1409 can't read from RTSI bus with signal from 6070E

[Tom Hanna]

We are attempting to trigger a 1409 card.

An external trigger sends a trigger to the camera. At the same time over the RTSI bus, another 6070E card is triggered to output a pulse to the camera after an adjustable delay. The aim of this is to trigger the card after the acquisition time of the camera is over and it has begun outputting the picture.

The second 6070E is triggered alright, and produces a pulse, which is routed into the RTSI bus. However, the 1409 does not respond to this trigger.

Other RTSI things like synchronising data capture on the two 6070Es still seems to work fine, so I presume it must be something to do with the 1409, or with IMAQ.
However, I am using the second 6070E because I had
troubles routing the output of counter 1 into the RTSI bus from the PFI pins.

Many thanks for any help you're able to give,

TomH.

Tom, I have a couple of suggestions for you:

1. Your program does not follows a real sequence, that is, there is no way to tell whether the triggered acquisition was set up before the DAQ trigger or viceversa. You might want to put your program in a logic sequence to force the program to execute in the proper order. Use the error cluster to wire all the VIs together and not in different pieces.

2. I see that one DAQ portion references to RTSI2, the other one to RTSI4, and the IMAQ part to RTSI5. If the pulse is generated in RTSI2 then IMAQ should point to RTSI2 as well.

Check this suggestions you might find them useful. Good luck!
