Using a digital I/O module on a cDAQ as a UART interface

Hi all!

I have a cDAQ-9174 with an empty slot, and I need to communicate with a board which has a 3V UART interface. Can I use a digital input and a digital output of a digital I/O C-module in order to generate a UART interface? Of course, I wouldn't like to "build" the RS232 protocol myself in LabView, but I'm looking for a simple solution.

Which C-module would be my best choice?

And, if this is not possible, have you got any suggestion on how to solve? Maybe a NI-9411 with an external UART-RS422 converter could do the job, could it?

Thanks in advance for your help.

Regards,

Stefano
