features and benefits
The PIO-D144U universal PCI card supports 3.3 V/5 V PCI bus.
These cards provide 144 TTL digital I/O lines that are grouped into eighteen 8-bit bi-directional ports.
Each group of three 8-bit ports is arranged on the connector as Port A (PA), Port B (PB) and Port C (PC), respectively, and all ports are configured as inputs Ports on power-up or after a reset. The PIO-D144U provides six connectors for I/O wiring.
The PIO-D144U cards include an onboard Card ID switch that enables the board to be recognized via software if two or more boards are installed in the same computer. The PIO-D144U also adds pull-high/low jumpers allow the DI status to be predefined instead of remaining floating if the DI channels are disconnected or interrupted. The cards support various OS versions, such as Linux, DOS, Windows.
DLL and Active X control together with various language sample program based on Turbo C++, Borland c++, Microsoft C++, Visual C++, Borland Delphi, Borland C++ Builder, Visual Basic, C#.NET, Visual Basic.NET and LabVIEW are provided in order to help users to quickly and easily develop their own applications.
