The PIO-D168U card is the new generation product that ICP DAS provides to meet RoHS compliance requirement. The new PIO-D168U card is designed as a drop-in replacement for the PIO-D168, and users can replace the PIO-D168 by the PIO-D168U directly without software/driver modification.

The PIO-D168U universal PCI card supports 3.3 V/5 V PCI bus while the PIO-D168 supports 5 V PCI bus. These cards provide 168 TTL digital I/O lines, and these lines are grouped into eighteen 8-bit bi-direction ports. Every three ports on a connector are grouped and 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-D168U also adds a Card ID switch on-board. Users can set Card ID and then recognizes the board by the ID via software when using two or more PIO-D168U cards in one computer.

The PIO-D168/D168U supports various OS such as Linux, DOS, Windows 98/NT/2000 and 32-bit/64-bit Windows XP/2003/Vista/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.

  • DOS Lib and TC sample program (with source codes)
  • DLL and OCX SDK for Windows 95/98/NT/2K.
  • DLL and OCX SDK for 32-bit and 64-bit Windows XP/2003/2008/7/8/10.
