S2C T 48/78

Underwater Acoustic Modem

The S2C T “tiny” modems are the new generation light and ultra-compact form factor that represents a size reduction of almost 20% compared to our M-series mini-modems.

The new model features a fully-fledged S2C engine and is compatible with R- and M-modems of the same type.

S2C T “tiny” modems deliver a great performance in most challenging conditions and offer several configuration options to meet the needs of a particular application. S2C T is a great fit for small AUVs and ROVs where seamless integration of hardware and software components is critical.

Applications include:

  • Fast short and medium range transmission in horizontal channels

  • Communication and positioning for AUVs and ROVs

  • Size- and weight-sensitive applications

  • Fast data transfers in adverse conditions 

High-Speed

High frequency device for fast data transfers

Ultra-light and compact

Smaller and lighter build designed for size- and weight-sensitive applications

Directivity pattern

The beam pattern is optimal for transmissions in vertical and slant 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. 2-interface Wake Up Module version reacts to incoming data on two serial interfaces.
6) The Power Switch is only compatible with RS-232 interface! It is not compatible with Ethernet or RS-422.
