The USB-AI12-16A 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 currently available with the USB bus. The USB-AI12-16A is a 12-bit resolution A/D board capable of speeds up to
500kHz for its 16 single-ended or 8 differential analog inputs. Each channel can be independently software configured to accept 8 different input ranges. Additionally,
each channel includes its own analog ground pin on the I/O connector which is helpful in reducing noise. A unique, real-time internal calibration system allows the card to
continually compensate for offset/gain errors giving a more accurate reading. The unit is plug-and-play allowing a quick connection whenever you need additional I/O on
the convenience of a USB port.
This small, compact, multifunction I/O board provides the user with everything needed to start acquiring, measuring, analyzing and monitoring in a variety of applications.
The USB-AI12-16A 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 to trigger and control the scanning of its inputs.
The USB-AI12-16A 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.
The OEM (board only) version is perfect for a variety of embedded applications. What makes the OEM option unique is that its PCB size and mounting holes
match the PC/104 form factor (without the bus connections). This allows our rugged digital board to be added to any PCI-104 or PC/104 stack by connecting it
to a simple USB port usually included on-board with embedded CPU form factors such as EBX, EPIC, and PC/104. This is especially important since many
newer CPU chipsets do not support ISA and have plenty of USB ports. The USB-AI12-16A OEM board can also be installed using standoffs inside other enclosures or systems.
The USB-AI12-16A is available with optional cable assemblies and screw terminal boards for easy-to-use, out of the box connectivity.
The USB-AI12-16A is plug-and-play which allows quick connect or disconnect whenever you need additional I/O on your USB port. The module utilizes a highspeed custom function driver optimized for a maximum data throughput 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-USB-AI12-16A is supported for use in most USB supported operating systems and includes a free Linux 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. Embedded OS support include Windows XPe.
