Multichannels Synchronized AI AO start trigger shared external clock

[prinho]

I am developed a program after the sample program Sync AI AO.  I use encoder  Z index as start trigger and A signal as external clock to generate and acquired samples at the same time using DAC PCI 6733 and ADC PCI 6143.   I generate continuous signal and change it constantly. The Generation and Acquisition are synchronized for one channel. The problem arise when I use two channels. The PCI 6733 change the output but the PCI 6143 needs more cycles to take the updated output signal. I can upload the c code when is necessary.
