Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the
products from damage.
1. To avoid electrical shock, always disconnect the power from your
PC chassis before you work on it. Don't touch any components on
the CPU card or other cards while the PC is on.
2. Disconnect power before making any configuration changes. The
sudden rush of power as you connect a jumper or install a card may
damage sensitive electronic components.

CHAPTER
Introduction
This chapter will provide information
on the features of the DAS module, a
quick start guide for installation, and
some brief information on software and
accessories for the USB-4761 Module.
Sections include:
• Features
• Applications
• Installation Guide
• Software Overview
• Device Driver Programming
Chapter 1 Introduction
Thank you for buying the Advantech’s USB-4761 data acquisition module. The Advantech USB-4761 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.
1.1 Features
USB-4761 has the most requested measurement & control functions:
• 8 relay output (Form C) and 8 isolated digital input channels
• LED indicators to show activated relays
• High-voltage isolation on input channels (2,500 VDC)
• High ESD protection (2,000 VDC)
• Wide input range (5 ~ 30 VDC)
• Interrupt handling capability
• Supports USB 2.0
• Bus-powered
• Wiring terminal on Modules
Note: You can install up to sixteen USB-4761’s to a
system because of the restriction of device
BoardID
Note: The power output of an USB port is 500 mA,
while the USB-4761 requires 400mA (Max.). This
means that if an USB hub is used, it will need an
external power supply to support more than one
USB-4761 device.
USB-4761 User Manual 2
1.1.1 Robust Protection
The USB-4761 digital input channels feature a robust isolation protection
for industrial, lab and machinery automation applications. It durably
withstands voltage up to 2,500 VDC, preventing your host system from
any incidental harms. If connected to an external input source with surge
protection, the USB-4761 can offer up to a maximum of 2,000 VDC ESD
(Electrostatic Discharge) protection.
1.1.2 Wide Input Range
The USB-4761 has a wide range of input voltage from 5 to 30 VDC, and it
is suitable for most industrial applications with 12 and 24 V
age.

DC
1.1.3 Reset Protection for Industrial Applications
When the system has undergone a hot reset (i.e. without turning off the
system power), USB-4761 can either retain outputs values of each channel, or return to its default configuration as open status, depending on its
onboard jumper setting. This function protects the system from wrong
operations during unexpected system resets.
1.1.4 Plug & Play Function
USB-4761 is a portable Plug-&-Play device that fully complies with the
USB 2.0 specification. During module installation, all bus-related configurations such as base I/O address and interrupts are conveniently taken
care of by the Plug-&-Play function. You have virtually no need to set
any jumpers or DIP switches.
Note: For detailed specifications of USB-4761, please
refer to Appendix A, Specifications.

1.2 Applications
• Industrial On/Off control
• Switch status sensing
• Digital I/O control
• Industrial and lab automation
• SMT/PCB machinery
• Semi-conductor machinery
• PC-based Industrial Machinery
• Testing & Measurement
• Laboratory & Education
• External relay driving
1.3 Installation Guide
Before you install your USB-4761 module, please make sure you have
the following necessary components:
• USB-4761 DAS Module
• USB-4761 User Manual
• Shielded USB 2.0 cable (1.8 m)
• Driver software Advantech DLL drivers (included in the companion
CD-ROM)
• Personal computer or workstation with a USB port (running Windows
2000, or XP)
Some application software is also available for enhanced operation. USB4761 works with ActiveDAQ, ActiveDAQ Pro, and other third-party
software packages.
After you have the necessary components and maybe some accessories
for enhanced operation of your USB DAS module, you can then begin the
installation procedure. Figure 1.1 on the next page provides a concise
flow chart to give a broad picture of the software and hardware installation procedures.

1.4 Software Overview
Advantech offers a rich set of DLL drivers, third-party driver support and
application software to help fully exploit the functions of your USB-4761
module:
• Device Drivers (on the companion CD-ROM)
• LabVIEW driver
• Advantech ActiveDAQ
• Advantech ActiveDAQ Pro
1.4.1 Programming Choices for DA&C Module:
You may use Advantech application software like Advantech Device
Drivers. On the other hand, advanced users are allowed to use registerlevel programming as another option, although this is not recommended
due to its laborious and time-consuming nature.
1.4.2 Device Drivers
The Advantech Device Drivers software is included on the companion
CD-ROM. Advantech’s Device Drivers features a complete I/O function
library to help boost your application performance. The Advantech
Device Drivers for Windows 2000/XP works seamlessly with development tools such as Visual C++, Visual Basic, Inprise C++ Builder, and
Inprise Delphi.
