JP1 Remotes

I am trying to use keymap-master 9.06 with my URC-8820 but most of the keys are mapped wrong (functions show up on the wrong keys). (Loading Gateway DVD remote file). Keys power, 0 to 9 (except for 3 and 8 swapped) seem OK. Most of the remaining keys are messed up in some fashion. Any suggestions as to what might be wrong and how to fix it? I tried figuring out which key is being mapped where, but quickly got confused. A couple keys seem to duplicate functions, also.

Yes, I set KM for the URC-8820. I previously programmed it with KM8.23 (for other remote replacements) which only had URC-881X instead. It seemed to work reasonably well although there were obviously some missing button assignments.

I did notice that some of my other programmed controls, which worked previously with KM8.23, did not after reprogramming with KM9.06 and modifying the key layout some.

Can anyone tell me how the URC-8820 was added to KM anyway? Perhaps looking at these details would tell me where things went wrong.

I added the URC-8820 to KM v9.00, using the data in the then-current RDF file for the remote. It works fine on my URC-8820 also.

I apologize in advance if I'm misunderstanding you, but I have a few things to clarify:

Thanks for all the input. I started back from scratch and reloaded with only the minimal key modifications. Now everything seems to work. The first time, I started deleting everything unneeded on the remote, first (including macros). Perhaps I did something wrong.

Now I have an issue with adding a Lasko fan to the URC-8820. This never worked with KM8.23 although it would load by selecting the wrong URC-881X device (no 8820 available). Now with KM9.06, when I select URC-8820, the protocol can't compute and lists a 3rd party protocol in the notes. When copying this to IR, IR modifies the upgrade device code and errors with "invalid character in input".

Any thoughts as to how to properly import this protocol?

Try using this protocol for the URC-8820

Upgrade protocol 0 = 01 91 (HCS08) Lasko_PB (PB v4.00)
20 14 20 49 11 C5 11 06 06 02 79 00 D5 00 D5 02
79 34 E3 FF FF FF FF FF 03 CC FF 5F
End

I found out what I did wrong and feel really stupid. I was pasting the protocol into the key moves, instead of into the protocol. (I did it right the first time. I don't know why I did it wrong later).

Anyway, I tried your new protocol for Lasko and the fan still doesn't respond. I am guessing that the only listed Lasko fan code doesn't work for my Lasko 3440 floor fan. Does anyone have the correct device code? (I lost the original remote, so I can't program the codes myself through the learn function).

Nope, sorry, this is the only example of a Lasko fan that we've seen.

I just ordered a replacement Lasko 3440 remote. I will probably need some assistance in creating a new remote code and protocol after "learning" (although it is only for 4 buttons).

By the way, the newer protocol (previously supplied) caused my URC-8820 to lock-up. Every time I pressed a button for the Lasko setting, the 8820 light would turn on and not go off. I had to pull the battery to clear it.

Fred

PS: Is there any advantage to using RM instead of KM? If so, how can I update it to include the URC-8820?

I found the Lasko 3440 fan remote (after ordering a new one), The learned codes turned out to be NEC1 Dev1 after all, using EFC 058, 059, 186, 186 for oscillate, timer, speed, and power, respectively.

Upgrade Code 0 = 37 C8 (CD/1992) Lasko_3440_fan (KM v9.06)
5A 00 10 00 0A C1 00 7F 7F 3F 3F 1F 2F 0F
End

The file has been tested and uploaded to home automation.

Thanks so much to everyone for helping and understanding.

Fred

PS: A new question: Is it possible to combine two devices into one (similar to merely learning new keys)? I would like to add the Lasko 3440 functions to my Infocus X1 projector device. Also, how does the remote know which device to assign learned codes to? IR doesn't seem to identify this and doesn't seem to work to reload learned assignments, unless I am just missing something.

I don't understand how to use key moves to combine multiple devices (such that a device is now left open for other use). Where can I read how this works?

How are more complex merges of two devices handled (where much more than 4 buttons are involved)?

Fred

PS: I did want to further commend the writers of KM. I thought that KM merely produced data files for relay to and from the remotes. I didn't realize that, at least in the case of protocols, it is transferring actual assembly language machine code to reprogram the processor. I am intrigued by this accomplishment in such a seemingly simplistic device as a remote. I coded machine and assembly language on more complete PC systems years ago, but am amazed that you accomplished it here. Thanks for an incredible feat and for doing so freely for the benefit of others.
