PRE OWNED JRC JHS-180 JRC JHS-180 MARINE AIS

PRODUCT DATA SHEET: JRC JHS-180 CLASS-A AIS (USED/REFURBISHED)

PRODUCT OVERVIEW

The JRC JHS-180 is a high-performance, IMO-compliant Class-A AIS system designed by Japan Radio Co. for commercial shipping and SOLAS vessels. It is distinctive for its Single-Unit Transponder architecture, where the VHF transponder and antenna were integrated to reduce cabling and installation complexity. This system is highly valued as a second-hand unit for its robust build quality and its ability to interface deeply with legacy JRC Radar and ECDIS series.

KEY FEATURES & APPLICATIONS

Unique Single-Unit Structure: By combining the transponder and antenna into one housing, the JHS-180 reduces signal loss in cables and simplifies the overall bridge-to-mast wiring.

Integrated Guard Zone: Features a customizable guard zone function that can be synchronized with JRC ARPA radars to enhance collision avoidance predictability.

SOLAS Compliance: Meets all international standards (IMO MSC Res.74, ITU-R M.1371) for vessels over 300 GT on international voyages.

Fleet Identification: Includes a specialized function to display "Fellow Ship" identification, allowing fleet managers to easily distinguish company vessels from general traffic.

Reliable Data Exchange: Broadcasts own-ship data (MMSI, Name, Position, SOG, COG) and receives dynamic data from up to 200 targets simultaneously.

System Connectivity: Designed for seamless integration with JRC JMA-7000CA, JMA-9000CA, and JMA-9800 radar series via the NQD-4190 junction box.

Maintenance Support: Built-in self-diagnosis and on-line maintenance support features make it easier to troubleshoot in remote maritime environments.

TYPICAL CONDITION (USED/REFURBISHED)

Standard Set: Usually sold as a complete set including the NCM-722 Controller, NTE-180 Transponder, and the NQE-3111 Junction Box.

Tested Status: Refurbished units from ship-breakers are typically tested for transmit power (12.5W) and screen backlight consistency.

Reprogramming: As a Class-A unit, it may require a technician's code to clear the previous vessel's MMSI and static data.
