Jottem,

Not sure which signals you are referring to when you say "datalink signal" on the SCART socket, if you mean the one way AVL on pin 8 which is also used to define automatic format it is as follows:-

Inactive Source 0V to 2Volts
4:3 format 9.5v to 12 volts
16:9 format 4.5 volts to 7 volts

If you are not talking about pin 8 of the SCART, please define which signal you are talking about.

I'm also looking for specs for the AVL signal (the one that controls a VCR or DVD via the SCART socket).

Can anybody help?

Regards Rasmus 

Hi Keith,

Yes, I mean Pin 8; so what is the level for high and low ??

thanks for your help.

Jottem,

If you put an scope on pin 8 you will see the actual "data" stream normally from a Beo4 command sitting above the voltage depending on what format has been set with a peak-to-peak value of about 1 volt.

So, if the format is currently set to 16:9 then there will be a constant voltage level between 4.5 and 7 volts and it normally it sits around 6 volts but varies by many factors including cable length. On top of the six volts will be the "data" stream. So in this example with the format voltage at 6 volts then the data stream will be between 6 & 7 volts.
