  • Change-of-State (COS) detection IRQ generation
  • 10k ohm pull-up resistors
  • Four and eight bit ports independently software selectable for use as inputs or outputs
  • All signals brought out to optional panel-mountable 37-pin male D-Sub connector

  • TTL signaling with user supplied VCCIO (5V)

The mPCIe-DIO-24S is a type F1 PCI Express Mini Card (mPCIe) and optional cable assembly (D-Sub 37-pin Male connector) designed to be easily panel-mounted in any application environment. It uses the high speed PCI Express bus to transfer digital data to and from the card. The digital I/O is compatible with 8255 PPI chips making it easy to program. This also allows for simple and trouble-free migration from other ACCES PCI and PCI Express digital I/O cards, but also provides for advanced features enabled by the onboard FPGA logic.

The card provides three 8-bit I/O ports designated A, B and C. Port C can be further divided into two 4-bit nybbles. Each port can be programmed as inputs or outputs. Change of State (COS) detection and interrupt capabilities are designed to relieve software from polling routines that can consume valuable processing time. Each port can be programmed for detecting state changes on their lines, in which any changes of the enabled port's bits (low-to-high or high-to-low) will generate an IRQ. An ISR (interrupt service routine) then determines which bit changed state and clears the interrupt.

Applications

The mPCIe-DIO-24S is excellent for use in applications sensing inputs such as switch closures, TTL, LVTTL, CMOS logic and controlling external relays, driving indicator lights, and more. The mPCIe-DIO-24S can be used in the following markets.

  • Process Monitoring
  • Manufacturing/Production Test
  • Machine Control
  • Monitoring and Control
  • Security Systems, Energy Management
  • Industrial Automation
  • Factory Automation
  • Laboratory Automation
  • Embedded OEM

Special Order

Please contact ACCES with your precise requirement. Examples of special orders would be pull-down resistors, conformal coating, a TTL version with user supplied 5VDC VCCIO, custom software or product labeling, and more. We will work with you to provide exactly what is required.

Accessories and Connections

Available accessories include a 40-pin to male DB-37 cable and screw terminal boards for quick and easy connectivity. I/O on the card is accessed via a 40-pin latching Molex connector. Alternately, custom hardware cables and/or interfaces can be produced to fit your specific application requirement.

SOFTWARE

The card is supported for use in most operating systems and includes a free DOS, Linux , and Windows 2000/XP/2003/Vista/7/8/10 compatible software package. This package contains sample programs and source code in Visual Basic, Delphi, and Visual C++ for Windows. Also provided is a graphical setup program in Windows. Linux support includes installation files and basic samples for programming from user level via an open source kernel driver. Third party support includes a Windows standard DLL interface usable from the most popular application programs, and includes LabVIEW 8.5+ VIs. Embedded OS support includes Windows XPe, WES7, WES8, etc. Full register-level documentation of all features ensures easy compatibility in any application environment.
