Dear community,
I have a question whether MCC USB-25xx boards (USB-2537 in particular) can synchronously and simultaneously input and output data vectors with "readwrite" command within MATLAB DAQ Toolbox? - In MATLAB Product Support document (https://files.digilent.com/manuals/MATLAB-hw.pdf) it's written "session-based (64-bit) interface support only. Analog output streaming is not supported". However, I'm not aware if "readwrite" command is "session-based" or "streaming".
Eventually, my task is to analyze the response of a circuit to the arbitrary waveform. Samples Data is provided and acquired in chunks of a few thousands.
Thanks for insights.

According to https://www.mathworks.com/hardware-support/measurement-computing.html
Note: The support package does not support counter/timer subsystems, digital I/O subsystems, triggered acquisition, specialized voltage measurements (thermocouple, etc.), or the use of Simulink data acquisition blocks for Measurement Computing DAQ hardware.Supported Hardware
The support package is tested to work with the following Measurement Computing DAQ devices for analog input and analog output operations:

So digital channels are not supported on MCC devices.

Walter,
Thank you for the response. I did read the quoted page. Probably I didn't explain my question properly.
Let's say, I defined ANALOG input and ANALOG output channels. There is an external circuit connected to those inputs and outputs. I need to generate a certain waveform from analog output(s) and get the circuit response waveform from analog input(s) for consequent analysis. Waveform generation and input waveform sampling must be conducted simultaneously.
So I'm asking whether MCC USB-25xx boards (USB-2537 in particular) can synchronously and simultaneously input and output ANALOG data vectors with "readwrite" command (or other means) within MATLAB DAQ Toolbox?
