[QUOTE="druden, post: 32129, member: 17670"] Hi, I'm working on a Beo4 IR remote receiver (used with Bang & Olufsen equipment). I've built the simple Lirc (WinLirc) receiver [url]http://lnx.manoweb.com/lirc/?partType=section&partName=circuit[/url] with a single mod: the IR receiver (which is typically based on the Vishay TSOP1738 or equivalent) is replaced by the TSOP7000 - because B&O uses 455 kHz as carrier frequency - it allows for signal strengths 10x that of other IR remotes. So far, it looks promising. I downloaded WinLirc, and I can grab raw data from my Beo4. From this I can see the pulse and space lenghts when I press random buttons. However, I can't get WinLirc to "learn" remote commands, it simply says it can't get a consistent signal. Other people seems to buy a pretty expensive box from IRtrans or Lintronic. I prefer the homebrew solution because it covers all my needs, and it will be almost invisible in my living room compared to other solutions. Anyone has experience with Beo4 (or Beolink 1000 which afaik uses the same freq and signalling scheme)? [/QUOTE]
