multiple NI USB-6525

Solved!
Go to solution

Hello, i intend to plug 3 NI USB-6525 into a PC to achieve 20 SSR switch.

 

how NI MAX will differentiate the 3 USB device?

can i make a fixed "alias" to a particular USB-6525 so that even if i plug it to a different USB, NI MAX still able to link this "alias" to the same particular physical USB-6525? 

 

if not using alias, does the "VISA resource name" in NI MAX can be use as unique identifier? such that i plug 1 particular USB-6525 to a different USB port will resulting the same "VISA resource name"?

 

Thank you.

MAX will differ those 3 DAQ cards by their serial number.

And you can give them different alias names: the alias too is linked to the corresponding device by its serial number.

 

Additionally you can read the serial number using DAQmx properties so even your VI can differ those 3 DAQ devices independently from alias name…
