9188 with 8 modules. I am seeing a long trigger delay

[aeastet]

I am seeing a trigger delay with the set up that I have.

cDaq 9188XT

9229 slot 1

9229 slot 2

9229 slot 3

9237 slot 4

9237 slot 5

9474 slot 6

9375 slot 7

9213 slot 8

I am using the high speed digital output to trigger multi high speed timed events. I am using channel 7 on the 9474 module to the PFI0 on the chassis to trigger the Analog data acquisition. This should happen at the smae time as the ch 7 trigger. When I get the data I see the actual trigger at around 4300 samles vs the 300 where I would expect it to be.

Channel setup is 10KHtz

5000 Sample

300 Pre trig sample

Any thoughts or ideas would be appreciated.

I tried to attach the code but it kept telling me that my zip file wasn't a zip file and deleating it.

Here is the analog trigger vi

Any help would be appreciated.

Hi YanFeng,

Just curious but have you tried to trigger the Analog data acquisition outside this application? This will help identify if it is code related or hardware related. This link may help: http://www.ni.com/tutorial/4329/en/

Post back with your results.
