The board features jumper selectable ±5V or 0-10V ranges for the DACs. Additional ranges can be achieved as factory options giving the user a variety to select from. The DACs can be updated individually or simultaneously. Each channel can be factory calibrated or calibrated specific to the user’s requirements through software. 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 until initialized via software command. 16 digital I/O lines are provided on a female 37-pin D type connector in two groups of 8 bits. Both digital bytes are individually configured as inputs or outputs. Each 8-bit digital I/O group can be configured for either 5V TTL or 3.3V LVTTL signaling via jumper selection. A 2-channel 16-bit analog-to-digital converter (ADC) is also optionally available. The USB-AO16-16A 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. 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-AO16-16A OEM board can also be installed using standoffs inside other enclosures or systems. ACCESSORIES The USB-AO16-16A is available with optional cable assemblies and screw terminal boards. SOFTWARE The USB-AO16-16A is plug-and-play which allows quick connect or disconnect whenever you need additional I/O on your USB port. The module utilizes a 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-AO16-16A is supported for use in most operating systems and includes a free Linux and Windows 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 includes Windows XPe.
