How can a decoder be connected to a satellite receiver in a communal installation?
Both SAT100 and Star2000 units are able to obtain the audio and video signals of the tuned channel in their corresponding connectors.
In a normal situation, without a decoder, these audio/video outputs are internally bridged to the modulator audio/video inputs.
To open this bridge a +12 Vdc voltage must be inserted into the corresponding connector pin:
SAT100 pin 6
Star2000: pin 3
There are some decoders that provide this "switching voltage" .
If you do not know which decoder generates this tension, Televes has prepared some special leads that provide a connection between the decoder and the corresponding unit, and that have internal circuitry to open the loop.
These decoder leads are:
