If you have a with your NCT-196N, or if you need to know about its interfacing capabilities with other bridge equipment,

Pros:

The internal architecture features an independent, automated double-superheterodyne watchkeeping receiver. This ensures continuous background scanning across all 6 global distress frequencies simultaneously: 2187.5, 4207.5, 6312, 8414.5, 12577, and 16804.5 kHz.

The JRC NCT-196N is not a typical modem; it is the certified core of modern ship communication—a specialized modem that integrates and NBDP (Narrow Band Direct Printing) capabilities, and serves as a dedicated watchkeeping receiver . Understanding its operation is essential for both maritime safety and GMDSS compliance. This guide will serve as the manual you need, breaking down everything from basic functions to advanced programming.
