Is there a way to make for example thess codes to a hex code and then make it to send the command longer ?

#1 5000 0000 0000 0001 0011 003F

#2 6000 0000 0000 0001 0004 003F

#3 5000 0000 0000 0001 001A 003F

#4 5000 0000 0000 0001 0000 003F

I need these for my macros to function properly, they are all inputs to my reciever. They worked flawless before I updated the firmware.

OK, no answers ....

I've seen that many get the hex code when they learn from the original remote, but all I get is the clean rc codes. Is there a way for me to see the the learned Hex code ?

You can use the MakeHex program to convert to 0000 format Pronto Hex.

The 5000 format is RC5 protocol. The 6000 format is RC6 protocol.

The 5'th number is the hex for what MakeHex calls "device", so that first one is hex 11, meaning device 17. The 6'th number is hex for what MakeHex calls "function", so they're all function 63.

There are many threads here on how to edit 0000 format hex to make it send longer. There are at least a couple threads on how to edit the .irp file so it generates the longer version directly (which may be less work than editing the Pronto hex after running MakeHex). Either way is subject to the same limits on the max size of Pronto Hex, and potentially the same glitches in PENG and/or the NG Pronto firmware in handling inter-frame gaps within Pronto Hex.

Thanks for explaining Makehex, but it was to no good, PENG changed it back to the 5000 code, or chaned the last 0cc4 bit to a 0020 bit so that doesn't work at all.

This is the code I got for
5000 0000 0000 0001 0011 003F:

0000 0073 000C 0000 0020 0020 0020 0040 0040 0020 0020 0020 0020 0040 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0CC4.

Edit:
Tried the paper trick and got this code that works but I still need to hold down the button for like 2 sec:
0000 006D 0001 000C 001F 0043 0043 0022 0022 0022 0022 0043 0022 0022 0022 0022 0022 0022 0022 0022 0022 0022 0022 0022 0022 0D55 0022 0022 0043 0040

Guess I'll have to wait for a new release of the firmware/PENG before it acts like it should.

Were you using MakeHex for any of that, and if so what version? Is the "paper trick" some way of forcing a bad learn?

I can't figure out what your first sample is supposed to be. It looks similar to an RC5 sample from MakeHex, but not close enough. When I use MakeHex for RC5 device 17, command 63 I get:

0000 0073 0000 000C 0020 0020 0040 0040 0040 0020 0020 0020 0020 0040 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0CA4

I know that PENG tends to recognise RC5 in 0000 form and translate it back to 5000 form. But it doesn't take much disguise to fool it. All the numbers after the first 4 are approximations, so changing them slightly won't bother the device receiving the signal, but may stop PENG from seeing the pattern. The big number on the end of each frame (call the "lead out") is especially safe to modify, so it may help to use a different lead out on each frame when extending a signal.

I just tried the correct 0000 signal in PENG and of course it converts it to 5000 form. Then I tried the same thing extended by one extra frame (without any disguise) and PENG didn't recognise it:

0000 0073 000C 000C 0020 0020 0040 0040 0040 0020 0020 0020 0020 0040 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0CA4 0020 0020 0040 0040 0040 0020 0020 0020 0020 0040 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0CA4

Extended to three frames (see below), it still doesn't recognise or change it. I don't know when the problem kicks in. Or maybe it's because of the version of PENG I'm using (Build Version 1.2.4.0). I assume you need more than 3 extra frames and I'm not sure where problems would start.

0000 0073 0024 000C 0020 0020 0040 0040 0040 0020 0020 0020 0020 0040 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0CA4 0020 0020 0040 0040 0040 0020 0020 0020 0020 0040 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0CA4 0020 0020 0040 0040 0040 0020 0020 0020 0020 0040 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0CA4 0020 0020 0040 0040 0040 0020 0020 0020 0020 0040 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0020 0CA4

Thanks for your help, but it seems that it doesn't work to extend the signal, I've tried with this and I still have to hold down the button to make it change:

The strange thing with this reciever is that two of the inputs I can use in macros so it works (the TV and Sat inputs). I don't understand how some work and others doesn't.

Thanks again for all your help though :)
