MA-500TR

Product catalog summary

Overview: The MA-500TR is a Class B AIS transponder designed for non-SOLAS vessels such as pleasure crafts and small workboats. It enhances maritime safety by automatically transmitting and receiving vessel information, which is crucial for avoiding collisions and navigating safely.

Specifications: The transponder operates on frequencies 161.975 and 162.025 MHz, with a modulation type of 16K0GXW (GMSK). It supports a power supply of 12 V DC and has a current drain of 1.5 A for transmission and 0.7 A for reception. The device is compact, with dimensions of 165 x 110 x 123 mm and weighs approximately 1.0 kg.

Features: The MA-500TR includes a full dot-matrix display with adjustable backlight, IPX7 waterproof protection, and a self-diagnostics function. It supports up to 100 waypoints and features a 'Man Overboard' (MOB) button for instant waypoint setting. The device can store up to 20 received DSC messages and has a 3-line NMEA input/output for easy integration with other navigation equipment.

Display and Operation: The plotter display resembles a marine radar, supporting north-up, course-up, and range zoom from 0.125 NM to 24 NM. It includes a target list display for all detected AIS-equipped vessels and a danger list display for vessels within a 6 NM CPA and 60 minutes TCPA. The device allows for simple operation with compatible Icom VHF radios, enabling easy DSC calls without manual MMSI input.

Safety and Alerts: The MA-500TR provides collision-risk management through CPA and TCPA alerts, with visual and audio warnings. It can connect to external audio equipment for alerts even when away from the transponder.

Connectivity: The device includes a 15-pin D-SUB connector for NMEA input/output and comes with a GPS receiver, MXG-5000S, which is a 66-channel parallel GPS receiver with SBAS functionality.

Installation: The MA-500TR can be flush-mounted using the optional MB-75 kit, and it includes necessary cables for connection to VHF radios and other equipment.

Additional Information: The transponder is compliant with IEC 62287-1 standards and is designed for easy integration into existing marine communication systems. It is compatible with various Icom transceivers and supports multiple NMEA sentence formats for data input and output.

What is an AIS transponder? Class B AIS transponder An AIS transponder on your boat automatically receives information broadcast by other AlS-equipped vessels and base stations, all while your own vessel’s static and dynamic information is being transmitted. AIS signals may reach where radar cannot, showing AlS-equipped vessels that might otherwise be hidden, such as on the other side of an island or behind a larger vessel. SOLAS commercial vessels are already required to carry a Class A AIS transponder, so your position will be known by nearby large vessels. The MA-500TR increases your safety...
