JP1 Remotes

Code: Format button long key press
1. Device: D* HR21-700
2. Type of device: D* HD DVR
3. Year:2007
4. JP1/UEI Remote model:URC9910
5. Do you have a JP1 cable? yes
6. Still have original remote? yes
7. Checked the file section? yes
8. Checked Pronto file section (at R/C)? No - don't know this one
9. Partially working setup code? sort of
10. Learning remote question? The HR21 uses the same KM file as the HR20. The HR20 file has several LKPs mapped but not the Format button. The function of the Format LKP is to turn Native mode on/off.

I haven't been able to learn these codes, I think because I don't know how to separate the RF signals from the IR signals.

I can't see how RF has anything to do with this. Please explain a little more about what you're talking about. You refer to the functions in question as LKPs. Are you talking about a long keypress on the JP1 remote, or on the OEM remote?

Are you sure that the OEM remote sends a different signals for a LONG vs a SHORT keypress? ...or is it just the box responds differently? Have you tried simply holding down the button on the JP1 remote corresponding to the SHORT function and seeing if the box responds to a SHORT keypress differently than to a LONG keypress?

If the DirecTV box responds differently to a LONG keypress of a particular button on the OEM remote than to a SHORT keypress, then you have to try to learn both the SHORT and the LONG version of that button. Even if the learns don't make sense to you, post the IR file with the learned signals to the diagnosis area and provide a link to it in this thread for somebody to take a look at the learns.

Lots of options and testing to do before somebody is likely to be able to come up with an answer for you.

I agree with Capn that it has nothing to do with IR versus RF.

kcorth is correct that at least the transport keys send different signals for long and short key presses. Both versions are in the KM file. However this doesn't appear to be the case with the format button. Like kcorth, I had no luck learning the long key press. But I tried a long key press with the OEM remote and my HR20 and it worked no differently than the short key press, which cycles through the different resoultions. So even if I could learn it, it wouldn't work.

Now the HR21 may be a different story, but on the HR20, native on/off is buried in the menus. So it just requires a rather long macro. Can anyone else with an HR21 can confirm or deny this long key press fomat native toggle, and if so, which OEM remote does it?

Edit: I saw in another forum that format long key press is supposed to toggle native on/off, but it sure isn't working for me. kcorth, does it work for you using the OEM remote?

Yes. Holding the Format button on the OEM remote turns native on/off. It's much nicer than digging through those menus.

All I meant is that I can't figure out the signals for the learned codes. IR is displaying different information than I'm used to seeing. Will have to post the file.

And yes, the OEM remote sends a different signal for LKP than short.

The learned signals for long and short leypress are the same. It is not sending a different code. Therefore this seems to suggest that it is the BOX that responds differently when the SAME signal is received for a "long" press, not that the remote is sending a differrent signal.

I asked before, and you have not answered, since you seem to have zeroed in on the "learning" problem.

Have you tried holding down the key to which you have assigned the OBC 115 command in your device upgrade on your JP1 remote to see if the box responds as if you were holding down the format button on the OEM remote? ... does the JP1 remote continue transmitting as long as you hold down the button, or does it merely send a short signal, regardless of how long you hold down the button?

If the latter is occurring, then you probably need an expert to re-write the Russound protocol, to continue transmitting as long as the button is held down.

If indeed I am all wrong and you are correct that the OEM remote sends a completely different command on a long press, then your learning has not shown ANY difference between the two. The only thing I can surmise is that on a long press of the OEM format button it INITIALLY sends the OBC 115 command and the JP1 learning is happy with its capture, but after a while, a DIFFERENT signal kicks in, but the JP1 remote is no longer "listening". You might want to try learning a different way to separate out these two consecutive possible signals, by not starting the JP1 learning until AFTER you have pressed and are holding the OEM format button. That may take a lot of trial and error to capture a unique second command from the OEM remote to start the learning at just the right time.

You were right, it does appear that the DVR acts differently to the LKP for that key. There was a setting on the DVR that was preventing it from turning Native on/off. Once I found that then the LKP on the JP1 remote worked correctly.


Thanks for your help.
