JP1 Remotes

I want to Move Codes from from LG Remote to my Atlas DVR remote.
Picked up a One for All URC-9911 in order to learn my codes- Have 30 days to return it.

I would be happy with just these functions:


LEARNED SIGNALS:
# Device Button Key Protocol Device SubDevice OBC Hex Cmd EFC Misc Note
1 DVD Power NECx1 45 45 48 F3 149
2 DVD Play Unknown 36.866 KHz Signal
3 DVD Select Unknown 37.383 KHz Signal
4 DVD CH+ Unknown 37.209 KHz Signal

How do I convert my unknown signals to known signals using IR?
#2 Play is:

Apparently I needed to tap the key on my LG remote while in learning mode---- not hold it down until the code was learnt.

1) I hate looking at IR raw data in this form, rather than looking at the .ir file in IR.EXE myself. So I might be missing some secondary detail.

2) The batteries in the LG remote are too weak for good learning. (There are no + durations shorter than 500 in any correct learn of this type of LG signal. The first symptom of weak batteries is that many + durations show up as unreasonably short, as they do in the numbers you posted).

3) Learning with a short tap is generally a bad idea and will typically give worse results, and this protocol is not one of the exceptions. If it improved things, that is only because it places less of a load on those weak batteries.

4) Devices using NECx1 45.45 are pretty consistent across models. Now that you know that is what you have, it should be pretty easy to find a file here or at RC that has all the rest of your IR signals.

I solved this problem by using a chemical I use for cleaning interconnects all over my av systems.

In my case I have a couple of 90's vintage Nakamichi remotes that always gave URC remotes a very hard time - even when new. Mostly they'd decode just like your codes above, or occasionally the wrong protocol altogether. My success rate was about 20%. That was under good conditions.
- fresh batteries
- Optimal distance (closer than normal in this case)
- 4x40w (or less) incandescent ceiling lighting in a 10x12 room

Interestingly, they NEVER failed to operate the Naks they controlled, even when fired at large oblique angles. I concluded the URC was a poor learner of Nak codes. Now that I know the Nak uses the NEC1 protocol, I find that to be unlikely!

After using Caig DeoxIT on the batteries and battery contacts, my success rate is above 90%. Optimal learning distance was normal. So essentially all you need is a second try relearning the wacky codes and you've got em all.

The contacts didn't look bad when I started, my remotes are stored in a dry place without batteries since I rarely use my oem remotes for anything but teaching a universal remote. But after cleaning up the contacts, now I can see clean metal, and where a little more cleaning would help! Needless to say the next thing I did was gather my remotes and do them all. Now they're protected from corrosion for perhaps 10 years.

I use the liquid with brush in a 7.4 ml bottle, part number D100L-2DB. I got it from Parts Express. The PE Part Number is 341-215. Under ten bucks. For plated stuff which is clean, I highly recommend ProGold G5 5oz spray, part number G5S-6, PE part number 341-225. These products work well together, so I'd get them both and be done with it.

I hope this makes the whole learning process go a lot easier for you, too!
