I have a new Philips-LCD TV. From another forum I got discrete Codes for switching directly to AV1, AV2, HDMI1 ... The codes ar in a pronto format, for example RC5 3.04 switches directly to AV1. I use a MX500 as a universal remote and for discrete codes I have an Philips SBC RU 880 where I can input codes from 000 to 255. When this works, I copy the functions from the SBC to the MX500. So my question: Does anoybody know, how I can convert the pronto codes? Thanks a lot.

That's not really a "Pronto" format. It means RC5 protocol, system 3, command 4.

There is nothing specific to a Pronto about that way of specifying that TV signal.

I did confirm from several sources that is correct for the AV1 function.


I didn't know anything about the RU880, so I downloaded a pdf of its user manual.

In section 2.5.1 it describes using 3-digit codes from a table by brand. Is that what you mean by the "000 to 255"?

If so, there is no way to translate the discrete code info. Probably there is no way at all to get the RU880 to originate the signal you want. I think only OneForAll brand remotes and PC-programmable remotes can originate signals that weren't in their preprogrammed library.

If there is a way (that I didn't see in the documentation) to enter a 000 to 255 code, that seems to be the command code of a specific function (rather than an index into the built-in library), give more details. Maybe I might know how to make use of it.

Hello,
there's a method to program codes dirctly to the sbc
1 - pres an hold 1 nad buttons
2 - release the buttons
3 - enter the 3 digit code 000-255
4 - press the device key
5 - press the button
I tried this fpr my denon receiver and it worked. I did it with my tv (code 004), device tv (installed as 003) and button 1. When testing it, the key for program 4 was pressed, not for ext1.

Now it tried device 000 with code 057 for EXT2 and it worked. But the other codes don't seem to work. Unfortunately I have to check all codes form 000 to 255.

Is that explained in the pdf documentation, or somewhere else online?


It's too hard to guess which kind of number is which to understand what you said there.

There are three digit numbers that I think represent code sets (index into a library of protocol and system and key mappings).

There are other three digit numbers that represent individual commands.

I think what you said was you test command code 004 with code set 003 and the result was the same as pressing just the digit 4 of your original TV remote.

Digit 4 is command 004 in RC5 system number 0. So maybe code set 003 is system 0, or maybe you didn't really select code set 003, or maybe I misunderstood you entirely.


EXT2 is command 057 in system 0, so you seem to be able to send any command you want in system 0, but haven't yet found a way to send any command in system 3.

In RC5, there are just command number 000 through 127 in each system, not 000 through 255.

Adding 128 to a command code number might make no difference or it might select a different system number or it might send garbage. But anyway it should be easy enough to test.

128+4 is 132, so that should be a good one to test. If you're really luck it will be the command you want (system 3, command 4). If 132 acts just the same as 004, you'll at least know that is the way the RU880 behaves.


Not much point to that. If a given code set has command 004 sent in system 0, I'm sure at least all the other commands 000 through 127 will also be in system 0.

Hello,
the 003 code seems not to work. I tried different codes, nothing works. The addition ov 128 to code wasn't siccessfull too. I think I'll have to contact Philps.
