Slow loop with DAQmx read

[JPunltd]

Hello,

I am trying to read 8 channels at once using the NI9213 and DAQmx (see image attached). With this setup, the loop takes ~500ms each iteration. What can I do to improve this?

Thanks,

JP

You have not coded any timing so it's running at default speeds.  Look at the DAQmx examples like Thermocouple - Continuous Input.vi.  Your module even has a high speed mode you can use for really fast acquisition.  Read the manual.

BTW, NOT connecting your error wires WILL byte you in the butt eventually.  Always connect them so you can monitor errors while debugging.
