The PIO-D64U card is the new generation product that ICP DAS provides to meet RoHS compliance requirement. The new PIO-D64U card is designed as a drop-in replacement for the PIO-D64, and users can replace the PIO-D64 by the PIO-D64U directly without software/driver modification.

The PIO-D64U universal PCI card supports 3.3 V/5 V PCI bus while the PIO-D64 supports 5 V PCI bus. These cards provide 32-ch digital input and 32-ch digital output that consist of two 16-bit input ports and two 16-bit output ports. The PIO-D64U and PIO-D64 also offer 6-ch counter/timer with four-clock sources, 2 MHz, 1 MHz, 500 kHz and 250 kHz. The user can use the clock source from the soldering pad. 3 of the 6-ch timer/ counter are for general purposes such as frequency measurement, event counting and pulse generation; the other 3 channels are for interrupt function.

The PIO-D64U also adds a Card ID switch and pull-high/ pull-low resisters for DI on-board. Users can set Card ID and recognize the board by the ID via software when using two or more PIO-D64U 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 may remain in high or low status other than floating.

The PIO-D64/D64U supports various OS such as Linux, DOS, Windows 98/NT/2000 and Windows 32-bit Windows XP/2003/Vista/7. It also provides the DLL and Active X control, and various language sample program 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.
