1‑Slot, Ethernet and 802.11 Wi‑Fi CompactDAQ Chassis —The cDAQ‑9191 is a Wi‑Fi chassis designed for small, remote, or distributed sensor measurement systems. The chassis controls the timing, synchronization, and data transfer between C Series I/O modules and an external host. You can use this chassis with a combination of modules to create a mix of analog I/O, digital I/O, and counter/timer measurements. You can send data from the cDAQ‑9191 to a host PC over Ethernet or IEEE 802.11 Wi‑Fi. The chassis also has four 32‑bit general‑purpose counters/timers built in. You can access these counters through an installed, hardware‑timed digital C Series module for applications that involve quadrature encoders, PWM, event counting, pulse train generation, and period or frequency measurement.
