Multiple device data acquisition for NI 9211

[JSlane]

    I am using three NI 9211 thermocouple modules with 12 thermocouples.  I want to synchronize all 12 measurements and write to a TDMS file.  The example vi I'm looking at is called cdaq_module_synchronization.vi in the NI Developer Zone, article NI-DAQmx:  NI CompactDAQ Module Synchronization.  Do the three modules have to be in the cDAQ-9172 chassis for it to work?

Hello JSlane,

The NI-9211 thermocouple input module can be used with either the CompactDAQ or CompactRIO chassis.  However, the example VI that you are looking at uses DAQmx functions, which means that you must use the NI-9211s in the CompactDAQ chassis, as NI-DAQmx is the device driver for the CompactDAQ chassis, whereas NI-RIO is the device driver for the CompactRIO chassis.

Best wishes,
