Description
DiveNET: Sealink series acoustic modems are highly compact, fully integrated devices offering advanced acoustic performance with scalable networking capabilities.
Sealink modems are supplied in two standard form factors: 64x62 mm and 41x45 mm. Additionally an integrated modem/USBL combo is available with dimensions 64х128 mm.
Standard maximum depth is 300 m with a built-in depth sensor, 400 m without a depth sensor and 1,000 m in OEM configuration with the modem electornics housed separately.
Sealink modems are powered by 5-12V.
Sealink modems are built for integration with UART-9600 and NMEA 0183 interfacing standards.
