Issue Details

My cDAQ chassis cannot be detected under Pharlap RT after upgrading DAQmx driver to 19.0 and above. Why does it happen? 


According to the file about NI-DAQmx readme update, CompactDAQ chassis support on Phar Lap was discontinued entirely as of NI-DAQmx 19.0. So you need to use Linux RT to detect cDAQ chassis with DAQmx 19.0 or higher.
