JP1 Remotes

I'm diving in with two feet and hoping there is water. I play with electronics all the time, so this is my latest time killer

I have an OFA 8910, well, two of them (Amazon had a sale with free shipping, what can I say I'm a sucker). It hooks up fine to my new JP1 cable and responds great to the IR program; I can see all my learning attempts. However, in the list of remotes, two listings appear for this series of remotes. One with and one without "Extender 1". I thought this might refer to the eeprom upgrades that people appear to be doing to these; 2MB instead of 1MB. I just wanted to get some official confirmation or correction.

Can someone please fill me in on the meaning of "Extender 1".

Thanks in advance for any input!

Finally got a chance to search all of the Download area. Found the extender descriptions.

Your basic initial EEPROM image will use the non-extender rdf. In fact, when you downloaded from the remote into IR, this rdf should have been automatically selected by the IR.exe program. For SOME remotes, like the 6131, there are no EEPROM versions (out-of-the-box), 1K EEPROM versions (usually resulting from sending it in to OFA for an upgrade) and 2K EEPROM versions (usually when the mod is done by a JP1 hacker). I believe the 8811 has multiple EEPROM versions as well, up to 8K or so, (all due to creative hackers) but the usual EEPROM we encounter and deal with is a 2K. The 8910 has only a 2K EEPROM and no other variants.

The extender is a software install into the remote that basically takes over a great deal of its functioning from the ROM and allows you do many other "non-preprogrammed" stuff with it, like install special protocols for ToadTog (simulating discrete functions for normally toggled functions - or vice-versa), faster execution of macros (MUCH faster), unlimited (using nesting) length macros, define keysets slightly differently, etc. Because the extender so dramatically alters your remote's behaviour, separate rdfs have been written to accomodate this behaviour.

There is a separate readme file package with the extender zip file you need to download and digest. It's located in the Filie>extenders section.

I highly recommend using an extender, as amongst the extender's GREATEST features is the remapping of the EEPROM memory so that although you lose the ability to use learned signals, most of the learning memory is converted to Keymove/Macro memory, so you have MUCH more flexibility to customize your configuarion (and since the extnder is really just uploading an EEPROM image (along with your upgrades, etc.) it's a simple matter to save this image, reset your remote, learn and decode any new signals you need to, then re-load your IR image back, so you really lose nothing.

Good luck.
