And how your program will come to know, whether it is acquiring or not???
Just check for that condition so that you should get a boolean (TRUE or FALSE) output, now wire the same to the LED indicator (with customized color).
Refer to the attached snippet.
Also you can't have 4 different LEDs for different channels, as all four channels are part of same TASK so, if there is data acquisition from one channel happening, it means data acquisition from other three channels is also happening at the same time.
