FUNCTIONAL DESCRIPTION
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 pro-
gram 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.
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 pre-drilled mount-
ing holes match the PC/104 form factor (without the bus connections). This ensures easy installation using standard standoffs inside most enclosures or sys-
tems. 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 appli-
cations, an additional miniature USB input header is provided in parallel with the type B connector.
