cNODE Modem MiniS

cNODE MiniS modem

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.

One cNODE® MiniS Modem can address several other cNODE® Modems during operation using the KONGSBERG Link User Protocol. The data telemetry operates on CYMBAL, KONGSBERG's field proven and robust proprietary link. Data rates of up to 6 kb/s are available. The cNODE® MiniS Modem is simple to configure with the TTC Light software.

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