PXIe-6368 Trigger signal question.

Hi!

I am using PXle-6358 daq.

This daq is installed in PXle-1073 and two SCB-68A are used for simultaneous multi-channel measurement.

I try to collect data by receiving a trigger signal on this daq.

I am using the DAQ-USB-6251, which is used by connecting the trigger input signal to APFI 0 (pin 29) and the GND signal to AI GND (pin 30).

I wonder which pin on the SCB-68A should connect the PXle-6358 daq trigger input signal and where to connect the GND signal.
