USB-6009 as pulse geneartor

[U_of_A]

Hello,

I am using a USB-6009 DAQ card to read signal from 3 channels. at the same time I want to read a TTL trigger and genearte a TTL trigger or a square waveform with 4 sec delay. 

I am trying to read the trigger and then write it out with "wait" function in my loop. but I find there is a bug with writing the array out. I can read the write the trigger with single channel but not with multiple channel.

here are the VIs. please help me out with the multiple channel file to see why it doesn't work.
