Configurable underwater acoustic modems using EvoLogics’ proprietary S2C technology, with PRO, PRO USBL, MINI, TINY and OEM builds. Frequency and directivity choices change the range/rate tradeoff: current examples include PRO 7/17 at up to 6.9 kbit/s and 8000 m, PRO 18/34 at up to 13.9 kbit/s with an explicitly corrected approximate 2000 m field-average range, and TINY 120/180 at up to 62.5 kbit/s and 300 m. The figures describe vendor-stated performance under their stated conditions, not guaranteed application throughput. USBL variants add positioning; optional standards support and developer features must be specified per model.
Technical detail
Core features
PRO 7/17: 7–17 kHz, hemispherical coverage, housing-dependent depth up to 6000 m for titanium/OEM transducer.
PRO 18/34: 18–34 kHz; current range notice replaces older 3500 m near-ideal listing with approximately 2000 m realistic average.
TINY 120/180: 120–180 kHz short link, up to 62.5 kbit/s and 300 m; 200 m Delrin or 1500 m metal/OEM depth options.
Ethernet or RS-232 host interface; RS-422 is available by request on specified builds.
Prioritized instant messages can coexist with larger data transfers through the proprietary data-link layer.
Optional JANUS support is model/band dependent and is separate from native S2C operation.
Power depends on duty cycle and options: TINY lists 2.5 mW standby, 0.8 W receive and up to 11 W maximum output. The wake-up option is listed incompatible with Ethernet data interfaces; confirm the actual serial/power build.

Use & integration
Recorded applications
Telemetry from underwater instruments and fixed subsea stations.
Data exchange and positioning for underwater vehicles and other mobile assets.
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Commercially marketed modem family with public interfaces; EU WiMUST reporting documents modem integration into a bounded multi-vehicle sea demonstration.
Commercial availability
Current configurable catalogue through EvoLogics sales/distribution; actual model, options, price and delivery schedule require a quote.
