The STB-68 screw terminal board allows you to break out signals from an I/O card to screw terminals for easy field signal wiring of relays, sensors, and switches commonly found in industrial environments. It features a latching 68 position high density pin in socket connector and can be used with any I/O product that has a compatible 68 pin mating connector. The STB-68 can be mounted using the provided 4/40 x ½ inch standoffs to a panel or plate. Additionally, the board can be mounted directly to the enclosure of the USB-AI and Fast USB-DIO Series of USB modules. With the purchase of the MP104-DIN accessory, the STB-68 can be mounted directly to a DIN-Rail. For OEMs using ACCES USB boards, the STB-68 can be mounted directly to the board itself using the provided standoffs. Two different mating cables are offered. Part number C68PS18L is an 18-inch shielded round wire type with molded backshells. Part number C68MM-1.75 is a 68 pin male to male SCSI ribbon cable, 1.75 inches long.

The universal nature of the STB-68 allows for analog and digital connectivity with a variety of ACCES products. Its compact and small (3.775″ X 3.550″), ideal for tight spaces. What makes the STB-68 screw terminal board unique is that its PCB size and pre-drilled mounting holes match the USB/104 and PC/104 form factors. This ensures a variety of easy and flexible installation and mounting options using standard standoffs.

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 XP -> 10, 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, and 2000.


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 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 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, 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 EWriter, a program that allows you to read and write data in the user-accessible EEPROM locations on all our USB data acquisitition 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.
