JP1 Remotes

It's only been like a year... I'm such a loser... anyways, I got an email asking for it, so I fixed the errors, and posted it back up.

Here is an explanatory clip from the page:

2 things wrong with the RCU810:
1. It resets all by itself ...

Jumper pin 1 to pin 5 - one is reset, the other is vcc - your problems will be gone. If you use a removeable plug, then you can take it off to program your rcu using the jp1 interface.

I tried 10K & it still wasn't 100% stable, so I did the wire jumper connected to a header thing. It has been working 100% ever since. I just haven't had time to take pictures & put them back up on the site.

And BTW, I have always used nimh batteries, and I also observed the sporadic reset with the ...

You're Welcome.
It's nice to hear that something I did was helpful. Thanks.

you indeed are the man, robman.

This what you need? :)

Sorry... stop the presses... the 100K isn't enough to keep the unit from resetting. Now I have to redo the webpage again... I think I'm just going to pull the whole thing off for a week now. Anyways, I guess the solution now is to have a header plug that dead shorts pin 1 & 5 that you put on the jp1 ...

Right you are... typical me there forgetting about JP1 I read 'JP1' in your original post and saw 'remote control' sorry... like I said - I didn't understand what the heck you were getting at - not of course it makes total sense... using a wire solves the self-resetting but you do have to remove it ...

First of all, let me set all worries aside - these hacks work. solidly. for about a week now.

My guess is that the other UEI remotes have a resistor somewhere (inside the CPU even perhaps) that pulls the RST high unless someone externally pulls it low to reset the CPU, and that this resistor ...

I documented a couple things, thought I would post them:

How to fix an RCU810 so it doesn't reset itself sporadically, and how to add a 'hard' backlight key.

Enjoy, feedback welcome.

Thanks again for all your help guys.

For anyone else who runs into this problem, I think the solution is to realize that creating an entire ungrade in KM (set of EFCs for your VCR or whatever [probably already in your remote anyways so it won't take a lot of memory in your remote] mapped to your ...

factory internal setup codes, no keymoves or anything like that... take remote new out of box, set up TV and VCR and AMP, watch a movie, switch to AMP to adjust surround settings, push VCR1 button to go back to movie, and VCR shuts off. Why? I have tried moving keys onto the device key & it doesn't ...

sweet. thanks.

and how do you get from ccf data to efc data?

First of all, thanks for your reply, I appreciate the help.

I had a huge reply typed in here, then when I found the EFCs I deleted it all.

So thanks again - I think you just saved me a couple hours of work.

I'm figuring this stuff out at roughly the same speed I'm finding the info, so just on the ...
