Selecting Trigger Lines in a Multi-Device DAQmx Task

Hi,

I have 4 PXIe-4303 cards in a PXIe-1095 chassis. I can add channels from all 4 cards to a single DAQmx Task and DAQmx will take care of the synchronization automatically (so called multiple device task or "Channel Expansion"). In general this works well. My problem is that the Task will occupy PXI_TRIG0 and I want to use PXI_TRIG0 for different purposes (there are additional modules in the chassis). 

There are plenty of free trigger lines left. How can I tell the task to use, for example, PXI_TRIG1 instead?

Thanks

Dirk
