.048 Hz minimum sampling rate—0.0017 Hz when in Stand-alone data logger operating mode.

• 14-bit A/D converter for high resolution measurement accuracy.

• The Stand-alone option allows the user to configure a recording session through their PC then record data in

the field to an SD card (without being connected to their PC).

The DI-718B has the following additional features:

• Accepts up to 8 DI-8B amplifier modules accommodating virtually any industrial signal.

• USB or Ethernet interface options.

The DI-718Bx has the following additional features:

• Accepts up to 16 DI-8B amplifier modules accommodating virtually any industrial signal.

• Ethernet interface (optional external USB to Ethernet converter available — part number 101014-EA).

Analog Inputs

DI-718B models provide 8 fixed single-ended analog inputs that allow your analog signals to be converted into 14-bit

digital data via an on board A/D converter. Differential input is not supported.

DI-718Bx models provide 16 fixed single-ended analog inputs that allow your analog signals to be converted into 14-

bit digital data via an on board A/D converter. Differential input is not supported.

Digital Inputs

The DI-718B provides two digital input channels for Remote Control Operations (Remote Start/Stop and Remote

Events) that may be accessed using the Built-In Remote Control Jack (see "Built-In Remote Control Jack" on page

19). Remote Control configuration and setup is easily accessible in both WINDAQ Acquisition software and in the

Dataq Instruments Hardware Manager (when configuring the instrument for Stand-alone operation).

The DI-718Bx provides 8 software-programmable digital lines (bits) for input/output operations. These lines provide

an interface for the transfer of data between user memory and a peripheral device connected to the instrument. Digital

inputs can monitor alarms or sensors with TTL outputs, while digital outputs can drive TTL inputs on control or mea-

surement equipment. Remote control can be utilized with bits 0 and 1 and is easily accessed using WINDAQ Acquisi-

tion software or, for stand-alone models, in the stand-alone setup panel. To avoid using an analog input channel for

Digital I/O, Channel 17 may be enabled as the digital channel. To use the Remote Control features in WINDAQ Acqui-

sition software either Channel 1 or Channel 17 must be configured as the Digital Input channel. Access digital I/O

ports from the rear panel of the device. See "Digital I/O and Monitor Out" on page 28. Digital I/O bits are not avail-

able in Stand-alone mode except for Remote Control functions.

Introduction

Software

All software required to record and playback waveforms is included with the purchase of any DI-718 model including

WINDAQ Acquisition and Playback software and the Dataq Instruments Hardware Manager.

WINDAQ®Recording and Playback Software

WINDAQ Acquisition and WINDAQ Waveform Browser allow you to record and playback data acquired through your

instrument. Whether using a Stand-alone model or a PC-connected instrument, WINDAQ is an invaluable resource for

analyzing data. A special version (see "WinDaq Waveform Browser for MMC" on page 37) of WINDAQ Waveform

Browser (free) is required to read waveform data recorded to a Memory Card but is easily transferred to the standard

version for more analytical features.

WINDAQ Acquisition software can be used to record waveforms directly and continuously to disk while monitoring a

real time display of the waveforms on-screen. It operates and displays waveform signals in real time at the full sample

rate of the instrument being used. There are two versions of WINDAQ Acquisition software available for use with DI-

718 Instruments: WINDAQ/Lite and WINDAQ/High Speed option. WINDAQ/Lite is free but is restricted to recording

throughput rates of 1108 Hz with a DI-718. WINDAQ/High Speed option is an extra-cost option allowing you to

record data at the speed of your data acquisition system. When you install the software, a trial version of WINDAQ/

High Speed is automatically installed allowing you to run the software for a limited time. Activation is required for

continued use to ensure compliance with the Software License Agreement. This software is accessed through the

Dataq Instruments Hardware Manager which can be found in the Start menu under the WINDAQ program group

called Dataq Instruments Hardware Manager.

WINDAQ Waveform Browser playback software (also known as “WWB”) offers an easy way to review and analyze

acquired waveforms. A built-in data file translator allows the user to display multiple waveforms acquired by

WINDAQ Acquisition software or any of a wide range of data acquisition packages. The software’s disk-streaming

design allows data files of any length to be graphically displayed rapidly, in normal or reverse time directions. Seven

standard cursor-based measurements, frequency domain, and statistical analysis functions help simplify waveform

analysis and interpretation. WINDAQ Waveform Browser is free and installed when installing WINDAQ Software.

The DATAQ Instruments Hardware Manager

The DATAQ Instruments Hardware Manager allows you to effectively manage and run multiple instruments installed

and connected to your PC or your Network—or even over the internet. This software can be found in the Start menu

under the WINDAQ program group called Dataq Instruments Hardware Manager. Access WINDAQ Acquisition

software, upload data from your memory card, check the status of your memory card, format your memory card, con-

figure a Stand-alone data acquisition session, and more in this easy-to-use point and click environment. View the

Help files by clicking on View Help in the Help menu or by pressing F1.

Help

All WINDAQ software utilizes context-sensitive help. Help maybe accessed through the Help menu or by pressing the

F1 key with any feature selected. This will take you directly to the Help topic most relevant to that particular function

or feature. Help topics discuss in detail each function available in the software.
