Technical Specification

General:

• Function: Cable connection and distribution point for Furuno Satellite Compass systems (SC-series) or Inmarsat-C terminals (FELCOM series).
• Purpose: Simplifies wiring, provides organized connection for power and data signals.

Electrical/Connectivity:

• Input Ports:
  • Typically, one dedicated input for the main antenna cable (from the SC-series antenna unit or FELCOM terminal unit).
  • Power input connection (likely 12-24 VDC, derived from the main system’s power supply).
• Output Ports:
  • Multiple terminal blocks or connectors for distributing NMEA 0183 data (e.g., HDT, ROT, GGA, GLL, VTG, VHW, etc.) to various bridge equipment (radar, chartplotter, autopilot, VDR).
  • May include connections for AD-10 format data for specific Furuno equipment.
  • Possibility of dedicated alarm outputs or other control signals, especially when used with Inmarsat-C systems (e.g., connecting IC-306 Alarm Unit or IC-307 SSAS Alert Unit).
  • The number of outputs will vary based on the specific system it’s bundled with (e.g., “up to 4 connections can be made” in one description for Felcom).

Physical:

• Construction: Robust, marine-grade enclosure, typically made of metal (e.g., mild steel) or durable plastic.
• Shape: Rectangular (as indicated by some reseller listings).
• Mounting: Designed for bulkhead or surface mounting in a protected interior environment (e.g., inside a console, cabinet, or equipment room).
• Dimensions: Compact, but specific dimensions are not widely published as it’s an accessory.
• Cable Glands/Entry: Equipped with secure cable glands to ensure proper cable entry and strain relief.
• Origin: Made in Japan (consistent with Furuno products).

Environmental:

• Ingress Protection (IP) Rating: Likely designed for protection against dust and splashes (e.g., IP22 to IP5X equivalent), suitable for internal marine environments, not directly exposed to weather.
• Operating Temperature: Consistent with typical marine electronics operating ranges (e.g., -15°C to +55°C).
