I am trying to update a small VI involving NI-6534 (Traditional DAQ 7.5) to NI-6535 (unfortunately TDAQ is not supported) with Daqmx 8.8.
I have been wondering how Daqmx handshaking(8255) actually works.
I know that in Traditional DAQ, there was fixed control lines for the NI-6534 (REQ, ACK ...) and you could simply configure ports as output with handshaking parameters.
However, I do not see any of these signals in the NI-6535 ( I think they are called PFI something), moreover the Daqmx Timing.VI (Handshake 8255) doesn't specify any source for REQ or ACK.
So the main reason I created this post is to ask how does Daqmx works and by the way ask how are these control lines used since I need ACK and REQ signals.
I admit that I am not sure of any statement above and please correct me if I might have misinterpreted anything.
Please find enclosed both card pinouts.
Thanks in advance
