NI 9211 Error -200474

NI 9211 is crashing my code when I try to access the channel with daqmx analog read; channels should be configured correctly; am reading two thermocouple (ni9211) modules on a daqmx chassis. The analog voltage module is responding correctly (no errors).

I think I found the answer. The NI 9211 is incredibly slow (14S/s); I'm used to 250 kS/s). I was trying to take too many samples, and it was timing out.
