Trigger

[nicrodemo]

We’re using a NI9250 Sound and Vibration module and a USB-powered data acquisition module (cDAQ-9171) to acquire accelerometer data in channel 0. I would like to trigger data acquisition when a 5V signal generated by a high speed camera is received in channel 1. I have used the DAQmx Trigger VI in LabView NXG to try doing this but the 5V signal does not appear to trigger the data acquisition. The program runs but no data is acquired after the 5V signal is produced. Any help is much appreciated.

NI-9250 does not support the analog trigger. cDAQ-9171 does not have any PFI port to receive triggers.

There is no way you can do triggering with cDAQ-9171 and NI-9250.

This won't directly affect your problem but did you say you were using NXG?

NXG stopped all development officially in 2021 and will never get another update.  If it's not too late to back out and go to "standard" LabVIEW... do so.
