NationalInstruments.DAQmx.DOChannels.CreateChannel

[Tim8w]

I am using the "NationalInstruments.DAQmx.DOChannels.CreateChannel" command to write data to the DAQ. I am looking for which functions to call to find out how many lines/Ports are available so I can create the first parameter...

Currently, I am hardcoding it to the following:

digitalWriteTask.DOChannels.CreateChannel("Dev1/Port0", "Port0", ChannelLineGrouping.OneChannelForAllLines)

I would like to be able to know how many Devices and Ports are available for the DIO card(s) installed on the system. Is there a call that will return this information?

Hi Tim8w,

you can use DAQmx property nodes to get this information.

Hi Tim8w,

The KnowledgeBase linked here will show you how to find all the devices in you system.  Take a look at it.  If you have any questions, let me know.
