I have learned a Teac TV command on my Pronto TSU7000 but when I execute the command it does not work!

What could be wrong?

Here is the command I learned (AV input)
0000 006C 0000 000C 0020 0020 0041 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0041 0041 0020 0020 0041 0020 0CCD # AV

Try this version

5000 0000 0000 0001 0000 0009

John,
is that a converted version of the command that the colonel supplied?

if it is, how come the remote doesn't convert it? I had trouble keeping the remote from converting copied and pasted commands into short ones like you gave...that did not work.

Unless I made a mistake it is.


I don't know the remote's rules for deciding whether to convert codes like that. I'm also a little surprised it didn't convert automatically.

I think the learned signal was good enough that converting it should only fix the toggle bit. Without fixing that the problems should be subtle, rather than "does not work!" as described above. But I think the 5000 form is worth trying, even though I can't explain how all those details apply in this case.

Well, seems like I have made a small progress.

The code 5000 0000 0000 0001 0000 0009 switches the input to "tuner" (I have 2 buttons - AV input or tuner input) not the AV. BTW the TV model is TEAC CT-M631S.

But at least I know that this command does something. I tried changing the 0009 to see if I stumble on the AV input but it didn't work.

Does it mean that this is some kind of a toggle command?

Is there somewhere I could find how to translate the long commands to these shorter ones?

To translate the signal, I used the JP1 group's modified version of IrTool.exe and by DecodeIr.dll
[Link: remotecentral.com]
[Link: john.fine.home.comcast.net]

That decodes as RC5 protocol, device 0, command 9.

I manually reencoded the condensed form:
5000 0000 0000 0001 0000 means RC5 protocol, device 0.
The last part 0009 is the command number translated from decimal to hex (which doesn't change 9, but would change higher numbers).

I searched my set of downloaded CCF files for TV's using the command RC5:0:9. There are lots of them, but that command is almost always the digit 9. Where it isn't the digit 9, it was hard for me to tell what it is intended to be. For example in the Loewe Arcadia 84 TV in this ccf:
[Link: remotecentral.com]

that command seems to be part of some sequence that turns the TV on and selects AV1. But I really can't tell whether I'm interpreting the ccf correctly.

I also looked specifically for Teac TV's using RC5 and found only this LIRC file:
[Link: lirc.sourceforge.net]

In that file, the last two digits of each command line are the command number in hex. Notice that command 09 is the digit 9 as with almost all other TV's using this code set.

Are you sure your TV really has discrete select commands for Tuner or AV?

Maybe the digit keys switch to tuner if it wasn't already on tuner. The remote you learned from might have a macro built-in that sends a 9 digit to switch to tuner then sends the AV/Tuner toggle command. That combination would work as a discrete AV select, but if you tried to learn it the Pronto would learn just the first step of the macro.

If that is the case, you can build a similar macro yourself.

Thank you very much for the info.
Using that I was able to work out that the TV command is the same but has F instead of 9 at the end.


I am not sure at all and I guess that is my problem. I have 2 buttons, one that switches from TV to AV and the other one does the reverse. Pressing the same button repeatedly does nothing other than pops up a text on the screen that either says 'AV' or the current channel number.


I am not sure about this. The remote is quite a simple one that came with the TV. I wouldn't think it is capable of macros but you could be right that it may send a sequence of commands.

So far I have discovered this:

Option 1) TV in the TV mode:
both 5000 0000 0000 0001 0000 0009 and 5000 0000 0000 0001 0000 000F do nothing but pop up the current TV channel number on the screen. The '0009' command also swithces the channel to channel 9 if it wasn't there already.

Option 2) TV in the AV mode:
both commands do nothing else but show a 'AV' message on the screen.

Repeating the same command does the same each time (displays a message but no selection change)

I feel that I am very close but I am also getting more confused. Is there anything else I could try? I tried sending the 9 followed by 15 but I got the 'AV' popup and nothing else.

BTW 5000 0000 0000 0001 0000 0009 is actually also the same as the CH 9 button.

With nothing to lose I started experimenting and went through the entire range (changing the last bit).

I have discovered that:
AV input is -> 5000 0000 0000 0001 0000 0038
TV input is -> 5000 0000 0000 0001 0000 003F

So I am not sure how my Pronto came up with those other commands. I am glad it works now.

Thank you everyone!
