Export a device from IR.exe?

I've been trying to see if I can export a single device from IR.exe as a .txt file so I can edit it using KM. Is there something I'm missing, or is it possible? Thanks in advance for your assistance.

That's not the way things work. You use KM (or RM) to create upgrades, or manipulate upgrades that others have saved as KM files. You use IR.exe to load those upgrades into your remote.

If you can see an upgrade in IR, how did it get there? Did you create it yourself, if so, did you save a KM file?

If what you're really trying to do is create a KM file based on a built in setup code that you're using, that's a different story. If you tell us what setup code you're looking for, one of us might be able to create a KM file for you.

I understand. For various reasons, I'd like to be able to tweak with the factory code for Receiver 110 on an 8910. None of the Harmon-Kardon codes that have been posted to the yahoo files really do what I'm looking for, so I was hoping to just start with the code that came with my 8910, and work forward, hence the desire to export from IR. If there's an easy way to extract that code into a .txt, I'd be forever grateful.

BTW, I've only been playing with this stuff for about a week, but so far, I'm very impressed with all of the knowledge being passed around here. Thanks to all of you experts!

JP1 only reads and writes the EEPROM, not the ROM.

If you want the EFC of an individual key from a built in setup code, you can KeyMove that key to another key, or (I prefer) to the same key of another device mode. Then download to IR and look at the KeyMove. That method would get quite tedious if you want a whole built in setup code. And you still need some way to get the basic characteristics (In this case NEC1, device 128, subdevice 112). Decoding a learned signal from the original device is the only good alternative for that (other than asking an expert).

If you want a good list of functions for a device, it's usually easier to get that from some CCF file for a related device, rather than try to reverse engineer the built-in setup code.

There are several CCF files for Harman/Kardon at RC. I think they all use pretty much the same commands, though I am a little confused by the relationship amoung Receiver/CD/DVD. The CD's seem to use NEC1:128.112 and the DVD's seem to use NEC1:130.114, but the receivers seem to use a mix of both of those. I usually can't tell whether that sort of thing means that a receiver really does use that mix or means that the creator of the CCF file also had the associated DVD and didn't make clear in the CCF file that DVD commands were mixed with the receiver commands.

If the receiver does really use a few NEC1:130.114 commands, that points out another advantage of using CCF files. The RCVR/0110 setup code is a simple NEC1 setup code (just 128.112, not a combo) so it can't support any of the 130.114 commands. If you focused on RCVR/0110 you could miss such commands.

If you still want just the basic RCVR/0110, here it is: HK-RCVR-0110.txt

I will agree that the HK codes seem to be more confusing then any others. Rob, thanks for getting me that HK110, I think I'm going to start there and see what I can come up with. Thanks for your explanations guys.
