DI-2108-P Hardware Manual

Introduction

1. Introduction

This manual contains information designed to familiarize you with the features and functions of the DI-2108-P USB

data acquisition system.

Features

The DI-2108-P data acquisition instrument is a portable data recording module that communicates through your com-

puter's USB port. Power is derived from the interface port so no external power is required. Features include:

• 8 fixed differential analog inputs protected to ±150V (transient).

• Free WinDaq/Lite data acquisition recording software. Records up to four channels of data. Purchase an unlock

code to record more than four channels.

• 7 digital ports protected to +25V.

• 16-bit measurement resolution

• Programmable measurement ranges of ±2.5, ±5, ±10, 0-5, and 0-10 Volts.

• Up to 160 kHz maximum throughput sampling rate.

• A push-button to tag remote events in WINDAQ software.

• LED indication for easy notification of device status.

• Counter channel for counter/timer applications up to 65,536 points.

• Frequency/Rate channel measuring 10Hz to 50kHz.

• ChannelStretch™ Technology allows you to sync up to 16 units with a total throughput of 480kHz or more

(requires unlock code for each device).

• Included .Net Class supports programming the DI-2108-P under any .Net programming language.*

• Fully documented instrument protocol for programming the device in operating systems other than Windows.*

*ChannelStretch requires that each device be unlocked when used with WinDaq software. WinDaq unlock is not

required for ChannelStretch if programming devices yourself using the .Net class or instrument protocol.

Analog Inputs

The DI-2108-P features eight differential channel inputs located on a single sixteen-position screw terminal block for

easy connection and operation. Measurement ranges of ±2.5, ±5, ±10, 0-5, or 0-10 Volts are programmable on a per

channel basis. Analog channels are protected to ±150 V dc or peak ac.

Utilize the functionality of WINDAQ software to experience all the features encased in these small, inexpensive

instruments. Unlock code required to record more than four channels of any type.

Digital I/O

The DI-2108-P contains seven digital ports, that may be used individually as a general-purpose digital input or for a

specific function as designated on the device. Digital port D0 may be used for WinDaq Events; Digital port D1 may

be used for WinDaq remote Start/Stop; Digital port D2 may be used for rate measurements; Digital port D3 may be

used for counts; Digital ports D4-D6 are general purpose digital input port. Please Note: Digital outputs are not sup-

ported in WinDaq software. Each port may be configured as a switch using third-party software.

DI-2108-P Hardware Manual

Introduction

Software

All software required to record and playback waveforms is included with the purchase of any DI-2108-P data acqui-

sition system.

WinDaq Dashboard

The WinDaq Dashboard utility allows you to start WinDaq software, configure and start stand-alone data logging,

and set the instrument clock to your PC. Units available for synchronized recording using ChannelStretch™ are

shown in compatible blocks of devices.

WINDAQ®Recording and Playback Software

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

instrument. WINDAQ software is an invaluable resource to record and analyze your data and is available for free from

our web site (www.dataq.com).

WINDAQ Lite Data Acquisition software (free) can be used to record waveforms directly and continuously to disk

while monitoring a real time display of the waveforms on-screen. It operates, displays, and records up to four chan-

nels in real time. An optional unlock code is available to record the rest of the channels on the device or to allow you

to sync multiple units.

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.

Help

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

F1 key with any pull-down menu item selected. This will take you directly to the Help topic most relevant to that par-

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