Sampling rate for usb 6009 device

Hello, 

 

I am a newbie to this NI usb 6009 device. 

What I'm trying to do here is to hook up a cable from a D-sub cable and collect digital signal.

I have noticed that this device is suitable for collecting at every 500 ms. Is this correct?

I need faster sampling rate and can't find how to do.

 

Currently the only way I can collect is by setting device manager as 'on demand'.

 

Thanks in advance for your help!

Yes, you should certainly be able to collect data every half a second.

Have you tried the 'DAQ Assistant' tool (found on the Measurement I/O / NI-DAQmx palette) ? It will guide you through the setup needed to create the code to configure your hardware.

Thanks Ian, 

 

Actually yes, I could collect at every 500 ms but is there any way I can collect more frequently? 

Such as every 10 ms or less? 

Using 'DAQ assistant' I could only use 'on demand' functionality.

When you look at the specs, notice that the digital I/O is software timed. You cannot specify anything other 'on demand'. You may be able to acquire as fast as 10ms but it will be subject to quite a bit of jitter.
