S2C M 48/78
Underwater Acoustic Modem
The S2C M 48/78 underwater acoustic modems with a horizontally omnidirectional transducer beam pattern are high-speed devices for effective transmissions in reverberant shallow waters, providing data transfer rates up to 31.2 kbit/s over a 1000 m range.
The beam pattern is optimal for horizontal transfers.
The S2C M series of "mini-modems", a product line designed for size- and weight-sensitive applications, is ideal for integration with modern UUVs.
Applications include:
-
Communication and positioning for AUVs and ROVs
-
Diver tracking systems
-
Size- and weight-sensitive applications
-
High-speed communication in adverse conditions
High-Speed
High frequency device for fast data transfers
Light and compact
Smaller and lighter build designed for size- and weight-sensitive applications
Directivity pattern
The beam pattern is optimal for transmissions in horizontal channels

1) One RS-232 Interface can be replaced with a RS-422 interface. Contact EvoLogics for more information!
2) Power consumption for RS-232 interface. Add 500 mW if an Ethernet interface is installed. Add 300 mW if the Wake-Up Module is installed. User-configurable Listen Mode is only available with a Wake-Up module installed. Power consumption in Listen Mode depends on Listen Mode settings.
3) Contact EvoLogics for more information on external and internal power supply options.
4) Dimensions of a Delrin housing, other builds are slightly larger.
5) The Wake Up Module is only compatible with RS-232 interface! It is not compatible with Ethernet or RS-422.
