Non-ASCII Characters - E1.20 RDM (Remote Device Management) Protocol Forums

Yes, null termination of strings is allowed.

10.1 says:
Text fields shall terminate based on Parameter Data Length, however if a NULL is encountered then that shall also act as a terminator for the text field.

So, in your "QUADRATIC",<0x00>,"abcdefghijklmnopqrstuv" example, the receiver should display "QUADRATIC" properly.

Personally, I don't like null termination, I think length termination is more in keeping with the spirit of RDM. But given the number of C programmers in the world that are more comfortable with null termination, there's nothing wrong with using it.
