Hello,
After reviewing the documenation on the USB-6009 I'm at a bit of a loss. How is the digital trigger (PFI0) configured internally? From doing some testing it seems as though it's configured the same as all of the other digital IO pins (as shown in Figure 15, page 22 of the user guide) because when left floating the pin reads +5VDC. This voltage then changes depending upon the load attached.
The reason I ask is because I'm setting up the hardware protection circuit (current limiting) and I'm directly connecting the trigger to another pin being used as a digital output. I'd like to make sure I'm setting it up correctly and that I won't damage the hardware.
Anyone with prior knowledge please weigh in. Thanks!
