I have a Meritline 4x1 HDMI switch with audio.

I captured the signals from the remote, and 2 of them seem to have issues -

The power button has 2 protocols, and when I use the learned signal to turn the switch off, I can't toggle it back on again except with the original remote

The Mute button maps to a decode that IR can't understand.

I have posted the file in the Diagnosis area as:

I'd like both to work, but at fortunately these are the two least valuable keys (mute is on the TV and Receiver and this device stays on all the time).

Now to build the upgrade with the keys that work.

Could you do some more learning please.

Could you learn the POWER button to several different buttons on your 15-2116, then do the same for the MUTE button.

I'm looking for things that change between each learn.

Hi Andy,

Your Mute and your Power are just bad learns.

Code: Select all

1    TV    Stop_Eject        NEC1    0        24    E7    245        
2    TV    Play            NEC1    0        26    A7    247        
3    TV    Mute            NEC      0        2    BF    183        
            Gap-560-7891-13?     0        72            0.9    
4    TV    0                NEC     0        0    FF    181        
                            NEC1    0        0    FF    181        
5    TV    1                NEC1    0        8    EF    053        
6    TV    3                NEC1    0        12    CF    052        
7    TV    4                NEC1    0        14    8F    054        
8    TV    Up                NEC1    0        18    B7    119        
9    TV    Down            NEC1    0        16    F7    117        
10  TV    2                NEC1    0        10    AF    055

When the decoder reports NEC instead of NEC1 or NEC2 it just means that the key wasn't pressed long enough to capture a repeat frame so the type of NEC couldn't be determined.

In this case you can safely assume that the NEC protocols are NEC1.

For the power button, you pressed the power button two times during the learn. Apparently that will turn the TV on but won't power the tv off.

Thanks; I'll ignore the 'bad' learn and see what happens.

BTW, you guys are good at this

Please post a follow up to let us know if it worked out OK, and if it did please load a copy of your upgrade file.

If it didn't work, please post the additional learns that I requested.
