First I checked that there wasn't a hardware fault. A friend who's a computer programmer connected the Suite 16 to a PC and sent the text commands in the ADA documentation from that, which worked fine (we could hear relays clicking and the LEDs changing). After that we also send a 'reset to factory defaults' RS232 command, also in the ADA manual which may have helped. (Thanks Stuart!).
So then I knew the problem was related to the Pronto system. I had a feeling that it was something to do with the carriage return 'character'. It looked to me like ProntoEdit wasn't treating carriage return as a character because when I went into the command codes I'd already typed in and hit 'end' the cursor was immediately to the right of the character before carriage return, in the same way as if I'd never typed carriage return.
When I was asking my friend about the carriage return command he had mentioned that in hex, carriage return has a specific character code.
So I tried translating all the text commands in the ADA set up document to Hex using an online translator. The `character translates as: 60. The translator didn't convert 'carriage return' correctly, but I found elsewhere that it's: 0D.
Once I converted the commands to hex, everything worked perfectly!
So the 'volume up room 1' command above is: 60 53 56 4C 55 50 52 30 31 0D
By the way I also have a Suite 8x8 which I also couldn't get to work, and I got that working in exactly the same way as I did with the Suite 16. It seems to use the same commands too - it's best to use the list of commands in the Suite 16 manual because the 8x8 manual is somewhat sketchy.
