How to convert Pronto hex code to OFA code?

[ozben]

I have found the discrete code for my Marantz DVD player for the Pronto. How can I translate this into a code that I can use with my OFA 8811?

Do I use the IRTool? If yes which codes do I use for JP1?

The code is:

Power Off

0000 0073 000f 0013 0008 0030 0010 0010 0010 0010 0010 0010 0010 0010 0020 0020 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0020 0010 0010 0020 0010 0010 0010 0bbb 0060 0020 0010 0020 0010 0010 0010 0010 0030 0030 0010 0010 0010 0010 0010 0010 0010 0010 0020 0020 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0020 0010 0010 0020 0010 0010 0010 0bbc



Power On

0000 0073 0007 0014 0010 0010 0010 0010 0010 0010 0020 0010 0010 0020 0010 0010 0010 0bbc 0060 0020 0010 0020 0010 0010 0010 0010 0010 0020 0020 0010 0010 0010 0010 0010 0010 0010 0010 0010 0020 0020 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0020 0010 0010 0020 0010 0010 0010 0bbc


Thanks for any help,

If you decode either of those with IRTool it reports RC6 protocol, device 4, command 12 (EFC 050). I assume that is the power toggle command for your DVD.

If you use normal JP1 methods to reproduce that signal, I expect you would reproduce the power toggle.

They both look like unclean learns. Maybe that distortion from a perfect power toggle is the reason it works as a discrete. If that were true, you'd need to understand more about why it works before you could reproduce it.

I thought Marantz had clean discrete codes. Maybe this Pronto Hex you found is just wrong.

Anyway, Jon knows more about this topic than I do and will probably jump in with the right answer soon.

There is a big ccf file at the Marantz website that has commands for many Marantz devices.

According to that, Marantz DVD's apparently use RC5x:4.12:1 for ON and and RC5x:4.12:2 for Off

You will need to add the "no button" device upgrade -- already set for the 8811

Upgrade Code 0 = 36 82 (Cable/1666)
73 00 01 1B 1B 1B 1B
End

Then using Key moves in IR using hex (not EFC) assign these to the keys of your choice:

Discrete On=CF E1
Discrete Off=CF D1

I have also posted a device upgrade in case some one needs this for another Remote model .

John and Jon thank you very much for the information. The device upgrade worked beautifully.
