I do not quite get this!
I am feeding an external digital TTL 5V pulsed signal to USB 6218 on Port0/line0 terminal and setting it as a scan clock i.e., to PFI0 terminal.
However, the task (ext triggered analog output) ignores the external clock and runs irrespective of what terminal I assign the scan clock to or even when I unplug the external signal. This is weird!
For example if I set clock to PFI12 when in reality the external signal is on PFI0, I still am able to run the task.
I tried the same on a different USB DAQ (6366) exactly same process, identical signal and there it behaves properly i.e., if the clock signal is removed or wrongly assigned the task 'times out' which is expected behavior.
I looked at the manual of 6218 and it does appear that I can use triggering on the PFI0..3 channels.
So what am I missing ?
Looked at Max configuration. Looks good. However, Max does not show up Port0 in configuration mode and only shows Port1 for Powerup option. Not sure what that implies?
Is the device damaged?
In the 'test device' on Max I see Port0/line 1 blinking because I have the digital input.
Thanks
