The PIO-D48U/PEX-D48 is the new generation product that ICP DAS provides to meet RoHS compliance requirement and is designed as completely compatible with the PIO-D48. Users can replace the PIO-D48 by the PIO-D48U/PEX-D48 directly without software/driver modification.
The PIO-D48U supports 3.3 V/5 V PCI bus, while the PEX-D48 supports PCI Express 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/PEX-D48 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/PEX-D48 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 PIO-D48/D48U and PEX-D48 supports various OS such as Linux, DOS, Windows 98, Windows 2000, Windows NT, Windows XP 32-Bit, Vista 32-Bit and 32-bit Windows 7. It also provides the DLL and Active X control, and various language sample programs in Turbo C++, Borland c++, Microsoft C++, Visual C++, Borland Delphi, Borland C++ Builder, Visual Basic, C#.NET, Visual Basic.NET and LabVIEW to help users to quickly and easily develop their applications.
