The Japan Radio Company (JRC) NCT-196N is a foundational component of modern maritime communications, serving as a dedicated Digital Selective Calling (DSC) and Narrow-Band Direct-Printing (NBDP) terminal. Built to comply with Global Maritime Distress and Safety System (GMDSS) requirements, this unit ensures vessels maintain reliable automated watchkeeping and telex communications.

While this guide provides a detailed overview, the official documentation is indispensable. The primary covers all standard operation procedures. For deeper technical work, the JSS-296 Service Manual provides internal details like printed circuit board (PCB) identification, component-level descriptions, and advanced troubleshooting for the NCT-196N. These documents are searchable online via model number.

Dedicated tactile keys for rapid distress activation and messaging.

The rear panel of the NCT-196N features several critical ports outlined in the manual:

: Contains internal non-volatile memory to log distress alerts, received messages, and transmission histories. 2. Hardware Interface and Connections

Connect the dedicated interface cable from the MES port on the rear of the NCT-196N to the DTE port on the Inmarsat-C transceiver.

Initial bench setups or hardware board replacements require explicit physical configuration of the internal . Adjustments require opening the main enclosure casing. Line Input Level (Short Plug ST1)
