JP1 Remotes

There have been several requests in the past for a version of the URC-6131 extender that will work in factory-upgraded remotes that only have a 1K-byte EEPROM. I have ported the normal 2K URC-6131 extender to work in these 1K remotes. You can download it here.

Because the factory-upgraded remotes always come with a 1K EEPROM, it's not as easy to make an extender work and still leave enough room for upgrades, keymoves & macros. I managed to squeeze a few bytes out of the full version, but there's still nowhere near as much room left over as a 2K EEPROM provides. It may or may not be practical to use this extender depending on how much else you need to add to it.

Due to these space limitations, the special protocols are not pre-loaded as is the case with other extenders, but I've provided upgrades in the text files describing each protocol so that you can add them in IR.

Also, please note that the unextended URC-6131 uses a newer keymove format. The extender uses the normal keymove format, so you'll have to re-create any existing keymoves.

Thanks Mike. I'm sure this will come in handy for people who got the factory upgrades. Myself, I have lots of 6131's and some of them are used in locations that don't need all the functions that the "Family Room" needs but still need to send complex commands. Now I can use some of those 1k eeproms left laying around after re-upgrading my first factory upgrades.
