Using basic DAQmx drivers for a HS-DIO Card?

[Jick]

Hi,

I have ready-made programs for Non-HS-DIO cards which uses DAQmx drivers for example basic configuring, reading and writing.

Now I need to use HS-DIO card (NI PXIe-6535). Do I need to regenerate my code and use NI HS-DIO drivers or does it work with old ones? What do I miss if I use old drivers (if they can be used)? Other issues?

BR,

Hi Jick,

The 6535 does not use NI-HSDIO, it uses NI-DAQmx. I am not sure if your old code will completely transfer over, because the 6535 has its own subset of features that are not on other cards. However, it shouldn't be too much effort to modify your existing code to work with the 6535. Hope this helps.

Ok, thanks for that.

I am wondering why I can't create counter output task in MAX using this device? It says "No supported devices". Purpose is to output PWM signal.

Look at the specs!

We do not have counters on the 6535, but you can output a pulse train by streaming a 0101 bit pattern on the generation output continuously at the rate which you need it. To change pulse width, you would have to oversample and add bits, such as 011011, or 001001.

It has PFIs channels according to spesifications but drivers does not show them for Digital Output generation. What are the PFIs for? Timing? Do I need to use "normal" DO lines for the generation?

What does Supports Pattern I/O mean? Is there some special drivers for pattern generation?
