features and benefits
The PIO-D24U supports 3.3 V/5 V PCI bus.
The PIO-D24U consists of three 8-bit bi-direction ports.
The 8-bit ports are named as port A (PA), port B (PB) and port C (PC) respectively.
All ports are configured as inputs upon power-up or reset. The PIO-D24U has a Card ID switch with which users can recognize the board by the ID via software when using two or more PIO-D24U cards in one computer. 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.
