myDAQ Synchronization

[Ya123]

Hello All! 
At this moment I am trying to use myDAQ system in project for collection analog signal from board of pressure sensors. 
The algoritm of measurements consist of two steps: 
1. Choosing sensor by sending 4 bit address on DIO port of myDAQ.
2. Analog signal acquiring from AI0 line by myDAQ. 
Now I am using stacked sequence diagram to make digital writing and then analog input reading. But this variant doesn’t work stable because of some jitter. 
Ideally, I want to setup myDAQ for starting Analog input immediately after DO write operation. 
Did anybody work with myDAQ and have ideas how to make synchronization between digital output and analog input? 

Thank everybody in advance, Evgeniy.

Hi Ya123,

I will see if I can find some resources to link to you that might be of assistance...

Ya123,

Glance over this forum post and see if the suggested method works for you. I am not sure what device you have but in the article is mentioned some devices where this is not possible due to the lack of hardware timing / triggering on the analog functions.
