continuous digital output using USB-6211

[tim_wen]

Hi,

I am trying to use the LV example "Cont write dig port - Int clk.vi" to generate a pattern.

But I keep getting the -200077 error about the sample clock. The pop-up error message suggests

using "on demand", but there's no such choice with the DAQmx.

Any hint?  Thanks.

can you post your vi...if you did it in daq express, you can double click the icon on the block diagram and make that choice or change the clock sample mode to finite

VI attached...

thanks.

I don't think the hardware on the 6211 can support that generation mode.

If you look in Example finder with that example selected, down on the lower left it shows what hardware the example supports, typically the 63xx series cards are shown.

This is correct. The USB-6211 does not have a digital timebase - only analogue. That is why the X series (63xx) cards are only supported for this example.
