Not sure I understand. So what I read some time ago is not true and that ASCII is nothing like NMEA-0183? Is that correct?

Or are you saying that two NMEA sources will not work with a NMEA multiplexer? (It does for me)

I have NMEA data sent from my sounder and GPS to displays on deck for the scientists, to my Nav computer to run my Nobeltec chart software and to a few other computers for data logging. I do understand that NMEA 0183 data is one way only.

Am I understanding things correctly?
