NIDAQ_OUT

The NIDAQ_OUT (NIDAQMX) node is a consumer that writes an analog stream from Thalamus out to a National Instruments DAQ. It is the counterpart to the NIDAQ input node and is commonly used to drive external hardware – for example writing computed gaze coordinates out as voltages, or generating stimulation waveforms.

Properties

• Source: The node whose data is written to the DAQ.

• Channel: A list of DAQ output channels (and channel ranges) to write to.

• Digital: Write to digital output lines instead of analog output channels.

• Running: Begin writing to the DAQ.

The output sample rate follows from the source node’s data; the timing parameters (Sample Rate, Poll Interval, Channel Type) configured on the NIDAQ input node do not apply here.
