The PIO-D24U/D56U card is the new generation product that ICP DAS provides to meet RoHS compliance requirement and the new PIO-D24U/D56U card is designed as completely compatible for the PIO-D24/D56.
The PIO-D24U/D56U supports 3.3 V/5 V PCI Bus; the PIO-D24/D56 supports 5 V PCI Bus. The PIO-D24/D56/D24U/D56U 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. In additional, the PIO-D56/D56U provides the 16-bit digital inputs and 16-bit digital outputs.
The PIO-D24U/D56U also improves 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 in software when using two or more PIO-D24U/56U cards in one computer. The pull-high/ pull-low resisters can determine the DI status; when the DI channels are unconnected, the DI status will hold in high or low status other than floating.
The PIO-D24/D56/D24U/D56U supports the OS that include Linux, DOS, Windows 98, Windows 2000, Windows NT, Windows XP 32-Bit, Vista 32-Bit and Windows 7 32-bit. It also provides the DLL and Active X control to help user who implement the product. This sample program have Turbo C++, Borland c++, Microsoft C++, Visual C++, Borland Delphi, Borland C++ Builder, Visual Basic, C#.NET, Visual Basic.NET and LabView to help user more fast to compose.
