I think you are missing the frequency, but I suppose you could get that by trial and error. What is the target remote for your protocol?

Do you have a JP1 remote and a JP1 cable? And if so, which remote do you have?

If I understand your post correctly, this is what your signal looks like:

carrier freq: not specified
leadin pair: +1000 -5000
ONE: +1000 -500
ZERO: +500 -500
leadout pair: not specified
repeating: not specified

I guess we can assume that the signal doesn't repeat and therefore doesn't need a leadout, and has a carrier frequency of 38kHz.

Looking at the data that you posted for the buttons, I can see that there is a 1-bit checksum in the LSB spot, and the rest of the data is the OBC (which is 1 less than the keycodes).

Based on the assumptions that I had to make, I have created an upgrade here:

I have a JP1 remote URC-8910 and cable. You are right has a carrier frequency of 38kHz.

In that case, give my upgrade a try and see if it works.

If it doesn't, use your URC-8910 to learn the signals from the toy remote. Then test the learned buttons to make sure that they work, because capturing the signals from toy remotes can be tricky. Once you have a set of working buttons, load the IR file into the Diagnosis Area folder then post a link to it here so I can take a look.

Oh this is a robot! Do you think Jeff is working on the age old question of how we get the remote to bring us a beer? Laughing

Hi Robman,
I tried the upgrade code.It doesn't work. I use the Arduino to capture of date

below date from rebonova remote

It seems different from upgrade code

this is modified date of key 1

Sorry Rob,
My robonova remote didn't work 2 months.I can't use it.The information of remote data from web-site.And my URC-8910 doesn't have learn function.Can I add learn function on URC-8910?
thanks
jeff

Your URC-8910 *does* have a learning function, but it's of no use if your Robonova remote no longer works.

What is "Arduino" and how are you using it to capture the Robonova remote if it no longer works?

Do you know how to read the Arduino data?

Based on a guess, I've created an upgrade for the robonova

http://www.hifi-remote.com/forums/dload.php?action=file&file_id=9107

¥n323198 503 96 54 45 55 94 55 45 54 95 54 44 55 44 55 .....

KEY-01 "1" 1 10101 0x00
500 100 50 50 50 100 50 50 50 100 50 50 50 50 50 50 50 50 50 50 50 50 50 50 50 50 50 0

I think Arduino data this means
+5000 -1000 +500 -500 +500 -1000 +500 -500 +500 -1000 +500 -500 +500 -500 +500 -500 +500 -500 +500 -500 +500 -500 +500 -500 +500 -500 +500 -100000

Based an all that information, I created a different upgrade. I just wish that we had any other key than Key1 as a sample.
