JP1 Remotes

I have just gotten one of these and would like to use discrete power codes. I dont find them on any device upgrades and no luck trying pronto ccf codes. Next step is to try a bunch of codes. If I shut it down with a code, I can easily take it back at this point. I need a strategy. If I am going to try a range of codes, would that be OBC, EFC, or hex? Any other suggestions would be appreciated. I promise to share any positive results!

Thanks for any help.

Do a search for Cyberhome threads. There aren't that many. I think people haven't found discrete power codes. But it's your chance.

RM doesn't have a sheet showing the missing functions like KM does, but you can still get there with little effort. Assuming that this upgrade works for you for the most part, in RM sort functions in OBC sequence (just click on the OBC column header). It's easier than EFC I would think.

Try the numbers which aren't on your functions tab in RM by making temporary upgrades and writing notes as to what works what doesn't.
I don't know a thing about NEC1 devices, but I see a large gap 32-63 worth trying, which might be repeats of existing commands. 66, 67, 79, 71 ... and the numbers over 93 up to 95, 127 or 255 might get you somewhere to the discovery of more than just the power codes.

The difficult part is that a code may not look functional unless something else precedes it. I never figured out a clean way of handling the multistep ones.

I have a Cyberhome player, but have not found any discrete power commands. If the recorder is like the player however, "Play" will operate as an "On" command as would "Eject" but you would probably not want to always start by opening the tray. If similarities exist then "Stop" or "Stop" twice, would eventually turn the machine off after a time delay (if the screensaver is active).

I think the thing about NEC1 devices is that a lot of them do have a large gap from 32 to 63 and from 96 to 127 so these gaps aren't the first places to look. Some upgrades have discrete codes near to an existing code (e.g. DiscreteOn and Off next to Power) but most NEC1, Dev0 devices seem to have the codes all over the place. Looks like build a dummy upgrade, try out the codes and takes notes is your best strategy. There is a small risk of entering an irretrievable setup code but this usually seems to afflict tuners and audio gear rather than DVDs.

That's true; you might need to do a second run by pressing Menu before each trial code if you were looking for arrow keys, for example.

As Mr 7501 says, sometimes you won't find a code because one doesn't exist so you "create" one by using other functions such as Play, [Pause], Stop=DiscreteOn or Stop, Power = DiscreteOff.

That's very true. While there are no "rules" per se that I know of for using the NEC protocols, and there are many devices that use OBCs from the "forbidden zones", if you notice that the 32-63 range is unused, it most likely means that it was skipped on purpose and I would agree that this should not be the first place that you would look for secret functions. The same would be true for all the other ranges where bit5 is set, ie 96-127, 160-191 and 224-255.

Having said that, if you're going to do a complete search, you would try every un-accounted for OBC in the 0-255 range, I would just recommending testing the "good" ranges before the "forbidden" ranges.

Thanks everyone for your help. I am always amazed at the willingness of the experts in this forum to help. Unfortunately I had no luck. I tried the non 5th bit codes first and then just tried the whole range from 1-255. I only tried turning the recorder on. So it is possible there is a discrete off in there but I wouldnt think so.

Steve thanks for your suggestion I would not have thought of that. I could not get it or anything similar to work. This and the ILO seem to have different codes from the other Cyberhome players. I guess I have just been lucky, all of my other components have discrete commands.

Thanks again everybody.

If all attempts at finding a discrete On/Off have failed, and no workarounds (Play-Stop, eject-stop, etc.) work, perhaps you might be interested in the ToadTog special protocol. It allows your REMOTE to keep track of whether or not your gear should be on (based on sending - or not - the Power signal), and then will send it only if it "needs to". ToadTog requires use of the extender, but it might be worth your time to check it out.
