acquiring simultaneously from multiple DAQs
Posted: 07 May 2021, 17:06
I need to acquire data simultaneously from 2 different pieces of hardware: (1) a Blackrock NSP and (2) an EMG unit that plugs in to the host PC's USB. I need these two data streams to be synchronized so that hitting "start" on BCI2000 begins the data acquisition for both pieces of hardware. What is the best setup for achieving this? I can imagine streaming the data across a network connection by specifying the IP address in the batch file, but I have never used that approach. Does that setup combine the data into one single .dat file? I have also recently learned of the --AllowMultipleInstances command line option that can be passed at startup, but I haven't been able to get that working so far.
Whatever route ends up being chosen, if >1 data file is recorded then I need them to be synchronized (assuming sampling rates are kept the same for the 2 pieces of hardware).
Thanks.
