No output from DAQ card

[fudanlab]

Hello,

Thanks for posting the code. It offers the exact functionality I need for testing. However, when I run the code using similar hardware (PXIe-6366 and PXIe-6341), the interface looks fine and it seems to be scanning (either focus or grab), but there is no output from the DAQ card for driving the galvo mirrors. The same cards work fine in Scanimage. Do you have any suggestions for troubleshooting?

Thanks,
Dan

I’d doublecheck if the trigger and sample clock connections are set up correctly (the wires as well as the software settings), and use an oscilloscope to confirm that the trigger signal is indeed sent. If that doesn’t help, you could also start with just one card (e.g. PXIe-6366) and make that work before setting up the slightly more complicated synchronization across cards.

@fudanlab did this resolve your problem, can we close the issue?

Sorry for the long delay. I was traveling for the past week and just got back. Before I left, I did test the trigger and it seems like there is an output. I should be able to test it in the next a few days and see if it works as expected. Thank you so much for your help.

Hello, I would like to reply back that after troubleshooting all the connections, the program works as expected. The trigger connections are really important, which is something I missed earlier. Thank you for you feedback. You can close the issue now.
