cNODE - Modem MiniS

The cNODE® MiniS Modem is designed for the Point 2 Point transfer of data between two cNODE's or to a surface vessel equipped with any HiPAP® and μPAP® systems. The data telemetry operates on CYMBAL digital protocols, KONGSBERG field proven robust propriety link.

The cNODE® housing rated for 4000 m is manufactured in coated anodised aluminium. Transducer options include an 180° omni directional and 40° vertical transducer to ensure the link can be optimised based on water depth and environment.
