Description

Model DA-06A can be installed in I/O slots of PC/ XT/AT class computers. It economically provides six independent 12-bit Digital-to-Analog Converters (DAC) and 24 digital input/output channels. Each DAC has double-buffered input for single step update and occupies a unique address location. Analog Output Update Mode is selected by a selector switch on this card. Three update modes are available:

  • Individual update of each channel.
  • Simultaneous update of all selected channels.
  • Simultaneous update of all selected channels upon receipt of an external signal.

(Note: This mode requires use of six digital I/O lines on Port C.)

Digital I/O channels are provided from a type 8255 Programmable Peripheral Interface (PPI). The PPI has 24 I/O bits which may be programmed in three modes of operation:

  • Mode 0: Each group of 8 I/O bits may be setup to be input or output.
  • Mode 1: Each group may be setup to have eight lines of input or output. (Note: in this mode, three lines are used for handshaking and interrupt-control signals.)
  • Mode 2: Eight lines are used for bidirectional bus and five lines are used for handshaking.

Base address selection is via on-card DIP switches and the DA-06A requires 16 consecutive I/O address locations. The base address can be selected anywhere within the I/O address range of 000-3FF (hex) providing that the address locations do not overlap other functions. Data are written to the DAC’s in right-justified 2-byte binary format (8 LSB’s and 4 MSB’s). For example:

Unipolar Ranges:

0000 0000 0000 = Zero
1000 0000 0000 = ½ Scale
1111 1111 1111 = Full Scale

Bipolar Ranges:

0000 0000 0000 = Neg. Full Scale
1000 0000 0000 = Zero
1111 1111 1111 = Pos.FullScale

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.

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 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.
