JP1 Remotes

I've just gotten my first JP1 remote (actually JP1.2), and before I mess around with anything, I want to create a backup of it so I can restore it if I have trouble. I found a lot of posts on the forum from people recommending making a backup, but no one actually giving the steps. And the RM manual doesn't have anything specifically about backups.

Okay, so I've got RM running, and the remote (a 10820N) is recognized just fine. The only menu option that looks promising is File > Save As. Is that correct? When the Save dialog comes up, there are two file types listed in the combo box at the bottom: "IR file (*.ir)" and "RM Remote Image (*.rmir)".

To make a backup, do I need to save a file for each type, or do I choose one? What are the differences? Also, how do I go about loading the backup back onto the remote when I need it?

Thanks for the help.

Thanks, I must have overlooked that post when I searched. That thread talks about using IR to save the backup, but I'm on Linux, so I'll be using RM-IR for my work. I should have mentioned that.

So should I just save the IR file (*.ir) and call it good? What is the other file type for (*.rmir)?

The 10820N has a fully mature RDF and no special OEM functionality so whatever kind of backup you did will be fine.

Best Practice :

Do a Raw Download and save as an IR file.

Both IR and RMIR make silent changes to the E2 area when downloading. This could be problematic in an OEM remote (A remote that came with your Cable box or TV...) or a remote that doesn't have a mature RDF. In these cases the silent changes might lose an OEM upgrade or some special setting.

So a best practice is to do a raw download to get an acurate picture of the E2 area prior to making any changes.

Tip: When creating an upgrade, always include ALL functions from the oem remote, even if you never plan on assigning them to a button. Complete function lists makes an upgrade more helpful to others.

For the 1067B, as received at our house, the usual keymove and macro region starting at $0608 is duplicated beginning at $0808. If the KMM area is changed, and the user wants to restore it, a 977 command will copy the $0808 region down to $0608. If the area starting at $0808 is empty ($FFs) then the user may issue a 988 command to copy the KMM area up to $0808. The RCA RCRP05B seems to work in the same way.

This has the effect that a user can experiment with keymoves and macros, and if the remote gets out of whack, the user can be instructed to do the 977 command, and the original KMM area is restored.

However, a 981 reset will erase the $0808 region. Is the "private area" somewhere else?

you got it right, I had forgotten that 981 really erases stuff. The "private" area is the area from $800 to $A00 (on the RCA, Atlas, etc)

I didn't realize that a 988 copies what's in the setup area "up" to the private area. That's cool.

I added 988 and 977 to the wiki.
