ni Scope multi-recording acquision failure (NI TClk)

[EdwardWU]

Hi, everyone. I am quite new to NI TClk function, and my hardware is a NI PXIe-8880 embedded controller with one PXIe-5122 and three PXIe-5413. 

What I wanna do is to generate 180 phase shift from two AWG to a simple system and detect the time-domain signal by digitizer. So there is a on-line digitizer setting during the experiment for continuous and multi-recording. Attached with the code. 

While there is no cable connected in all front panel now, there is an error "niScope Fetch WDT.vi:5210001<ERR> Maximum time exceeded before the operation completed. Status Code: -200284". I searched some and it is because no trigger received by the scope to start the next acquisition of samples. So what should I do, to connect a right trigger line to the scope (perhaps more specific details of which channel to which channel, Thx)??? Here is how I initiate and configure the scope.

Hi, it solely depends on what trigger configuration you have for the digitizer.
