HI Guys,

Just learned some commands on my RCRP05B remote.
When I select "Convert To Device Upgrade" nothing happens, no warning messages or error messages.

The protocol is a weird one, never seen anything like it before, which is why I had to use the learning remote.

All I am seeing is each command has a unique start bit or leader (both the same width), then the 3rd bit is always the same, 630 uS. The command then repeats after 100 mS.

Could this be why rmir is not working when I select "Convert To Device Upgrade"? Under protocol it shows ** NONE **.

While photos and stuff are nice, what folks really need to see is your RMIR file. And when you post it, please include as many learns from the new remote as possible, don't just include one.

I tried to build a new protocol in rmir, however there are no commands so the signal structure drop down list won't work.

All these commands are just a leader low then high (both the same duration), and one bit low for 630uS (this is always 630uS for every command).

For each different command, the leader duration changes.
i.e. volume down = 3200uS low then 3200uS high
volume UP = 2600uS low then 2600uS high.

I tried to get it to work by copying the signal data for each command and pasting it in the learned signals tab. I thought this would have worked, but it does not. Just wondering if there is an easier way to get these signals to work in another remote.

I extracted the raw signals and run the result through IrpTransmogrifier (analyzer with repeat finder) and got:

Thank you for responding to my post. I appreciate that you took the time to help me.
The remote is from a small under counter kitchen radio.
The remote does work,and the learned commands work from
the learn RCRP05B remote. I even verified the RCRP05B remote
with my logic analyzer. Both original and RCRP05B remote signals
are almost identical.
I don't follow the output from IrpTransmogrifier.
I assume these values indicate milliseconds?
5,-5,1,-103m
So 5 milliseconds high, 5 milliseconds low, 1 millisecond low
then 103 mS high?

What I am seeing with the Logic analyzer is:

This is a new protocol that to my knowledge we have not seen before. So I would request that you give us exact data on the manufacturer and model. And the thread should be given an appropriate title and be moved to the protocol decodes subforum, imho.

The radio is my Aunt's. I will have to go over there to get specifics, model, etc. I asked her but she doesn't know what it is.
Since my last post I read up on "ProntoEdit's IR Display Format" so I was able to understand it a little better.

Some of the learned signals from my RCRP05B remote didn't work perfectly.
I was able to edit the learned data. When comparing it to the original & with the logic analyzer, I got it to match perfectly.
I managed to get it to work in an old atlas B01 remote I have here. When programming this remote, RMIR shows the learned data tab.

My goal was to get the signals working in an atlas B03 remote which is the remote my Aunt uses for her cable box.
Trying to edit the B03 remote file in RMIR, there is no learned tab displayed for entering in the learned data, so I don't know
another way to do it since the convert to device upgrade is not working for this strange protocol.
