JP1 Remotes

...so do I understand correctly then, that the URCs with eg JP1.2 have an EEPROM and programming the remote actually programs the EEPROM?

WOW that is really cool - I remember very long time ago how difficult it was to program EEPROMs - one needed to use IR to burn it permanently as far as I ...

I was wondering how long I can have the remote programmed without batteries. If the learned devices and key moves are lost after a while.

By the way, how are the codes "programmed" into the remote - is it a real permanent storage or some kind of temporary way that needs power?

no its a jp 1.2

Oh of course - you are certainly right - that does not work in my case!

I was too fast with my reply....

1. I will check back with some users if they would like two separate buttons for on/off - but another main reason why I hesitate is that I have to figure out so many dicrete on/off buttons - for each receiver that I program and for the TV which should be similar to some Hitachi ...

About using an extender - after what I understood, I would not want to use it - its too complicated and risky.


Finding discrete codes and using two buttons - I am afraid - will not be accepted by the end users who is used to ONE on/off button.

However as I learned now, resetting the remot e will ...

I actually dont need to delete the learned signals - ideally I would like to deactivate the reset, so that users cannot by accident delete my key move and the macro with 980.

Is there a way to learn key moves with the remote only ? macros are easy but key moves are not possible as far as I know ...

Yes - I thought it would only delete the learned signals.

Is there then a code that only deletes the learned signals leaving the rest?

Now that I finally finished the on/off macro for the TV & SAT I realized just now that a remote reset (code 980) kills the key moves and the macros - the devices remain.

This is rather bad in my case since I prepare the remote for other users and they certainly cant fix this themselves.

Is there a ...

Wow - I sent my last post without having seen yours.



THANKS VERY MUCH That did it!

Now I understand - Yes there is really a problem with this toggle bit - I saw it in the T=0/T=1.

This causes a really strange behaviour - Why does it work on a key incl. key move but not in a macro?

Is there a solution to that? Or do I have to give up since its a RC5????

Please advice!

Actually I thought it would be quite easy but somehow I dont get it.....


Like many I like to use the Power key to turn on/off two devices in SAT mode.
cond time turns it off - no need to press "PPV" in between.

I am really lost - please help

Thanks very much.

Thanks Robman...

I uploaded my files now.

Good idea.

...and yes you are right, for this remote all key codes that I program on key 3 and 4 are exchanged.


Sorry, but I dont know how to upload and link the files.

Now I am worried if this happens to other remotes I programmed (eg nec1) or only to the RC5 protocol.
