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-4750 data acquisition module. The
Advantech USB-4750 is a powerful data acquisition (DAS) module for the USB port.
It features a unique circuit design and complete functions for data acquisition and
control.
1.2 Hardware Features
USB-4750 features excellent measurement & control functions:
32 isolated digital input/output channels
High-voltage isolation up to 2,500 VDC on all channels
Dry/wet contact support
Interrupt handling capability
High-sink current for isolated output channels (200mA max./Channel)
Digital output value retained after hot system reset
Programmable Power-Up States for output channels
Wiring terminals on module
Compatible with USB 1.1/2.0 (Supports USB 1.1 data transfer rate)
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-4750'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-4750
requires 350 mA (Max.). This means that if an USB hub is used, it will
need an external power supply to support more than one USB-4750
device.
Note! For detailed specifications of USB-4750, please refer to Appendix A,
Specifications.

2.1 Unpacking
After receiving your USB-4750 package, please inspect its contents first. The pack-
age should contain the following items:
USB-4750 Module
Shielded USB 2.0 Cable (1.72 m)
User Manual
The USB-4750 Module harbors certain electronic components vulnerable to electro-
static discharge (ESD). ESD could easily damage the integrated circuits and certain
components if preventive measures are not carefully paid attention to. Before remov-
ing the module from the anti-static plastic bag, you should take following precautions
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.
