DiveNET: Sealink hydroacoustic modems are designed to provide robust, cost-effective and highly scalable underwater data transmission capabilities with extremely small space, weight, power and budget footprints.

 

The Sealink series includes four standard models: Sealink S, M, OEM, and USBL. All Sealink models are acoustically compatible and utilize a common pseudo-NMEA protocol for data interfacing with carrier systems.

​

Sealink modems can operate over 20 code channels with up to 254 devices per channel with standard transmission speeds of 78 - 634 bps to a maximum range of up to 3,000 m and depth of 1,000 m.

  • Extremely small size and weight​

  • Subscribers code division​

  • Operating range up to 1,000 m​

  • Shallow water reliability​

  • Low power consumption (Rx/Tx) 0.33/6 W​

  • Open configuration protocol​

  • Reliable data transmission with 78 bit/s​

  • Built-in depth/temperature sensor​

  • Propagation time measurement​

  • Can be applied in underwater wireless sensor networks
