Feedback to Guage on Denon

Adding Feedback to denon system

Step one Look at at RS232 protocol spec

 
The example of a command   * <CR> is the meaning of 0x0D. 
  SIDVD<CR>  :  Select Input source DVD
  MSTHX SURROUND EX<CR>  :  surround Mode Set to THX SURROUND EX
  MVUP<CR>  :  Master Volume UP
  PWON<CR>  :  system PoWer ON
  PWSTANDBY<CR>  :  system PoWer STANDBY
  SI?<CR> : Request command for now playing input source >> Return RESPONSE 'SI***<CR>'


This is great I can change volume and Inputs to the system.
here is the Protocol for the AVCA11SR:  http://vandermehrn.com/lc/AVCA11SR.pdf



What does it say about feedback? Well Page 9 Says:


So I write the REGEX and test it.

the structure is:

MV80\x0D

Here are 2 Regexs that can capture the value:

^MV(\d{1,2})\\x0D$
^MV(\d*)\\x0D$
Both give me a capture of 80

So now I enter the FEEDBACK and the ANALOG JOINS (see combined image below)




When I change the volume MVUP\x0D or MVDown\x0D

Nothing happens to the guage.

What am I missing guys?

I have been trying feedback for days following my RS232 post.
Look at the indignity of two buttons for Screen up and Screen Down. and Projector On and Projector Off.

Fiasco has a great work around I cannot use for adding 2 commands to a button. (it needs feedback)
I am reading the manual correctly or missing anything out?


I have read it so many times I dream about it seriously....
