Chapter 1 Getting Started with the cDAQ Chassis
• PFI Signals—The PFI signals provide access to advanced features such as triggering,
synchronization, and counter/timers. You can also enable a programmable debouncing
filter on each PFI signal that, when enabled, samples the input on each rising edge of a filter
clock. PFI signals are available through parallel digital input and output modules installed
in up to two chassis slots and through the two PFI terminals provided on the cDAQ-9188
chassis. Refer to the PFI section of Chapter 4, Digital Input/Output and PFI, for more
information.
• Flexible Counter/Timers—The cDAQ chassis includes four general-purpose 32-bit
counter/timers that can be used to count edges, measure pulse-widths, measure periods and
frequencies, and perform position measurements (encoding). In addition, the
counter/timers can generate pulses, pulse trains, and square waves with adjustable
frequencies. You can access the counter inputs and outputs using parallel digital modules
installed in up to two slots, or by using the two chassis PFI terminals provided on the
cDAQ-9188 chassis. Refer to Chapter 5, Counters, for more information.
