The JRC NDF-369 is a commercial marine terminal keyboard manufactured by Japan Radio Co., Ltd. (JRC) in Japan. Specifically engineered as the primary user input terminal for JRC JUE-85, JUE-85C, and JUE-87 Inmarsat-C Mobile Earth Stations (MES), the NDF-369 enables bridge officers to compose, edit, and transmit GMDSS telex messages, distress alerts, and Maritime Safety Information (MSI) reports.

Built into a compact, splash-resistant chassis, the NDF-369 features a standard QWERTY key arrangement augmented by dedicated GMDSS and terminal command function keys. It utilizes tactile membrane key switches designed for high reliability under continuous vibration, providing precise keystroke registration on chartroom desks and integrated satellite communication consoles.

Key Features:
• Dedicated Inmarsat-C Interface: Purpose-built for seamless integration with JRC JUE-85 / JUE-85C terminal processing units and display monitors.
• GMDSS Command Keys: Includes quick-access function keys mapped to Inmarsat-C message editing, distress alert handling, and system status menus.
• Compact Marine Footprint: Reduced-size profile designed to fit snugly on space-constrained bridge desks, slide-out drawers, and GMDSS consoles.
• Tactile Membrane Switches: Spill- and dust-resistant key assembly with clear tactile feedback for error-free typing during rough sea conditions.
• Industrial Vibration Resistance: Built to pass stringent marine environmental standards (IEC 60945) for long-term reliability on commercial vessels.
