FUNCTIONAL DESCRIPTION

The USB-AI16-16 is an ideal solution for adding portable, easy-to-install high-speed analog and digital I/O capabilities to any computer with a USB port. The unit is a USB 2.0 high-speed device, offering the highest speed available with the USB bus. The USB-AI16-16 is a 16-bit resolution A/D board capable of speeds up to 500kHz for its 16 single-ended or eight differential analog input channels. Each analog input channel can be independently configured to accept 8 different input ranges. Additionally, each channel contains its own analog ground pin which is helpful in reducing noise. A unique, real-time internal calibration system allows the card to continually adjust for offset/gain errors giving a more accurate reading. It is fully compatible with both USB 1.1 and USB 2.0 ports. The unit is plug-and-play allowing quick connect or disconnect whenever you need additional I/O on your USB port.

This small, compact, multifunction I/O board provides the user with everything needed to start acquiring, measuring, analyzing, and monitoring a variety of applications. The USB-AI16-16 data acquisition board can be used in many current real-world applications such as embedded equipment monitoring, precision PC-based and portable environmental measurements, and mobile data acquisition. Additional features include 16 digital I/O lines and a programmable 16-bit counter. The counter can be configured in a variety of modes and has the ability to use external signals for its inputs.

The USB-AI16-16 is designed to be used in rugged industrial environments but is small enough to fit nicely onto any desk or testing station. The board is PC/104 sized (3.550 by 3.775 inches) and ships inside a steel powder-coated enclosure with an anti-skid bottom.

• Embedded OEM

SOFTWARE

The USB-AI16-16 is plug-and-play which allows quick connect or disconnect whenever you need additional I/O on your USB port. The module utilizes a high-speed custom function driver optimized for a maximum data throughput of 1MBps that is 50-100 times faster than the USB human interface device (HID) driver used by many competing products. This approach maximizes the full functionality of the hardware along with capitalizing the advantage of high-speed USB 2.0. The USB-AI16-16 is supported for use in most USB supported operating systems and includes a free Linux (including Mac OS X) and Windows 98se/Me/2000/XP/2003 compatible software package. This package contains sample programs and source code in Visual Basic, Delphi, C++ Builder, and Visual C++ for Windows. Also incorporated is a graphical setup program in Windows. Third party support includes a Windows standard DLL interface usable from the most popular application programs, and includes example LabVIEW VIs. Embedded OS support include Windows XPe.

ACCESSORIES

The USB-AI16-16 is available with optional cable assemblies and screw terminal boards for easy-to-use, out of the box connectivity.
