Issue Details

I'd like to use my HSDIO Card specifically to send RS-422 commands. Is this possible?


Although the  NI-6541 can mimic some of the commands from the RS-422 platform, it is not RS-422 compatible which means it is not suitable for sending or receiving RS-422 commands and should not be used for that purpose. NI does sell several PXI Serial cards which are compatible with the RS-422 platform.
