Wärtsilä SAM 4683 is a 2-axis doppler log and provides additional docking information by calculating the transversal speeds at bow and at stern. Information is displayed on a large, high resolution graphic LCD. Display graphics are continuously shown on the LCD along with complete navigation details. All IMO requirements are met or exceeded. Comprehensive interfaces are available including NMEA0183 input and output.
Transducer and Transceiver
Wärtsilä SAM 4683 transducer consists of a total of 3 hydro-acoustic 270 kHz elements for the 2 axis log function. The transducer can be connected to a transceiver electronics cabinet at distances up to 40m. The connection from the transceiver to the operator unit is via a serial RS-422 data link and may be up to 300 m. Transceiver power supply options are 230 V AC or 24 V DC. The power consumption is approximately 80 Watts at 115 / 230 V AC or 60 Watts at 24 V DC.
The operator unit contains a graphic dot-matrix color TFT LCD display and a keyboard with fixed keys, softkeys and a rotating encoder. The function of each softkey button depends on the active screen, and the buttons are labelled on the lower rim of the LCD. The display is backlit, and backlight intensity can be adjusted by the user. Various user-selectable information layouts, adapted to typical operational situations, can be displayed continuously on the LCD screen. The operator unit is normally flush mounted. Brackets for bulkhead mounting are available optionally. Operator unit power supply options are 230 V AC or 24 V DC. The power consumption is approximately 70 Watts at 115 / 230 V AC or 50 Watts at 24 V DC.
