1. Introduction
This manual contains information designed to familiarize you with the features and functions of the DI-1110 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-1110 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 or 8 fixed differential analog inputs protected to ±100V (transient).*
• ±10V full scale measurement range.
• 12-bit analog-to-digital resolution.
• 7 digital ports* protected to +25V: Two dedicated for WINDAQ remote control operations; One dedicated to
WINDAQ rate measurements; and One dedicated to WINDAQ counter measurements.
• Up to 160 kHz maximum throughput sampling rate.
• A push-button to tag remote events in WINDAQ software.
• LED indication for easy notification of system status.
• Free WinDaq/Lite data acquisition recording software.
• Included .Net Class supports programming the DI-1110 under any .Net programming language.
• Fully documented instrument protocol for programming the device in operating systems other than Windows.
* WinDaq/Unlock required to record more than four total channels when using WinDaq software.
Analog Inputs
The DI-1110 features eight differential channel inputs (WinDaq/Unlock required to record more than four total chan-
nels when using WinDaq software) 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-1110 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-1110 contains seven digital ports (WinDaq/Unlock required to record more than four total channels when
using WinDaq software), which may be used as a general-purpose digital inputs or for a specific function as desig-
nated on the device. Digital port D0 is reserved for WinDaq Events; Digital port D1 is reserved for WinDaq remote
Start/Stop; Digital port D2 is reserved for rate measurements; Digital port D3 is reserved for counts; Please Note:
Digital outputs are not supported in WinDaq software. Each port may be configured as a switch using third-party
software.
Software
All software required to record and playback waveforms is included with the purchase of any DI-1110 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-1110 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-1110.
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.

Please note: The SD card slot is not used in the DI-1110. Allowing foreign materials to enter the device through the
SD card slot may result in damage to the instrument.
Mini-B USB Connection
Use the supplied USB cable to connect and power the instrument through your computer’s USB port.
Screw Terminals
All input signal connections are made to the 16-port screw terminals. Each terminal is labeled on the instrument case.
CAUTION
Do not touch the input terminals after signal cables are connected to the system under test,
since it will cause an electric shock.
To avoid ESD damage in handling the device, take the following precautions:
Ground yourself with a grounding strap or by touching a grounded object before and during
your handling of the instrument.

Connecting Signal Leads
Connect signal leads to the DI-1110:
1. Insert the stripped end of a signal lead into the desired terminal directly under the screw.
2. Tighten the pressure flap by rotating the screw clockwise with a small screwdriver. Make sure that the pressure
flap tightens only against the signal wire and not the wire insulation. Do not over-tighten.
3. Tug gently on the signal lead to ensure that it is firmly secured.
When an input signal is connected and WINDAQ Acquisition software is run, WINDAQ’s real time display immedi-
ately reveals the input waveform on your computer’s monitor.

Once the switch closure or TTL signal is connected, activate Remote Events through WINDAQ Acquisition Software.
Events may be automatically placed on the rising or falling edge of the trigger signal. Use the menu command
Options > Remote Events + to set WINDAQ to place event markers on low-to-high transitions of the Event input.
Use the menu command Options > Remote Events - to set WINDAQ to place event markers on high-to-low transi-
tions of the Event input.
Event markers may also be placed in your data file manually by pressing the push button on the DI-1110 Instrument.
You must enable Remote Events in WINDAQ to use the button (use the menu command Options > Remote Events

WINDAQ Remote Storage (Rcrd/D1)
To use a switch closure or TTL signal to begin recording data remotely, connect signal leads to the appropriate
Remote Control Record terminals on the DI-1110 as shown below.
Once the switch closure or TTL signal is connected, activate Remote Storage (Record) through WINDAQ Acquisition
Software. Storage to Disk may be automatically placed on the rising or falling edge of the trigger signal. Use the
menu command Options > Remote Storage 1 to set WINDAQ to begin recording on low-to-high transitions of the
Record input. Use the menu command Options > Remote Storage 0 to set WINDAQ to begin recording on high-to-
low transitions of the Record input.

box will display an “R” when enabled.
Connect any TTL pulse stream (25 VDC max) to the D2 Rate channel on the DI-1110.
Select Channel 10 in the channel display, then select Edit > Channel Settings in the menu to specify a full scale
range for the Rate channel. Ranges of 10, 20, 50, 100, 200, 500, 1000, 2000, 5000, 10000, 20000, and 50000 Hz are
available. Choose a range that comes closest to your expected full scale rate or frequency. For example, if you need to
measure the output of a flow meter that can measure a maximum flow rate of 100 gallons per minute, and the output
frequency at that rate is 100 Hz, you would choose the 100 Hz range setting. A range setting of 200 Hz full scale sac-

rifices half of the instrument's resolution at 200 gallons per minute, and a range of 50 Hz allows measurements to
only 50 gallons per minute full scale.
Check the "Cycles/min" box to display and select frequencies reported in cycles per minute instead of cycles per sec-
ond (the measurement interval remains the same). Tachometer measurements in units of RPM (revolutions per min-
ute) is just one example that benefits from selecting this option. For example, if the 100 Hz range setting is selected
and "Cycles/min" is checked, the full scale range is actually 6000 cycles per minute.
Please Note: To measure the maximum rate, which is defined as 2 times the Maximum Sample Rate/Channel , the
current values of Maximum Sample Rate/Channel divided by Sample Rate per Channel MUST be an integer.

Enable channel 11 to record Counts, or the number of falling-edge transitions that are applied to this input. The count
may be reset via WINDAQ software or under program control as necessary. Click on Edit > Channels in the WINDAQ
