National Instruments cDAQ-9188 data acquisition system

An ethernet-based NI CompactDAQ modular data acquisition system combines the ease of use and low cost of a data logger with the performance and flexibility of modular instrumentation.

The cDAQ-9188 chassis is designed to hold eight I/O modules for measuring up to 256 channels of electrical, physical, mechanical or acoustic signals in a small (25 x 9 x 9 cm), rugged form factor.

With more than 50 different I/O modules to choose from, engineers and scientists can build remote or distributed, high-speed measurement systems using standard gigabit ethernet infrastructure.

In addition, the chassis simplifies initial set-up with zero configuration networking technology and a built-in, web-based configuration and monitoring utility.

It uses signal streaming to deliver high-bandwidth data over ethernet to a host computer and provides the ability to maintain bidirectional analog and digital waveforms continuously over a TCP/IP connection.

With NI-STC3 timing and synchronisation, each chassis can also manage up to seven separate hardware-timed I/O tasks at different sample rates, including analog I/O, digital I/O and counter/timer operations.

In addition to the ethernet chassis, the platform includes a 4- and an 8-slot USB chassis and C series I/O modules. More than 50 C series modules are available to use interchangeably in CompactDAQ systems, each of which is hot-swappable and auto-detectable for simplified set-up.

The modules offer integrated signal conditioning and multiple connectivity options to create custom, mixed-measurement systems specific to the needs of an application.

Driver software, which is included, allows engineers and scientists to log data for simple experiments or develop a complete test system in LabVIEW, LabWindows/CVI, ANSI C/C++ or Visual Studio .NET.

Programming with LabVIEW delivers the most performance for the least effort. LabVIEW graphical programming makes it possible for engineers and scientists to develop measurement, test and control systems using intuitive graphical icons and wires that resemble a flowchart.
