USB Data Acquisition

Modules connect to a PC USB port using a standard, low-cost cable. When plugged in, the PC automatically identifies the module and installs device driver software, simplifying setup and reducing start-up time. Modules obtain all required power from the USB port, so no external power connection is ever required. Data collection is simple with our user-friendly Windows� software.

Model KUSB-3108 and Model KUSB-3116 modules feature 16-bit resolution with sample speeds of 50kS/sec and 500kS/sec, respectively. These multi-function modules offer from 8 to 16 analog input channels, up to four analog output channels, 16 to 33 digital I/O lines, and up to five counter/timer inputs. Model UD128A8D provides the hardware and software needed for a complete data acquisition system with minimal external circuitry. The USB plug-n-play interface makes it easy to configure. Model OM-CP-UltraShock 101-50-EB battery-powered, three-axis shock recorder measures and records temperature, pressure and humidity while shock is recorded at the peak acceleration levels. It records up to 170,000 measurements per channel, more than 1 million measurements total.

Model USB-1608HS-2AO has 2 additional channels of 16-bit analog output with range of -10 to +10 V. Both use separate A/D converter for each channel and each can acquire data in software paced or continuous scan mode.

Additionally, with the plug-and-play connectivity of USB, engineers and scientists have an easy-to-use, portable solution for their measurement, monitoring and control applications. Advertising can be a big profit eater for many business(es). Sometimes it can become a total loss. Adding simple PC graphical user interfaces (GUI) that can communicate with my embedded designs has put the finishing touches on them. By adding a nice PC GUI that can communicate with the embedded system over a serial port, you can perform things like system setup, real-time diagnostics, and tests.

Advantech’s proprietary lockable cable design secures the slave-module connections, preventing the cable from being unplugged accidentally. The hub is designed to be suitable for DIN-rail mounting.

Software for handling the data also becomes simpler to implement. The host system USB drivers separate data streams into logical channels called “pipes”. Software timing provides update rates up to 50 hz for all parameters, while hardware timing enables analogue/digital input rates up to 1200 hz [continuous] or 8192 hz [burst]. Most connections are accessed using built-in screw terminals, eliminating the need for costly connection blocks.

Applications that can now benefit from the higher accuracy include scientific instrumentation such as geological monitoring, materials analysis, environmental sensing, calorimetry, optics, spectroscopy, structural sensing and gas detection, along with medical device instrumentation such as heart rate monitoring. USB-628x devices are also ideal for electronics characterisation and research.
