Class B AIS Transponder with
Wide Viewing-Angle Color TFT LCD
Receiving both Class A and B AIS Signals

Benefits of AIS (Automatic Identification System)

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. Using with an AIS transponder, you can find AIS mounted small boats and buoys that are difficult to be detected with a marine radar. The MA-510TR can receive both Class A and B AIS signals and increases your safety at sea.

4.3-inch Color TFT LCD

Plotter screen (Day mode)

The wide viewing, high resolution 4.3-inch color TFT display clearly shows your and other vessels’ positions. Potentially dangerous vessels are shown in red and ships registered as your friends are shown in yellow. The day-mode display is readable in direct sunlight, and the night-mode display ensures good readability in the dark for further convenience.

AIS Target List and Details

Target list screen

The ‘Target’ list screen shows all detected AIS equipped vessels and targets. The ‘Danger’ list screen shows a list of vessels that are within six nautical miles of Closest Point of Approach (CPA) and sixty minutes of Time to Closest Point of Approach (TCPA) from your vessel. The ‘Friend’ list screen displays the detected AIS targets that you set as friends. When you want to see target details, select the target by the cursor keys and push [ENT] key.

Simplified Navigation Function

Plotter screen with Navigation screen

The Navigation function guides you to a specified waypoint or AIS target. You can assign a maximum of 100 favorite fishing spots or destinations as waypoints. The Navigation function is simply started by just selecting a waypoint or an AIS target on the display.

Navigation screen

Navigation to MOB Waypoint

Plotter screen with MOB Navigation screen

When the [WPT/MOB] button is held down, the MA-510TR automatically marks a waypoint of the vessel’s current position and activates the MOB (Man Overboard) navigation function to the location the MOB event occurred.

Individual DSC Call

You can transmit an individual DSC Call by simply selecting an AIS target and the voice channel on the MA-510TR*.
* A compatible Icom VHF radio is required. The MA-510TR and a radio can be connected with the accessory cable. See the instruction manual of each for radio’s connecting instructions.

USB Connectivity

AIS data can be output from an USB cable connector on the rear panel*.
* A third party application and a connection cable are required.

Supplied GPS Antenna

Supplied GPS antenna

The GPS receiver with SBAS function is integrated in the MA-510TR. Position information can be simply received with connection to the supplied GPS antenna with 10 m, 32.8 ft cable.

NMEA 2000™, NMEA 0183/-HS Connectivity

With the plug-and-play functionality of NMEA 2000™, the MA-510TR can connect to a NMEA 2000™ network (an external plotter, marine radar and VHF radio). Using NMEA 0183/-HS connectivity, the transponder can connect to a transceiver, plotter device, marine radar, external GPS receiver, or switch button.

Collision Alarm Function

When a vessel comes into the CPA or TCPA range, the vessel’s icon blinks on the plotter display and a beep sound is heard. When connected to external audio equipment installed on the chart table or fly bridge, the collision alarm function will alert you, even when you are away from the AIS transponder.

Silent Mode for Security and Privacy

Silent mode switches off the AIS transmitter and allows you to temporarily stop transmitting your vessel’s position information. This function is useful when you do not want to reveal your fishing spots to other vessels. You can receive other vessel’s AIS reports also while the silent mode is ON.
