Can I Use the Hardware Clock of My USB-6211 for Digital I/O?

Updated Jun 13, 2019

Issue Details

  • My digital input task is running slow due to using software timing.
  • In the specifications sheet of the USB-6211 I see that there are three internal base clocks on the device.
  • I'm unable to use these clocks for digital input and output tasks.


These internal clocks (80 MHz, 20 MHz and 0,1 MHz) are only accessible for analog I/O. The only timing configuration available for digital I/O on this device is software timing.

Additional Information

If you require hardware timing for Digital I/O the closet pick is the NI USB-6341 module.
