NI DAQ settings

NI

  • device_ID must be set to the name of the DAQ you will use to run Zapit. Open NI MAX and find the name of your DAQ. Likely it will be called Dev1, Dev2 or similar. If you wish, you can change the name to something more meaningful, such as "zapit". Either way, find the name and enter this as the value of device_ID.

  • wrapper determines the method used by MATLAB to communicate with NI DAQmx. It can stay as dotnet but if you forgot to install DAQmx with .NET support enabled then you can set this to vidrio to get up and running. dotnet is recommended, though, as vidrio will produce a load of warning messages at the command line when running experiments. Furthermore there may in the longer term be features that require dotnet.

  • samplesPerSecond It's probably a bad idea to edit this.

  • triggerChannel defines the channel on which Zapit looks for a trigger before initiating stimulation during an experiment.
