DI-1100 Hardware Manual
Introduction

1. Introduction
This manual contains information designed to familiarize you with the features and functions of the DI-1100 USB
data acquisition starter kit. These high-end Starter kits contain features and functionality normally reserved for more
expensive data acquisition systems.
Features
The DI-1100 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:
• 4 fixed differential analog inputs protected to ±100V (transient).
• Two dedicated digital I/O ports for Remote control protected to ±30V.
• ±10V full scale measurement range.
• 12-bit analog-to-digital resolution.
• 20kHz to 40kHz max sample rate per channel (dependent on number of channels enabled).
• A push-button to tag remote events in WINDAQ software.
• Three status LEDs for easy notification of system status.
• Free WinDaq recording and playback software allowing you to record at the full speed of the instrument.
• Included .Net Class supports programming the DI-1100 under any .Net programming language.
• Fully documented instrument protocol for programming the device in operating systems other than Windows.
Analog Inputs
The DI-1100 features four differential channel inputs located on a single sixteen-position screw terminal block for
easy connection and operation (other terminals used for digital I/O or reserved). Note: The DI-1100 does not support
Gain.
Utilize the functionality of WINDAQ software to experience all the features encased in these small, inexpensive
instruments.
Digital Inputs
The DI-1100 contains two digital lines (bits) for WINDAQ remote control operations (Remote Start/Stop and Remote
Events). Connect switch closures or discrete levels with a maximum input of 30V and a TTL level threshold. The
inputs float at 1 level, about 3.3V relative to the “-” terminal, and require sinking about 50uA to bring them down to
0.8V and guarantee a 0. When no Options Remote are enabled in WINDAQ, the Event input appears inverted in data
bit 0 and the Record input appears inverted in data bit 1 of data for the first enabled channel.
Software
All software required to record and playback waveforms is included with the purchase of any DI-1100 data acquisi-
tion starter kit via download.
WinDaq Dashboard
The WinDaq Dashboard utility allows you to start WinDaq software with your Dataq devices. Units available for syn-
chronized recording using ChannelStretch™ are shown in compatible blocks of devices (the DI-1100 does not sup-
port ChannelStretch or stand-alone data logging).

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 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, displays, and records waveform signals in real time at the
full sample rate of the DI-1100.
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
particular function or feature. Help topics discuss in detail each function available in the software.
