I am using an Eight Channel NI9421 in a CompactDAQ appplication. Does this module/chassis combination support the functionality of DAQmx ChangeDetectionTiming() and RegisterSignal Event() ? See code snippet attached.
OS: WindowsXP-SP3 Using LabWindows CVI V8.5 Running DAQmx9,3 on 2.93Ghz Dual Core with 2GRam
NI Hardware: CompactDAQ Chassis 9178 with various Modules including the NI 9421.

Hello,
The Labview example finder does list the 9421 as a device that supports change detection. I do not program often in CVI, but those calls are the C equivalent to the Labview functions. Attached is a Labview example for change detection with the 9421.
