1. Introduction
This manual contains information designed to familiarize you with the features and functions of the DI-4108 and DI-
4208 USB data acquisition systems.These systems are identical excluding gain ranges.
Features
Both the DI-4108 and DI-4208 data acquisition instruments are portable data recording modules that communicate
through your computer's USB and/or Ethernet port with stand-alone capability. Features include:
• 8 fixed differential analog inputs protected to 120 V rms.*
• USB, Ethernet, and Power over Ethernet (PoE) interface options.
• 7 digital ports protected to +25V.*
• Up to 16-bit measurement resolution (dependent on sample rate).
• The DI-4108 has programmable measurement ranges of ±200, ±500 mV, ±1, ±2, ±5, ±10 Volts.
• The DI-4208 has programmable measurement ranges of ±2, ±5, ±10, ±20, ±50, ±100 Volts.
• Up to 160 kHz maximum throughput sampling rate.
• Adaptable low-pass filter per channel - corner frequency set as a function of sampling rate
• A multi-purpose push-button for WINDAQ remote events and start/stop recording.
• Multi-color LED indication for easy notification of device status.
• Free WinDaq/Lite data acquisition recording software. Records up to four channels of data. Purchase an unlock
code to record more than four channels.
• Stand-alone option allows the user to configure a recording session through their PC then record data in the field
to removable flash memory via the USB drive port (without being connected to their PC). Stand-alone data log-
ging requires Unlock code to record more than 1 channel to removable flash memory.
• Counter channel.
• Frequency channel.
• ChannelStretch™ Technology allows you to sync up to 16 DI-1120, -4108, or -4208 instruments in any combina-
tion with a total throughput of 480kHz or more (requires unlock code for each device).*
• Included .Net Class supports programming under any .Net programming language.*
• Fully documented instrument protocol for programming the device in operating systems other than Windows.*
*WinDaq/Unlock required per device to use ChannelStretch™ and to record more than four total channels when
using WinDaq software. These restrictions do not apply when programming the device yourself.
Analog Inputs
Both the DI-4108 and DI-4208 feature eight differential channel inputs located on a single sixteen-position screw ter-
minal block for easy connection and operation. Gain measurement ranges of ±200, ±500 mV, ±1, ±2, ±5, ±10 Volts
for the DI-4108 or ±2, ±5, ±10, ±20, ±50, ±100 Volts for the DI-4208 are programmable on a per channel basis. Ana-
log channels are protected to 120 V rms.
Utilize the functionality of WINDAQ software to experience all the features encased in these small, inexpensive
instruments. An Unlock Code is required to record more than four channels of any type on either device or to syn-

chronize multiple units when using WinDaq software. There are no restrictions when programming the instruments
yourself.
Digital I/O
The DI-4208 contains seven digital ports, which may be used as a general-purpose digital input or for a specific func-
tion 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 and D5 are general purpose digital input ports. Please Note: Digital outputs are not supported
in WinDaq software. Each port may be configured as a switch using either the provided protocol or .Net class.
Software
All software required to record and playback waveforms is included with the purchase of any DI-4108 or 4208 data
acquisition system via download. Use the WinDaq Dashboard to access WinDaq Acquisition software or to setup the
stand-alone configuration.
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.
