PEX-D144LS – PCI Express, 144–channel Digital I/O Boards

New Products 2014-12-26

Introduction

The new PEX-D144LS supports PCI Express bus and is designed as an easy replacement for the PIO-D144U/D144LU series board, without requiring any modification to the software or the driver.

The PEX-D144LS provides a 100-pin SCSI II high-density connector and a 50-pin box header that reduces the installation space required for the card in the computer and has 144 digital I/O lines( eighteen 8-bit bi-direction ports). All ports are configured as inputs when power-up or reset.

The PEX-D144LS also adds a Card ID switch and pull-high/low resisters for DI on board. Users may set Card ID on a board so the board can be distinguished by the ID via software when using two or more PEX-D144LS cards in one computer. The pull-high/ pull-low resisters specify the DI status; when the DI channels are unconnected, the DI status will remain in high or low status without being left floating.

This card support various OS such as Linux, DOS, Windows 98, Windows NT, Windows 2000, 32-/64-bit Windows XP/2003/2008/Vista/7 and Windows 8. 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.
