Decoder DV-01 is designed to give individual subscribers the possibility to view TV channels, which are scrambled by coders of the Conditional Access System "Crypton". Decoder is used in cordless systems of microwave range ("TPC-Trophy", "MITRIS"). Decoder DV-01 works with a full format of coded radio signal.
    Constructively subscriber decoder is made as a radio-electronic module in a shielding casing of polypropylene with dimensions 55*35*20 mm. It is connected to the output "Decoder" of standard satellite analog receiver. The base of the decoder is MICROCHIP microcontroller. During programming every microcontroller gets individual number and blocking of the possibility of the following reading of the recorded information is implemented, what prevents from not allowed replication of the subscriber decoder.
    Decoder power supply with voltage 13-20V, current 35 mA is fulfilled from receiving converter power supply through the special adapter.
    Decoder has to provide capacity for work by ambient temperature from +1°С to +40°С, atmosphere pressure 630-800 mercury mm and relative humidity not more than 80% by 25°С.
