S2C R 48/78 WiSE

Underwater Acoustic Modem

S2CR 48/78 White Line Science Edition (WiSE) underwater acoustic modem provides extra features for developers: it has an embedded firmware sandbox.


This open environment for network protocol developers offers a flexible framework for testing new network protocols: the sandbox eliminates the need to interface each node of the test network to a dedicated PC for running code. Scripts and other programs can be run directly on the WiSE underwater acoustic modem - on real hardware in real-world conditions.


The S2CR 48/78 WiSE modem with a horizontally omnidirectional transducer beam pattern is a high-speed device for communication in reverberant shallow waters, providing data transfer rates up to 31.2 kbit/s over a 1000 m range. High operating frequency ensures great performance even in noisy environments.


The EvoLogics WiSE toolchain allows to build custom firmware modules for S2C modems and opens endless opportunities for new implementations.

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.
