I have a 9189 cDAQ chassis and several NI 9231 cDAQ modules.
How many AI tasks with different sample rates can I have.
Thanks.

Thanks. That's what I remembered, but I just cannot find anything reference to this from ni.com.

Its down deep in a cDAQ whitepaper

Hello Ian,
In this case you can actually only run 2 hardware timed analog input tasks with different sample rates because the 9231 is a DSA module. This is because the cDAQ 9189 is a Gen II chassis and Gen II chassis support a maximum of 2 synchronization pulses. This is called out here.
