This is an authentic Furuno Electric DB-1 Distributor Unit, a crucial component for integrating marine electronic systems on vessels of all sizes. With serial number 2000, this unit is a proven and reliable interface device designed to ensure clean, stable data flow throughout your vessel’s navigation network.
Primary Function:
The DB-1 acts as a data buffer and distribution amplifier. It takes a single NMEA 0183 data signal (e.g., from a GPS receiver, gyrocompass, or AIS) and provides four identical, electrically isolated output streams. This prevents data conflicts, solves “talker overload” problems, and allows one critical data source to feed multiple display units, plotters, radars, or other devices simultaneously.
Key Features & Benefits:
-
1-IN, 4-OUT Design: Distributes one NMEA 0183 input to four independent outputs. Ideal for system expansion.
-
Signal Isolation & Buffering: Protects source equipment from backfeed or faults on connected devices. Ensures data integrity and system reliability.
-
Compatibility: The industry-standard NMEA 0183 protocol ensures compatibility with thousands of marine electronics from Furuno, Raymarine, Simrad, Garmin, and others.
-
Plug-and-Play Installation: Simple wiring and compact design for easy installation in consoles, bridge panels, or equipment racks.
-
Critical for System Integration: An essential tool for building a robust, fault-tolerant navigation network on fishing boats, workboats, yachts, and fast vessels.
-
Proven Furuno Reliability: Built to marine standards for durability in the harsh maritime environment.
