I am currently working with a system of 4 USB X series (NI USB-6356). I am using all 32 analog input channels for data acquisition. I need the data acquistion to be synchronized. I have a start trigger for my master DAQ, unfortunately it cannot be physically wired to all 4 of my devices (due to low supply current). Thus, I am looking for a software solution. I am hpoing there is a way to write the LabView programsuch that when master device receives the trigger, all devices start their read task. The attached picture is my program so far, I have about 300us delay.
Does anyone know if I can change the program to get the acquisition more synchronized?
Thank you,
Leslie
