When our engineers go on the road to troubleshoot structural component failures or machine vibration problems, they grab their laptop with iTestSystem installed and Pelican case containing an NI CompactDAQ (cDAQ) chassis and an assortment of C-Series modules, accelerometers, and strain gauges. The cDAQ chassis that they typically use is a cDAQ-9189 ethernet chassis.
The cDAQ-9189 is an extended temperature TSN enabled 8-Slot Ethernet chassis designed for distributed sensor measurement systems. The chassis controls the timing, synchronization, and data transfer between C Series I/O modules and your laptop. Since the chassis has an integrated network switch and is TSN enabled, measurements from multiple chassis are synchronized by simply daisy-chaining chassis with an ethernet cable.
