Apparently, there's a glitch in NSP where serial commands that use a combination of ASCII and HEX characters won't work. (Pioneer displays are cited as example components.) Nevo's knowledge base says to convert the ASCII characters to raw HEX in the serial string.

Well, I'm new to serial control (just starting to learn), but one of the first components I have to deal with is, in fact, one of these Pioneer displays. Could someone show me specifically how this "translation" should look? Here's an example of a Pioneer command (discrete command "Input 5"):

02h * * RMC S05 03h

TIA!
