OK, here is my challenge. I am using Tonto to down load to my TSU 2000(Proto doesn't recognise my serial port). I am unclear about all the different flavor of codes here. HEX, Binary, OFA, EFCs, etc. When I go to look up codes for my DVM 1805 5 disk DVD changer, I get the following PDF from Denon.

[Link: usa.denon.com]

I've looked at the thread about Converting Denon codes, but I am still unclear about how to convert:

c1,c2,c3,c4,c5,c6,c7,c8,c9,c1,c1,c1,c1,c1,c1
0, 0, 0, 1, 0, 1, 0, 0, 0, 1, 1, 0, 1, 0, 0

... into any kind of code that I can enter into Tonto. Any protocol gurus out there who can help? Where do I start. BY the way, that link is to codes for a different DVM model, however my guess is that it will still work.

Cheers!
