Multifunction Data Acquisition with UniDAQ

The UniDAQ system is a versatile data acquisition and processing system, optimized for higher channel count applications. It combines analog interfaces, signal processing, memories, safety features, power supplies and communication ports on a compact, easy to integrate board.

UniaDAQ multi-function data acquisition board level system

What makes UniDAQ stand out from the multitude of data acquisition boards available on the market is the combination of:

  • A high performance floating point DSP for local data processing, enabling completely self-contained operation or relieving a host computer from   real-time tasks
  • Phase-correct simultaneous sampling of all input channels
  • An expansion port providing interfaces for a variety of applications, such as mass storage for data logging, industrial real-time network controllers, GPIO, FPGA, display and touch screen for handheld devices and more
  • Manifold mounting options from rack-mount systems to handheld devices
  • Isolation barrier between analog and digital domain for robustness
  • Two communication ports: USB and Ethernet
  • USB firmware for in-site updates and diagnosis

UniDAQ Capabilities

Analog Inputs & Outputs

UniDAQ boards are available with high-resolution data converters for acoustic and vibration measurements, and with low-latency SAR (successive approximation) converters for control loops. Both systems use simultaneous sampling and provide excellent static and dynamic signal resolution.

Signal Processing

A floating-point DSP (digital signal processor) is used to scale and filter the input signals, equalize non-linear sensor characteristics, and provides ample processing power for complex control algorithms. Optional ARM+DSP processor variants are available to conveniently handle user-interfaces and web frontends without sacrificing signal processing real-time constraints.

Trigger Options

UniDAQ provides multiple configurable internal and external trigger options for the ADCs and DACs: hardware inputs, software-generated events, and synchronization signals from real-time networks.

Expansion Port

The Expansion Port lets you add mass storage devices like SD-card or eMMC for data and event logging, a user interface consisting of an LCD display, touchscreen and keypad, or GPIO ports.

A parallel bus interface and a high-speed SPI port are available to connect external controllers or an FPGA for encoder interfaces (EnDAT, BiSS), PWM outputs, and real-time fieldbuses (EtherCAT, ProfiNet, CAN) for production environment integration.

Software Compatibility

UniDAQ supports the integration of simulation tools and engineering software like Matlab/Simulink® and LabView® with NI-Visa USB RAW and Modbus-TCP data transfers. Besides signal analysis, stimuli generation and modelling, this also enables an efficient development of stand-alone applications: algorithms can be evaluated, ported to the DSP, and verified step-by-step.

The extensive support software contains sample configurations and demonstration programs for a variety of application areas. It is fully integrated into Texas Instrument’s Code Composer Studio development environment. The board firmware also includes ready-to-use functions for in-the-field software updates and diagnosis via a USB connection, optionally via Ethernet.

System Integration

Electrical isolation of the analog and digital circuits, combined with robust overvoltage-protected inputs and outputs, simplifies system integration and guarantees signal integrity and reliability even in harsh industrial environments.

Please refer to the data sheet and application notes for mounting options and integration examples.

Signal Conditioning

The analog inputs and outputs of the UniDAQ system serve the common industry standards. For applications with deviating requirements, we are happy to support you during development or supply ready-to-use front-end extensions to meet your specific requirements.
