The PCI-DIO-120, PCI-DIO-96 and PCI-DIO-72 are parallel digital input/output cards designed for use in PCI-Bus computers. The same printed circuit board is used for all three models and is populated for 120 bits, 96 bits and 72 bits respectively. The card is 12.2 inches (310 mm) long and may be installed in any 5-volt PCI slot in IBM and compatible computers.

The cards are designed for industrial applications and should be installed in a long PCI slot of an IBM or compatible computer. Each I/O line is buffered and capable of sourcing 15 mA or sinking 24 mA (64 mA on request). The card contains Programmable Peripheral Interface chips type 8255-5 (PPI) to provide computer interface to the digital I/O lines. Each PPI supports three 8-bit groups A, B, and C. Each 8-bit group can be configured to function as either inputs or latched outputs. Group C can also be configured as four inputs and four output latches. The I/O line buffers are configured automatically by hardware logic for input or output use according to the PPI control register direction software assignment.

Outputs of the I/O buffers are pulled up through 10K resistors to +5VDC. Outputs can be changed to pull down by jumper selection on the card. This pull-up/pull-down arrangement assures that there are no erroneous outputs at power-up until the card is initialized by system software. The I/O buffers may be tristated under program control.

Two I/O Lines of each port can be used to interface User Interrupts to the computer. Interrupts of all ports (one per port) are OR'ed together and the Interrupt level is assigned by the system. I/O wiring connections are via 50-pin headers on the board. Every second conductor of the flat cables is grounded to minimize the effect of crosstalk between signals.

The cards occupy up to 32 registers within the PCI address space. When the card is first installed, Windows will detect it as new hardware and assign it an IRQ number and base address. There are no switches to set or base addresses to assign, making it easy to use. You cannot set or change the cardís base address, you can only determine what the system has assigned. The PCI Bus supports 64K of I/O address space so your cardís address may be located anywhere in the 0000 to FFFF range.

Information about our Free Software packages:

ACCES is proud to provide a full suite of software support with every Data Acquisition product. We are committed to supporting the most popular operating systems and platforms for our customers. Currently we are actively supporting Windows XP through Windows 10, including "Server 2008," "Embedded," and "Compact" flavors in both 32-bit and 64-bit for all plug-and-play products including PCI, PCI Express, USB, and more. Many products continue to ship with support for additional operating systems such as DOS, Windows 95, 98, Me, NT4, and 2000.

Samples

Among the software we deliver with our products are sample programs in a wide variety of programming languages. These samples are used to demonstrate the software interfaces to our products — and many can be used as-is in your production environments, or to test functionality of the devices out-of-the-box. We're currently actively supporting sample programs in Microsoft Visual C#, Visual Basic, Delphi, and Visual C/C++, with many devices including samples in Borland C/C++ 3.1 for DOS. Additionally we provide National Instruments LabVIEW compatible DLLs and many demonstration VIs for our devices.

Drivers

Drivers for various operating systems are also provided, including active support for Windows XP -> 10 — all in both 32-bit and 64-bit flavors, and including consumer, server, and embedded varieties — as well as the 3.x and 2.6 Linux kernels and recent OSX versions. Many products continue to ship with driver support for Windows 95, 98, Me, NT4, and Windows 2000, but support for these operating systems is considered deprecated.

Setup Programs and Utilites

Our Data Acquisition devices also include a graphical setup utility that walks you through the process of configuring any option jumpers or switches on the device, as well as explaining a little about the various connectors present.

Many devices also include utility programs - little tools to make your use of the device easier, such as WinRISC, a "Really Incredibly Simple Communications" terminal program that lets you get started instantly with serial devices.

"Register Level" Documentation

Besides all this software in all these languages and operating systems ACCES has a policy of open and transparent development: none of our lowest-level "register" interfaces are hidden from you — we document every register in every bus card, every command in every serial board, and every usb control transfer in every USB Data Acquisition board. These lowest-level interfaces allow you to develop for our products in ANY operating system or language, regardless of our actively supporting it or having a driver for it. We have customers actively developing in ADA, Android, Python, Java, MATLAB, Solaris, and more, just by referring to our complete low-level interface documentation! And we provide the full source code to all of our drivers, regardless of operating system, to give you an even bigger head start in your own development tasks.

No Fees or Royalties

All of this software is provided at no additional charge, and is licensed under any of a variety of flexible — and royalty free — options. Check out our software license explanation if you'd like more information..


Custom Software

ACCES also offers Custom Software Services for our products. Our prices are unbelievably low, often as inexpensive as free! If you need something tweaked to support your needs, or an entire enterprise application developed from scratch, it is definitely worth your time to inquire with us, first.
