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.

Guard zone

This function allows the user to set a guard zone, providing a visual and audible alert for any vessel entering that area.

Own group vessels

The JHS-183 incorporates a function that recognizes own group vessels. When presetting a vessel’s identification, it can easily be shown on the display


The JHS-183 supports the reception of AIS-SART signals which are automatically sorted to the top of the screen.

Self diagnosis

The built-in automatic self-diagnosis function allows easy maintenance and contributes to an ever higher system reliability.


Uniform operation

Uniform operation

In keeping with the company’s philosophy of an easy to use Man Machine Interface, the new generation displays have allowed JRC’s engineers to develop an exciting new software approach for uniform operation. The JHS-183 is able to display up to 200 AIS targets and the excellent on-screen menus will greatly shorten most users’ learning period.

About AIS

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.

Integration with navigation equipment

The JHS-183 is an important piece of navigation equipment onboard for collision avoidance and maneuvering. The information broadcast from other ships displayed on the AIS, together with the geographical information shown on the radar or ECDIS provides highly important data for strategic decisions and for prompt contact with other ships.

Remote Maintenance System (RMS)

JRC has the ability to cost-effectively monitor performance and functionality of the JHS-183 while at sea, significantly reducing downtime and maintenance costs.


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.


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.


The JHS-183 consists of just two components, display and transponder. The components are light and compact with only one coax cable between the display and transponder required. This allows for a straightforward installation approach, significantly reducing the installation time.

Long LCD life

The LCD has a life span of 50,000 hours guaranteeing many years of continuous operation – regardless of the LED backlit color selected.
