JP1 Remotes

The only sure fire way to determine what sort of processor is in a remote is to create seperate protocol upgrades, one for each type, and see which one works. (the others should cause the remote to lock up).

OK, I'm going to take a couple more for Nils as well when I get home. I'll break on down and get some pics of the board as well.

Not real sure if this may be helpfull, but I u/l a IR save from my SA Exp3 after doing a 981 reset to yahoo here.

The sun is out here today (finally) so I'll try and get some more pics in a bit. In the meantime, one of mine has a sticker on the board that is legible and says;
312124792111
RC1830-EX01
013101 A4L3 1580
ASSEMBLED IN MEXICO

The board is stenciled;
RC-1801

The printed users guide for this remote says it is a "Model ER1"

It uses the "ER10 (Sc Explorer 3).rdf"

We have downloaded the new "Scientific-Atlanta ER1 RDF" from the Yahoo files area, and opened IR with that rdf....when we go to create a macro , the A, B and C buttons are available to put macos on, but when we upload it to the remote, we get the error msg that the signatures are different, and the remote won't work. When we used the old ER10.rdf, we can get the Sony STR K750P Upgrade transfered over from KM to IR, and the remote will operate the rcvr form the VCR button as desired, but the A, B and C buttons are not avail to create macros on.

Thanks for any help...

When you get the error message are you replying OK? If not try that and see if it works.

The question for Rob or Mark is related to IR. Is IR handling the alternate signature in the fixed data of the RDF?

Yes..we reply OK...

Sounds like more than the signature is a problem so lets see what Rob or Mark think.

Actually, this one is for MikeE as he's the guy who figured out every thing that this remote can and (more likely) can't do.

The main signature in the old and new RDFs did not change; it's still "ER10". The new RDF does add FixedData support for the secondary signature bytes, but IR does not understand this to be part of the signature, so it's error message about signature mismatches would not have anything to do with the secondary signature.

I'm not clear on what you mean by this. The proper way to update the RDF is to rename or delete the old RDF and add the new RDF. Then open IR and download from the remote. Regardless of what RDF IR was using before the download, it will select a matching RDF for the new download. When you do this, does it select the new RDF automatically? If so, then the signature in the remote matches at that point. Then try to upload to the remote with the just-downloaded data. If it works at this point, then try making changes.

If you still have problems, do a 981 reset on the remote. Then remove both RDFs (always do this when IR is not running), run IR, dowload from the remote, save the IR file, and post it in the diagnostic area in Yahoo so we can take a look at it.

We did exactly that..moved the old RDF to the desktop, we found the new RDF at the yahoo site, "saved target as" to the same folder as the IR.exe resides in. Opened IR, and downloaded the remote to IR. I believe thats when the error mesage arrived.

We are not even sure if this remote can do what it's owner wants to do...that is, turn on his cable box (yes it can) and the TV which is plugged into the box (yes it can), turn on and transport control his Sony DVD player, and control input and volume on his Sony sourroud sound amp XXX750X (it can with the old RDF) and have a couple of macros assigned to 2 of the A B or C buttons. These buttons are not available using the old RDF, but are available with the new.

If only he hadn't seen the JP1 connector! He WAS happy using his 2116. LOL

Thanks Mike, and all for you help ...It becomes more a challange then a necessity.

It's possible that IR is getting confused somewhere along the way and thinks the remote should have an 8-byte signature. Being an older remote, this remote only has a 4-byte signature. In other words, the error message may just be IR getting confused, and not be meaningful. If the signature in the EEPROM was really incorrect, it would not work with the old RDF either.

In any event, IR does not know how to initialize the Multi-Macro (A, B & C keys) control area of the EEPROM, so you should always start by downloading a working image from the remote. If you want to start clean, do a 981 reset on the remote and start by downloading that.

Since there are no keymoves possible on this remote, you'd have to create Device Combiner updates in order to get the volume/mute keys to control the amp, unless you can get the Sony DVD upgrade to control the Sony amp and use VPT set to VCR for TV & cable.

I remember pestering Rob about this JP1 remote back on the Yahoo list a couple of years ago.

I was trying to program it to use with an Apex DVD player, and got nowhere at all. At least I wasn't alone in my incompetence.

So this remote cannot be programmed?
