Looking for someone familiar with using a NI6534 for bus control.

Going through a learning curve when using a NI6534. Using waveform editor with device and having problems with reading data that is present on the bus.

Hi Chinook,

Typically when you are using the 6534 it's some sort of clocked I/O.  So you will read or write data from your port and based on a clock it will latch or output a value.  You will then have to interpret what that value means depending upon which communication protocol you are using.

I know that's really basic, but the question was really general, and I'm not sure what sort of problems you are seeing.  Maybe you could tell us a little more about your setup and how you are trying to read the bus in a waveform editor.

Finally, here is a link that might help you with better understanding how the 6534 works (I would recommend using DAQmx, because it makes the whole process much easier, particularly with these boards).

Also don't forget to look at some of the examples that are included with the drivers:
