DAQmx: Multiple digital output tasks for the same card both using onboard clock

[joshxdr]

I have a PCI-6259 DAQ card that I am programming with DAQmx. I want to create two digital output tasks on the same card. One task uses onboard clock, continuous samples. The other task uses onboard clock, finite samples, and an external trigger with trigger property Start.Retriggerable=TRUE. Is this possible with my hardware and DAQmx? Will there be a conflict if two tasks use the same clock source?

This is not possible, you may only have one hardware-timed DO task per device.

Ok, I guess two hardware timed DO tasks is not possible. 

Is it possible to have a hardware timed AO/AI/DI task running at the same time as a hardware timed DO task? Can they use the same hardware source?

Or even two simultaneous hardware timed AO tasks (I am guessing this one is a no)?

Yes and Yes.

Your guess is correct, it is not possible to have two simultaneous hardware-timed AO tasks on a single device.
