DAQmxSetDOOutputDriveType equivalent under Linux?

My understanding, based on reviewing older messages posted on this forum posted as "recently" as about 9 months ago, is that the equivalent of the DAQmxSetDOOutputDriveType API function does not exist in the DAQmxBase package, meaning that it is impossible to programmatically switch the output driver types of the USB-6501 to active push-pull under Linux. Is this accurate? Have there been no updates to the DAQmxBase package in the interim that makes this functionality available? Is there a way to use one of the GUI tools once to set the driver types and have those "stick" and then run programs making use of the C API without having the driver types revert?

Thanks,

Berend

Hi Berend,

You can configure the DIO lines to be Open-Drain (+5V operation) or Push-Pull in Linux.  Please refer to the following KnowledgeBase for more information:
