This is expected behavior. The NI-DAQmx driver
drops support for our legacy SCXI hardware in all versions at and after NI-DAQmx 19.1
Therefore, to enable SCXI configuration within NI MAX or Calibration Executive, uninstall NI-DAQmx within NI Package Manager (NIPM) and reinstall NI-DAQmx 19.0
- Ensure the dependency NI-DAQmx Runtime with Configuration Support is properly uninstalled and reinstalled with a compatible version at or before 19.0. This is the component that enables the SCXI configuration.
