FUNCTIONAL DESCRIPTION
This PC104 plus board features 96 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. 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.
ACCESSORIES
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.
SOFTWARE
This board is supported for use in most operating systems and includes a free Linux and Windows 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. Em-
bedded OS support includes Windows XPe.
