Supporting wireless, USB and Ethernet buses, National Instruments’ NI cDAQ-9191, cDAQ-9181 and cDAQ-9171 chassis give engineers and scientists the portability of a data logger with the performance and flexibility of modular measurements. They are suitable for all NI C Series modules for the NI CompactDAQ platform and can be used in conjunction with the existing 4- and 8-slot chassis. The chassis operate in a temperature range of 0 to 55 °C and can withstand up to 30 g shock and 3 g vibration. More than 50 measurement-specific modules featuring multiple electrical and sensor connectivity options can be combined with any chassis to create customized systems specific to the needs of numerous applications. NI Signal Streaming technology delivers high-bandwidth capabilities for sustained high-speed and bidirectional data streams over USB, Ethernet and wireless buses. Zero configuration networking technology simplifies initial setup, eliminating the need for IT involvement in network setup and integration. Included with each chassis, the NI-DAQmx driver software delivers increased productivity and performance. It allows users to log data for simple experiments or develop a complete test system in NI LabVIEW, NI LabWindows™/CVI, ANSI C/C++ or Microsoft Visual Studio .NET. A consistent API means that an application developed for an NI CompactDAQ wireless chassis will work with an NI CompactDAQ USB or Ethernet chassis without any modifications to the software. In addition, the chassis support the CAN C Series module for optimal communication across various networks.
