S2C M HS
Underwater Acoustic Modem
The high-speed mini-modem offers incredible 62.5 kbps for short-range transmissions over 300 m range.
The omnidirectional beam pattern coupled with the compact and lightweight design makes it a great solution for integration with UUVs and diver tracking systems.
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
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.
