Synchronizing DSA or S Series Devices With a Single NI-DAQmx TaskPrimary Software: LabVIEW Development SystemsPrimary Software Version: N/A Primary Software Fixed Version: N/A Secondary Software: Driver Software>>NI-DAQmx Hardware: Modular Instruments>>Dynamic Signal Acquisition and Analysis (DSA)
Problem: I'm using several dynamic signal acqusition (DSA) cards in the same chassis and need all of the these cards to be synchonized. What is the easiest and most efficient way to accomplish this? Does this method also work for simultaneous sampling S Series cards? Solution: Multidevice task support for DSA devices began with NI-DAQmx 8.0 and for S Series MIO devices beginning with NI-DAQmx 8.1. The multidevice task, also known as channel expansion, provides a very easy and efficient way to synchronize the acqusition of multiple devices of the same type since the NI-DAQmx driver handles all of the signal routing for you. The nessesary triggers and clocks are intelligently chosen and automatically routed. For the user, it consists of simply adding multiple devices, separated by a comma, to the same task.
