Considering the PXI-8420/16 as a solution for running one application to communicate to multiple devices.

I am developing an application that needs to communicate through a serial interface to several devices under test at the same time.Would the PXI-8420/16 be a solution??

Unfortunately, our serial cards do not do serial communication concurrently.

If the NI serial cards do not do concurrent communication, then how do they work? I have a similar application but the communication doesn't necessarily need to be concurrent. It just cannot be sequential. Maybe the NI serial cards will suit my needs but I need an explanation of their operation before I can determine that.
