CompactDAQ Chassis control the timing, synchronization, and data transfer between C Series I/O modules and an external host. The chassis features USB or Ethernet connectivity and are available in different slot counts for the right amount of I/O.
NI offers multiple models of chassis. However, only the cDAQ-9183, cDAQ-9185, cDAQ-9187, cDAQ-9189, and the cDAQ-9188XT are compatible with the watchdog functionality.
