RCA RT2600 audio receiver

Capn Trips · Post by **Capn Trips** » Mon Feb 06, 2006 8:08 am

Let me try to piece this together, as it's difficult to follow what you have done/are attempting to do:

(1) You have an RCA RT2600 Audio Receiver you wish to control with a universal remote;
(2) You have a RS 15-1994 JP1 remote;
(3) You have located an upgrade for an RCA RT2300 that you hope may serve as a basis for your RT2600 upgrade.
(4) You have modified this RT2300 upgrade in some way (this is where it gets unclear to me) changing the protocol (?WHY??

) and device number

You will have better luck at getting useful help if
(1) You write complete sentences with punctuation;
(2) you provide specific details (what field on what tab or worksheet of what program did you do this in:

I had to change the protocol name to RCA
and the device code to 68

and why?)
(3) You provide links to the files to which you refer (it's really painful to search through the file area for a file to which you MAY be referring), and upload to the diagnosis area, and provide links to, any files you have created that are giving you difficulty (it's even HARDER to reproduce the exact sequence of changes you're trying to describe in a file to troubleshoot).

BOTTOM LINE:
To be frank, you'd be MUCH better off just using the 1994 to learn all of the functions you want, decode them, and then creating an upgrade from scratch. Then you KNOW you have the correct protocol/device information in your upgrade, and you're not relying on someone else's button layout or possible mislabelings or whatever.

Just my opinion.

OK, having hunted about and looked at some RCA files, I see that RCA receivers are a bit different, in that all of the "normal" receiver functions are organized pretty normally, as RCA protocol, device 12 functions, but the input select commands all use a different device number, but the same EFC/OBC - which doubles as a "Power On" for corresponding RCA devices, as well as the input select command on compatible RCA receivers, amps, and TVs.

The file you chose to start from uses the bulky "Device Combiner" protocol, which in this case is a very awkward way (but probably back when the user created it, the only way) to combine the multiple device numbers required to cover all of these input functions.

What you REALLY require the "RCA Combo(official)" protocol, rather than the "RCA" protocol you selected.

I would recommend you use THIS FILE as your starting point, as it uses the correct protocol, and has all of the likely necessary functions clearly defined, and just by coincidence happens to be already formatted for the 1994.

P.S. I still cannot see any possible reason for you to have changed the device code to 68, however, as that is not one of the device codes for ANY of the functions, and I have only ever seen RCA protocol using low numbers, ranging between 4 and 15, or so.

Thanks capn trips,

I will try to be as descriptive as I can in the future.

When I loaded the Rt2300 file to KM for some reason it prompted me to change the protocol name as well as the device code.I am unsure why it prompted me to do so.I did the changes to RCA and 68 then copied and went to ir.exe,added new device then loaded to the 15-1994.The code was accepted.I tried the remote on the RCA RT2600 and got some functionality with it.However many of the keys moves did not work,I assume thats due to the fact that I changed the device and code.

Later last night I tried the file in your link.KM prompted that the protocol code was also required for that file.The first time I tried the file I didn't realize that there was more code to be added below the device upgrade code.The first time I tried it didn't work,for obvious reasons.I went back and started over and then figured out that the protocol hex code also had to be copied to ir.exe.I copied both device and protocol to ir.exe,then I added new device and new protocol.Next I checked the code to make sure it was listed in ir.exe,it was.I then loaded it to the remote.Now I have a much better control with the Rt2600!

The particular receiver I have is a Dolby Digital audio device with many inputs.

It has dvd anl,dvdcoax,dvd optical 1 and 2,dvd 6channel
the other inputs have the same excluding the 6 channel

tv
sat
vcr
aux
tuner
cd
tape

It also has many settings such as..
Level control for all 6 speakers
Dolby Digital,Dolby Pro Logic 1,2
EQ settings
Tuner FM,AM presets etc
Source which is settings such as Theater Arena Stadium
Sleep Timer

So its pretty complex,as of right now the code in your link is the closest I have gotten.I would still very much like to get control of the other functions,but w/out an orginal remote I know its going to be difficult.I have a great deal of reading and learning to do!

Many Thanks to each of you that have been kind enough to lend thier expertise!!

I have loaded that file into KM and don't see any prompt to change the protocol (or anything else).

I am unsure why it prompted me to do so.

Me too!

That's not something KM does...

I did the changes to RCA and 68

How did you know to do this?

However many of the keys moves did not work,I assume thats due to the fact that I changed the device and code.

Changing the original upgrade file to a specific protocol/device number would break the key moves that use any of the other device numbers.

Later last night I tried the file in your link.KM prompted that the protocol code was also required for that file.

Is this the same prompt you referred to above?

The first time I tried the file I didn't realize that there was more code to be added below the device upgrade code.

The KM readme explains that, as well as many other details... have you read it?

I'm not trying to badger you with these questions. I just feel there's something you're not understanding in the whole process and want to be sure we have all the info we need to be able to help.

Without being able to explain as well as Capn.

It looks like you can get your missing sat input function by going to the function tab in km and adding the sat input function with obc=058 and byte2:dev=7

I don't feel like your badgering me at all!You have went out of your way trying to help and I certainly appreciate it!

Thanks for the tip whompus! I will try that!

Once again thanks for all the help to everyone. Patience isn't one of my better virtues

However determination is! I can't stand quitting!

OK, so now you have a partially working upgrade. We still cannot look at it, since you have not provided it for us to look at;

You still have not explained where you came with device number 68, nor convincingly explained how KM "prompted" you to change the protocol and device number;

If there remain inputs and other functions that are NOT mapped in the current device upgrade, LEARN THEM with your 1994, it is perhaps one of the most capable JP1 remotes out there, revered by some, and you are NOT using its capabilities to help you answer these questions.
After learning them, download the learns into IR.exe, use the notes functions of IR to correctly identify what function is learned where, and use the decode information yourself, or if you can't yet sort that out, upload the file and provide a link here, and we will help you get the rest of these functions identified and added to your upgrade.

I have loaded this KM file which contains all known codes for RCA receivers. I have also loaded this spreadsheet that lists the same codes in a tabulated form.

Apart from the input selects, you'll notice that all the tuner functions use device code 9 and all the amp functions use device code 12. Therefore, if there are still functions for your RT2600 that are not listed, you can try testing the gaps in the OBC sequence to see if they do anything.
