The key to this issue in my view in Carrier Frequency.

The Feller's XML file produced by B&O used a 36Khz carrier frequency which is correct for RC6 protocol.

The Beo5 and most IR signal converters have a Carrier Frequency range of between 30 and 80 Khz.

If Feller's uses a carrier frequency outside the 30 to 80 Khz carrier frequency range then the Beo5 will NOT be able to control it.

If you are willing to send me your original remote I will test it and give you a clear answer.

Hi Keith and mika,

It is most likely a problem of the carrier frequency. I also just found some indications, that they use 455kHz in this model.

Keith, it would be very useful for me you could analyze it. So, I would like to send you the remote. It is a very simple device with just 4 buttons.

Please send me you address, I might send it next week.

Just one simple questions: B&O uses 455kHz. Why does it not work to build a configuration, although Feller sends with the same carrier? Is this a propritary B&O frequency and cannot be used for 3rd parties?

Thanks,

Hangglider

Hangglider,

I have sent you my address by e-mail so you can send the remote.

Well, in principle you can from a hardware standpoint, but the protocol used by Feller will certainly be different to B&O

Hangglider,

I tried to send you an e-mail twice, but it gets rejected with the following error:-

"Recipient address rejected: User unknown in virtual alias table"

Hi Keith,

Sorry for that, I changed my email account few weeks ago and forgot to change it in my profile.

I just fixed it.

Thanks,

Hangglider,

Your Feller BeamIT remote arrived this morning.

I did a quick 10 minute review of it and I can see why Lintronic and everyone else has been having problems and also why the B&O supplied XML will never work and I guess it was not tested unless it is intended for a different Feller remote.

This remote appears to use an "Unmodulated" signal, in other words there is no carrier frequency which is a big problem for most receivers because the normal way of determining the "pulse" size is to count the carrier frequency periods which in this case cannot be done.

Tomorrow I will do further tests to see if I can come up with a solution to this issue.

Hi Keiths,

I feared, that this Feller remote is very speicific. I did another test with a Logitech Remote today. It is the model 895 with IR and RF transmitter. With this model I could setup the Feller and it worked. Maybe this could help you to find a solution.

Again, thank you very much for your work!

I have decoded your BeamIT remote and I can confirm it uses "Pulse Distance Encoding" using 80 micro second pulses with a typical pulse train of 13.5 milli-seconds

B&O remotes use the same type of encoding method, but the pulses are 270 micro seconds and the overall pulse train is about 140 milli seconds using a totally different protocol.

I have re-produced your BeamIT binary string on the Beo5 which works, but you will need to test it.

I will be sending you an XML file for test tomorrow.
