CompactDaq USB-based data-acquisition system

National Instruments, www.ni.com

You can use the CompactDaq mainframe to configure a USB data-acquisition system for the lab, the production floor, or the field. The mainframe accepts up to eight signal-conditioning modules for voltage, thermo-couple, and digital signals. Analog modules contain their own analog-to-digital converters. Modules range from an eight-channel digital I/O module to a four-channel, 50-ksamples/s digitizer for audio and vibration measurements.

Modules are hot-swappable, so you can reconfigure a system without powering down. The mainframe increases throughput for large data transfers though direct memory access (DMA) transfer between the data-acquisition and USB sections. Software support includes a datalogging application and programming interfaces for LabView, Visual Studio .NET, and C/C++.
