I'm using an Adaura programmable attenuator, and it's appearing multiple times in NI MAX. This is the first time I'm opening everything up this week and multiple resources are appearing. I've restarted my computer and unplugged/plugged everything back in a few times and nothing has worked. Top device is the correct device, can't get the other ones to disappear. help?

What "other" ones? I only see one instance.
Edit:
Do you mean that those other COM ports really don't exist and are just duplicates of COM5?

You appear to be using a (USB?) device that mimics a Serial Port having at least 3 inputs, COM5, COM6, and COM7 (notice that the Icon that MAX shows you looks like a DB9 plug, which went "out of style" about 25-30 years ago). Your Adaura device is plugged into one of the inputs, and the other two are not connected to anything, so show up as "available Serial ports" (a.k.a. COM ports).

USB to RS232 devices behave strangely when plugged into different ports. Sometimes it sees its own entries created from plugging in the device to a different USB port as a serial port and will use another COM port. It's entirely possible that those are actually the same device, just appearing to NI MAX (and I suspect device manager, although you may have to choose to see the hidden devices) as different devices.
