The NI-Sync driver provides limited support for the NI PXI-6683(H) timing & synchronization modules when used in a PXI system running LabVIEW Real-Time. The availability of features depends on whether your PXI controller is running Pharlap ETS or NI LinuxRT.
Note: NI will remove support for Phar Lap for cRIO in the NI 2020 Software Release and for PXI in the NI 2022 Software Release. For more information, please see the Phar Lap RT OS EOL Road Map.
