What advantage is there in using the NI USB-232/4 over an offset USE to Serial hub?
I have an application that requires LabVIEW control of 19 instruments that communicate over RS-232.
I've read the data sheet for the NI USB-232/4, and I don't see any advantage of spending $528 for this device (times five) over an off-the-shelf USB to Serial hub for half the price.
Can someone tell me if there's an advantage to the NI USB-232/4 or if they've had experince with one?
Thanks in advance.
