Is there a way to trigger DAQmx with the same trigger as NISCOPEmx

[Splitufan]

I am using an ultrasonic machine to prduce waveforms. I need to capture the waveform and get a pressure reading that corresponds to that waveform at roughly the same time. I want to use an external trigger to trigger both. I am using a NI-5122 and NI-6224 with a RTSI cable between the two, but I am not certain the RTSI cable is setup correctly. Anybody got any answers?

Splitufan,

Welcome to the NI forums!  The NI-SCOPE driver will allow you to configure your trigger for a RTSI line on the NI 5122.  This is great news because all you have to do now is configure the actual RTSI cable and export your trigger from your NI 6224. 

1. To configure your connected RTSI cable, open up Measurement and Automation Explorer (MAX). 

2.  Expand Devices and Interfaces

3.  Right click NI-DAQmx Devices and go to Create New NI-DAQmx Device > RTSI Cable

4.  Now that the RTSI cable is created go ahead and Right click the newly created RTSI cable and add both of your devices (6224 and 5122).

 

In LabVIEW you will use the DAQmx Connect Terminals.vi to route the signal from a trigger line (PFI0…) to RTSI 0. 

 

When configuring your trigger for the 5122 you will specify the trigger source as RTSI 0.

 

I hope this helps!
