Features

Dual color LED backlight (New)

The JHS-183 incorporates many display modes readily available on a highly visible 4.5-inch LCD display. Besides the display being fully dimmable and backlit keys, it features dual LED backlight (white and orange), making it easy to operate in various light settings on the bridge.

No flush mount kit

With JRC’s new design approach, a flush mount kit is not required and screws are nicely concealed behind the front cover.

The JHS-183 AIS is a ship borne system capable of regularly broadcasting own ship’s unique information and continually receiving and displaying information broadcast from other vessels. The AIS can “see around corners”, allowing avoidance of dangers before visual contact has been established. All ship’s information including static and voyage related data such as the ship’s name and cargo, as well as its dynamic navigational information, i.e., position, course, and speed can be transmitted and received.

New transponder (New)

JRC’s advantage of long range reception has been the basis for this new model. The outside of the transponder is the same as its predecessor, but the inner parts have been completely updated to the latest technologies, such as digital signal processing, increased circuit integration and optimized transmission power.

Interfacing

Inter facing is made easy and costeffective. Connect your radar or ECDIS, GPS and gyro to the display and you’re all set. With the (optional) all new connection box you’ll receive all the interfacing you need for advanced networking, such as DGPS, alarm, long range, and more. A dedicated pilot plug port and LAN interfacing for maintenance or connecting to the ship’s network is also readily available.
