The DSC Receiver receives messages from external stations such as VTS. By means of the DSC
messages, specific settings such as a change of the VHF channels can be controlled.
The VHF transmitter/receiver has a limited range. By means of the connection of a long range commu-
nication system (such as a satellite communication system) to the long range port, this limitation can be
eliminated. In this way, the AIS can be called to send the ship’s data. The requested data are sent via
the long range port and the long range communication system to the questioner. The operator can decide
whether a long range request is answered or not. For further information, see the operating instructions
of the Display and Control Unit or the navigation system.
