In StockDescription
The PCI-DIO-48JP/JPS, and PCI-DIO-48JPL/JPLS are 48-bit parallel digital input/output cards designed for use in PCI-Bus computers. The card is 6.9 inches (175 mm) long and may be installed in any 5-volt PCI slot in IBM and compatible computers.
The 48JP/48JPS cards use a 68-pin SCSI-type connector which is pin-in-socket, and has jack-screws provided as a means to retain the mating cable.
The 48JPL/48JPLS cards use the 68-pin SCSI-type pin-in-socket connectors; however one-touch latches are used instead of jack screws.
For solutions which don’t require a 68 pin SCSI type connector, please consider our PCI-DIO-48S product family which uses 50-pin headers.
The cards contain two Programmable Peripheral Interface chips type 8255-5 (PPI) to provide computer interface to the 48 I/O lines. Each PPI provides three 8-bit ports A, B and C. Each 8-bit port can be software configured to function as either inputs or latched outputs. Port C can also be configured with four inputs and four output latches.
Each I/O line is buffered and capable of sourcing 15 mA or sinking 24 mA (64 mA on request). Tristate I/O line buffers are configured automatically by the hardware logic for input or output use according to a direction control signal from the control register in the PPI. Pull-ups on the card assure that there are no erroneous outputs at power up until the card is initialized by system software.
These cards use one address space, and occupy 16 consecutive register locations. 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 card’s base address, you can only determine what the system has assigned. The PCI Bus supports 64K of I/O address space so your card’s address may be located anywhere in the 0000 to FFFF range.
INTERRUPTS
The distinguishing feature for the “48S” model is that the state of all inputs can be monitored and if one or more of the bits change states, a latched interrupt request can be generated. Therefore it is not necessary to use software polling on the inputs to detect a change of state condition. The change-of-state interrupt is enabled by a software write command to an interrupt-enable register. Once latched, the change-of-state interrupt can be cleared by a software write.
The C3 bit on either 24-bit port can be used as an external interrupt to the computer if interrupt enable (IEN) jumpers are installed. When C3 is level triggered, an interrupt is requested. Interrupts from the two ports are OR’ed together with any change-of-state interrupt. The interrupts are assigned by the system.

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 7 -> 11, both 32 & 64 bit, including “Server 2008,” “Embedded,” and “Compact” flavors 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, 2000, and XP.
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#, and Delphi, with many devices including samples in Visual Basic (5 and .NET), Visual C/C++, and 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 7 -> 11 — all in both 32-bit and 64-bit flavors, and including consumer, server, and embedded varieties — as well as the 2.6 and newer Linux kernels and recent OSX / macOS versions. Many products continue to ship with driver support for Windows 95, 98, Me, NT4, Windows 2000, XP, and more, but support for these operating systems is considered deprecated.
Setup Programs and Utilities
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 EWriter, a program that allows you to read and write data in the user-accessible EEPROM locations on all our USB data acquisition products; or 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.
