    FUNCTIONAL DESCRIPTION

    The USB-DA12-8A is an ideal solution for adding portable, easy-to-install analog outputs to any computer with a USB port. The USB-DA12-8A is a USB 2.0 device, offering the highest speed available with the USB bus. It is fully compatible with both USB 1.1 and USB 2.0 ports. The board is plug-and-play allowing quick connection whenever you need additional I/O on a USB port.

    The USB-DA12-8A features 8 digital-to-analog converters (DACs) with both differential and single-ended outputs on separate connectors. The board features a variety of unipolar and bipolar ranges for each DAC giving the user a variety of options. The DACs can be updated individually or simultaneously. To ensure that there will not be excessive outputs to external circuits when the board is plugged in, automatic circuits limit analog outputs to zero volts. Power is supplied to the board via an external power supply which powers on board DC/DC converters which provide ±12V to the operational amplifiers on the board. The I/O wiring connections for USB-DA12-8A are via an industry standard, IDC type 26-pin, 16-pin, and 10-pin connectors.

    The USB-DA12-8A 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.

    OEM USB/104 FORM FACTOR

    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-DA12-8A OEM board can also be installed using standoffs inside other enclosures or systems.

    Applications

    • Portable
    • Laptop
    • Education
    • Laboratory
    • Industrial Automation
    • Embedded OEM

    SOFTWARE

    The USB-DA12-8A 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 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-DA12-8A 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.
