The PCIe-DA16-16 series are x1 10.5” cards that can be installed in long PCIe slots. They contain sixteen or eight digital-to-analog converters (DACs), 24 bits of digital I/O, and three 16-bit counter/timers.

The DACs can be updated individually or simultaneously. The board features a variety of unipolar and bipolar voltage ranges or a 4-20 mA current range (sink) for each DAC giving the user a variety of options. To ensure that there will not be excessive outputs to external circuits when the board is powered on, automatic circuits limit analog outputs to zero volts until initialized via software command.

Each DIO line is buffered and capable of up to 32mA source/sink. The VCCIO logic level is globally configured via jumper selection as 5V or 3.3V. Also, ports A, B, CHi, and CLo are factory configured as pull-up (to the selected VCCIO) through 10k? resistor networks. These groups can be configured for pull-down as a factory option.

The card includes an emulated 82C54 counter/timer which has three 16-bit programmable down counters. These are configured as Event counters (See Block Diagram) and can also be used as a frequency source derived from an onboard 1 MHz clock. These counters can generate IRQs at a programmed frequency, and/or initiate DAC updates. This allows for very precise timing of waveform generation.

The DAC’s connections are made at a 37-pin D-subminiature Male connector on the card mounting bracket.

The digital I/O and the counter/timer signals connections are made through a 40-pin 0.1? IDC header and a ribbon cable to a second bracket that can install alongside the first.

SOFTWARE

The card is supported for use in most operating systems and includes a free Linux and Windows compatible software package. This package contains sample programs and source code in C#, 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. Embedded OS support includes the family of Windows Operating Systems including IoT. ACCES is also now offering a VxWorks driver/library for the ultimate real-time process monitoring and control solution.
