Hello,

I have an RCA Scenium set (D56W20), and was wondering if anyone has played around with the IR codes for it.

The remote has 4 input buttons (DVD, VCR, HD, and Sat/Cab) which are tied to inputs (Comp 1, Comp 2, DVI, Front, Video 1, Video 2, Tuner) via the TV set's menu/setup system.

The buttons work for switching from one input to another when the set is on, but they also seem to have a discrete power on command tied to them -- if the set is off and you push one, it turns the set on and tunes to the input.

Has anyone broken the IR codes for these inputs down into the discrete on and the individual input sections? Might one be able to do this?

Thanks,

Joe

RCA receivers, TV's, VCR's, etc. will switch AV inputs (and act as discrete input commands) when they get the discrete power on for the RCA version of a TV, DSS receiver, VCR, DVD, etc. The concept being, that one IR command turns everyting on. Philips typically does the same thing.

I would like to be sure that I understand you:

Are you saying that the four remote buttons, DVD, VCR, Cable/Sat, and HD send discrete on commands to RCA DVD Players, VCRs, Satellite Receivers, and HD Set top boxes, also are four seperate discrete on's for RCA TV's, and can be tied via the TV menu system to specific inputs on the TV? Talk about doing triple duty!

Should I expect the discrete on codes for RCA VCR's, DVD Players, Sat Receivers, and HD Receivers to be identical to the learned IR codes from my remote (and to turn the TV on to the assigned video inputs)?

Interestingly enough, the remote button for "TV" does NOT turn the television on -- however, the discrete code for RCA TV's does -- and also tunes it to the internal TV tuner.

Thanks,

Joe

It would be a lot simpler if you just posted the Pronto hex for the learned signals you're asking about. Maybe they are single commands that trigger multiple actions, or maybe they are macros in the original remote (buttons that send more than one command).

From other RCA devices we know that RCA has a standard discrete On command. When that command is encoded with the device number of the current device it typically justs turns the device on. When it is encoded with the device number of some other device, it may act as a discrete input select for the current device.

So a single command such as the discrete On for an RCA VCR may turn a VCR on and also select the VCR input on a receiver. I'm not sure whether it turns the receiver on as well.

Device 5, command 58.


Not copy/pasted correctly (incomplete copy of a bad learn), so I'd need a more careful examination to see what it is.


Really bad learn of device 7, command 58.


Too bad a learn to easily see what it is.


Device 15, command 58.

It seems these are all simple RCA discrete On commands (command 58) for various device numbers. They aren't macros. Whatever multiple actions may be triggered by one key are all triggered by the single command.

John,

How can I tell if a learn is bad/incomplete? The learned commands are good enough that they perform the same action as the original remote does. I'll try to learn something cleaner tonight.

How do you read the codes to get the Device and Command information? Is there a place where I can download or copy clean hex for these commands?


Thanks for your help!

Joe

The incomplete was not that it was learned incomplete. That happened during copy/paste. The text you pasted in this thread (for that one signal) was only part of the text from the View/Edit IR dialog in ProntoEdit. The scroll bar there (in ProntoEdit) can be confusing and it's an easy mistake to make.


Some pretty bad learns can still work.


The JP1 group has an enhanced version of the IrTool program that is used with my DecodeIR.dll to decode IR signals.

My MakeHex program can be used to generate clean signals. But since RCA discrete commands are so consistent across devices, I'm sure it isn't hard to find the full set of them posted in several places here at RC.

Here are the discrete on commands (and discrete input commands for RCA devices) generated with John's MakeHex. There are several with ?? that IIRC work for some gear. The rest should work and it may be easier to try them and see if they are what you need. The RCA DCT-100 commands (the RCA HD DSS receiver with OTA tuner) will also work for most functions since that tuner appears to be in most RCA HDTV's.

I edited in the full learned VCR code.

Thanks very much for explaining all this to me. I think I may have to download and try to figure out what the programs you reference do and how they work.

I'll try these codes tonight and see what they do (if anything). You are correct about the DCT-100 being internal to many RCA sets -- unfortunately my set is an HDTV monitor only (no ATSC tuner).

When I posted this thread this morning I had no idea I would get so much good info so quickly!

Take care,

Joe

It is device 14, command 58. The code Jon posted for VCR1 is a clean version of the same signal.

As you said they should, the discretes J. Armstron posted for DVD, VCR1, TV, and DSS (5, 14, 15, and 7) worked for the DVD, VCR, TV, and Sat/Cab buttons respectively.

However, I did not find one that corresponded to the Aux/HD button. I relearned it and copied it below. Can either of you tell me what this is and what the "clean" hex code is?

Thanks,

Joe

Looks like the batteries were too weak in the RCA remote to generate a signal the Pronto can learn. The actual RCA device has a better tuned IR receiver so it can still see the signal when it is too weak for the IR learning receiver in the Pronto to get it.

There is a little at the beginning of that bad learn that Jon or I might be able to use to deduce what the signal was. I may have time to try that later. But a clean learn with good batteries would be much easier.

Hi, John,

I'm afraid I have a 15 year old step daughter -- so I have NO new AA batteries in the house. I'll purchase some tonight. In the meantime, I popped the batteries out of one of my lightly-used remotes and recaptured the code for Aux/HD -- and repasted it above. Is it a cleaner signal?

I wasn't aware that new batteries were critical for capturing a good IR signal -- I thought if the remote was working, it was working. When I was setting up my system ccf, I had lots of back-and-fourth lern IR/test IR/re-learn IR -- I assuemd the system was flakey. Probably the batteries in my remotes were low. I may go back and relearn all my other learned remote codes with fresh batteries.

Thanks,

Joe

That is now a very clean learn.

You don't need brand new batteries in the sending remote to get a clean learn like that, just batteries that aren't nearly dead. Unfortunately, without a volt meter you might not know batteries are nearly dead when they still seem to work fine.

That signal is device 2, command 58.

The RCA protocol can encode device numbers from 0 to 15. I notice Jon posted device numbers 4 to 15. I'm sure he had good evidence from other sources that device numbers 0 to 3 wouldn't be used. In this case reality disagreed with whatever Jon must have deduced from other sources.
