| | | EK60 Transceiver (GPT) • Frequency: 12, 18, 38, 70, 120, 200, 400, 710 kHz • High pressure transducers: 38, 120, 200 kHz • Power requirement: 10,5 to 14 Vdc or 110 to 230 Vac • Ping rate: Up to 40 s-1 • Range: 0 to 15000 m • Operating temperature: 0 to 55°C • Output power: 20 to 2000 W (frequency dependant) • Power consumption: typical 10-30 W • Pulse duration: 0,064 to 8,192 ms (frequency dependant) • Transceiver control: Up to seven (7) frequencies can be used simultaneously • Calibration: Easy-to-use built in calibration • Synchronization: Internal or external • Sensor input: MARINE GPS, Log-counter, Heave, Roll, Pitch, Trawl, Purse seine • Data output: Raw or processed data to user defined fil • Data subscription: Ethernet datagram based system fo remote subscription of data | | Wireless communication The echo sounder system consists of the transducer, the General Purpose Transceiver (GPT) and the Processor Unit (PC). Wireless communication can be introduced between the GPT and the PC, and/or between PC and PC. There is a trade-off between range and data transmit capacity of the link. You have many technologies to choose from. | | |
