Description
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.
The JHS-183 is an important piece of navigation equipment for collision avoidance and maneuvering, featuring an all new display and a transponder designed for long range reception.
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.
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
AIS-SART: 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.
