Hi,
I am using a PCI 6259 DAQcard (with a SHC68-68-EPM cable and version:2.9.1f0) to get an analog signal and a digital signal. The analog signal is used in NI MAX or NI Signal Express (DAQmn 9.7.5) to trigger it with the digital signal. When the digital signal is mounted on a Px/x port I can detect it. If I want to use it as a trigger signal on a PFI x- (better PFI x/Py.y-) .port I do not get any trigger quantitiy.
With a NI USB 6008 everything works quite well. Remark: The digital post is just labled as: PTI 0 and not as in the case of the PCI 6259 on the NI CB-68LPR-board: PFI x/Py.y.
Another remark is that I did not measure a voltage difference of 5 volt at the provided port.
How can I fix the problem and use a PFI x/Py.y-port for a digital trigger?

Hello MarcusHd,

Hey AndGar,
by trying I found one chanel on the platine with give me an trigger signal. So I can measure something but not in every chanal.
Maybe just the PFI x- ports are reserved for triggering and you need to close every other task which measures a digital signal.
*actuall I have no access to the programm*
Thanks and best regards,
Marcus
