S9 - Ulti-modem Underwater Inductive Modem

The Ulti-modem enables ADCPs, CTDs, biogeochemical sensors, multi-parameter sondes, or other instruments having an RS-232 interface to communicate with moorings or platforms, or directly to shore using inductive telemetry. Data is transmitted using plastic-jacketed steel wire rope as the transmission medium, consuming very little power and eliminating failure prone underwater connectors and cables. S9’s innovative dual-mode technology provides fast transmit capability (up to 19200 baud) when communicating with other S9 Ulti-modems, and also communicates with inductive modem products from Sea-Bird Electronics. The plastic housing with titanium face plate is rated to 1000 meters depth. Typical battery endurance is three years.
