features and benefits
The PIO-D48U supports 3.3 V/5 V PCI bus.
These cards provide 48 TTL digital I/O lines, and these lines are grouped into six 8-bit bi-direction ports.
Every three 8-bit ports are grouped as port A (PA), port B (PB) and port C (PC) on a connector, and the port C can be split into 2 nibble-wide(4-bit) parts.
All ports are configured as inputs upon power-up or reset. The PIO-D48U also adds a Card ID switch and pull-high/ pull-low resisters for DI on board.
Users can set Card ID on a board and recognize the board by the ID via software when using two or more PIO-D48U cards in one computer.
The pull-high/ pull-low resisters allow the DI status to be specified when the DI channels are unconnected; the DI status will remain in high or low status other than floating. 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.
