Technical characteristics


        Complies with all international rules and regulations promulgated by ETSI (European Telecommunications Standards Institute), IEC (International Electrotechnical Commission), ITU (International Telecommunications Union) and IMO (International Maritime Organization), as well as national legislation.


        SAILOR RT4822 VHF DSC is ideal for use in maritime transport. It is an instrument DSC (Class A) which has all the necessary components in a small package size, which makes it very convenient for installation on board ships where the internal space is very limited.

        The basic configuration of the radio SAILOR RT4822 includes a transceiver and handset telephony. Interface SPARC, Ah interface and balanced data are used to connect multiple devices control and external control of the computerized devices / software. Maximum length of the connecting cable between the transceiver and the tube depends on the voltage in power supplies: 40m at 12V DC and 80m at 24V DC.

        Main unit VHF Sailor consists of a receiver, transmitter and speaker power 4W. There is also an audio amplifier to connect an optional 6-watt speaker. Rated voltage at the power supply station must be 12V DC. With devices SAILOR N163S and / or N420, the system can be powered by AC or DC power with 24V.

        Additional connector transceiver contains NMEA interface for connection to the ship's navigation system.
