S2C M 15/27
Underwater Acoustic Modem
The S2C M 15/27 underwater acoustic modems with a wide-angle (120 degrees) transducer beam pattern are depth-rated devices for medium- and long-range transmissions, providing data transfer rates of up to 9.2 kbit/s over 3500+ m distance.
The wide-angle transducer beam pattern (120 degrees) is suitable for numerous applications, enabling vertical and slant transfers between mobile and/or stationary nodes.
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
-
Size- and weight-sensitive applications
-
Effective communication in adverse conditions
Depth rated
Depth rated device for long-range 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 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] 300 VDC available for 42/65 models. Contact EvoLogics for more information on power supply options!
[4] 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.
[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.
