This USB board is an ideal solution for adding portable, easy-to-install digital I/O capabilities to any computer with a USB port. The board is a USB 2.0 high
speed device, offering the fastest speed available with the USB bus. It is fully compatible with both USB 1.1 and USB 2.0 ports. The card is plug-and-play
allowing quick connect/disconnect whenever you need additional I/O on your USB port.
The board features 96 or 48 bits of TTL-compatible digital I/O with high-current capabilities. Each digital port can be programmed to accept inputs or to drive
outputs in twelve or six 8-bit ports. Power is supplied to the card via the USB cable, or for higher source current capabilities, an external power option may be
ordered. The I/O wiring connections are via two or four industry standard 50-pin connectors. For external circuits, fused +5VDC power is available at pin 49 of
each I/O connector. The resettable fuse is rated at 0.5A.
All I/O lines are buffered by a type 74ABT543A tristate buffer transceiver capable of sourcing 32 mA or sinking 64 mA. The buffers are configured under program control for input or output. Jumper selected resistors permit configuration of each 24-bit / 50-pin connector group for pull-up (to +5 VDC), pull-down (to
ground) or floating depending on the application requirement. Pull-ups are useful for contact monitoring and assure that there are no erroneous outputs at
power-up until the card is initialized by system software.
Unlike most USB digital I/O products which primarily use a human interface device (HID) driver, we provide an easy to use, Windows/Linux-based, custom
function driver capable of updating all 96-bits approximately 4000 times per second.
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 pre-drilled mounting holes match the PC/104 form factor (without the bus connections). This ensures easy installation using standard standoffs inside most enclosures or systems. The board can be added to any PC/104, PCI-104, or PCI/104-Express stack by connecting it to a USB 2.0 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-DIO-96 and USB-DIO-48 OEM board can also be installed using standoffs inside other enclosures or systems. For embedded OEM type applications, an additional miniature USB input header is provided in parallel with the type B connector.

PC/104 - USB
Available accessories include flat ribbon cables and DIN-rail mountable screw terminal boards. Also available is our low cost IIB-24 which will add optical
isolation to any standard 24-channel digital I/O port on a 50 pin connector. To make use of the miniature embedded USB header connector, we offer a 6’ type
A to mini cable.
The USB-DIO-96 and USB-DIO-48 are 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 highspeed USB 2.0. These boards are 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 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 includes Windows XPe.
