Hello,
I'm using a USB-6501 for my project, but I'm encountering an issue with the I/O configuration. By default, when the DAQ is connected to the PC, the output lines are set to active drive (push-pull), and thus remain at 5V due to the internal pull-up resistors (4.7k).
According to the datasheet, the output drive type is software-selectable. However, I haven’t found a way to change this setting, either through LabVIEW or directly via NI MAX.
How can I configure the DAQ outputs to be active low when the device is connected to the PC ?
Best regards !
