Safety Precautions - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
To avoid electrical shock, always disconnect the power from the PC chassis
before manual handling. Do not touch any components on the CPU card or
other cards while the PC is powered on.
Disconnect the power before making any configuration changes. A sudden rush
of power after connecting a jumper or installing a card may damage sensitive
electronic components.

1.1 Introduction
Thank you for buying the Advantech’s USB-4751/4751L data acquisition module.
The Advantech USB-4751/4751L is a powerful data acquisition (DAS) module for the
USB port. It features a unique circuit design and complete functions for data acquisi-
tion and control.
1.2 Hardware Features
USB-4751/4751L features excellent measurement & control functions:
48/24 digital input/output channels
50-pin box header
Interrupt handling
Programmable Counter/Timer
Supports both dry and wet contact
Compatible with USB 1.1/2.0
Bus-powered
1.3 Software Overview
Advantech offers device drivers, SDKs, third-party driver support and application
software to help fully exploit the functions of your DAQ devices. All these software
packages are available on Advantech website: http://www.advantech.com/.
The Advantech Navigator is a utility that allows you to set up, configure and test your
device, and later stores your settings in a proprietary database.
1. To set up the I/O device for your card, you could first run the Advantech Naviga-
tor program (by accessing Start/Programs/Advantech Automation/DAQNavi/
Advantech Navigator). The settings could also be saved to XML file, that can be
loaded in the applications using LoadProfile API.
2. You can then view the device(s) already installed on your system (if any) on the
Installed Device tree view. If the software and hardware installation are com-
pleted, you will see the device in the Installed Devices list.
Note! You can install up to sixteen USB-4751/4751L’s to a system because of
the maximum number limit of the device BoardID.
Note! The power output of an USB port is 500 mA, while the USB-4751/4751L
requires 500mA (Max.). This means that if an USB hub is used, it will
need an external power supply to support more than one USB-4751/
4751L device.
Note! For detailed specifications of USB-4751/4751L, please refer to Appendix
A, Specifications.

USB-4751/4751L User Manual 4
2.1 Unpacking
After receiving your USB-4751/4751L package, please inspect its contents first. The
package should contain the following items:
USB-4751/4751L Module
Shielded USB 2.0 Cable (1.72 m)
User Manual
The USB-4751/4751L Module harbors certain electronic components vulnerable to
electrostatic discharge (ESD). ESD could easily damage the integrated circuits and
certain components if preventive measures are not carefully paid attention to. Before
removing the module from the anti-static plastic bag, you should take following pre-
cautions to ward off possible ESD damage:
Touch the metal part of your computer chassis with your hand to discharge static
electricity accumulated on your body. One can also use a grounding strap.
Make contact between the anti-static bag and ground before opening.
After taking out the module, you should first:
Inspect the module for any possible signs of external damage (loose or damaged
components, etc.). If the module is visibly damaged, please notify our service depart-
ment or our local sales representative immediately. Avoid using a damaged module
with your system.
Avoid physical contact with materials that could hold static electricity such as
plastic, vinyl and Styrofoam.
2.2 Driver Installation
The driver package could be found on Advantech Support Portal (https://www.advan-
tech.com/support). Search for USB-4751/4751L on the support portal, then the corre-
sponded driver/SDK package could be found. You’ll get the XNavi installer after the
download session finishes.
Execute the installer, then it will guide you through the session. You can choose the
device and software components you’d like to install in the system (Figure 2.1). After
the selection, click on “start” to begin the installation.
