1. Introduction
This manual contains information designed to familiarize you with the features and functions of the DI-4718B data
acquisition systems.
Features
DI-4718B series instruments are extremely versatile with multiple interface options, high resolution, expandability
with ChannelStretch™, and fast throughput rates. Features include:
•
Accepts up to 8 DI-8B amplifier modules accommodating virtually any industrial signal.
•
USB, Ethernet, and Power over Ethernet (PoE) interface options.
•
Ethernet models can be used as USB devices.
•
Up to 16-bit measurement resolution.
•
Up to 160,000 Samples per second maximum throughput rate.
•
Adaptable low-pass filter per channel - corner frequency set as a function of sampling rate.
•
A multi-purpose push-button for W

remote events and start/stop recording.
•
LED indication for easy notification of device status.
•
Free WinDaq/Lite data acquisition recording and playback software.
•
ChannelStretch™ Technology allows you to sync up to 16 DI-1120, DI-4108, DI-4208, or DI-4718B instruments
in any combination (requires same communications interface) with a total throughput of 480,000 samples per
second throughput, or more (requires unlock code for each device).*
•
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). ChannelStretch™ not
supported in stand-alone mode. Stand-alone data logging requires Unlock code to record more than 1 channel to
removable flash memory.
•
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™ when using WinDaq software. These restrictions do
not apply when programming the device yourself. ChannelStretch is not supported when recording to removable
flash memory.
Analog Inputs
DI-4718B models provide 8 fixed analog inputs designed specifically for DI-8B amplifiers that allow your analog
signals to be converted into 12 to 16-bit digital data via an on board A/D converter.

software to experience all the features in these versatile instruments. An Unlock
Code is required to synchronize multiple units when using WinDaq software. There are no restrictions when pro-
gramming the instruments yourself. An unlock code is also required to record more than a single channel to remov-
able flash memory.
Digital I/O
The DI-4718B 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
