Hi Folks,

I'm looking for an XML for the REG 2 command of my special Beo4 remote to program it in the Beo5/6 remotes.

Now you may wonder what the REG 2 command does. Well, we use it to make the DVD (not the blu-ray) players of BeoVision 7 TVs region free for customers who ask for.

Tried to capture the command with the Lintronic TT455-RT-238 signal converter, but it didn't work, which is kind of surprising and somewhat disappointing for a product which is supposed to be universal and which gets the commands of any remote... but the B&O ones.

Any clues to get the REG 2 command into the Beo5/6?

Unfortuneately, like most IR receivers and converters, they use standard receiver diodes which generally only work with carrier frequencies between 20 and 80 Khz. B&O uses 455 Khz, hence why the Lintronics box could not capture the code. Also, because most capture devices need to count the carrier pulses means you need a fast micro proccessor in your capture device.

All is not lost, if we can establish the command HEX code, then a command can be added.

The best way to establish the HEX code is to put an PC type oscilloscope on the IR receiver in a B&O product and capture the screen shot which can then be decoded.

You should be able to receive B&O commands with the TT455-RT-238, if you connect an external receiver to it. Lintronic sells one and according to the pictures on their web site, it's a regular issue B&O hockey puck with perhaps a custom cable.

(I've never used these products myself, so don't really know much more than this.)

Yes, you are correct Mika, you can use an external PUC. I was talking about the internal IR receiver.

Right. Lintronic is selling a BO-sensitive IR receiver, but I was told by them that it doesn't allow to capture the signal.

Thanks Keith for your clear explanations. Well, I unfortunately don't have a PC oscilloscope. Just have the Lintronic device, which I thought would work.

Yes, I would expect that to be true because of the reason I highlighted earlier, the need for a fast micro processor to count the carrier pulses.

At 455Khz the pulse period would be one divided by 455000 which gives you a period of 2.1 micro seconds per pulse period, that is why the only real way is with an Oscilloscope.

Hi,

It's dependig which type of Lintronic box you have. The version 5 is able to capture B&O signal without external IR-Eye. HW6 needs an IR-Eye. You could try to use the log application of the lintronic configurator when capturing the signal and post the result. Maybe there's a way to analyze the command format of the REG 2 command.

Well, if hfat statement is correct about the version 5 box AND you have a version 5 Lintronic box, then we should be able to work out the hEX code of the command.

Hi,

If someone tells me how to send an REG2 command, I'll try to capture it.
