Sync multiplexer and DAQ operation

HI all.

 

Currently Im using a 2530 PXI multiplexer in a octal 16x1 topology and an 8 channel 6466 PXI Daq,

 

I have a repeating waveform at 5Hz and i require to conduct the swich operation at the end of each period to change what the AI is measuring.

 

The Daq is set up as a continuous regeneration of the waveform to output from the AO and also reads the data on the 8 AI channels.

 

I have tried sending a software trigger to the multiplexer (using NI-Switch) but, although this occurs at 5Hz, the switch happens ~200ms into the waveform period.  This is in the same loop as the DAQmx read vi

 

How can i configure this to switch at the end of the period?

Hi Gorgy,

 

Are you able to post your code so I can look at it? Have you tried hardware triggering the multiplexer? 

 

 

Regards,
