How to find the source name in the analog trigger?

[afai2003]

This is the labview code I use.

And I found trouble to get the source name.

No matter what I type.

It shows "Error -200265 occurred at DAQmx Start Task.vi:1"

What does actually happen??

hi

if you refer to the context help of the DAQmx trigger vi, it tells you in detail what the source name should be. even the error message you got explains the same. refer to the error help for the error code you see.

the physical channel you are acquiring, should have a name configured in the first step. use the same name as the source name. if you are acquiring only one signal and using the same for anolog trigger, then do as mentioned.

if you have more than one channel beign acquired, then give unique names to each channel and then wire the name of the trigger channel to the source.

refer to NI examples to see how the triggers are configured
