The Macher MR-314 is a compact, space-saving wired mini keyboard manufactured by Macher. Specifically designed for commercial maritime satellite communication systems, the MR-314 is widely utilized as an input interface for Inmarsat-C, Mini-M, and GMDSS telex message terminals (including Sailor TT-3606E, Furuno Felcom, and JRC Sat-C systems) where navigation desk and bridge console space is strictly limited.

Featuring a reduced-footprint 88-key layout with an embedded numeric keypad accessible via Function (Fn) key combinations, the MR-314 utilizes durable rubber dome membrane switch technology to deliver quiet, positive tactile feedback during message drafting and system control. Housed in a splash-resistant, high-impact polymer chassis, it is built to resist continuous shipboard vibration and humidity on vessel chartroom desks and integrated bridge workstations.

Key Features:
• Space-Saving Mini Layout: Compact 88-key design tailored for tight bridge consoles, GMDSS communication desks, and slide-out equipment racks.
• Maritime Sat-C Compatibility: Engineered for direct integration with Inmarsat-C terminals, telex message processors, and marine workstations.
• Tactile Membrane Key Switches: High-reliability rubber dome switch mechanism provides quiet operation and clear tactile response on moving vessels.
• Integrated Numeric Functionality: Embedded 10-key numeric pad toggled easily via the Fn key for efficient coordinate and numerical data entry.
• Rugged Marine Construction: Built with durable, splash-resistant ABS housing designed to withstand shipboard vibration, shocks, and salt air exposure.
• Flexible Terminal Connection: Features a heavy-duty strain-relieved interface cable available with standard PS/2 or USB connectivity for marine transceivers and PCs.
