Question about EEPROM size and URC-8811

I purchased a URC-8811 remote and have a question. I'm not sure of the size of the EEPROM. Is there a easy way to know? In IR, the possibilities are:

URC-881x_801x_601x (6_806_80)
URC-881x_801x_601x 1k (6_806_80)
URC-881x_801x_601x x2 2k (6_80_2x2)
URC-881x_801x_601x x3 2k (6_80_2x3)
URC-881x_801x_601x x3 8k$1815 (6x80x8x3)

I've seen that people say the normal unmodified 8811 is 2k? is that right? Is the first in the list 2k and the 3rd and 4th for use with an extender?

I don't know about the basic RDF, but the last three are definitely for use with extenders. Just open an instance of IR nad use the "File>New..." and select each in turn. The memory bars at the bottom of the IR panel will tell you the total memory in each.

Having just done that, it looks like that first one is for the 2K EEPROM.

When you download from the remote using IR, it should automatically pick the correct RDF for your remote, as long as you downloaded and unzipped all RDFs. Is this not happening? Is it asking you to make a selection?

But to answer your question, apart from 1 or 2 URC-8811 remotes where the user changed the EEPROM, all URC-8811s have a 2k EEPROM installed.

The different RDFs are there to support the URC-6011 and URC-8011 which ship without an EEPROM, and may have had EEPROMs of different sizes added.

Ok, thanks. Unless I want to use a extender, I would just use the first choice.

Ive come up with a few additional questions, but I want to play around and try to figure them out first (and they would be better in another thread anyway).

Thanks again everyone for the help!

My point is...

a) you should always save all the RDFs, not just the ones that you think you'll need, and
b) when you download from the remote for the first time, IR will pick the right RDF, then once you know which one it's using, you'll know which extender version to use in the future.
