Card PCI Express 144 kênh vào/ra số DIO ICP DAS PEX-D144LS CR


  • Support PCI Express x1
  • 144 channels of digital I/O
  • Bi-direction programmable I/O ports under software control
  • Pull-high/Pull-low Jumpers for DI Ports
  • Card ID Function(SMD Switch)
  • Four Interrupt sources
  • Digital Output status readback


The PEX-D144LS supports PCI Express bus. These cards provide 144 TTL digital I/O lines that are grouped into eighteen 8-bit bi-directional ports. Each group of three 8-bit ports is arranged on the connector as Port A (PA), Port B (PB) and Port C (PC), respectively, and all ports are configured as inputs Ports on power-up or after a reset.

The PEX-D144LS provides a high-density connector that reduces the amount of installation space required for the card in the computer. The PEX-D144LS cards include an onboard Card ID switch that enables the board to be recognized via software if two or more boards are installed in the same computer. The PEX-D144LS also adds pull-high/low jumpers allow the DI status to be predefined instead of remaining floating if the DI channels are disconnected or interrupted.

The cards support various OS versions, such as Linux, DOS, Windows. 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.
