Description
The PEX-D24 provides 24 TTL digital I/O lines, consisting of three 8-bit bi-direction ports. The 8-bit ports are named port A (PA), port B (PB), port C (PC) with all ports being configured as inputs upon power-up or reset.
The PEX-D24 has one D-Sub connector and supports PCI Express x1 bus.
The PEX-D24/D56 has a Card ID switch with which users can recognize the board by the ID via software when using two or more PIO-D24U/56U and PEX-D24/D56 cards in one computer.
These cards support various OS versions, such as Linux, DOS, Windows 98/NT/2000 and 32/64-bit Windows 7/Vista/XP. 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.
