Class B AIS Transponder

The MA-500TR is a compact, waterproof Class B AIS Transponder.

It has a dual channel receiver allowing boat owners to receive AIS information (both Class A and Class B AIS signals) on two channels simultaneously. This real-time information is then displayed on its large, backlit full dot-matrix display (LCD size is 62.25mm x 62.25mm) giving the boatowner real-time vessel traffic information thus aiding navigation and collision avoidance.

The MA-500TR’s compact size means that it can for example be installed in a convenient place near the chart table, in the wheelhouse, on the fly bridge or on a pedestal in the cockpit. The MA-500TR features large, easy to use, backlit buttons that will make it easy to operate even in tough conditions.

The MA-500TR can be integrated with the Icom IC-M505* /IC-M603** allowing you to transmit DSC individual calls to a selected vessel instantly without manual MMSI entry; very handy in an emergency. The MA-500TR AIS data output uses the NMEA 0183 format for easy connectivity to most radars, chart plotters, and navigation systems.

The MA-500TR has several collision-risk management functions. It identifies a target list (those in a local area), dangerous list (those you could potentially collide with) and what the closest point of approach is. A collision alarm and external alarm connection to optional external audio equipment gives the boatowner extra warning of potential impact.
