I am hoping someone can explain how I can import the hunter douglas power rise up and down codes posted here in the pronto hex format into a MX-850. I have tried to follow other threads that say to convert it using the prontoedit program but I cant figure it out.

Try a search under my username regarding this...i've personally listed the procedure several times.

I found good directions but when I try to copy and past the IR code I get a ProntEdit message that says " Data does not define a valid IR code" The code I am copying is from here [Link: remotecentral.com]

Any help is appreciated.

Unfortunately that error message is correct.

Whoever posted those Pronto Hex strings did it wrong (probably didn't notice a scroll bar in the window they copied from) and truncated the strings. The posted strings are useless fragments of the originals they were copied from.

Did you try the CCF file at
[Link: remotecentral.com]

That has similar signals. I can't get a good look at them at the moment because I don't have ProntoEdit on this computer. But I'm sure they won't have the same problem as the ones you found.

With DecodeCCF I can see there are seven signals in the "blinds" device in that CCF file. Five of those signals are RC5 signals in a form Universal Browser can't understand. But the "UP" and "DOWN" signals (which seem to be what you want) are in the form Universal Browser understands.

BTW, you can use MakeHex and IRPanels.exe to get those RC5 signals into a CCF file in a form you can use. The five signals are RC5 device 17 functions 63, 31, 30, 33 and 32.

Thanks for the help. I finally have the blinds working. Just for my knowledge could you explain a little more about the RC5 signals? How do you know those five signals are not readable by universal? Thanks again.

I assume that means the "UP" and "DOWN" functions in that CCF file worked for you.


There are many different IR protocols (ways of encoding commands in IR signals). "RC5" is one of those protocols.

The "UP" and "DOWN" signals didn't look like RC5. But I'm not certain of that. It is strange that a device would have five commands in one IR protocol and two in another.

Do you know what those five commands do for the blinds? Apparently you didn't need those five commands?


Pronto Hex has a generic format for recording almost all types of IR signals, when its software doesn't recognize the specific protocol. So far as I know, the Universal Browser understands only that generic format.

Pronto Hex also has a bunch of different condensed formats for recording the several IR protocols that it can recognize. RC5 is one of the protocols it can recognize. Typically a clean learn of RC5 would be recognized and stored in the condensed form, while a worse learn of RC5 (that still might still be good enough to use) won't be recognized, so it would be stored in generic format.

My decodeCCF program gives info on each of the IR signals in a CCF file. It showed me that those five signals were RC5 in the condensed format (that I think Universal Browser doesn't understand) and the last two signals were in generic format and either are an IR protocol I've never seen before or are such bad learns that my software can't recognize it (My software recognizes most of the signals that Pronto software can't recognize).
