What Is an AIS Transponder?
/20191123152158.jpg)
An AIS transponder on your boat automatically receives information broadcast by other AIS-equipped vessel's and base stations, all while your own vessel's static and dynamic information is being transmitted. AIS signals may reach where radar cannot, showing AIS-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 at sea.
Class B AIS Transponder
The MA-500TR is a Class B AIS transponder for Non-SOLAS vessels such as pleasure craft, workboat and small vessels. Your vessels information will automatically be transmitted at fixed intervals or under base station control. The MA-500TR receives dual AIS channels (Ch. 87B and Ch. 88B) simultaneously and receives both Class A and Class B AIS information.
Transmitted information by MA-500TR is
MMSI code
Vessel name
Call sign
Type of ship
GPS antenna position
Ship's position
SOG (Speed over ground)
COG (Course over ground)
UTC date and time
GPS antenna type
PA (Position Accuracy)
Simple Operation
/20191217131028.jpg)
The Plotter display looks like a marine radar display. North-up, course-up and range zoom from 0.125 NM to 24 NM are supported. The Target list display shows all detected AIS equipped vessels and targets. The Danger list display shows a list of vessels that are within 6 NM CPA and 60 minutes TCPA from your vessel. The Danger list can be sorted by CPA or TCPA order. In addition to these display types, the Detail screen shows various information about the selected AIS target.
CPA and TCPA for Collision-Risk Management
/20191123152458.jpg)
When a vessel comes into the CPA and TCPA range, the vessel icon blinks on the Plotter display and emits a beep sound. When connected to external audio equipment installed on the deck or tower, the collision alarm function will alerts you even when you are away from the AIS transponder.
Individual DSC Call*
When connected to a compatible Icom VHF radio, it's easy to make an individual DSC call. Select a vessel using the MA-500TR's cursor keys and then push the "DSC" button on the MA-500TR. It is not required to input an MMSI number manually.* This function works only when connected to compatible Icom transceivers.
100 Waypoints Memory
Up to 100 waypoints can be stored on the waypoint list. The "MOB" button allows you to set a waypoint on your current position instantly.
Safety-Related Message
When the MA-500TR receives a safety-related message from a Class A AIS transponder, the message icon appears on the Plotter display. Up to 20 received DSC messages are automatically stored in the log memory.
3-Line NMEA Input/Output
The MA-500TR has 15-pin D-SUB connector providing 3-lines of NMEA input/output on the rear panel. The supplied NMEA connector cable simplifies the installation and connection to the VHF radio and other navigation equipment.
