Hi everyone,

I might not have worded this well from the topic but I'm trying to map the whole remote for my STB (Illico from Videotron in Québec, the STB is a Cisco but I can`t find the remote brand or model anywhere).

Anyways, I've captured all the codes with my HTC one M8 using Moletag's app. However, here is an example of the codes I got:

58252,189,196,47,149,47,148,47,49,48,148,47,149,47,49,48,49,48,148,47,148,47,49,48,149,47,49,48,49,48,148,47,49,48,49,48,148,47,149,47,49,48,49,48,148,47,49,48,2198,191,196,47,148,47,149,47,49,48,148,47,148,47,49,48,49,48,149,47,148,47,49,48,148,47,49,48,49,48,149,47,49,48,49,48,148,47,148,47,49,48,49,48,149,47,49,48,2197,191,196,47,148,47,148,47,50,47,149,47,148,47,49,48,49,48,148,47,149,47,49,48,148,47,49,48,49,48,148,47,49,48,49,48,149,47,148,47,49,48,49,48,148,47,49,48,2198

It looks like decimal code, I'd like to convert those to pronto in order to use it with unifiedremote.

Anybody can help?

Thanks!

The 58252 is the modulation frequency in Hz.  The following numbers are the duration of On, Off, On,Off..... in units of one modulation period= 1/58000 = 17uSec.    There are three instances of the same signal--each one ending in 2197 or 2198.
The pattern show lots of 48 and 149,  and the sequence  starts with 189/191, 196. So this is the typical IR signal. We can represent this signal as having durations of 4, 3, or 1 in units of 49 modulation periods. Assume that the the first 4,4 (191/196) is the leadin, and the following 22 burst pairs as the signal, and the signal is
leadin,11011 001101 00100 110010
I've grouped the bits in this way to illustrate a pattern:  11011 is the binary complement of 00100 and 001101 is the complement of 110010.

We know that this is characteristic of the IR protocol referred to as Panasonic (old), and it is used in Scientific Atlanta cable boxes.  Scientific Atlanta was bought by Cisco a few years ago.

Use the Hex codes for one of these cable boxes.

BTW, please edit your post to put in some <return> characters so that the post doesn't look so wide.

IrScrutinizer can digest this form directly:

Select Import -> Text -> Raw. Then select there: name column - (or 1), raw signal col. 2, select "and subseq. columns, select , (comma) as field separator. Copy the the signal from posting, and click "load from clipboard". It is identified as Panasonic_Old, D=27, F=44. (Although we just ignored the modulation frequency.)
