using counter n internal output signal as I/O clock

[loster]

I'm a green man for the Labview and DAQ card.

the DAQ card I was used is PCI6259. now I want using the digital I/O to generate some digital waveform.

the example VI I used is "Write Dig Chan-Ext Clk.vi",

when the clock source is selected as 10Mrefclock, it can works. but when I select the clock source as Ctr1internalOutput, the program can't run.

so my question is what should I do when I want to using the Ctr1internalouput as the clock source for the I/O?

I know that the counter can be used as the frequency division, but I don't know how the set in the Labview. do anyone has any example VI?

Thank you for using NI discussion forum. To generate a digital pulse train, you can using LabVIEW example Help -> Find Examples, try this one Gen Dig Pulse Train-Continuous.vi
