DAQmx Push Pull Mode under C# NET

[Fred1204]

I don't seem to find anywhere a solution to change the Digital Output to a Push-Pull Mode. Many message indicates this is possible, simply look the DAQmx manual.

The only thing I was able to find is the DOChannel.OutputDriveType property to select the type of Output I desire.... OK, but with which function do I use this property.... Don't seem to find anything valuable anywhere....

ex:

if (DaqSystem.Local.Devices.Length == 0) return;

            try
            {

                using (Task digitalWriteTask = new Task())
                {
                    //  Create an Digital Output channel and name it
                    sLine = string.Format("{0}/{1}/{2}", sNameDevice, "port2", "line3");
                    digitalWriteTask.DOChannels.CreateChannel(
                        sLine,
                        "TimeOutWhite",
                        ChannelLineGrouping.OneChannelForEachLine
                        );

      DigitalSingleChannelWriter writer = new DigitalSingleChannelWriter(digitalWriteTask.Stream);
             writer.WriteSingleSampleSingleLine(true, !boAff);
                  }
            }

So what function is required to change the output type of port2 ??

Hello Fred.

Hi,

could you give us the reference of your DAQ card?

You can access to this property with the "channel property" function. I don't have the DAQmx reference manual here to help you more.

It's ok, I received a response.

Thanks a lot

Hi Fred1204,

The OutputDriveType is a property, so you have to set

digitalWriteTask.DOChannels.All.OutputDriveType = DOOutputDriveType.ActiveDrive;
or
digitalWriteTask.DOChannels.All.OutputDriveType = DOOutputDriveType.OpenCollector;

The output drive type of the NI-USB 6008 is always open-drain and cannot be changed to push-pull.
Please don't hesitate to get in contact with me by responding to this post

Best regards
