You can use time as a trigger for sync pulses on delta-sigma C Series modules. To use a sync pulse with a time source, specify a specific time in NI-DAQmx. Refer to Timing and Triggering in the NI-DAQmx User Manual for more information on accessing time-based features in the NI-DAQmx API.

Note To accurately synchronize delta-sigma devices in two or more separate tasks, you must specify the same sync pulse. Otherwise, a sync pulse is initiated by software implicitly, even if time start triggers are specified for the tasks. However, for multichassis tasks, the sync pulses and start triggers are automatically synchronized.
