S2C R 18/34 WiSE
Underwater Acoustic Modem
S2CR 18/34 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 18/34 WiSE modem with a horizontally omnidirectional transducer beam pattern is a universal tool for communication in reverberant shallow waters, providing data transfer rates up to 13.9 kbit/s over a 3500 m range.
The EvoLogics WiSE toolchain allows to build custom firmware modules for S2C modems and opens endless opportunities for new implementations.
High frequency device for fast data transfers
Firmware sandbox to run custom code
The beam pattern is optimal for transmissions in horizontal channels

 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.
 300 VDC available for 42/65 models. Contact EvoLogics for more information on power supply options!
 Dimensions of a Delrin housing, other builds are slightly larger. Dimensions vary depending on housing type and installed options.
Contact EvoLogics for more information on device dimensions and weights, request a drawing if necessary.
 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.
 The Power Switch is only compatible with RS-232 interface! It is not compatible with Ethernet or RS-422.
