Why do I See Error -200077 when I Attempt to Perform Correlated Digital I/O on Ports Beyond Port 0?

Hardware: Multifunction DAQ (MIO)>>M Series

Problem:
I have read that my particular M Series MIO DAQ board supports correlated (i.e. hardware-timed) DIO operations. Which ports on the device support this feature? Why do I see Error -200077 when I attempt to use a port besides port 0?

Solution:
Some M Series devices support correlated DIO on port 0. If you attempt to use hardware timing on a port other than port 0, you will receive NI-DAQmx Error:

Error -200077 occurred at an unidentified location.
Possible reason(s):
Measurements: Requested value is not a supported value for this property.


Currently, certain M Series devices offer either 8 or 32 lines of hardware-timed DIO. The product website for each M-series device has a bullet point specifying the number of correlated digital lines supported. These product pages are available by following the M Series Data Acquisition Boards link in the Related Links section.

Additional device-specific information is available in the M Series User Manual linked in the Related Links section.  Also note that correlated DIO is not supported with E Series devices.
