Hello everyone,
I am using PXIe 6612 counter card to measure the pulse width of the signals on PXI 6528 DIO card. Both these cards are in the same PXI chasis (NI PXIe-1065). I could measure the pulse widths using the LabVIEW 2013 example Counter - Read pulse width and frequency (finite).vi example. However not all the channels of the PXI 6528 card are shown in the drop down list of channels on which pulse width can be measured. Trying to connect any channel other than those available in the drop down list returns error. On PXI 6528 card port 0,1 and 2 are input ports and port 3-5 are output ports. I can measure pulse width on port 0, port 3 and only line 0 of port 1 and 4.
Can anyone explain to me why don't I see port 1 or port 2 channels in the drop down list or force the VI to measure pulse width on these channels ??
I can connect PXI 6528 input channels externally to PXIe 6612 counter input channels and measure the pulse width, but If possible I would like to avoid the external cabling between the 2 cards.
